Male peacocks have large colorful tails that they spread in a fan shape to attract females during courtship. peahens (female peacocks) are more likely to mate with males that have larger and more colorful tails. as a result, few peacocks have tails with dull coloring. mc004-1.jpg which concept is demonstrated by a decrease in dull coloring?

Natural selection

Explanation:

Natural selection can be described as the differences in the reproduction and survival strategies of individuals as a results of differences in phenotype.

In a more simple language, natural selection refers to a situation whereby organisms that have favorable trait have higher probability to reproduce. In this process, these traits are transferred to the next generation which gives the organisms the ability to adapt to their environment over a long period of time.

Related examples of natural selection are the peppered moth, the peacock large and colorful tails, and the deer mouse.

Therefore, the concept demonstrated by a decrease in dull coloring of peacock is natural selection.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
