Finch species living on the Galapagos Islands exhibit a variety of beak types that favor different foods. Finches that eat seeds and plant parts have beaks of the shorter, thicker variety, while finches that eat insects and other small organisms have thin, pointed beaks. 78% of the finches on an island in the Galapagos have beaks that are identical to Finch 1. What conclusion can you reach about the availability of food for the finches on this island?

Assuming that by "Finch 1" it is referring to the ones that have short, thick beaks, the answer is that there is primarily seeds and plants on the island

the correct answer is:

a population changes in response to a change in the environment.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
