Studying the decay of radioactive isotopes in dead organisms helps scientists to identify fossilized remains. The ratio of C-12 to 0—14 in the atmosphere is 1 x 1012. The table shows this ratio inside the body of three organisms. C121C14 Ratio
Organism ClZIC14 Ratio E s x 1012 F 1 x 1012 G 4 x 1012 What can most likely be concluded from the above information? 0 Only Organism F is alive, and Organism G died before Organism E. 0 Only Organism F is alive, and Organism E died before Organism G. 0 Only Organism E is alive, and Organism G died before Organism F. 0 Only Organism E is alive, and Organism F died before Organism G

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.
