Amino acid-based hormones use a second messenger, cyclic amp, but steroid hormones

trigger a response by their buildup along the cell membranes, stopping key materials from entering the cell

must use atp to enter the cell, releasing adp into the cytoplasm, which then becomes cyclic amp

complex inside the nucleus with a receptor and dna to initiate protein synthesis

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.
