Genetic Variance Between And Within Species
Genetic variance between and within species had long been thought to be controlled through the
impact of natural selection in adaptive evolution. With the publication of two independent papers
this central tenet was brought into question with the new notion of selectively neutral mutations
accounting for the majority of identified variance. This hypothesis termed the Neutral Theory of
Evolution, at first questioned, has allowed significant advances in our understanding in the impacts
of selection, genetic variance, and analysis of species history. The debate over its role in evolution is
still questioned however with recent work offering results taken by some to identify irreconcilable
divergence from the expected mechanisms of Neutral Theory reigniting the neutralist vs selectionist
debate. The neutral theory of evolution, since its inception, has become a central tenet of evolution.
Its significance in understanding evolutionary processes began with the independent publication of
two papers detailing the possible role of neutral mutations in species variance (1, 2). Identified
variance in protein sequence and the calculated rates at which they arose were thought by Motoo
Kimura, the leading proponent of Neutral Theory, to be irresolvable with adaptive selection due to
limits of the cost of selection and led to development of the Neutral Theory (3). Under this model
the majority of arising mutations are selectively neutral and their presence in a population would be

Biology 2112– The Hardy Weinberg Equilibrium Lab #3
Introduction:
1. Discuss, "in details," the importance/significance of the Hardy–Weinberg Law.
The law proves that natural selection is necessary for evolution to occur ("SparkNotes: population
genetics," 2014). The conditions set up by the Hardy–Weinberg Law allow for variability (the
existence of different alleles) and inheritance, but they eliminate natural selection ("SparkNotes:
population genetics," 2014). The fact that no evolution occurs in a population meeting these
conditions proves that evolution can only occur through natural selection ("SparkNotes: population
genetics," 2014). The Hardy–Weinberg Law allows us to estimate the effect of selection pressures ...

Discuss/Explain, "in details." The concept of gene pool and gene frequency of a population.
Gene pool is the total number of genes of every individual in an interbreeding population ("Gene
pool," 2008). A large gene pool indicates high genetic diversity, increased chances of biological
fitness, and survival ("Gene pool," 2008). A small gene pool indicates low genetic diversity, reduced
chances of acquiring biological fitness, and increased possibility of extinction ("Gene pool," 2008).
Gene pool increases when mutation occurs and survives. Gene pool decreases when the population
size is significantly reduced (e.g. famine, genetic disease, etc.) ("Gene pool," 2008). Some of the
consequences when gene pool is small are low fertility, and increased probability of acquiring
genetic diseases and deformities ("Gene pool," 2008). Gene pool gives an idea of the number of
genes, the variety of genes and the type of genes existing in a population ("Gene pool," 2008). It can
be used to help determine gene frequencies or the ratio between different types of genes in a
population ("Gene pool," 2008).
Allele frequency is a measure of the relative frequency of an allele on a genetic locus in a
population; which is usually it is expressed as a proportion or a percentage ("Allele frequency,"
2014). In population genetics, allele frequencies show the genetic diversity of a species population
or equivalently the richness of its gene pool ("Allele frequency," 2014). The frequencies

Population Genetics
In 1831, Charles Darwin, proposed a theory of evolution occurring by the process of natural
selection. This has come to be known as the Theory of Natural Selection. Darwin worked on his
theory for 20 years and after learning that Alfred Russel Wallace, another naturalist, had developed
similar ideas, the two made a joint announcement of their discovery in 1858. Darwin published 'On
the Origin of Species by Means of Natural Selection' in 1859, 28 years after he proposed his theory
of natural selection. [1]
Darwin's theory of natural selection states that evolutionary change comes through the production of
variation in each generation and differential survival of individuals with different combinations of
these variable characters. [2] ... Show more content on Helpwriting.net ...

A definitive description of Huntington's Chorea occurred, when George Huntington submitted his
article 'On chorea' to the Medical and Surgical Reporter of Philadelphia, USA, in 1872, 31 years
after Waters gave his description of the disorder. Waters ' described a disorder 'which is markedly
hereditary, very rarely makes its appearance before adult life, in all cases induces a state of more or
less perfect dementia and never ceases while life lasts'. The disease was recorded early on by
observers; however Waters' description was the first detailed description of the disease. It is believed
that the disease was present among the population at a much earlier date as it is caused by a
dominant allele. Because of its long history, and the fact that the mutation rate for Huntington's
chorea is among the lowest recorded for any inherited condition, the disease has great potential in
genealogical investigations. The Afrikaner population posed as a great source to study the disease
because of the excellent recording of the origins and history of the Afrikaner nation. The excellent
documentation facilitated efforts to trace the disease back to the earliest transmission of the gene to
South Africa.
In their research they found that the only previous attempt to investigate the genealogy of this

How Natural Processes Operate at Coastal Geographic Environment
Natural Processes are actions or events that have natural causes, which result in natural events. The
three main coastal environment processes that operate at Muriwai are Coastal Erosion, Coastal
Transportation and Coastal Deposition.
The elements that interact to produce natural processes are wind, waves and tides. Each
phenomenon at Muriwai's coastal geographic environment has been produced by interaction.
Coastal Erosion is a process at Muriwai that gradually wears away the rock particles of the earth's
surface, transporting them to another location. There are many types of processes that cause erosion

The blowhole was formed by vertical, hydraulic and mechanical erosion causing the cracks and
fissures to enlarge over time to produce this hole.
Types of wave erosion operating on the headland have produced the cave.
Wave Refraction is an important process as it influences wave erosion on Otakamiro headland and
on the beach at Muriwai (refer to Diagram 1). Wave Transportation (Longshore Drift) varies
spatially due to wave refraction. It is the process by which waves alter their course as they interact
in shallow water with the seabed along the coastline. This process produces wave erosion, which
focuses its energy on Otakamiro Point.
Diagram 1
Constructive, Destructive and Dissipative are the types of waves that operate at Muriwai that cause
erosion.
Dissipative waves are the waves usually found at Muriwai –– they lose their energy before they
reach the shore as they usually break on the offshore bar. Constructive waves are long waves with
little height that leave material at the top of the beach, building it up.
Destructive waves are erosive and carry material seawards.
Wind Erosion is the driving mechanism for Coastal Transportation and Coastal Deposition. Strong
winds have a better ability to cause erosion at Muriwai's Coastal Geographic Environment. Wind
erosion is most effective on well–drained landforms such as sand dunes. Loose particles are more
easily eroded than wet heavy soil, sand and

1. What is continental drift?
Continental drift is the gradual movement of the continents across the earth's surface through
geological time.
The theory of plate tectonics, which use to be called continental drift, is described as the movement
of the continents and sea floor across the surface of the Earth. The theory explains many odd facts
about Earth's geology, such as the present arrangement of landmasses which have stated that the
Earth's crust slowly drifts atop a liquid core.
2. What was Alfred Wegener's hypothesis for continental drift, and why was his idea not accepted?

Advantages And Disadvantages Of Coastal Management
WHAT IS COASTAL MANAGEMENT?
Coastal management refers to the technique in which natural features of the coast are maintained
and protected from the threats of coastal erosion and coastal flooding.
"Successful management of coastal areas depends on understanding the different uses of coastal
land and the physical processes impacting on the coast, such as erosion and longshore drift" (BBC,

Erosion of Shorelines Essays
Erosion of Shorelines
The erosion of shorelines is a natural process that can have beneficial or adverse impacts on the
creation and maintenance of habitats. Sands and gravels eroded from the shores of coastal bays
maintain the beach as a natural barrier between the open water and coastal wetlands. Beaches move
back and forth onshore, offshore and along shore with changing wave conditions. The finer–grained
silts and clays derived from the erosion of shorelines are sorted and carried as far as the waters of
wetlands or tidal flats, where benefits are derived from addition of the new material. However,
excessively high sediment loads can smother submerged aquatic vegetation beds, cover shellfish
beds and tidal flats, fill in riffle ... Show more content on Helpwriting.net ...
The longshore drift shapes the coastline by carrying sand from sites of high wave activity to those of
low wave activity. The volume of sand carried away from or delivered to different points along the
coast can be as much as 2,000 cubic meters per day (71,000 cubic feet), enough sand to fill an
Olympic–sized swimming pool (Nepf).
The seepage of ground water and the overland flow of surface water runoff also contribute to the
erosion of shorelines (http://www.epa.gov/OWOW/NPS/MMGI/Chapter6/ch6–4.html). The role of
ground water is most important wherever permeable subsurface layers of sand are exposed in high
bluffs along coastal bays. In these areas, the seepage of ground water into the waterway can cause
erosion at the point of exit. The surface flow of upland runoff can also dislodge sediments through
the creation of rills and gullies on the shoreline banks and bluffs
(http://www.epa.gov/OWOW/NPS/MMGI/Chapter6/ch6–4.html).
Some amount of natural erosion is necessary to provide the sediment for beaches in estuaries and
coastal bays. However, excessive erosion has occurred in the past due to development. Industrial
and private development along the world's coastlines has increased dramatically since the 1970s
(Nepf). Developers and builders completed much of this construction without taking into account
the effects of coastal erosion. New buildings were often placed too close to the existing shoreline so

The Hardy Weinberg equation is a good way of providing a null–hypothesis which can later be
paralleled to direct observations of the population, making it very useful for studying populations
and evolution (University of South Florida, 2016). Drosophila melanogaster is a good model
organism for studying evolution because the generation time for these flies is a mere two weeks
(University of South Florida, 2016). It is also small, easily observed, produces many offspring, and
is a well–studied species (University of South Florida, 2016). Body color is an important trait to
study in these flies because it can help us visually see the results of the experiment; whether the flies
evolved or not. There have been numerous studies done on Drosophila melanogaster and one such
study was by Kalmus in 1935. This study was concerned with the clock system that controlled the
time at which Drosophila adults emerged from puparia (Kalmus 1935). J.M. Rendel also did a study
on Drosophila. His focus was the differences in mating behavior that was displayed between most
species of Drosophila (Rendel 1951). For this experiment, my hypothesis was that the population
was not going to remain in Hardy–Weinberg equilibrium over the course of three generations. This
is because in Rendel's literature, he states that disturbances of mating can appear due to gene

Should we let astrology affect our thinking or perception towards life?
In today's society, astrology has been an extremely fascinating belief and study among certain social
groups. Many people are used to refer to the daily horoscope in newspapers and popular magazines.
However, a large group of scientists and philosophers such as Thagard (1978) consider that
astrology is a pseudoscience, but there is a small amount of scientific evidence on whether if it is
truly a pseudoscience or not. Some of them discuss that the psychological belief in astrology of
oneself is the consequence of his or her desperation in finding solutions to their personal problems
such as marriage and career which can somehow affect their life because of its psychological effects
(Bennett, 1998). Besides, astrology is considered as an "ancestor" of modern science which is
supported by two aspects of discussions (Thomas, 1971). Furthermore, most scientists hold the
opinion that astrology can not be trust because it is lack of scientific support. Nevertheless,
according to Fitts & Fitzgerald (1977), the fate of one person is determined at some level which is
inevitable and inescapable. Moreover, Konstantinides (2004) contradict the idea that constellations
are supposed to determine the characteristics of oneself in that everyone is different somehow even

Alfred Wegener Research Paper
Alfred Wegener
Alfred Wegener was born on November 1st, 1880 in Germany's capital city, Berlin. In university
Wegener took a variety of science classes. He specialized in meteorology, physics, and astronomy.
In 1902 Wegener began a PhD degree in astronomy. He spent a year at Berlin's famous Urania
Observatory, whose purpose was to bring astronomy to a wider public. Although he was qualified to
become a professional astronomer, Wegener worried that he may not discover anything new or
interesting in the world of astronomy. Wegener believed he could make a greater impact and
contribution in meteorology, and he did. Wegener achieved several great accomplishments

advantage of finding a mate and have a better success with attracting a mate with their courtship
song (Kyriacou et al, 1978). The male heterozygous Drosophila had a better advantage at mating
than the homozygotes, which were the ebony, and therefore we predict there will be more wild type
by the end of the experiment. METHODS: In this experiment, the instructor provided us with 30
ebony individuals and 20 wild type individuals. In order to get an exact amount of each type, we

Background Information:
The Hardy–Weinberg Principle or the Hardy–Weinberg Equilibrium Model states that "allele and
genotype frequencies in a population will remain constant from generation to generation in the
absence of other evolutionary influences" (Version, T.). In order for genetic equilibrium to be
maintained, five conditions must be met:
– Random Mating: all individuals within a population must have an equal opportunity to pass on
their alleles

– p2 + 2pq + q2 = 1 ; where 'p2' represents the homozygous dominant genotype, '2pq' represents the
heterozygous genotype, and 'q2' represents the homozygous recessive genotype
This equation is used to calculate the genotype frequency, so 1 = 100% of the population.
Hypothesis:
In a large, randomly mating population where mutations, migration, and natural selection are no
longer viable, the allele and genotypic frequencies will remain at equilibrium. If any of these
conditions are changed, then the allele and genotype frequencies will be unable to maintain genetic
equilibrium.
Variables:
Independent Variable(s) – Alleles (only 2 options)
Dependent Variable(s) – Allele Frequency, Genotype Frequency
Controlled Variable(s) – The control group is the first group of data taken with the cheerios where
there is random mating, large population (100 alleles), no mutations, no migration, and no natural

For the purpose of this experiment, I propose that if a population experiences forces such as genetic
drift, selection, and non–random mating combined, then the fittest allele will express dominance,
leading to elimination of alternative alleles, and an extreme decrease in population size. Each

how each force works on their own and then when combined.

Sea Rose Poem Analysis
Poetic analysis: Sea Rose & Brook's Paradox The poem titled Sea Rose by Hilda Doolittle tells
about a rose, but not just a rose like any other. The poem instantly begins by going against the
common connotation of a rose, the reader is given this passage "Rose, harsh rose," (line 1). When
the thought of a rose comes to mind the last word used to describe the soft petals and beautiful color
would be harsh. H.D. (Hilda Doolittle) wants us to think about this rose as not an ordinary or normal
rose but to see it as something more or something less. She goes on to say, "marred and with stint of
petals" (line 2). To mar something is to disfigure or impair the quality/appearance of something, in
this case a rose. Stint means to have an ungenerous amount; by this line we can understand that H.D.
has begun to take a rose something commonly associated with beauty and love and twist into a
disfigured and battered depiction of what it once was. The rest of the stanza goes on to say, "meagre
flower, thin, sparse of leaf,". A rose is meant to be a strong symbol of love and beauty, yet the
depiction of the rose H.D. is giving the reader goes against the preconceived notions of what a rose
should be. H.D.'s language and perception of the rose challenges to the reader to think of the rose as
something more.
In Cleanth Brooks piece "Language of Paradox" he talks about how the deconstruction of a subject
through connotative and denotative meanings creates paradox. Brooks defines paradox in his text
saying "We may permit it in epigram a special sub–variety of poetry and satire, which though useful,
we are hardly willing to allow to be poetry at all. Our prejudices force us to regard paradox as
intellectual rather than emotional, cleaver rather than profound, rational rather than divinely
irrational " (pg.28, 1947). Brooks is saying he wants the reader to understand and recognize their
knowledge and conceived notions, and to encourage a new perspective.
The next stanza gives the reader a value statement as H.D. says "more precious, than a wet rose,
single on a stem–you are caught in the drift" (stanza 2). In doing so she gives the reader a sense of
how she perceives this battered and sparse rose, not as something that has lost

Theory Of Natural Selection And Genetic Drift
Evolution is the process in which various living organisms developed and diversified over time. The
study of evolution is important because it helps understand how species adapt to changing
environments. Evolution has been studied over time by observing populations when they undergo
evolutionary mechanisms such as natural selection or genetic drift. Charles Darwin came up with
the theory of natural selection. Darwin believed that living organisms tended to survive and produce
more offspring when they were better adapted to their environment. Apart from natural selection,
genetic drift was also an important mechanism. Genetic drift occurs when the gene variant changes
due to the random testing of organisms. Populations of organisms change over time because of
natural selection and genetic drift. The Hardy–Weinberg equation is used to observe whether a
specific trait within a population is changing or not. A null– hypothesis is provided by the Hardy–
Weinberg equation that can be compared to a straightforward observation of a population. The
Hardy–Weinberg equation only remains true under the circumstances that the allele and genotype
frequencies remain the same as generations continue to come about. When no evolutionary change
has occurred, the population is said to be in Hardy–Weinberg equilibrium. Populations are rarely in
Hardy–Weinberg equilibrium. Drosophila melanogaster is a fruit fly that is commonly used in
genetic studies. Drosophila only live around two weeks.

Youth Service Proposal
I am a very active individual within my church however we do not currently have a youth services
program. This has become very popular and common in my area therefore I feel it is important to
implement a youth outreach program at my church. Drift Pentecostal Church is an adult–driven
church that has dissipated in youth over the last 10 years. Drift Pentecostal Church has not had a
youth program since the early 70 's. The program has dwindled to a mere once a week Sunday
School class that is separated by ages. With each year, the enrollment has diminished thereby
leaving our church with only 20 youth members ranging from ages 2–18 years of age. Of these
individuals, approximately 80 percent are under the age of 10. Although the pastor is very effective
at bringing in new members, it is still important to target the youth in our society today. The most
important reason, schools are no longer allowing God in their programs. With the constant fight for
separation of church and state, the youth are suffering. The importance of developing a youth
program is critical in order to drive our youth into the churches and into God 's hands. In an article

Delta Smelt Essay
Introduction
As natural resources experience an increased impact by human activities, the list of endangered
species of flora and fauna expands. This highlights the importance of bringing all aspects of
conservation efforts to the forefront. These efforts are often restricted by funding and logistical
components and so prioritization must take place to ensure the preservation of critical populations
and habitats, rather than a species in its entire historical range. It is critical to preserve genetic
diversity which, in turn, allows for the preservation of the ecological and evolutionary aspects that
are required for a species to continue to exist.
Historically, conservation efforts have been focused on intraspecific phenotypes and managing ...

The delta smelt is an estuarine fish that is endemic to the San Francisco Bay–Delta region of
California. This species was listed as endangered under the California Endangered Species Act in
2010 after extended extremely low abundance indices. The historical range of the delta smelt
extended from San Pablo Bay to Sacramento along the Sacramento River and Mossdale along the
San Joaquin River. Delta smelt became extinct in the southern region of their native range in the
1970s and experienced a steep population decline in the 1980s. The greatest factor in the decline of
the delta smelt is the anthropological impact on their native ecosystem. The introduction of invasive
species and the alteration of their habitat from variable tidal systems to leveed channels have
significantly decreased suitable habitats for certain life stages of the delta smelt. Also, the highly
controversial exportation of water from the Delta has had a major impact on delta smelt populations.
Large water pumps in the southern region of the Delta are both detrimental to delta smelt habitat and
have the direct effect of killing individuals through entrainment in the pumps. According to several

Cape Cod Erosion
Cape Cod, a little arm that sticks out into the Atlantic Ocean, is a popular destination all year round
but especially in the Summer for beachgoers. Cape Cod was formed about 18,000 years ago when
the glaciers started to melt, but how was it formed? It formed through a process called weathering
and erosion. Weathering is the process of wearing away or changing the appearance or texture of
(something) by long exposure to the water, wind, and even ice. Erosion is the process that takes the
results of weathering away by water, wind, or other natural processes. The sediment was picked up
by the glaciers and slowly eroded down towards Cape Cod. As the glaciers moved south, the warmer
weather began to melt the glaciers and they dumped their load of sediment to form Cape Cod. In
total, 3 glaciers formed Cape Cod. The middle lobe retreated first leaving behind sediment that
created the middle part of the arm (the bicep). Next the easternmost lobe retreated and the sediment
it left behind created the upper part of the arm (Provincetown). When the last glaciers melted about
18,000 years ago leaving behind an usual looking landform. Today, scientists know that the glaciers
brought the sediment because they are all different colors, textures, and all have different layers.
A big problem in Cape Cod is beach erosion. The first reason why the beaches are eroding is
because of rock jetties. Rock jetties that separate beaches interrupt the natural transfer of sand by the

The Operations Process : The Operation Process
According to ADRP 5–0, The Operations Process, "Understanding is fundamental to the
commander's ability to establish a situation's context. It is essential to effective decision making

information used to develop understanding and frame the problem."¹ Lieutenant Chard displayed
varying levels of understanding throughout the defense. Initially, on route to the drift from the
forward deployed forces, he actually passed the attacking Zulu war band and completely dismissed
them. His rationale was that they must be native auxiliaries attached to the British forces. Zulu
regiments are renowned for their use of primitive livery and uniforms, and should have been
immediately recognizable to a trained British officer. After the crushing defeat at Isandhlwana, a few
survivors arrived at the hospital. They told the freshly arrived officer that he and the garrison must
flee or face certain death at the hands of the approaching Zulu horde. Chard immediately began
consulting with his second in command, Lieutenant Gonville Bromhead, and the surgeon in charge
of the hospital to determine a course of action. Chard understood that he faced a vastly numerically
superior force and that he lacked mobility due to the hospital patients. His experience with the

the cast about to snap in two. Alfred Wegener was observing his map to see if he was lost. All of the
sudden, something clicked. His eyes jotted back and forth on the paper as he discovered that the
continents all fit together like pieces of a puzzle. Could the continents have once been connected?
Wegener introduced his hypothesis to other scientists, but they rejected this proposal after no logical
explanation as to how the continents moved was provided. In circa 1960, another scientist, J. Tuzo
Wilson, decided to reintroduce Wegener's hypothesis. Scientist took interest this time around
because Wilson, and other scientists including Harry Hess, turned Wegener's hypothesis into a

Migration And Its Effects On Population
Abstract:
Migration such as immigration or emigration is the transfer of alleles, which are responsible for
genetic variations, from the gene pool of one population to another. Therefore, it may change allele
frequencies or range due to the reproduction of the immigrated individuals. This study was
performed to see how migration modifies the effects of frequent disasters on allele frequencies in
moth populations. Migration would counteract the effects of natural disasters that increase genetic
drift by introducing new alleles into the gene pool; this allows for new combinations and increases
variability within populations. Keeping all other factors constant, PopGen was used to maneuver
Hardy–Weinberg's equilibrium parameters where different levels of migration decreases the harm
caused by frequent and occasional disaster rates in a set population. As the migratory rate increases,
the relative frequencies of each allele–"A"& "a" remained closed to 0.5, respectively, indicating that
by increasing variability, migration decreases the impacts of disaster rates on a population.
Introduction:

Essay about Alfred Wegener and the Continental Drift
Alfred Wegener was a meteorologist and astronomer. He was the first scientist to introduce the
theory of the continental drift. Wegener theorized that at one time the continents were one large
landmass or Pangaea that had drifted apart. His ideas were initially rejected by other scientists. It
was not until long after Wegener's death that proof was obtained and his theory verified.
The Life of Alfred Wegener Alfred was born in Germany in 1880 and led a very busy life. He
received a PhD in astronomy but quickly moved on to meteorology. He and his brother
experimented with kites and balloons. They set a record flying a balloon during his first expedition

Wegener's theory was met with much controversy by other scientists. The fact that he was primarily
a meteorologist and astronomer rather than a geologist further discounted his theory. Wegener
provided numerous explanations and documentation in support of his continental drift theory. He
provided two fossils as evidence. Glossopteris because it had been found on several continents that
were widely separated. Glossopteris, also known as a seed fern fossil, was too large to be
transported by the wind. The other was Mesosaurus which was a small aquatic freshwater reptile
(Lutgens & Tarbuck, 2014, p. 154). Other scientists believed this was possible because land bridges
had once existed or explained it away as drafting. Wegener most likely did not offer fossil sharks or
jellyfish as evidence due to the fact that these fish inhabit all major oceans on the planet.
He also used an Austrian geologist's theory that the continental crust, sial, was lighter than sima and
the sial layer could move across the ocean floor (Healey, 2006, para. 15). Wegener further stated that
the tides could cause the continents to move and later came to the conclusion that magma could also
be responsible for the movement. Wegener made two more journeys to Greenland to conduct
meteorological and geophysical studies. His final trek in 1930 included the examination of the
glacial sheets to provide further evidence regarding

Continental Drift Theory: Alfred Wegener
Alfred Wegener gave many facts that help prove his Continental Drift theory. Wegener's supporting
facts include fossil evidence, land features, climate evidence, and sea floor spreading. In the
beginning of Wegener's research to prove his Continental Drift theory, he found clues from fossil
evidence from millions of years ago. Different animals, such as the Cynognathus, Lystrasaurus, and
Mesosaurus gave proof that the continents have moved. The Cynognathus was a land animal, whose
fossils where found in Africa and South America. Another land animal was the Lystrasaurus, whose
fossils were found in India, Antarctica, and Africa. Neither the Lystrasaurus nor Cynognathus could
travel that great of a distance over water. Also the Lystrasurus lived in warmer climates, and today
Antarctica is not a warm climate. The Mesosaurus was a fresh water reptile that was found in fresh
water in South America and Africa. The oceans are salt water, so the continents must have been
together so the Mesosaurus could walk from lake to lake or pond to pond.
Other types of fossils, such as plants, gave climate evidence to support Wegener's theory. Second,
Wegener gave climate evidence to support his Continental Drift theory. The glossopteris is a tropical
fern that as found in Antarctica, South America, India, Australia, and Africa. "... Glossopteris grew

melanogaster over the course of several generations. Was it a result of a biological factor such as
genetic drift or natural selection or did the changes result because of chance? To answer this
question we must compare the data to the null hypothesis. The null hypothesis was there is not a
difference in the data that would be expected to happen by chance. Therefore, there are no forces
causing changes in allele frequencies. For the small population, we fail to reject the null hypothesis
and cannot support a significant difference between the allele frequencies. With the null hypothesis
being rejected, there is speculation that the changes were caused by chance or a variety of different
biological terms. As a result, a variety of different hypothesis could be formulated. Was the
population size to small so natural selection or genetic drift did not have a chance to work because
the genetic variation was limited? Did the genetic variation result completely out of chance,
resulting in not having a correlation at all to genetic drift or natural selection? This allows scientists
to form new experiments that could lead to a better understanding of the small population. An

The Cause Of Genetic Information Being Transferred By A...
Humans have been involved with genetics even before the idea of genetics existed. In the 1800s, a
monk by the name of Mendel used selection in plants and crossed them to study how traits are
passed down from parents to filial generations. Ever since then, genetics have grown over time and
it has lead to much curiosity among scientists, which have then conducted their experiments to
overcome their curiosity. That has lead to many innovations and new findings.
In the early 1920s, Fredrick Griffith conducted an experiment that proposed that bacteria are the
cause of genetic information being transferred by a process called transformation. His further
researches conducted lead him to the finding that DNA was the genetic material that passed
information (Klug et al., 2012). Avery, Mccarty and Macleod using Griffith's findings confirmed that
DNA was the material that was passed down from parents to offspring's in the form of genes. Genes
are composed of alleles that pass down traits from generation to generation.
Once alleles are inherited in a population, traits are expressed. Thus this leads to the idea of
population genetics, which is very crucial to understanding genetics. Population genetics studies the
frequency of alleles that change within a population, which influences evolution. Mathematic
principles are used to population geneticists, which predict any trends that may occur in a given
population. The hardy Weinberg principle is one of these principles.

Natural Processes are actions or events that have natural causes, which result in natural events. The
three main coastal environment processes that operate at Muriwai are Coastal Erosion, Coastal
Transportation and Coastal Deposition.
The elements that interact to produce natural processes are wind, waves and tides. Each
phenomenon at Muriwai's coastal geographic environment has been produced by interaction.
Coastal Erosion is a process at Muriwai that gradually wears away the rock particles of the earth's
surface, transporting them to another location. There are many types of processes that cause erosion
at Muriwai such as wave erosion, wind erosion and wave refraction. ... Show more content on

These types of erosion have caused the formation of several phenomena at Muriwai.
Motutara Island (stack) was produced by the formation of two caves on either side of the headland
–– forming an arch and the roof slowly eroding away due to vertical erosion.
Fisherman's Rock was produced by cliff retreat when undercutting stones are thrust at the cliff by
wave action.
The blowhole was formed by vertical, hydraulic and mechanical erosion causing the cracks and
fissures to enlarge over time to produce this hole.
Types of wave erosion operating on the headland have produced the cave.
Wave Refraction is an important process as it influences wave erosion on Otakamiro headland and
on the beach at Muriwai (refer to Diagram 1). Wave Transportation (Longshore Drift) varies
spatially due to wave refraction. It is the process by which waves alter their course as they interact
in shallow water with the seabed along the coastline. This process produces wave erosion, which
focuses its energy on Otakamiro Point.
Diagram 1
Constructive, Destructive and Dissipative are the types of waves that operate at Muriwai that cause
erosion.
Dissipative waves are the waves usually found at Muriwai –– they lose their energy before they
reach the shore as they usually break on the offshore bar. Constructive waves are long waves with
little height that leave material at the top of the beach, building it up.
Destructive waves are erosive

Genetic Variance Between And Within Species

  • 1. Genetic Variance Between And Within Species Genetic variance between and within species had long been thought to be controlled through the impact of natural selection in adaptive evolution. With the publication of two independent papers this central tenet was brought into question with the new notion of selectively neutral mutations accounting for the majority of identified variance. This hypothesis termed the Neutral Theory of Evolution, at first questioned, has allowed significant advances in our understanding in the impacts of selection, genetic variance, and analysis of species history. The debate over its role in evolution is still questioned however with recent work offering results taken by some to identify irreconcilable divergence from the expected mechanisms of Neutral Theory reigniting the neutralist vs selectionist debate. The neutral theory of evolution, since its inception, has become a central tenet of evolution. Its significance in understanding evolutionary processes began with the independent publication of two papers detailing the possible role of neutral mutations in species variance (1, 2). Identified variance in protein sequence and the calculated rates at which they arose were thought by Motoo Kimura, the leading proponent of Neutral Theory, to be irresolvable with adaptive selection due to limits of the cost of selection and led to development of the Neutral Theory (3). Under this model the majority of arising mutations are selectively neutral and their presence in a population would be ... Get more on HelpWriting.net ...

The law proves that natural selection is necessary for evolution to occur ("SparkNotes: population genetics," 2014). The conditions set up by the Hardy–Weinberg Law allow for variability (the existence of different alleles) and inheritance, but they eliminate natural selection ("SparkNotes: population genetics," 2014). The fact that no evolution occurs in a population meeting these conditions proves that evolution can only occur through natural selection ("SparkNotes: population genetics," 2014). The Hardy–Weinberg Law allows us to estimate the effect of selection pressures ... Show more content on Helpwriting.net ... Discuss/Explain, "in details." The concept of gene pool and gene frequency of a population. Gene pool is the total number of genes of every individual in an interbreeding population ("Gene pool," 2008). A large gene pool indicates high genetic diversity, increased chances of biological fitness, and survival ("Gene pool," 2008). A small gene pool indicates low genetic diversity, reduced chances of acquiring biological fitness, and increased possibility of extinction ("Gene pool," 2008). Gene pool increases when mutation occurs and survives. Gene pool decreases when the population size is significantly reduced (e.g. famine, genetic disease, etc.) ("Gene pool," 2008). Some of the consequences when gene pool is small are low fertility, and increased probability of acquiring genetic diseases and deformities ("Gene pool," 2008). Gene pool gives an idea of the number of genes, the variety of genes and the type of genes existing in a population ("Gene pool," 2008). It can be used to help determine gene frequencies or the ratio between different types of genes in a population ("Gene pool," 2008). Allele frequency is a measure of the relative frequency of an allele on a genetic locus in a population; which is usually it is expressed as a proportion or a percentage ("Allele frequency," 2014). In population genetics, allele frequencies show the genetic diversity of a species population or equivalently the richness of its gene pool ("Allele frequency," 2014). The frequencies ...

  • 5. Population Genetics In 1831, Charles Darwin, proposed a theory of evolution occurring by the process of natural selection. This has come to be known as the Theory of Natural Selection. Darwin worked on his theory for 20 years and after learning that Alfred Russel Wallace, another naturalist, had developed similar ideas, the two made a joint announcement of their discovery in 1858. Darwin published 'On the Origin of Species by Means of Natural Selection' in 1859, 28 years after he proposed his theory of natural selection. [1] Darwin's theory of natural selection states that evolutionary change comes through the production of variation in each generation and differential survival of individuals with different combinations of these variable characters.

[4] A definitive description of Huntington's Chorea occurred, when George Huntington submitted his article 'On chorea' to the Medical and Surgical Reporter of Philadelphia, USA, in 1872, 31 years after Waters gave his description of the disorder. Waters ' described a disorder 'which is markedly hereditary, very rarely makes its appearance before adult life, in all cases induces a state of more or less perfect dementia and never ceases while life lasts'. The disease was recorded early on by observers; however Waters' description was the first detailed description of the disease. It is believed that the disease was present among the population at a much earlier date as it is caused by a dominant allele. Because of its long history, and the fact that the mutation rate for Huntington's chorea is among the lowest recorded for any inherited condition, the disease has great potential in genealogical investigations. The Afrikaner population posed as a great source to study the disease because of the excellent recording of the origins and history of the Afrikaner nation. The excellent documentation facilitated efforts to trace the disease back to the earliest transmission of the gene to South Africa. In their research they found that the only previous attempt to investigate the genealogy of this disease in ... Get more on HelpWriting.net ...

The blowhole was formed by vertical, hydraulic and mechanical erosion causing the cracks and fissures to enlarge over time to produce this hole. Types of wave erosion operating on the headland have produced the cave. Wave Refraction is an important process as it influences wave erosion on Otakamiro headland and on the beach at Muriwai (refer to Diagram 1). Wave Transportation (Longshore Drift) varies spatially due to wave refraction. It is the process by which waves alter their course as they interact in shallow water with the seabed along the coastline. This process produces wave erosion, which focuses its energy on Otakamiro Point. Diagram 1 Constructive, Destructive and Dissipative are the types of waves that operate at Muriwai that cause erosion. Dissipative waves are the waves usually found at Muriwai –– they lose their energy before they reach the shore as they usually break on the offshore bar. Constructive waves are long waves with little height that leave material at the top of the beach, building it up. Destructive waves are erosive and carry material seawards. Wind Erosion is the driving mechanism for Coastal Transportation and Coastal Deposition. Strong winds have a better ability to cause erosion at Muriwai's Coastal Geographic Environment. Wind erosion is most effective on well–drained landforms such as sand dunes. Loose particles are more easily eroded than wet heavy soil, sand and

Continental drift is the gradual movement of the continents across the earth's surface through geological time. The theory of plate tectonics, which use to be called continental drift, is described as the movement of the continents and sea floor across the surface of the Earth. The theory explains many odd facts about Earth's geology, such as the present arrangement of landmasses which have stated that the Earth's crust slowly drifts atop a liquid core. 2. What was Alfred Wegener's hypothesis for continental drift, and why was his idea not accepted?

Sands and gravels eroded from the shores of coastal bays maintain the beach as a natural barrier between the open water and coastal wetlands. Beaches move back and forth onshore, offshore and along shore with changing wave conditions. The finer–grained silts and clays derived from the erosion of shorelines are sorted and carried as far as the waters of wetlands or tidal flats, where benefits are derived from addition of the new material. However, excessively high sediment loads can smother submerged aquatic vegetation beds, cover shellfish beds and tidal flats, fill in riffle ... Show more content on Helpwriting.net ... The longshore drift shapes the coastline by carrying sand from sites of high wave activity to those of low wave activity. The volume of sand carried away from or delivered to different points along the coast can be as much as 2,000 cubic meters per day (71,000 cubic feet), enough sand to fill an Olympic–sized swimming pool (Nepf). The seepage of ground water and the overland flow of surface water runoff also contribute to the erosion of shorelines (http://www.epa.gov/OWOW/NPS/MMGI/Chapter6/ch6–4.html). The role of ground water is most important wherever permeable subsurface layers of sand are exposed in high bluffs along coastal bays. In these areas, the seepage of ground water into the waterway can cause erosion at the point of exit. The surface flow of upland runoff can also dislodge sediments through the creation of rills and gullies on the shoreline banks and bluffs (http://www.epa.gov/OWOW/NPS/MMGI/Chapter6/ch6–4.html). Some amount of natural erosion is necessary to provide the sediment for beaches in estuaries and coastal bays. However, excessive erosion has occurred in the past due to development. Industrial and private development along the world's coastlines has increased dramatically since the 1970s (Nepf). Developers and builders completed much of this construction without taking into account the effects of coastal erosion. New buildings were often placed too close to the existing shoreline so that ...

The Hardy Weinberg Equilibrium Equation The main purpose of this lab was to utilize the infamous Hardy–Weinberg equilibrium equation to predict the evolutionary modifications a certain species (Drosophila melanogaster) displayed throughout different generations. For this experiment to be carried out, Drosophila melanogaster, also known as fruit flies, were used to visually represent evolutionary conceptions such as Hardy– Weinberg equilibrium equation. At the beginning of the experiment, the parent generation was observed first. Throughout the course of seven weeks, the vial was analyzed for certain changes between the two populations of Drosophila melanogaster; wild type and ebony. Although the genotypes could not be figured out, the flies were evaluated and observed based on ... Show more content on Helpwriting.net ... The Hardy Weinberg equation is a good way of providing a null–hypothesis which can later be paralleled to direct observations of the population, making it very useful for studying populations and evolution (University of South Florida, 2016). Drosophila melanogaster is a good model organism for studying evolution because the generation time for these flies is a mere two weeks (University of South Florida, 2016). It is also small, easily observed, produces many offspring, and is a well–studied species (University of South Florida, 2016). Body color is an important trait to study in these flies because it can help us visually see the results of the experiment; whether the flies evolved or not. There have been numerous studies done on Drosophila melanogaster and one such study was by Kalmus in 1935. This study was concerned with the clock system that controlled the time at which Drosophila adults emerged from puparia (Kalmus 1935). J.M. Rendel also did a study on Drosophila. His focus was the differences in mating behavior that was displayed between most species of Drosophila (Rendel 1951). For this experiment, my hypothesis was that the population was not going to remain in Hardy–Weinberg equilibrium over the course of three generations. This is because in Rendel's literature, he states that disturbances of mating can appear due to gene changes which can give rise to drastic fitness reductions of the animals that have been ...

In today's society, astrology has been an extremely fascinating belief and study among certain social groups. Many people are used to refer to the daily horoscope in newspapers and popular magazines. However, a large group of scientists and philosophers such as Thagard (1978) consider that astrology is a pseudoscience, but there is a small amount of scientific evidence on whether if it is truly a pseudoscience or not. Some of them discuss that the psychological belief in astrology of oneself is the consequence of his or her desperation in finding solutions to their personal problems such as marriage and career which can somehow affect their life because of its psychological effects (Bennett, 1998). Besides, astrology is considered as an "ancestor" of modern science which is supported by two aspects of discussions (Thomas, 1971). Furthermore, most scientists hold the opinion that astrology can not be trust because it is lack of scientific support. Nevertheless, according to Fitts & Fitzgerald (1977), the fate of one person is determined at some level which is inevitable and inescapable. Moreover, Konstantinides (2004) contradict the idea that constellations are supposed to determine the characteristics of oneself in that everyone is different somehow even for twins. At last but not least, some experts claim that people do not necessarily understand themselves and others through astrology. That is why we ... Get more on HelpWriting.net ...

  • 25. Alfred Wegener Research Paper Alfred Wegener Alfred Wegener was born on November 1st, 1880 in Germany's capital city, Berlin. In university Wegener took a variety of science classes. He specialized in meteorology, physics, and astronomy. In 1902 Wegener began a PhD degree in astronomy. He spent a year at Berlin's famous Urania Observatory, whose purpose was to bring astronomy to a wider public. Although he was qualified to become a professional astronomer, Wegener worried that he may not discover anything new or interesting in the world of astronomy. Wegener believed he could make a greater impact and contribution in meteorology, and he did. Wegener achieved several great accomplishments throughout his life but, the one we're focusing on is the theory of continental drift. Continental Drift?

With the work of other scientists who had theorized about horizontal movement of the continents over the earth's surface during different periods of geologic time, and based on his own observations from different fields of science, Wegener deduced that about 200 million years ago the supercontinent that he called "Pangaea," (means "all lands" in Greek) began to break up. Evidence Many people were skeptical and didn't believe in Wegener's radical theory. Other scientist need more proof that theses huge lands of mass were moving. So Wegener provided five pieces of evidence. If you were to look on a map what do you notice? The continents slightly look like a jigsaw puzzle.

Movie Analysis of Tokyo Drift: Fast and Furious I agree with people who say movies aren't based on real life experience, but I am pretty sure producers have specific messages to tell their audience. Movies might be long and time taking, but when there is free time to spend why not lay back and watch a good movie? Today I will be reviewing one of my favorite movies of all time, Tokyo Drift. Fast and Furious: Tokyo Drift, is one the great movies of Fast and Furious series. Fast and Furious movies have a lot of fans throughout the world and the great thing about this series is that they are all relatable and continue the story that began in the year 2001. But there is something different about Tokyo Drift that keeps it unalike with other Fast And Furious movies. This is why I will be doing a review on it. Tokyo Drift is made up of 2 words which are Tokyo and drift. Of course many people know where Tokyo is located, but not a lot of people know what the word drift means in driving vocabulary. Drifting is one the popular methods racers use to dodge, show off or enjoy while driving. There is something about drifting that every time it happens somewhere, it excites the people that know what it is. Seeing your tires burn and smoke while drifting, it gives you good vibes.

Heterozygotes, which have the wild type phenotype, have normal sight which gives them the advantage of finding a mate and have a better success with attracting a mate with their courtship song (Kyriacou et al, 1978). The male heterozygous Drosophila had a better advantage at mating than the homozygotes, which were the ebony, and therefore we predict there will be more wild type by the end of the experiment. METHODS: In this experiment, the instructor provided us with 30 ebony individuals and 20 wild type individuals. In order to get an exact amount of each type, we anesthetized the flies and counted them off by gently using a fine point paint brush. Then all 50 Drosophila were put into a population cage which had a lid that had six holes for the centrifuge tubes. Two food tubes and four clean, empty tubes were added on the first day. Each food tube consisted of half a cup full of food mixed with 6–7 milliliters of water. This was the fly medium. The food should turn blue once the water is added. Each tube was labeled with a number and with the date. Every two to three days we added one more food tube until all 6 tubes contained the fly medium. After all 6 tubes were filled, the following days after we exchanged the first food tube with a new food tube. At the end of the experiment, we fed the flies with a total of 8 food tubes.

The Hardy Weinberg Principle, No Natural Selection Design Research Question: If all five conditions mentioned within the Hardy–Weinberg Principle are met (random mating, large populations, no mutations, no migration, no natural selection), will the population remain in genetic equilibrium? Background Information: The Hardy–Weinberg Principle or the Hardy–Weinberg Equilibrium Model states that "allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences" (Version, T.). In order for genetic equilibrium to be maintained, five conditions must be met: – Random Mating: all individuals within a population must have an equal opportunity to pass on their alleles – Large Populations: random changes in allele ...

Hypothesis: In a large, randomly mating population where mutations, migration, and natural selection are no longer viable, the allele and genotypic frequencies will remain at equilibrium. If any of these conditions are changed, then the allele and genotype frequencies will be unable to maintain genetic equilibrium. Variables: Independent Variable(s) – Alleles (only 2 options) Dependent Variable(s) – Allele Frequency, Genotype Frequency Controlled Variable(s) – The control group is the first group of data taken with the cheerios where there is random mating, large population (100 alleles), no mutations, no migration, and no natural selection. Control of Variables: In this experiment, in order to conform to the requirements of the Hardy–Weinberg Principle, it is necessary to control five differing factors: 1. Random Mating 2.

  • 41. Sea Rose Poem Analysis Poetic analysis: Sea Rose & Brook's Paradox The poem titled Sea Rose by Hilda Doolittle tells about a rose, but not just a rose like any other. The poem instantly begins by going against the common connotation of a rose, the reader is given this passage "Rose, harsh rose," (line 1). When the thought of a rose comes to mind the last word used to describe the soft petals and beautiful color would be harsh. H.D. (Hilda Doolittle) wants us to think about this rose as not an ordinary or normal rose but to see it as something more or something less. She goes on to say, "marred and with stint of petals" (line 2). To mar something is to disfigure or impair the quality/appearance of something, in this case a rose. Stint means to have an ungenerous amount; by this line we can understand that H.D. has begun to take a rose something commonly associated with beauty and love and twist into a disfigured and battered depiction of what it once was. The rest of the stanza goes on to say, "meagre flower, thin, sparse of leaf,". A rose is meant to be a strong symbol of love and beauty, yet the depiction of the rose H.D. is giving the reader goes against the preconceived notions of what a rose should be. H.D.'s language and perception of the rose challenges to the reader to think of the rose as something more. In Cleanth Brooks piece "Language of Paradox" he talks about how the deconstruction of a subject through connotative and denotative meanings creates paradox. Brooks defines paradox in his text saying "We may permit it in epigram a special sub–variety of poetry and satire, which though useful, we are hardly willing to allow to be poetry at all. Our prejudices force us to regard paradox as intellectual rather than emotional, cleaver rather than profound, rational rather than divinely irrational " (pg.28, 1947). Brooks is saying he wants the reader to understand and recognize their knowledge and conceived notions, and to encourage a new perspective. The next stanza gives the reader a value statement as H.D. says "more precious, than a wet rose, single on a stem–you are caught in the drift" (stanza 2). In doing so she gives the reader a sense of how she perceives this battered and sparse rose, not as something that has lost ... Get more on HelpWriting.net ...

  • 43. Theory Of Natural Selection And Genetic Drift Evolution is the process in which various living organisms developed and diversified over time. The study of evolution is important because it helps understand how species adapt to changing environments. Evolution has been studied over time by observing populations when they undergo evolutionary mechanisms such as natural selection or genetic drift. Charles Darwin came up with the theory of natural selection. Darwin believed that living organisms tended to survive and produce more offspring when they were better adapted to their environment. Apart from natural selection, genetic drift was also an important mechanism. Genetic drift occurs when the gene variant changes due to the random testing of organisms. Populations of organisms change over time because of natural selection and genetic drift. The Hardy–Weinberg equation is used to observe whether a specific trait within a population is changing or not. A null– hypothesis is provided by the Hardy– Weinberg equation that can be compared to a straightforward observation of a population. The Hardy–Weinberg equation only remains true under the circumstances that the allele and genotype frequencies remain the same as generations continue to come about. When no evolutionary change has occurred, the population is said to be in Hardy–Weinberg equilibrium. Populations are rarely in Hardy–Weinberg equilibrium.

Drift Pentecostal Church is an adult–driven church that has dissipated in youth over the last 10 years. Drift Pentecostal Church has not had a youth program since the early 70 's. The program has dwindled to a mere once a week Sunday School class that is separated by ages. With each year, the enrollment has diminished thereby leaving our church with only 20 youth members ranging from ages 2–18 years of age. Of these individuals, approximately 80 percent are under the age of 10. Although the pastor is very effective at bringing in new members, it is still important to target the youth in our society today. The most important reason, schools are no longer allowing God in their programs. With the constant fight for separation of church and state, the youth are suffering. The importance of developing a youth program is critical in order to drive our youth into the churches and into God 's hands. In an article written by Mark Howard, he wrote, "the youth are restless, insecure, jaded, and desperately searching for meaning to explain all the hurt and suffering they see around them, meaning for their very existence," therefore what the youth need most is the gospel of Christ Jesus.

The delta smelt is an estuarine fish that is endemic to the San Francisco Bay–Delta region of California. This species was listed as endangered under the California Endangered Species Act in 2010 after extended extremely low abundance indices. The historical range of the delta smelt extended from San Pablo Bay to Sacramento along the Sacramento River and Mossdale along the San Joaquin River. Delta smelt became extinct in the southern region of their native range in the 1970s and experienced a steep population decline in the 1980s. The greatest factor in the decline of the delta smelt is the anthropological impact on their native ecosystem. The introduction of invasive species and the alteration of their habitat from variable tidal systems to leveed channels have significantly decreased suitable habitats for certain life stages of the delta smelt. Also, the highly controversial exportation of water from the Delta has had a major impact on delta smelt populations. Large water pumps in the southern region of the Delta are both detrimental to delta smelt habitat and have the direct effect of killing individuals through entrainment in the pumps.

Cape Cod was formed about 18,000 years ago when the glaciers started to melt, but how was it formed? It formed through a process called weathering and erosion. Weathering is the process of wearing away or changing the appearance or texture of (something) by long exposure to the water, wind, and even ice. Erosion is the process that takes the results of weathering away by water, wind, or other natural processes. The sediment was picked up by the glaciers and slowly eroded down towards Cape Cod. As the glaciers moved south, the warmer weather began to melt the glaciers and they dumped their load of sediment to form Cape Cod. In total, 3 glaciers formed Cape Cod. The middle lobe retreated first leaving behind sediment that created the middle part of the arm (the bicep). Next the easternmost lobe retreated and the sediment it left behind created the upper part of the arm (Provincetown). When the last glaciers melted about 18,000 years ago leaving behind an usual looking landform. Today, scientists know that the glaciers brought the sediment because they are all different colors, textures, and all have different layers. A big problem in Cape Cod is beach erosion. The first reason why the beaches are eroding is because of rock jetties. Rock jetties that separate beaches interrupt the natural transfer of sand by the tides and wind. The ...

His rationale was that they must be native auxiliaries attached to the British forces. Zulu regiments are renowned for their use of primitive livery and uniforms, and should have been immediately recognizable to a trained British officer. After the crushing defeat at Isandhlwana, a few survivors arrived at the hospital. They told the freshly arrived officer that he and the garrison must flee or face certain death at the hands of the approaching Zulu horde. Chard immediately began consulting with his second in command, Lieutenant Gonville Bromhead, and the surgeon in charge of the hospital to determine a course of action. Chard understood that he faced a vastly numerically superior force and that he lacked mobility due to the hospital patients.

Alfred Wegener was observing his map to see if he was lost. All of the sudden, something clicked. His eyes jotted back and forth on the paper as he discovered that the continents all fit together like pieces of a puzzle. Could the continents have once been connected? Wegener introduced his hypothesis to other scientists, but they rejected this proposal after no logical explanation as to how the continents moved was provided. In circa 1960, another scientist, J. Tuzo Wilson, decided to reintroduce Wegener's hypothesis. Scientist took interest this time around because Wilson, and other scientists including Harry Hess, turned Wegener's hypothesis into a scientific theory that explains that the continents moved, how they moved, and that they are still moving today. A few crucial pieces of evidence that the continents moved are Wegener's observations. Although scientists disregarded his studies, he did have pieces of substantial evidence that the continents had moved. First is his evidence from fossils.

  • 62. Migration And Its Effects On Population Abstract: Migration such as immigration or emigration is the transfer of alleles, which are responsible for genetic variations, from the gene pool of one population to another. Therefore, it may change allele frequencies or range due to the reproduction of the immigrated individuals. This study was performed to see how migration modifies the effects of frequent disasters on allele frequencies in moth populations. Migration would counteract the effects of natural disasters that increase genetic drift by introducing new alleles into the gene pool; this allows for new combinations and increases variability within populations. Keeping all other factors constant, PopGen was used to maneuver Hardy–Weinberg's equilibrium parameters where different levels of migration decreases the harm caused by frequent and occasional disaster rates in a set population. As the migratory rate increases, the relative frequencies of each allele–"A"& "a" remained closed to 0.5, respectively, indicating that by increasing variability, migration decreases the impacts of disaster rates on a population. Introduction: Population genetics is the study of alleles' frequency changes and distributions in response to the five factors that drive evolution– natural selection, mutation, migration and genetic drift, within populations (McDonald and Linde, 2002). It focuses on interbreeding populations' overall gene pool, and whether the present alleles changes over time. Alleles are gene variants at a loci in a ... Get more on HelpWriting.net ...

It was not until long after Wegener's death that proof was obtained and his theory verified. The Life of Alfred Wegener Alfred was born in Germany in 1880 and led a very busy life. He received a PhD in astronomy but quickly moved on to meteorology. He and his brother experimented with kites and balloons.

Wegener's theory was met with much controversy by other scientists. The fact that he was primarily a meteorologist and astronomer rather than a geologist further discounted his theory. Wegener provided numerous explanations and documentation in support of his continental drift theory. He provided two fossils as evidence. Glossopteris because it had been found on several continents that were widely separated. Glossopteris, also known as a seed fern fossil, was too large to be transported by the wind. The other was Mesosaurus which was a small aquatic freshwater reptile (Lutgens & Tarbuck, 2014, p. 154). Other scientists believed this was possible because land bridges had once existed or explained it away as drafting. Wegener most likely did not offer fossil sharks or jellyfish as evidence due to the fact that these fish inhabit all major oceans on the planet. He also used an Austrian geologist's theory that the continental crust, sial, was lighter than sima and the sial layer could move across the ocean floor (Healey, 2006, para. 15). Wegener further stated that the tides could cause the continents to move and later came to the conclusion that magma could also be responsible for the movement. Wegener made two more journeys to Greenland to conduct meteorological and geophysical studies. His final trek in 1930 included the examination of the glacial sheets to provide further evidence regarding ... Get more on HelpWriting.net ...

  • 66. Continental Drift Theory: Alfred Wegener Alfred Wegener gave many facts that help prove his Continental Drift theory. Wegener's supporting facts include fossil evidence, land features, climate evidence, and sea floor spreading. In the beginning of Wegener's research to prove his Continental Drift theory, he found clues from fossil evidence from millions of years ago. Different animals, such as the Cynognathus, Lystrasaurus, and Mesosaurus gave proof that the continents have moved. The Cynognathus was a land animal, whose fossils where found in Africa and South America. Another land animal was the Lystrasaurus, whose fossils were found in India, Antarctica, and Africa. Neither the Lystrasaurus nor Cynognathus could travel that great of a distance over water. Also the Lystrasurus lived in warmer climates, and today Antarctica is not a warm climate. The Mesosaurus was a fresh water reptile that was found in fresh water in South America and Africa. The oceans are salt water, so the continents must have been together so the Mesosaurus could walk from lake to lake or pond to pond. Other types of fossils, such as plants, gave climate evidence to support Wegener's theory. Second, Wegener gave climate evidence to support his Continental Drift theory. The glossopteris is a tropical fern that as found in Antarctica, South America, India, Australia, and Africa. "... Glossopteris grew in temperate climates, the places where fossils had been found were once closer to the equator," (Tarbuck and Lutgens, 2011). The plant ... Get more on HelpWriting.net ...

They are found in two isolated population, firstly in the Virunga Volcanoes region which covers Uganda's Mgahinga Gorilla National Park, Rwanda's Volcanoes National Park and Democratic Republic of Congo's Virunga National Park , and secondly in the Bwindi Impenetrable National Park in south–western Uganda (Robbins & Williamson , 2008) Research by Kalpers et al. in 2003 and Gray et al in 2006 have place the population in Virunga at 380 with approximately 300 in Bwindi (McNeilage et al. 2006). The population is believed to be undergoing a significant reduction (Robbins and Robbins, 2004) and has been listed as Endangered on the IUCN Red List of Threatened Species since 2000. All the threats to these two populations are from humans – disturbance, disease transmission, habitat destruction for firewood and farmland, cattle grazing, illegal timber extraction, incursions by militia, illegal hunting, snares set for other mammals, poaching for the illegal pet trade and bushmeat etc. (Robbins & Williamson, 2008). There is a broad assumption that genetic diversity in wild populations is directly related to population size and consequently species that show recent decline have reduced variation (Vigilant & Bradley, 2004) with such a small, stressed and declining population genetic diversity within this subspecies becomes more important.

There are two ways of evolution taking place. There is microevolution and macroevolution. Microevolution is gene frequency. Macroevolution is speciation. There are two types of barriers that can be formed that would cause speciation to occur. Allopatric speciation is a physical barrier that separates a species long enough for speciation, such as a dam that was built. Sympatric speciation is speciation occurs without a geographic separation, such a mutation that caused a bird to sing a different song. Mutation can happen in many different ways. There is chromosomal alterations such as deletion, duplication, inversion, ... Show more content on Helpwriting.net ... Competition is when organisms compete for resources. Not all organisms are created equal. This differences in the organism 's fitness is called differential in fitness. How does this apply to humans? Humans are mutating right now. Some are caused by genes, while some are caused by the environment. Dwarfism is usually caused by genes, and will make the person small in stature. Osteoporosis is usually caused by the environment, and will the person 's bones weak and brittle. Dwarfism is usually caused by genes. Achondroplasia is a skeletal condition which causes dwarfism. Some adult heights were recorded as short as 64 cm. Some Dwarfs can be proportionate or disproportionate. This is usually because of the inhibition of the development of bones. Dwarfism is caused by the FGFR3 gene. A person with achondroplasia and with two average–size parents received one mutated copy of the gene and one normal copy of the gene. A person with achondroplasia may pass along either a mutated or normal gene to their own children. There is no real, all around treatment, due to the skeletal disorders, but in certain cases of pituitary dwarfism, it can be treated by giving human growth hormone. Since the bones grow if different ways, sometimes surgeries that can correct some of the displacement of the bones are needed. This is usually done with limbs and mainly the spinal cord.

Most of you know me and for the ones who do not, I am Mabel Dodge. I am the daughter from a family in Buffalo and had what was considered the best education for girls in the nineteenth– century. Instead of going to college, I got married, became a mother and soon, a widow. Later, I traveled abroad and soon married a Boston architect, Edwin Dodge who I later realized the passion I had was no more– so I divorced him. I became bored and began to crave art, the beauty and inspiration! A "salon" in Florence, Italy that I created for the purpose of attracting the most up– and– coming artists in Europe, had me become well known and even a muse for one of Gertrude Stein's image poems. I reluctantly joined Edwin my husband at the time, who was eager to come back to the United States. I settled in an apartment on the lower Fifth Avenue which most of you have been in for my "evenings" of controversial debates. What will women do with their new freedom? Not turn evil as many of you would think. Women could create lives for themselves, become economically independent and independent throughout. There are opportunities for women outside of the home. There is a whole other life outside the house. Yes, some women will have to learn to govern themselves but that is only because they were never given the chance to in their lives before.

Some of the screenwriters in the movie are Chris Morgan, Gary Scott Thompson and some of the major stars consist of Vin Diesel, Jason Statham, and Dwayne Johnson. Many of the characters are the same from the previous movies. In the beginning of the Fate of the Furious, Vin Diesel, who plays Dominic Toretto ("Dom"), is in Cuba with his wife and he is trying to help his cousin win his car back from this guy. Dominic and this guy race to win the car, using his cousin's car and the Cuban guy used his car. At the end of the race his cousin's car was on fire and then ended up in the ocean, but Dominic ended up winning the race. The deal was that if he won the race, the cuban guy had to give him his car, but Dominic was nice enough to let him keep his car. The next day, Dominic ran into an old "friend", Cipher and she was trying to get him to help her with a plan she had, when really she was manipulating him. After that scene in the movie, it moves onto Dwayne Johnson, who plays Luke Hobbs, and he was coaching his daughter's soccer team when a government agent showed up and told him that he needed to gather up his team and go to work. His team included Dominic, Roman, Tej, Megan, and Letty (the A Team) and while on their mission Dominic went rogue stole the thing that him and his team were on the mission for and took it to Cipher.

  • 76. Factors That Caused Allele Frequencies The overall goal of the experiment was to determine what caused allele frequencies to change in D. melanogaster over the course of several generations. Was it a result of a biological factor such as genetic drift or natural selection or did the changes result because of chance? To answer this question we must compare the data to the null hypothesis. The null hypothesis was there is not a difference in the data that would be expected to happen by chance. Therefore, there are no forces causing changes in allele frequencies. For the small population, we fail to reject the null hypothesis and cannot support a significant difference between the allele frequencies. With the null hypothesis being rejected, there is speculation that the changes were caused by chance or a variety of different biological terms. As a result, a variety of different hypothesis could be formulated. Was the population size to small so natural selection or genetic drift did not have a chance to work because the genetic variation was limited? Did the genetic variation result completely out of chance, resulting in not having a correlation at all to genetic drift or natural selection? This allows scientists to form new experiments that could lead to a better understanding of the small population. An example would be to continue this similar experiment but to increase the size of the small population from a total of 8 flies to a total of 60 flies. This would allow the population to actually show if genetic ... Get more on HelpWriting.net ...

In the libertine racing world Dom and Brian inhabit, they are constantly surrounded by impossibly hot and willing women. They not only faithfully go home to Letty and Mia every night, they're not even tempted with any hot women outside there. A well–crafted film can explore moral themes through characters that commit immoral acts. Other than my faith, individual freedom is a value I hold higher than any other, and this is the theme that drives the first five films more than any other. Like many of the cinema's greatest anti–heroes, Dom, Letty, and Mia live outside the law. The films, however, are not justifying or even making glamorous their criminality. The proof of this is that while we admire their free spirits and refusal to conform, we also root for them to reform their criminal ways. Dom represents the best of America, and a dying breed in Hollywood: the rugged, stoic, masculine American individualist with his own honour code. Dominic Toretto is Gary Cooper, John Wayne. He may live in East L.A., but he's really a cowboy roaming the West living by his own rules.

  • 80. The Cause Of Genetic Information Being Transferred By A... Humans have been involved with genetics even before the idea of genetics existed. In the 1800s, a monk by the name of Mendel used selection in plants and crossed them to study how traits are passed down from parents to filial generations. Ever since then, genetics have grown over time and it has lead to much curiosity among scientists, which have then conducted their experiments to overcome their curiosity. That has lead to many innovations and new findings. In the early 1920s, Fredrick Griffith conducted an experiment that proposed that bacteria are the cause of genetic information being transferred by a process called transformation. His further researches conducted lead him to the finding that DNA was the genetic material that passed information (Klug et al., 2012). Avery, Mccarty and Macleod using Griffith's findings confirmed that DNA was the material that was passed down from parents to offspring's in the form of genes. Genes are composed of alleles that pass down traits from generation to generation. Once alleles are inherited in a population, traits are expressed. Thus this leads to the idea of population genetics, which is very crucial to understanding genetics. Population genetics studies the frequency of alleles that change within a population, which influences evolution. Mathematic principles are used to population geneticists, which predict any trends that may occur in a given population. The hardy Weinberg principle is one of these principles. Hardy ...

Coastal Geographic Environment Analysis How Natural Processes Operate at Coastal Geographic Environment Natural Processes are actions or events that have natural causes, which result in natural events. The three main coastal environment processes that operate at Muriwai are Coastal Erosion, Coastal Transportation and Coastal Deposition. The elements that interact to produce natural processes are wind, waves and tides. Each phenomenon at Muriwai's coastal geographic environment has been produced by interaction. Coastal Erosion is a process at Muriwai that gradually wears away the rock particles of the earth's surface, transporting them to another location. There are many types of processes that cause erosion at Muriwai such as wave erosion, wind erosion and wave refraction. ... Show more content on Helpwriting.net ... These types of erosion have caused the formation of several phenomena at Muriwai. Motutara Island (stack) was produced by the formation of two caves on either side of the headland –– forming an arch and the roof slowly eroding away due to vertical erosion. Fisherman's Rock was produced by cliff retreat when undercutting stones are thrust at the cliff by wave action. The blowhole was formed by vertical, hydraulic and mechanical erosion causing the cracks and fissures to enlarge over time to produce this hole. Types of wave erosion operating on the headland have produced the cave. Wave Refraction is an important process as it influences wave erosion on Otakamiro headland and on the beach at Muriwai (refer to Diagram 1). Wave Transportation (Longshore Drift) varies spatially due to wave refraction. It is the process by which waves alter their course as they interact in shallow water with the seabed along the coastline. This process produces wave erosion, which focuses its energy on Otakamiro Point. Diagram 1 Constructive, Destructive and Dissipative are the types of waves that operate at Muriwai that cause erosion. Dissipative waves are the waves usually found at Muriwai –– they lose their energy before they reach the shore as they usually break on the offshore bar. Constructive waves are long waves with little height that leave material at the top of the beach, building it up. Destructive waves are erosive
