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".)
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.
what is a monera? Give me explanations
Answer/Explanation:
Monera is an outdated/old-fashioned classification that describes a kingdom of prokaryotic organisms. Nowadays, we split prokaryotic organisms into two kingdoms: bacteria and archaea.
Monera describes organisms that do not contain a true nucleus, including all species of bacteria, archaebacteria, and some cyanobacteria. It does not contain eukaryotic single celled organisms like fungi or protists.
Answer:
Monera is a kingdom that contains unicellular organisms with a prokaryotic cell organization, such as bacteria. They are single-celled organisms with no true nuclear membrane. The taxon Monera was first proposed as a phylum by Ernst Haeckel in 1866

The feature may interrupt the sides of a composite-cone volcano is fumaroles. Thus, option B is correct.
What is fumaroles?They are gaseous emissions from lavas in craters at more or less elevated temperatures. Its composition varies according to the temperature of the lavas, in such a way that it changes since the fumaroles appear until their extinction.
Fumaroles are gaseous emissions from lavas in craters at more or less elevated temperatures. Its composition varies according to the temperature of the lavas, in such a way that it changes since the fumaroles appear until their extinction. Water flows in the form of steam continuously through the cracks of a volcano or volcanic surface because its temperature exceeds 100 °C.

You run 30 PCR cycles using primers that amplify a tandem repeat (let's call it D3T40) on Chromosome 3. Choose all of the statements below that are correct. A. The number of repeats at the D3T40 locus will vary among individuals.B. The size of an individual's amplicons is determined by the number of repeats at the D3T40 locus.C. The primers will anneal to the sequences that flank the D3T40 locus.D. Taq polymerase will amplify the entire length of Chromosome 3.E. About 30 amplicons will be produced at the end of 30 cycles of PCR.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.H. The primers used to amplify D3T40 could be used to amplify another locus like the D1S80 locus on Chromosome 1.
Answer:
A b c f and g are true
Explanation:
A is true because when we have different individuals we can observe dna polymorphism.
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.

PCR.
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.

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
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.
