Question

which best summarizes the peppered moths in england after the industrial revolution?
a. the phenotype frequency changed.
b. a new mutation allowed moths to survive.
c. moths learned to adapt to their environment.
d. the light moths had an advantage.

Explanation:

Before the Industrial Revolution, light - colored peppered moths were more common as they could blend in with the light - colored tree bark. After the Industrial Revolution, pollution darkened the tree bark. Dark - colored moths then had a survival advantage as they could better camouflage. This led to a change in the frequency of the dark and light phenotypes in the moth population. Option B is incorrect because the mutation for dark color already existed before the Industrial Revolution. Option C is wrong as it was natural selection (not learning) that caused the change. Option D is incorrect because after the Industrial Revolution, the dark moths had an advantage, not the light ones.

Answer:

A. The phenotype frequency changed.
