C. Provide one possible explanation for the change in bird numbers and beak characteristics.
AlladinOne [14]

Answer:

Evolution

Explanation:

If there is an environmental stressor, then animals will evolve to overcome it.

Birds may begin producing more or fewer offspring depending on how much food is available. If there is more food available, birds will have more offspring. If there is less food available, birds will produce fewer offspring.

Beak characteristics change depending on food options, mating rituals, or environment. A bird will need a narrow beak for most bugs, but it will need a wider and stronger beak for nuts and seeds. A bird's beak may also be used to help interact with its environment. For example, a woodpecker has a strong narrow beak to help it break into tree bark to eat.

A population of wolves migrates north in search of food. as the wolves travel, they enter a region that has long, snowy winters.
Nookie1986 [14]
This is the case of selective pressure of environmental factors like snow, due to which favored the expression of the allele that formed white coat phenotype. This is not a Hardy-Weinberg principle, in which no selective pressure is applied. The relative frequencies of the alleles change in the gene pool, due to selective pressure, and the expressed alleles are often significant for survival in those conditions.
