"Results and survival and reproduction of organisms best suited for their current environment."

Explanation: Passive transport doesn't require energy (ATP), active transport does require energy.
Passive transport moves molecules WITH the concentration gradient (high to low), while active transport moves molecules AGAINST the concentration gradient (Low to High).
The skin color of fish is used to demystify human skin pigmentation. As revealed by studies, a fish skin color is influenced by both genetics and the environment. For example, the skin pigmentation of fish exposed to a more saline environment and fed saltier food is different compared to fish exposed to a lower concentration of salt. Based on years of studying fish skin color, it can be deduced that the variety of human skin pigment is also influenced by genetics plus the environment.
