The Bear population would increase due the the raise in the salmon population.
Hi there,
The answer to this question is
D. All of these
Changes in different temperature and acidity can change the function of a cell. Acidity and Temperatures are usually balanced for the cell function but one small change in one of them can throw off the cell of the pH levels.
Hope this is correct :)
Have a great day
Question: Does geographic distance between salamander populations increase their reproductive isolation? To answer this question, researchers studied populations of the dusky salamander (Desmognathus ochrophaeus) living on different mountain ranges in the southern Appalachian Mountains. The researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. Four mating combinations were tested for each pair of populations (A and B)—two within the same population (female A with male A and female B with male B) and two between populations (female A with male B and female B with male A). The proportion of successful matings for each mating combination was measured. For example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. Then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). The reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (AA + BB) minus the sum of the proportion of successful matings of each type between populations (AB + BA).
The table (Figure 1) provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.

What hypothesis did the researchers test in this study?
Answer:
"Reproductive isolation increases with geographic distance between dusky salamander populations"
Explanation:
The mechanisms of reproductive isolation are a assemblage of evolutionary mechanisms, behaviors and physiological procedures dangerous for speciation. They avert followers of dissimilar types from manufacturing offspring, or confirm that any offspring are germ-free. While in allopatric speciation the reproductive isolation is resolute superficially by the spatial isolation of populations, during sympatric speciation specific groups of persons create distinct mating organizations with self-like persons while distribution the similar home with the rest of the unique inhabitants.

Answer:
The correct answer is - A. Producing offspring that are genetically identical to the parents
Explanation:
Genetic variation is the difference between the population or individual on a genetic level. If there is a change in the DNA of individuals or among the population, it is genetic variation in these organisms.
There are several factors that result in genetic variation such as random mating, random fertilization, mutation, crossing over during meiosis, and many more. Producing genetically identical offspring to the parents is not a factor as there is no variation is taken place on the genetic level.
