You are studying three populations of an endangered species of toad that used to be common in the California central valley. Global warming has caused this species to retreat to higher elevations in recent decades where it stays cooler; the toad used to be found throughout the valley, but is now restricted to the tops of three mountains. Historical records indicate that there used to be hundreds of thousands of toads in the central valley, but sampling the mountaintops reveals that the toad population on each is now limited to a few hundred individuals. You survey allozyme diversity at one locus on each of the three mountaintops and find that each population is fixed for a different allele of the ribbit gene: mountain #1 is fixed for the A1 allele, mountain #2 for the A2 allele, and mountain #3 for the A3 allele. The average number of baby toads born in each population is the same, and the environment on each mountaintop is very similar, as far as your data show.
Explain why each population is fixed for a different allele.
Sentence 1: Describe the variability that was initially present in each of the populations.Sentence 2: State which individuals had the highest fitness in a given population, or why fitness is not an issue if that is your conclusion.Sentence 3: Explain what evolutionary force acted on the population(s), and why and how it acted.Sentence 4: Describe how the populations evolved in response to their changing environment. Be as specific as you can (e.g., say "increased" or "decreased", rather than just "changed".)

Answers

Answer:

Explanation:

The allele are fixed because there is no variation that exist in the population and the allele are almost completely the same hence no new combination of gene the same Allele will continue to reoccur

Variability exist because of random mating that occurs in the population initially when the toad filled up the entire central valley

Random mating ensures fitness in the initial population

Genetic drift acted upon the population drifting away allele that are very few in population or that occur less in the population and perpetuating alleles that frequently occur leading to a fixed allele.

There was a decrease in the population as a result of the change in the environment.

B is true because the size of the amplicon is determined by the treat count of D3T40 locus

C. Is true because polymorphic sequence are actually flanked by primers

D is false

E is false

G is true

F is false

The statements below that are correct include:

A. The number of repeats at the D3T40 locus will vary among individuals.

F. You can determine the size of an individuals D3T40 amplicons using gel electrophoresis.

G. The size of the amplicons produced will vary among individuals.

It should be noted that DNA polymorphism can be observed among different individuals. Therefore, the number of repeats at the D3T40 locus will vary among individuals.

Also, the amplicon size depends on the number of repeats. Hence, the size of an individual's amplicons is determined by the number of repeats at the D3T40 locus.

what is ecosystem

Answer:

[tex] \boxed{ \text{below \: in \: bold}}[/tex]

Explanation:

[tex] \huge{ \underline{{ \text{Ecosystem}}}}[/tex]

No living beings can survive alone. There always exists a close relationship between living and non - living things. The environment of the earth consists of physical and biological factors. The physical and biological factors together constitute an ecosystem. The ecosystem may be natural or artificial , temporary or permanent. Thus, an ecosystem is an ecological unit which consists of both biotic ( living ) and abiotic ( non - living ) factors of the environment. The organisms and the environment are inseparably interrelated and interactive in their nature. A.G. Tansley ( 1935 ) , a British ecologist used the term ecosystem first.

Question:

☞ What is ecosystem?

Answer:

Ecosystem is a community of living organisms interacting with each other and their non-living environment. It means that it is an area where organisms interact with one another as well as with non-living parts of the environment. An ecosystem can be huge, such as a large forest or lake, or it can be small, such as a puddle of water or a rotting log. Hence, All things that interact in an environment make up an ecosystem.

An ecosystem has two parts:

Biotope - it includes all of the non living things in an ecosystem.

Biocoenosis - It includes all the living things in an ecosystem.

The images below show the same cell, before and after reaching equilibrium. Which statement best describes what happened as the volume of the cell increased

Answers

The missing part of the question and group of options is attached as an image.

Answer:

The correct answer is - D - The number of solvent particles outside the cell decreased.

Explanation:

As the solution reached equilibrium the concentration of the solute is equal inside the cell and outside the cell, so the number of particles of the solvent must increase inside and decrease outside of the cell.

The cell volume increased due to the flow of the solvent from outside to the inside of the cell this type of diffusion of solvent is known as osmosis which leads to the swollen or bigger cell.

Answer:

The number of solvent particles outside the cell decreased.
