Answer:
B. Evolution
Explanation:
The change in allele frequencies from mostly light wings to dark wings has been commonly studied in evolution. It's a great example of natural selection favoring the more fit phenotype, in this case the dark that can blend in better with darker trees and darker, smoggy environment.
- Why not competition: This doesn't have to do with limited resources.
- Why not acquired: Lamarck's theory of acquired traits is defunct!! Don't fall for it!!
- Why not overpopulation: This was not hinted at in the question.

<span>Well water draws from the sources of water beneath the Earth's surface. This type of water supply is known as "groundwater."
</span><span>Groundwater includes water that flows naturally from below the Earth's surface to the surface by way of springs. Some springs run entirely underground and do not break through the surface. Groundwater also includes water that is contained in a variety of porous materials that lie beneath the Earth's surface, such as silt, gravel, clay and sand. Water collects below ground in these porous materials into structures called aquifers. Generally speaking, well water collects into the well from these water-bearing structures. Wells are situated in the Earth to access the aquifer at a depth well below the surface.</span>
Answer:
Evaporation
Explanation:
The panting responses observed in overheated birds and mammals dissipate excess heat by evaporation
