The diagrams below show the bones in the
forelimbs of three different organisms. Differences in the bone arrangements support
the hypothesis that these organisms
(1) are members of the same species
(2) may have descended from the same ancestor
(3) have adaptations to survive in different
environments
(4) all contain the same genetic information

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.

this is a good question! i'll do some research and come back when i have the answer!
