What is the evolutionary basis for sexual reproduction? Solution There are both asexual and sexual reproduction in nearly all groups of animals and plants, in neither kingdom sex developed as a more rapid means. When sexual reproduction first originated is still a question. But it is believed that sex originated in green algae. There are certain species like Ulothrix have different size of spores are produced. These spores comes in pair and become one and gives valuable new forms. In some groups of unicellular plants ,the Peridinea, the Conjugatae and the Diatomeae- there is no asexual reproduction. These are good example of the actual gametic origin. The whole process of evolution is understand by these lines that first there was a visible morphological differentiation of gametes, the one becoming a large inactive cell stored with food , the other becoming small and mobile. Then came the evolution of various sex organs, and finally the alternation of generation. There are 3 main categories of sexual life cycles: diploid-dominant, demonstrated by most animals; haploid - dominant, demonstrated by all fungi and some algae; and the alternation of generations , demonstrated by plants and some algae. The Red Queen Hyothesis- First proposed by Leigh Van Valen in 1973. According to this hypothesis are species co-evolved with other organisms like predators evolve with their prey and parasites evolve with their hosts. Each tiny advantages gained by favorable variations gives a secies an edge over close competitors, predators, parasites, or even prey. Species that cannot keep up become extinct. August Weismann proposed an explanation for the evolution of sex, where the advantages of sex is the creation of variation among siblings. A similar hypothesis proposed by Charles Darwin in his book Origin of species..

Evolution theory
This document discusses evolution and the taxonomy of living things. It defines evolution as any heritable change in a population over generations. It describes how Charles Darwin theorized that all life evolved from a common ancestor and became more complex over time. It then explains taxonomy as the classification of living things in a hierarchy of domains, kingdoms, phyla, classes, orders, families, genera and species based on their characteristics and evolutionary relationships. The document outlines the key evidence for evolution such as fossils, selective breeding, and homologous structures. It also identifies the agents that drive evolutionary change as mutations, genetic drift, gene flow and natural selection.
Classification of organisms
Robert Harding Whittaker was an American plant ecologist active from the 1950s to 1970s who established a five-kingdom classification system for life in 1969 that included Monera, Protista, Fungi, Plantae, and Animalia. Carl Woese later introduced a three-domain system in 1977 that divided Monera into Archaea and Bacteria based on evolutionary relationships. Rhizopus is a genus of common fungi found on various organic substrates that can cause opportunistic infections in humans. It reproduces asexually via sporangiospores inside spherical sporangia on stalked sporangiophores and sexually via dark zygospores formed by the fusion of compatible mycelia.

Introduction
The ability to reproduce in kind is a basic characteristic of all living things. In kind means that the offspring of any organism
closely resembles its parent or parents. Hippopotamuses give birth to hippopotamus calves; Monterey pine trees produce
seeds from which Monterey pine seedlings emerge; and adult flamingos lay eggs that hatch into flamingo chicks. In kind
does not generally mean exactly the same. While many single-celled organisms and a few multicellular organisms can
produce genetically identical clones of themselves through mitotic cell division, many single-celled organisms and most
multicellular organisms reproduce regularly using another method.
Sexual reproduction is the production by parents of haploid cells and the fusion of a haploid cell from each parent to form
a single, unique diploid cell. In multicellular organisms, the new diploid cell will then undergo mitotic cell divisions to
develop into an adult organism. A type of cell division called meiosis leads to the haploid cells that are part of the sexual
reproductive cycle. Sexual reproduction, specifically meiosis and fertilization, introduces variation into offspring that may
account for the evolutionary success of sexual reproduction. The vast majority of eukaryotic organisms can or must employ
some form of meiosis and fertilization to reproduce.
7.1 | Sexual Reproduction
By the end of this section, you will be able to:
• Explain that variation among offspring is a potential evolutionary advantage resulting from sexual reproduction
• Describe the three different life-cycle strategies among sexual multicellular organisms and their commonalities
Sexual reproduction was an early evolutionary innovation after the appearance of eukaryotic cells. The fact that most
eukaryotes reproduce sexually is evidence of its evolutionary success. In many animals, it is the only mode of reproduction.
Chapter 7 | The Cellular Basis of Inheritance 153
And yet, scientists recognize some real disadvantages to sexual reproduction. On the surface, offspring that are genetically
identical to the parent may appear to be more advantageous. If the parent organism is successfully occupying a habitat,
offspring with the same traits would be similarly successful. There is also the obvious benefit to an organism that can
produce offspring by asexual budding, fragmentation, or asexual eggs. These methods of reproduction do not require
another organism of the opposite sex. There is no need to expend energy finding or a.
Theories of preformation, pangenesis, epigenesis,
The document summarizes several historical theories of embryological development:
1) Preformation theory proposed that embryos existed preformed and fully formed within the egg or sperm, simply needing to grow larger. This was later disproven.
2) Epigenesis theory, advocated by Wolff, stated that differentiation occurs after fertilization from an undifferentiated egg or sperm, and is the universally accepted view.
3) Pangenesis theory proposed by Darwin involved "gemmules" transmitting traits, but lacked scientific basis.
4) Axial gradient theory proposed physiological gradients along the axis determine development and regeneration, with Child expanding on this view quantitatively.

Evolution
Evolution is defined as any change in the properties of populations that are inheritable from one generation to the next, ranging from slight changes in allele frequencies to major innovations like the development of complex organisms. Life began around 3-4 billion years ago as single-celled microbes. The first land plants appeared around 475 million years ago, followed by simple animals 600 million years ago and complex animals 550 million years ago. Natural selection is the process by which organisms better suited to their environment tend to survive and reproduce, while artificial selection is selective breeding by humans to emphasize desired traits. The future of life on Earth depends on the availability of water, as water is essential for all known forms of life.

Biology 1A Study Guide [SJSU] Essay
Thomas Malthus' theory that populations grow exponentially while resources increase arithmetically inspired Darwin's theory of natural selection. Malthus proposed that populations are kept in check by factors like starvation and disease. Darwin applied this concept at the individual level, realizing that traits allowing organisms to better acquire resources and avoid dangers would lead to greater survival and reproduction. He called this natural selection, where heritable traits better suited to the environment are preserved and passed on, driving evolutionary change over generations as less suited traits die out.
asexual ans sexual reproduction.pptx
Animals reproduce both sexually and asexually. Sexual reproduction involves the union of male and female gametes through internal or external fertilization. It ensures genetic variation but requires more energy. Asexual reproduction requires only one parent and copies genetic material, allowing for rapid population growth but less variation. Common methods of sexual reproduction in animals include oviparity (egg-laying), ovoviviparity (egg-retention), and viviparity (live-bearing young). The life cycles of frogs and fish are given as examples, from fertilization of eggs to metamorphosis or growth into adults.

1) The document discusses several theories of evolution including Lamarck's theory of inheritance of acquired characteristics, Darwin's theory of natural selection, and De Vries' mutation theory.
2) Lamarck believed that organisms could pass on traits acquired during their lifetime to their offspring, such as giraffes passing on long necks. Weismann disproved this through experiments on mice.
3) Darwin's theory of natural selection proposed that variations arise in populations and individuals with favorable traits are more likely to survive and pass those traits to offspring, leading to the emergence of new species over time.

briefly write about the Aridity of Subtropics Causes, locations, etc.
Solution
The Aridity of Subtropics: the differential air temperature at some specific latitudes makes
warmer weather than & some cold air currents may also trigger aridity & advection fog whereas
some warm air currents may trigger more air temperature
The main cause of aridity is due to the formation of desert weather through \"water deficiency\"
& dry climate. These causes are going to form sub-topical desert (BWh) and steppe (BSh) as
semi-arid locations in both tropical & temperate regions. The other causes are elevated
temperatures with cloudless sky and locations are Chile\'s Atacama Desert or Middle-Latitude
Desert.

test ranks all of the observations from both groups and then sums the ranks from one of the
groups which is compared with the expected rank sum. It is possible, although not very common,
for groups to have different rank sums and yet have equal or nearly equal medians..

It describes how Charles Darwin developed his theory of evolution after observing variations between species on his voyage on the HMS Beagle. Darwin proposed that organisms evolve over generations through natural selection of inheritable traits that increase an individual's chances of survival and reproduction. The document then provides examples of evidence that support evolution, including the fossil record, comparative anatomy and biochemistry, and experiments like the Miller-Urey experiment that show how basic organic molecules could have formed on early Earth.

Evolution and theories of evolution
1) The document discusses several theories of evolution including Lamarck's theory of inheritance of acquired characteristics, Darwin's theory of natural selection, and De Vries' mutation theory.
2) Lamarck believed that organisms could pass on traits acquired during their lifetime to their offspring, such as giraffes passing on long necks. Weismann disproved this through experiments on mice.
3) Darwin's theory of natural selection proposed that variations arise in populations and individuals with favorable traits are more likely to survive and pass those traits to offspring, leading to the emergence of new species over time.

briefly write about the Aridity of Subtropics Causes, locations, etc.pdf
briefly write about the Aridity of Subtropics Causes, locations, etc.
Solution
The Aridity of Subtropics: the differential air temperature at some specific latitudes makes
warmer weather than & some cold air currents may also trigger aridity & advection fog whereas
some warm air currents may trigger more air temperature
The main cause of aridity is due to the formation of desert weather through \"water deficiency\"
& dry climate. These causes are going to form sub-topical desert (BWh) and steppe (BSh) as
semi-arid locations in both tropical & temperate regions. The other causes are elevated
temperatures with cloudless sky and locations are Chile\'s Atacama Desert or Middle-Latitude
Desert.
Ocean conveyor, El Nino Southern Oscillation (ENSO): This effcet further increases the oceanic
atmospheric pressure in Pacific and finally warmer winds associated with much warmer water
leading global climate change..
Compare and contrast the Mann-Whitney (aka Wilcoxon Rank Sum) Test w.pdf
Compare and contrast the Mann-Whitney (aka Wilcoxon Rank Sum) Test with the Median test.
Discuss their similarities/differences.
Solution
the Mann-Whitney and the equivalent Wilcoxon test (hereafter called the Mann-Whitney-
Wilcoxon test) are rank sum tests and not median tests. Basically, the Mann-Whitney-Wilcoxon
test ranks all of the observations from both groups and then sums the ranks from one of the
groups which is compared with the expected rank sum. It is possible, although not very common,
for groups to have different rank sums and yet have equal or nearly equal medians..

Before the IRS can impose the accumulated earnings tax, it need only show that tax avoidance
was one of b. Long-term capital gains are included in the accumulated earnings tax base Select
the appropriate answer below the motives for the corporation\'s unreasonable accumulation of
earnings Select true/false Each corporate member of a controlled group can claim a separate
$150,000 or $250,000 accumulated earnings credit. A dividends-paid deduction can be claimed
for both cash and property distributions (other than nontaxableC- stock dividends) made by a
corporation. This deduction reduces both regular taxable income and accumulated taxable
income c. d. e. The accumulated earnings tax liability cannot be eliminated by paying a
deficiency dividend f. f Interest and penalties on the accumulated earnings tax deficiency accrue

tax is self-reported on Form 1120-AET that is filed along with the corporate tax return g. Choose
from any drop-down list and then continue to the next question
Solution
A. True - It is necessary for IRS to prove that the earnings has been accumulated by corporations
for evading tax after analysing and audting the tax return of corporation properly.
B. false - net capital gain after deducting related federal income taxes is a considered as a
negative adjustment done to get accumulated taxable income
C. false - A single AEC statutory exemption must be allocated among the members of a
controlled group.
D. False - there is no reduction in taxabl income due to dividiend paid deduction
E. True - There is not relation between payment of dificiency dividend and AET liability

Before 1980, most cell control and management software was written b.pdf
Before 1980, most cell control and management software was written by the user using the C
programming language. True False
Solution
False
The C programming language was devised in the early 1970s as a system implementation
language for the nascent Unix operating system. Derived from the typeless language BCPL, it
evolved a type structure; created on a tiny machine as a tool to improve a meager programming
environment, it has become one of the dominant languages of today
C came into being in the years 1969-1973, in parallel with the early development of the Unix
operating system; the most creative period occurred during 1972. Another spate of changes
peaked between 1977 and 1979, when portability of the Unix system was being demonstrated. In
the middle of this second period, the first widely available description of the language appeared:
The C Programming Language,often called the `white book\' or `K&R\' [Kernighan 78]. Finally,
in the middle 1980s, the language was officially standardized by the ANSI X3J11 committee,
which made further changes. Until the early 1980s, although compilers existed for a variety of
machine architectures and operating systems, the language was almost exclusively associated
with Unix; more recently, its use has spread much more widely, and today it is among the
languages most commonly used throughout the computer industry.
The late 1960s were a turbulent era for computer systems research at Bell Telephone
Laboratories [Ritchie 78] [Ritchie 84]. The company was pulling out of the Multics project
[Organick 75], which had started as a joint venture of MIT, General Electric, and Bell Labs; by
1969, Bell Labs management, and even the researchers, came to believe that the promises of
Multics could be fulfilled only too late and too expensively. Even before the GE-645 Multics
machine was removed from the premises, an informal group, led primarily by Ken Thompson,
had begun investigating alternatives..

What is a view What is it used for Give examples when a view can b.pdf
What is a view? What is it used for? Give examples when a view can be used for your project.
Solution
View is way of portraying information in a database by arranging data items in certain order by
highlighting certain items. Often thought of as Virtual table, doesn\'t store data itself but pulls out
from one or more tables.
Views are used according to purpose so that we query on selective data not whole of it. Using
views saves us lot of querying resources.
For example, people query telephone directory to search for Street Address associated with
Phone Number. We can create View which stores 2 columns namely Phone number and Street
Address ignoring all other fields..

Why is it that the Grams stain is not appropriate for acid fast ba.pdf
Why is it that the Gram\'s stain is not appropriate for acid fast bacterium?
Solution
During staining in microbiology, microbes are coloured or dyed so that their structure can be
viewed against a lighter background. There are different staining techniques such as direct(Dye
binds to the cell surface and all the microbes are stained alike),differential(based on their specific
cell surface different microbes get stained differently) special (usually a particular organelle is
targeted)and negative staining(back ground is stained instead of microbes) Gram stain is a
differential stain where the bacteria with a thick peptidoglycan layer around the cells are stained
with violet colour and those with an additional lipopolysaccharide layer will be stained pink. To
understand this lets take a look at Gram staining procedure. First of all bacterial culture is
smeared onto a glass slide and is heat fixed so that during the washes in the procedure the
bacteria stay fixed onto the slide. Primary stain crystal violet is added onto the slide and the dye
seperates into ions which penetrate or enter the cell membranes of both Gram positive and
negative cells. Next iodine is added onto the slide which forms huge complexes with crystal
violet. Then a dye remover usually called as decolouriser such as alchohol or acetone is used to
remove the stain. In Gram negative bacteria the outer most membrane is lost during the treatment
with alchohol whereas in the case of gram positive bacteria the dye is trapped inside the cell
membrane. A secondary stain saffronin is used and which gives pink colour to Gram negative
bacteria. Now coming to acid-fast bacteria, they have a compound called mycolic acid in their
cell walls and are resistant to decolourisation after the acid treatment and alchohol and hence
would not lose colour and appear violet. As we can see these organism can be easily confused
with Gram positive bacteria which also do not lose stain not because they are resistant to acids
but they have the crystal violet dye trapped in their cell membrane..
Why does this version of the swap function fail to work Is there a f.pdf
Why does this version of the swap function fail to work? Is there a fix? (Choose 2) oid swap (int
& lhs, int & rhs) Select one or more: It fails because the programmer forgot to make the
parameters call-by-reference. Of course it works ! Just look at it It clearly swaps the two
parameters! It fails OK, and we can fix it we can just reverse the order of the lines. To fix this,
we must save the the value in a local variable before making the first assignment indicated, then
instead of the second Iine, as int local = lhs; Ihs = rhs; rhs = local; It fails because the first line
destroys the old value of ihs without saving it. Then both variables have the old value of rhs in
them.
Solution
Choice d, and e are valid options.
To swap the elements, we need to first copy the value of first variable to temporary variable, then
copy the second variable to first variable, finally copy the value in temporary variable to second
variable.
So,
int local = lhs;
lhs = rhs;
rhs = local;
is the perfect way to swap two values.
The last option is the actual problem with the given code.
When we do lhs = rhs, the old value of lhs is destroyed, and now, both lhs and rhs are holding
the same value, that is the value in rhs. And then, the second operation rhs = lhs, is of no use, as
both of them are holding the same value.
Therefore, options d, and e are correct..
Which of the following is NOT a reason why heat is a bad method to ov.pdf
Which of the following is NOT a reason why heat is a bad method to overcome activation
energy? A. Heat is not specific enough compared to enzymes B. Too much heat would denature
enzymes C. Heat would allow for many enzymes to be activated, not just the ones that are
needed D. Heat does not hold enough energy to overcome most activation energies
Solution

all three major candidates were left-handed. What\'s the probability of selecting three
unrelated people who are all left-handed?
Solution
Unrelated people have independent left-handedness.
Thus,
P(all three left handed) = 0.12*0.12*0.12 = 0.001728 [answer].
The mass of a radioactive substance follows a continuous exponential.pdf
The mass of a radioactive substance follows a continuous exponential decay model, with a decay
rate parameter of 5.1% per day. Find the half-life of this substance (that is, the time it takes for
one-half the original amount in a given sample of this substance to decay).
Solution
Half life = log2/ decay constant = 0.693/ decay constant
Decay constant 5.1% = 0.051
So, Half life =0.693 /0.051 = 13.58 days.

, illegitimate usage of the system.
4) Concurrency:-
The shared access to the resources should be handled properly.
Challenges in Cloud computing :
1) Security & Privacy:-
The fact that the organization\'s data will reside outside the organization\'s firewall really raises
a serious concern.
Various types of attacks including hacking may affect multiple clients even if only one site is
attacked.These risks has to be mitigated by using proper
security applications, encrypted file-systems, using a proper storage devices to track unsual
activity across the servers .
2) Loss of control over sensitive data:-
The sensitive data that are stored in the servers has to be properly controlled.
3) Reliability and Availability:-
The frequent outages has to be avoided here. It is very important to monitor the activity of
servers using monitoring tool.
The controls that are essential to prevent security threats in distributed applications and data
include:
1) The control should protect data and integrity of system in case of invalid operation on secured
data:-
In case, a user tries to enter invalid data into the system, the control should protect the system
from such operations.
2) Unauthorized invocations should be rejected by security control.
3) Efficient protection against unauthorized users:-
Unauthorized access request by non-system users should be rejected by the control.
The auditing approach should firstly start by ensuring data integrity that is associated with
application. Control should specify the operation that can be invoked only by authorized person
while rejecting access to unauthorized users when the data resources are accessed. Irrespective of
operation, control should
select only that user which can be allowed access while restricting others non-system users.
Rules should be strictly followed by control and on the basis of defined rules, users access
should be granted or denied..

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.

What is the evolutionary basis for sexual reproductionSolution.pdf
- 1. What is the evolutionary basis for sexual reproduction? Solution There are both asexual and sexual reproduction in nearly all groups of animals and plants, in neither kingdom sex developed as a more rapid means. When sexual reproduction first originated is still a question. But it is believed that sex originated in green algae. There are certain species like Ulothrix have different size of spores are produced. These spores comes in pair and become one and gives valuable new forms. In some groups of unicellular plants ,the Peridinea, the Conjugatae and the Diatomeae- there is no asexual reproduction. These are good example of the actual gametic origin. The whole process of evolution is understand by these lines that first there was a visible morphological differentiation of gametes, the one becoming a large inactive cell stored with food , the other becoming small and mobile. Then came the evolution of various sex organs, and finally the alternation of generation. There are 3 main categories of sexual life cycles: diploid-dominant, demonstrated by most animals; haploid - dominant, demonstrated by all fungi and some algae; and the alternation of generations , demonstrated by plants and some algae. The Red Queen Hyothesis- First proposed by Leigh Van Valen in 1973. According to this hypothesis are species co-evolved with other organisms like predators evolve with their prey and parasites evolve with their hosts. Each tiny advantages gained by favorable variations gives a secies an edge over close competitors, predators, parasites, or even prey. Species that cannot keep up become extinct. August Weismann proposed an explanation for the evolution of sex, where the advantages of sex is the creation of variation among siblings. A similar hypothesis proposed by Charles Darwin in his book Origin of species.
