Answer:

Stabilizing selection

Explanation:

Stabilizing selection is the most common form of natural selection that is not easy to notice in a population as the change is less drastic.  It occurs when average or intermediate phenotypes of a trait in a population are favored, while the extreme phenotypes of that trait are not favored by the forces of natural selection.

Answer:

b. heat energy

Explanation:

Water, which is able to exist in three different states moves from one form to another. Water can move from the ocean to the atmosphere via a process called EVAPORATION.
