Answer:
It depends on the fish (I do not see any pictures) Any fish is an example of natural selection.
Explanation:
A good example would be that polar bears grew and evolved to have white fur to blend in the snow to sneak upon prey. However, their brown bear counterparts failed to do that. So due to better camouflage and hunting technique, the polar bears survived more up north.
During the lunar month, the Moon goes through all its phases. You can see the phases drawn in the image below. Just like the Earth, half of the Moon is lit by the Sun while the other half is in darkness. The phases we see result from the angle the Moon makes with the Sun as viewed from Earth.

Answer:
is common because it promotes homeostasis
Explanation:
The negative feedback loop is a mechanism wherein a change in some condition stimulates a response to counteract the changed condition and thereby, the homeostasis is restored.
For example, an increased blood glucose level above its homeostatic level stimulates the secretion of insulin hormone from the pancreas which in turn stimulates the absorption of glucose from the blood into the cells (specifically the liver and muscle cells) and thereby restores the normal blood glucose levels.
Most of the processes in the human body are regulated by negative feedback loops to maintain the homeostasis.
