I'm thinking it's the founder effect, which according to something I found on the Internet is genetic variation from when a population originates from a small amount of species.
Bottleneck effect led to over-representation of certain alleles in the new gene pool. Therefore, option (C) is correct.
The phenomenon known as the bottleneck effect takes place when a population suffers a significant decrease in size, which leads to a reduction in the amount of genetic variation in the population. In this hypothetical situation, the clearing of land for new construction and the introduction of new structures led to a small group of birds becoming cut off from the larger, original population of birds.
Due to the fact that this small group was kept apart from the larger population, a phenomenon known as a bottleneck effect occurred. This caused the gene pool to become strikingly dissimilar to that of the original population as a result of the overrepresentation of certain alleles in the new gene pool. As a result, the response that should be chosen is option C.

What happen to the brain and the brain cavity?
Answer: OK so The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).Survival in untreated hydrocephalus is poor. Approximately, 50% of the affected patients die before three years of age and approximately 80% die before reaching adulthood. Treatment markedly improves the outcome for hydrocephalus not associated with tumors, with 89% and 95% survival in two case studies

Answer:
cranial cavity
The cranial cavity, also known as intracranial space, is the space within the skull that accommodates the brain. The skull minus the mandible is called the cranium. The cavity is formed by eight cranial bones known as the neurocranium that in humans includes the skull cap and forms the protective case around the brain.

Answer:
camoflauge and predation, say that a bird likes to eat a species of insects. some of the insects are green and others are black. since the bird will easily spot the black ones first against a green leaf, the black insect population will die out, and only green insects get to reproduce and in turn only produce green insects. this decreases the frequency of genes that make them black

All of the following are elements except
a.
water
b.
oxygen
c.
nitrogen
d.
hydrogen
Answer:
a. water
Explanation:
hello! all of the following are elements except a. water, because an element is a substance consisting of only one type of atom. water consists of two types of atoms: hydrogen and oxygen.
All of the following are elements except water which is a compound.
What is an element?An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all in solid state at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons which are present in the nucleus are the defining property of an element and are related to the atomic number.All atoms with same atomic number are atoms of same element.Different elements combine to form substances which are called as compounds.

In the space below, discuss some of the advantages and disadvantages of asexual and sexual reproduction. Compare and contrast individuals that are sexually and asexually reproduced. Use complete, meaningful sentences to explain the information you give as your answer.
Answer:
The advantages of sexual reproduction:
produces genetic variation in the offspring
the species can adapt to new environments due to variation, which gives them a survival advantage
a disease is less likely to affect all the individuals in a population
In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.
The advantages of asexual reproduction include:
the population can increase rapidly when the conditions are favourable
only one parent is needed
it is more time and energy efficient as you don't need a mate
it is faster than sexual reproduction
The disadvantages of sexual reproduction:
time and energy are needed to find a mate
it is not possible for an isolated individual to reproduce
The disadvantages of asexual reproduction include:
it does not lead to genetic variation in a population
the species may only be suited to one habitat
disease may affect all the individuals in a population

Answer:
It prevents the cell from passing on those defects to other cells through DNA replication in cell division. By self destructing before it gets the chance to divide, whatever problem the cell had ends right there and doesn't propagate in the organism.
10. Wei saw a special type of plastic that would melt and become a liquid when it was placed in the sun, but it would not melt when placed under a desk lamp. Why does light from the sun melt the plastic when light from the desk lamp does not? Because the plastic can take in energy from the light from the sun but not from the light from the lamp. b Because light from the sun carries heat molecules, and light from the desk lamp does not. Because light from the sun pulls energy out of the plastic, and light from the desk lamp does not. Because the sun gives off a type of light that carries erlergy, and light from the desk lamp does not.

Climax community- most stable community that takes hundreds of years to develop. The types of organisms change due to __?__.
competition
random chance
being the luckiest
Answer:
competition
Explanation:
An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).
A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.
Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.
