Answer: A (colored feathers.)
Explanation: There are many birds with colors that are variously different on the Galapagos.
So, Darwin carefully observed the finches of the Galapagos island. What he noticed was that they were similar to the mainland finches, but each island finch has different colored feathers.

Nucleotides are organic molecules consisting of a nucleoside and a phosphate. They serve as monomeric units of the nucleic acid polymers deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth.
Explanation:
Peregrine falcons have a wide diet, including many types of smaller birds. These birds eat bugs like grasshoppers. So, if the grasshopper population decreases, then the birds who are a food source to peregrine falcons will also have a lower population. This means that there is a lesser amount of food for the peregrine falcons to eat, so their population will decrease as well.
