What happened to the color of moths over time?

At long last it was tracked down that the shading was hereditary. Moths passed their shading to the future. Eggs from light moths formed into light moths and dim moth eggs went to dull grown-ups. The dim shading was brought about by a change in the DNA of a solitary moth, and the transformed quality had been passed to all its posterity.

Explanation:

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.
