On the Isle of Man off the coast of Ireland, a curious cat referred to as a manx cat was described in 1845. It had long hind legs and a short tail. Further work showed that the manx characteristics were the result of a dominant M allele at a single locus. An MM zygote would not survive, but Mm genotypes produced the manx characteristics. Imagine a scenario where the M allele arises by mutation on the Isle of Man. Explain how genetic drift could cause the M allele to reach a relatively high frequency (freq(M) > 0.25), even though it has harmful effects on fitness. Solution Genetic drift is the force of evolution which causes separation of individuals of a species due to geographical isolation. This causes these organisms to survive as a separate species and evolve at their respective geographical locations. According to the information, the dominant allele M is lethal to the organisms. Inspite of this fact, the frequency of allele M is increasing on the geographical area separated due to genetic drift. This suggests that the individuals on this geographical area might possess any kind of adaptability soleley due to presence of this dominant M allele. Nevertheless, it remains highly unlikely that the homozygous MM individuals will survive even on this island due to biological failures. However, individuals with heterozygous Mm genotype must have biological benefits against any stressor/stimulus at this new location. This benefit must be promoting these individuals to survive better than any of the individuals with homozyogous genotype. Thus, this particular case of fixation of higher allele frequency of geotype M in heterozygous conditions deviates from the Hardy-Weinberg law, hence there are individuals with relatively higher frequency of allele M..

Bookmark On the Isle of Man off the coast of Ireland, a curious cat referred to as a manx cat was
described in 1845. It had long hind legs and a short tail. Further work showed that the manx
characteristics were the result of a dominant M allele at a single locus. An MM zygote would not
survive, but Mm genotypes produced the manx characteristics. Imagine a scenario where the M
allele arises by mutation on the Isle of Man. Explain how genetic drift could cause the M allele
to reach a relatively high frequency (freq(M) > 0.25), even though it has harmful effects on
fitness.
Solution
When the M allele is dominant and also deleterious when it is in the homozygous state. In the
heterozygote stage Mm, the deleterious M allele is hidden due to which the selection will not
eliminate it. The Mm genotypes are successful, so the frequency of M allele rises in the
population. So the genetic drift selection cannot eliminate the M allele completely..
Evolution.ppt
Charles Darwin traveled around the world on the HMS Beagle from 1831-1836, collecting biological specimens. This provided the foundation for his theory of evolution by natural selection, published in 1859. His theory proposed that species evolve over generations through natural selection acting on inherited variation between individuals. Variations that aid survival and reproduction in a given environment become more common, leading to evolution of new species over time. This document provides background on Darwin's voyage and life, an overview of his theory of evolution by natural selection, and various evidence that supports the theory, including fossils, anatomical similarities, embryology, biochemistry and observations of natural selection in action.
Environmental Developmental Biology.pptx
The document discusses how the environment influences embryonic development in various organisms. It provides examples of phenotypic plasticity, environmental sex determination, and how embryos adapt to their environments. Specifically, it describes how the sex of worms and alligators is determined by environmental factors like temperature rather than chromosomes. It also explains how factors like UV radiation, temperature, and day length can influence traits like coloration in butterfly and moth larvae. Finally, it discusses how UV radiation in particular can impact hatching success rates in amphibian eggs.

This document discusses the endangered plant Castilleja mollis which grows in only two locations on Santa Rosa Island. It is concerned that the population may be declining due to hybridization with the widespread native Castilleja affinis. Studies from 1995-2007 found the C. mollis population declining as temperatures increased. If hybrids with C. affinis are more heat tolerant, they may replace C. mollis over time. The document summarizes genetic and mapping research on the two populations since the 1990s which shows differing trends between the sites and evidence of hybridization. Ongoing work aims to understand the genetics and impacts of hybridization on C. mollis survival in light of climate change challenges.
Process of speciation
The document discusses several ways that natural selection can lead to speciation and the evolution of new species. It provides examples of giraffes, peppered moths, seaside sparrows, and sickle cell anemia to illustrate how genetic variations within populations allow some individuals to better adapt to their environments, leading to reproductive isolation and the emergence of new species over time.
In which of the following statements are the Hardy-Weinberg conditio.pdf
In which of the following statements are the Hardy-Weinberg conditions NOT being violated?a)
Some moths on a tree are easier to see due to their lighter color and therefore are eaten by
predators more often
Solution
Answer: e) In all statements the Hardy-Weinberg conditions are being violated
Answer:
Hardy and Weinberg described that all the possible genotypes for a gene with two alleles. The
population is not surfacing due to any of the conditions that disturb Hardy-Weinberg equilibrium
would be sufficient for the Hardy-Weinberg equation to accurately predict genotype frequencies
from allele frequencies as described below. The binomial expansion representing this is, p2 +
2pq + q2 = 1.0
Where,
p2 = proportion of homozygous dominant individuals
q2 = proportion of homozygous recessive individuals
2pq = proportion of heterozygotes.
The five principles to attain equilibrium of HW are as described below
1. No mutations
2. No natural selection
3. Very large population size
4. Radom mating
5. No immigration or emigration i.e. population must be isolated therefore allele frequencies are
the same in males and females
In case, if the high migration occurs into or out of the population, then founder effect and bottle
neck effect occurs and followed by changes in allele frequencies result in evolution of new
species occurs.
There has no selection took place, in the given example, i.e. some moths on a tree are easier to
see due to their lighter color and therefore are eaten by predators more often. There was no gene
flow in the given example, of global warming, in which a river has dried up, allowing two
different rabbit populations to mate with one another, whereas they were isolated before. The
conversion of quality habitat into farmland has greatly depleted the greater prairie chicken
populations and, as a result, their genetic diversity in which, genetic diversity occurred therefore,
these statements are the Hardy-Weinberg conditions being violated
Bottlenecking ---> the conversion of quality habitat into farmland has greatly depleted the
greater prairie chicken populations and, as a result, their genetic diversity.
Random mating happened in the given example, so that Hardy -Weinberg conditions being
violated, because male elephant seals show aggression toward other males, resulting in dominant
males with several females and other males are mating with few or no females.
For example, inbreeding occurred in the descendants of 20 survivors after severe natural
calamities on the Eastern Caroline Islands resulted in microevolution of new Pingelapese
population evolved with different genetic alleles popularly exhibited achromatopsia, color
blindness. Therefore, a new population of has evolved due to genetic drift and founder effect
within the same population after a natural calamity.
No, it is not true, because evolution is not solely depends on the individual financial situations
but it evolution is mainly depends on the \"environmental factors\", mutati.

ORIGIN OF SPECIES.pptx
This document discusses macroevolution and microevolution. Microevolution involves changes in allele frequencies within a population over a short time due to factors like mutation, gene flow, genetic drift, non-random mating, and natural selection. These small changes can accumulate over long periods to result in macroevolution, where new species, genera, and higher taxonomic groups emerge due to reproductive isolation and genetic divergence between populations. Macroevolution can occur through both allopatric speciation, where populations are geographically isolated, or sympatric speciation within overlapping populations.
2. cardenas introduction
Multifactorial inheritance is caused by a combination of environmental factors and mutations in multiple genes. Common chronic diseases like high blood pressure are often multifactorial, with genetic and environmental components both playing a role. While some genes may increase susceptibility, no single gene determines these conditions. They can occur in people with or without affected family members, and concordance rates in twins do not follow Mendelian patterns.
Genetic drift
Genetic drift refers to changes in allele frequencies in a population due to random fluctuations. Over many generations, genetic drift usually results in the loss or fixation of an allele. The rate of genetic drift depends on population size, with smaller populations experiencing greater drift due to chance fluctuations. Genetic drift can lead to loss of genetic variation and influence how populations diverge genetically over time.

Darwin
1. Evolution is the process by which life on Earth has changed over time from early forms to the diversity seen today.
2. Charles Darwin proposed the theory of evolution by natural selection in 1859, suggesting that species evolve over generations through natural selection of inheritable traits that increase survival and reproduction.
3. Speciation, the evolution of new species, occurs when reproductive barriers emerge to prevent interbreeding between populations, most often due to geographical isolation or adaptation to new environments.
Mechanisms of Evolution.ppt
There are five main mechanisms of evolution: natural selection, gene flow, genetic drift, mutations, and non-random mating. Natural selection occurs as individuals with traits better suited to their environment tend to survive and pass on their genes more than others. Gene flow introduces new alleles as individuals migrate and breed with other populations. Genetic drift is the change in allele frequencies due to chance events in small populations. Mutations provide genetic variation for natural selection to act upon. Non-random mating, like sexual selection and inbreeding, can also change allele frequencies in a population over time.

genetic crift could have a stroger influence on a gene than natural selection Agree Disagree
Chance survical of some individulas occurmed in some generations, but no every generation.
Agree Disagree All species of during beetles lay their eggs in bells in during Long lege allow
the beetles to create better during balls which improves reproductive success. Long legs were
common before the canals were bult. However, after the populations were separated became less
common in the most southern population. Would the biologist agree or disagree with the
following explanations An increase in the proportion of beetles with short legs occurred because
natural selection favored individuals with shorter legs. Agree Disagree Since there was no
migration there could be no genetic drift. Agree Disagree A disorder that causes
nearsightedness is caused by a genetic multaion. Nearsighledness was harmful to people living
on a small island because the island. Before the storm, 0.1 % of the people had this disorder. Of
the 50 people who survived the storm, 2% were nearshigted. Within a few generations, 10% of
the islanders were nearsighted. Nearsightedness must have become more common thought
natural selection. Agree Disagree Near-sightedness must have become more common though
people migrating from neighboring islands. Agree Disagree Nearsighledriess must common
through migrating from neighboring islards. Agree Disagree Nearsighteclness must have
become more common through new mutations. Agree Disagree
Solution
Answer 12- Agreed to this statement as greater variation will occur due to mutation, climatic and
environmental changes over a long period of time. So only few adaptic variation were found
among five population.
Answer 13-Agreed . Yes number of alleles will remain same .
Answer 14-Agreed. Variation may occur through long time gap. Genetic drift will cause
mutation and result in variation among 5 population.
Answer 15- Agreed. As genetic drift will have more influence than natural selection as it a
slower process than genitic drift.
Answer 16- Agreed. Similar features existed among these population , so number of death of
individual remai.
ort Answer 1) Why would migration to an island by a single p.pdf
ort Answer: 1) Why would migration to an island by a single pair of birds be likely to lead to
adaptive radiation in their descendants?
Solution
1) The law of adaptive radiation by Osborn postulates, \"each isolated region, if large and
sufficiently varied in its topography, soil, climate and vegetation, will give rise to a diverse
fauna; the larger the region and more diverse teh conditions, the greater will be the variation of
animals found\". Thus, the pair of birds entering an island will be prone to variations in
topography and biological entities leading to adaptations in their features to lead a survival. The
factors which would influence their adaptative radiation are need for food, need for safety, need
for better breeding grounds, absence of enemies, presence of unoccupied environmental niches
and isolation.
2) The incompleteness of fossils is caused by the following factors:
Most of the animals and plants do not get suitable conditions for fossilization. They are
destroyed by destructive forces.
3. a. Precursors of trilobites found in pre-Silurian rocks.
b. Fossils of transitional whale with both teeth and baleen discovered..
CrazyAntPresentation2014
Crazy ants, also known as yellow crazy ants, are an invasive species that have caused major ecological damage on Christmas Island. Biologists studied the supercolonies of crazy ants which can cover 700+ hectares and have killed an estimated 10-20 million red crabs, reducing the crab population by 20-25%. Crazy ants overwhelm and outcompete native species by forming huge supercolonies with thousands of ants per square meter. Their dense populations have severely impacted the biodiversity of Christmas Island's forest ecosystem. Residents have implemented integrated pest management including baiting and spraying to control the crazy ant populations and protect the native wildlife.

In biology evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection,
The theory of evolution is based on the idea that all species are related and gradually change.
Speciation 2013
The document discusses two patterns of speciation: gradualism (anagenesis) in which a species slowly changes over time through natural selection until it is considered a new species, and branching (cladogenesis) in which a species rapidly splits into two or more new species. Branching speciation occurs through geographic isolation of populations followed by the evolution of reproductive barriers between the isolated groups, preventing interbreeding. This process of branching is the basis for biological diversity as it leads to the formation of multiple new species from the original.
Neodarwinism or synthetic theory of evolution
Neo-Darwinism is a modified version of Darwin's theory of evolution by natural selection. It incorporates genetic variation as the raw material for evolution. Genetic variation arises from sources like mutations, recombination, and chromosomal changes. Natural selection leads to differential reproduction of adaptive variants, increasing their frequency over generations. Reproductive isolation maintains distinctiveness between species. According to Neo-Darwinism, evolution occurs through the appearance of genetic variation, its spread through populations by natural selection, and reproductive isolation leading to speciation.

What functions are carried out by the human brain Solution .pdf
What functions are carried out by the human brain?
Solution
The brain consists of three major parts: the forebrain (cerebrum and diencephalon),
midbrain (tectum and tegmentum), and hindbrain (pons, cerebellum, medulla). Often the
midbrain, pons, and medulla are referred as the brainstem.
The cerebrum or cortex is the largest part of the human brain and is divided into four
sections or lobes- the frontal lobe, parietal lobe, occipital lobe, and temporal lobe. The functions
of each lobe are:
Frontal Lobe- voluntarymotor activity, speaking ability, thought processes, reasoning, and
problem solving
Parietal Lobe- process sensory information such as temperature, pain, taste and touch; movement
and orientation
The diencephalon contains the epithalamus, thalamus and hypothalamus. Epithalmus
secretes cerebrospinal fluid. Thalamus provides limited sensory awareness of pain, temperature,
touch and pressure. The hypothalamus has important functions such as regulating body
temperature, thirst, foodintake, sleeping rhythms, pituitary glands, emotional and behavioural
patterns.
The cerebellum controls body posture, maintains muscle tone, and coordinate voluntary
muscles. The pons which serves as a bridge between the midbrain and the medulla, controls the
facial and eye muscles. The medulla controls the reflexes for vomiting, swallowing, sneezing,
coughing and hiccupping.
The mid brain is a small constricted portion covered by cerebrum. The parts of tectum
are related to optical activity and auditory functions.
The brain stem is responsible for important life functions such as breathing, heartbeat,
and blood pressure..

Agree Disagree All species of during beetles lay their eggs in bells in during Long lege allow
the beetles to create better during balls which improves reproductive success. Long legs were
common before the canals were bult. However, after the populations were separated became less
common in the most southern population. Would the biologist agree or disagree with the
following explanations An increase in the proportion of beetles with short legs occurred because
natural selection favored individuals with shorter legs. Agree Disagree Since there was no
migration there could be no genetic drift. Agree Disagree A disorder that causes
nearsightedness is caused by a genetic multaion. Nearsighledness was harmful to people living
on a small island because the island. Before the storm, 0.1 % of the people had this disorder. Of
the 50 people who survived the storm, 2% were nearshigted. Within a few generations, 10% of
the islanders were nearsighted. Nearsightedness must have become more common thought
natural selection. Agree Disagree Near-sightedness must have become more common though
people migrating from neighboring islands. Agree Disagree Nearsighledriess must common
through migrating from neighboring islards. Agree Disagree Nearsighteclness must have
become more common through new mutations. Agree Disagree
Solution
Answer 12- Agreed to this statement as greater variation will occur due to mutation, climatic and
environmental changes over a long period of time. So only few adaptic variation were found
among five population.
Answer 13-Agreed . Yes number of alleles will remain same .
Answer 14-Agreed. Variation may occur through long time gap. Genetic drift will cause
mutation and result in variation among 5 population.
Answer 15- Agreed. As genetic drift will have more influence than natural selection as it a
slower process than genitic drift.
Answer 16- Agreed. Similar features existed among these population , so number of death of
individual remai.
ort Answer 1) Why would migration to an island by a single p.pdf
ort Answer: 1) Why would migration to an island by a single pair of birds be likely to lead to
adaptive radiation in their descendants?
Solution
1) The law of adaptive radiation by Osborn postulates, \"each isolated region, if large and
sufficiently varied in its topography, soil, climate and vegetation, will give rise to a diverse
fauna; the larger the region and more diverse teh conditions, the greater will be the variation of
animals found\". Thus, the pair of birds entering an island will be prone to variations in
topography and biological entities leading to adaptations in their features to lead a survival. The
factors which would influence their adaptative radiation are need for food, need for safety, need
for better breeding grounds, absence of enemies, presence of unoccupied environmental niches
and isolation.
2) The incompleteness of fossils is caused by the following factors:
Most of the animals and plants do not get suitable conditions for fossilization. They are
destroyed by destructive forces.
3. a. Precursors of trilobites found in pre-Silurian rocks.
b. Fossils of transitional whale with both teeth and baleen discovered..
CrazyAntPresentation2014
Crazy ants, also known as yellow crazy ants, are an invasive species that have caused major ecological damage on Christmas Island. Biologists studied the supercolonies of crazy ants which can cover 700+ hectares and have killed an estimated 10-20 million red crabs, reducing the crab population by 20-25%. Crazy ants overwhelm and outcompete native species by forming huge supercolonies with thousands of ants per square meter. Their dense populations have severely impacted the biodiversity of Christmas Island's forest ecosystem. Residents have implemented integrated pest management including baiting and spraying to control the crazy ant populations and protect the native wildlife.
Komodo dragon assignment (2nd yr)
The document summarizes information about the Komodo dragon (Varanus komodoensis), including its taxonomy, natural history, conservation status, threats, husbandry requirements, and veterinary challenges. It discusses how the Komodo dragon was originally thought to kill prey with toxic bacteria but is actually venomous. Conservation efforts include the Komodo National Park and captive breeding programs. Husbandry requires large enclosures that mimic natural habitats. Veterinary challenges include administering anesthesia due to their size and treating common issues like parasites, injuries, and arthritis.
Bio 40s evolution
The document outlines 4 stages in the origin of life on Earth:
1) Abiotic synthesis of organic monomers like amino acids, sugars, lipids, and ATP.
2) Abiotic polymerization of monomers into proteins and other polymers.
3) Origin of self-replicating molecules like RNA that could fuel replication.
4) Formation of pre-cell structures that had some life-like properties but a huge gap existed between them and true cells.
Genetics in orthodontics
This document discusses genetics in orthodontics. It begins by defining genetics and key figures in the field. It then explains how genetics influences growth, development, and malocclusions. The molecular basis of inheritance is described including DNA, genes, and genetic disorders. Different modes of genetic transmission are covered. Finally, specific malocclusions like Class II and Class III are discussed and twin/pedigree studies are summarized that show the genetic influences for different traits.

Evoluton in small populatin
Evolution in small population
by HAIDER ALI
In biology evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection,
The theory of evolution is based on the idea that all species are related and gradually change.
Speciation 2013
The document discusses two patterns of speciation: gradualism (anagenesis) in which a species slowly changes over time through natural selection until it is considered a new species, and branching (cladogenesis) in which a species rapidly splits into two or more new species. Branching speciation occurs through geographic isolation of populations followed by the evolution of reproductive barriers between the isolated groups, preventing interbreeding. This process of branching is the basis for biological diversity as it leads to the formation of multiple new species from the original.
Neodarwinism or synthetic theory of evolution
Neo-Darwinism is a modified version of Darwin's theory of evolution by natural selection. It incorporates genetic variation as the raw material for evolution. Genetic variation arises from sources like mutations, recombination, and chromosomal changes. Natural selection leads to differential reproduction of adaptive variants, increasing their frequency over generations. Reproductive isolation maintains distinctiveness between species. According to Neo-Darwinism, evolution occurs through the appearance of genetic variation, its spread through populations by natural selection, and reproductive isolation leading to speciation.

What functions are carried out by the human brain Solution .pdf
What functions are carried out by the human brain?
Solution
The brain consists of three major parts: the forebrain (cerebrum and diencephalon),
midbrain (tectum and tegmentum), and hindbrain (pons, cerebellum, medulla). Often the
midbrain, pons, and medulla are referred as the brainstem.
The cerebrum or cortex is the largest part of the human brain and is divided into four
sections or lobes- the frontal lobe, parietal lobe, occipital lobe, and temporal lobe. The functions
of each lobe are:
Frontal Lobe- voluntarymotor activity, speaking ability, thought processes, reasoning, and
problem solving
Parietal Lobe- process sensory information such as temperature, pain, taste and touch; movement
and orientation
The diencephalon contains the epithalamus, thalamus and hypothalamus. Epithalmus
secretes cerebrospinal fluid. Thalamus provides limited sensory awareness of pain, temperature,
touch and pressure. The hypothalamus has important functions such as regulating body
temperature, thirst, foodintake, sleeping rhythms, pituitary glands, emotional and behavioural
patterns.
The cerebellum controls body posture, maintains muscle tone, and coordinate voluntary
muscles. The pons which serves as a bridge between the midbrain and the medulla, controls the
facial and eye muscles. The medulla controls the reflexes for vomiting, swallowing, sneezing,
coughing and hiccupping.
The mid brain is a small constricted portion covered by cerebrum. The parts of tectum
are related to optical activity and auditory functions.
The brain stem is responsible for important life functions such as breathing, heartbeat,
and blood pressure..

What are the ways to conceal theft and what are the principles of in.pdf
What are the ways to conceal theft and what are the principles of internal control?
Solution
How theft Is Concealed in the Accounting Records
The initial entry to record the transaction in the
accounting records must be made in 30 days of the
transaction.
Bank reconciliations are most often done at the end of
the month. In the process of doing a bank
reconciliation, funds disbursed by the organization that
were not booked would be revealed.
The initial entry in the accounting system is usually put
into a temporary spot (e.g., suspense account) and then
subsequently moved and placed in a final account that
will flow through to the financial statements.
Internal control is the process designed to ensure reliable financial reporting, effective and
efficient operations, and compliance with applicable laws and regulations. Safeguarding assets
against theft and unauthorized use, acquisition, or disposal is also part of internal control: The
main internal control principles include:
Establish ResponsibilitiesMaintain RecordsInsure Assets by Bonding Key EmployeesSegregate
of DutiesMandatory Employee RotationSplit Related Party ResponsibilityUse Technological
ControlsPerform Regular Independent Reviews.

Think of a freshwater pond in Idaho. Name one organism that could li.pdf
Think of a freshwater pond in Idaho. Name one organism that could live in this pond in each of
the following classification groups
Domain Eukarya Kingdom Protista:
Domain Eukarya Kingdom Plantae:
Domain Eukarya Kingdom Animalia:
Domain Eukarya Kingdom Fungi:
Solution
Firstly, it is important to note that a pond ecosystem is a freshwater ecosystem. Thus all the
organisms living in it will be having a freshwater pond ecological-niche.
Since a pond is not deep, so the sunlight can easily penetrate the water and could reach to the
bottom of the pond and can support freshwater aquatic I.e. plant life. Pond ecosystem also
supports growth of fungi, animals, and protists.
Now in the given question it is asked to write about main eukarya kingdom protists, which mean
that these are those eukaryotes that lack multicellular stage or are not plantae, animals or fungi.
Example of it living in pond is amoeba and paramecium (they are animal like freshwater
protists), whereas chlorophyll and diatoms are plant like protists.
Example of domain eukaryotes kingdom plantae are: Bryophyta and mosses.
Example of eukaryotes kingdom animals: zooplanktons and insects.
Example of eukarya kingdom fungi: aquaphila and Jeranium.

Step 1 trace the development of the male gamete Procedure 1 Time to .pdf
Step 1 trace the development of the male gamete Procedure 1 Time to Trace In this exercise, you
will trace the male and female gametes from their production in the gonads to the point at which
they meet in the uterine tube, where fertilization takes place. Step 1: Male Gamete Trace the
male gamete from its earliest stage--the spermatogonium in the seminiferous tubule--through the
stages of spermatogenesis to a mature sperm, and then through the male reproductive tract until it
exits the body and enters the uterine tube of the female reproductive tract. Trace the pathway
using Figure 16.14, and also fill in the space below. Start: spermatogonium FIGURE 16.14 Male
reproductive tract End: Uterine tube 16 Reproductive systems I UNIT 16 I 419
Solution
1: The germ cells of seminiferous tubules present near the capsule serve as spermatogonia which
divide and produce more cells by mitosis. Some of these new cells serve as primary
spermatocytes that undergo meiosis; meiosis I produces two secondary spermatocytes (n) which
is followed by meiosis II that produces four spermatids. The spermatids enter the epidydimis
where they are stored and capacitated. Vas deferens serves to transports mature sperm to the
urethra in preparation for ejaculation. Urethra serves to ejaculalte the semen during intercourse
(prostetic urethra--> membranous urethra-->penial urethra--> external urethral meatus)
2: During foetal development, few germinal cells in ovary differentiate and divide mitotically to
produce oogonia which in turn divide to produce diploid primary oocyte. In follicular prenatal
phase, the primary oocytes start first meiotic division but are transitionally suspended into
prophase stage of meiosis I. After puberty, primary oocyte resumes the division and completion
of first meiotic division produce one secondary oocyte and one polar body. The secondary
oocyte is released from ovary to fallopian tube where it fuses with sperm and completes the
meiosis II. If fertilization does not occur, the degeneration of corpus luteum cause menstruation
and the secondary oocyte is expelled out through vag alog with endometrium of uterus. (ovary-->
fallopian tube-->uterus--> vag)..

The oxygen revolution facilitated by cyanobacteria had an enormou.pdf
The \"oxygen revolution\" facilitated by cyanobacteria had an enormous impact on life in our
planet. As a result, the rising concentration of atmospheric oxygen wiped out the prokaryotic
organisms that flourished in the CO2 rich environment: none of these early prokaryotic
organisms has survived to present times. True False Kuru is caused by a neurotropic virus that
\"homes\" in the brain cells. This virus belongs to the same family of viruses that cause mad cow
disease, and it is one of the smallest life forms\" known to science. True False Lipid bilayers can
only be synthetized by biological organisms. This is supported by the rise of internal
compartmentalization seen in eukaryotic organisms. It is thought that the formation of internal
organelles in eukaryotic cells resulted from the invagination of the external cell membrane in
prokaryotic cells True False Abiogenesis is the hypothesis that life exists throughout the
universe, distributed by meteorites, planetoids and asteroids. The theory of abiogenesis proposes
that life in this planet arouse from extremophile bacteria that came from outer space trapped in
interstellar debris. True False The basic elements that are the building blocks of life in this planet
are only found in living organisms; hence, these are only of biological origin. This contradicts
the theory of abiogenesis. True False DNA is the only known source of genetic information/code
for biological organisms/systems in this planet. True False the Cretaceous mass extinction is
thought to have occurred as a result of a massive meteorite impact near the Yucatan peninsula.
The impact crater (recently located) together with the iridium deposits in the days of the planet,
supports this hypothesis. True False Reproduction, mutation, use of energy and evolution are
characteristics only of living things. True False
Solution
28)
The micro fossils discovered in the rocks more than 3.5 billion years old were the single celled
prokaryotic organisms resembling the modern bacteria. These must have evolved in absence of
oxygen. Over time, photosynthetic organisms (cyanobacteria) might have evolved increasing the
concentration of oxygen in the atmosphere. This has caused some organisms to extinct because
they could not tolerate the high oxygen levels and some organisms to develop more effective
metabolic pathways to metabolize the oxygen. The statement is true.
29)
Kuru is a neurodegenerative disease caused by abnormally folded protein agents called prions.
Mad cow disease or bovine spongiform encephalopathy or mad cow disease is also caused by a
misfolded protein agent called prion. The given statement is true.
30)
The prokaryotic cells evolved earlier were started to develop internal membranes some 2 billion
years ago, due to which the evolution of eukaryotic cells had took place. The eukaryotic
organelles like mitochondria and chloroplast resemble the prokaryotic cells. This has happened
due to establishment of symbiotic relationship bet.

John has created an incredibly successful wine operation in the Nort.pdf
John has created an incredibly successful wine operation in the Northeast. He has vineyard lands
along the Seneca and Cayuga wine trails in the Finger Lakes of New York. Many of his wineries
are considered some of the best on the East Coast, and one of them, “Jennifer T” was recently
named winery of the year by Wine Spectator magazine. In all, there are 5 different wineries
operations each in a different corporation. All 5 are in a separate S-Corporation with all the stock
owned by the parent Company Petosa Vineyards Inc, also an S-Corporation. John and his wife
Jennifer own 75% of the stock of the parent Company which means they own 75% of all of the
value of the entities. Jennifer and John are each other’s second marriage. John has three children
from his prior marriage and Jennifer has 2 children from her previous marriage. John and
Jennifer’s family have been an important part of the Company’s growth. John’s brother, Tom
became a partner in the business providing much needed capital when the wineries were in a
growth stage. Tom owns 20% of the remaining stock and he has 2 children who work at the
winery on weekends doing wine tasting, but have other jobs during the week. Jennifer’s sister
Karen owns the remaining 5% of the outstanding shares. Karen has 3 children, none of which are
involved in the wine operations. However, Karen has one son, Stephen, who has an engineering
degree from Georgia Tech and has been helpful in development of the winery’s bio-dynamic
farming operations. Stephen has expressed an interest in becoming a bigger part of the overall
operations as he enjoys the laid back lifestyle the winery offers. Jennifer has been the driving
force behind the winery’s commitment to bio-dynamic, organic farming. She has been in charge
of the vineyard operations and overall marketing. Jennifer’s two sons have also been very
involved in the winery operations. Albert received his degree from Syracuse University in
Economics and Entrepreneurship. After a few summers working as a landscaper, he learned that
he loved to work the land and has been the one to implement his mother’s organic farming
techniques at the various vineyards. Nino graduated from Syracuse University with a degree in
information studies. He has been in charge of the information systems for the wineries. He has
also been responsible for the social media and other electronic marketing methods that have
catapulted the growth in the company’s exports to other states and overseas markets. Only
Christopher, of John’s three children has been involved in the wineries. Chris, a graduate of SU’s
Whitman School of Management with a degree in accounting and the Syracuse College of Law,
has been the CFO of the Company and the lead wine maker following in his father’s footsteps. It
has been Chris’ adept touch and penchant for knowing just when to harvest the grapes that has
been crucial to the recent accolades received by various wine rating agencies. Jay and Allyson
are John’s othe.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

On the Isle of Man off the coast of Ireland, a curious cat referred .pdf
- 1. On the Isle of Man off the coast of Ireland, a curious cat referred to as a manx cat was described in 1845. It had long hind legs and a short tail. Further work showed that the manx characteristics were the result of a dominant M allele at a single locus. An MM zygote would not survive, but Mm genotypes produced the manx characteristics. Imagine a scenario where the M allele arises by mutation on the Isle of Man. Explain how genetic drift could cause the M allele to reach a relatively high frequency (freq(M) > 0.25), even though it has harmful effects on fitness. Solution Genetic drift is the force of evolution which causes separation of individuals of a species due to geographical isolation. This causes these organisms to survive as a separate species and evolve at their respective geographical locations. According to the information, the dominant allele M is lethal to the organisms. Inspite of this fact, the frequency of allele M is increasing on the geographical area separated due to genetic drift. This suggests that the individuals on this geographical area might possess any kind of adaptability soleley due to presence of this dominant M allele. Nevertheless, it remains highly unlikely that the homozygous MM individuals will survive even on this island due to biological failures. However, individuals with heterozygous Mm genotype must have biological benefits against any stressor/stimulus at this new location. This benefit must be promoting these individuals to survive better than any of the individuals with homozyogous genotype. Thus, this particular case of fixation of higher allele frequency of geotype M in heterozygous conditions deviates from the Hardy-Weinberg law, hence there are individuals with relatively higher frequency of allele M.
