Using the scenario, identify each of the parts listed below: Mr. Lehman wanted to know whether or not his students would do better on a quiz if he promised them candy. He guessed that the more candy that his students were promised, the better they would do on the quiz. He had all of his classes participate in the experiment. There were two groups in all. The first group was not promised any candy if they did well on the quiz. The second group was promised a candy bar if they did well on the quiz. Group #1 got an average of 70% on the quiz. Group #2 got an average of 90% on the quiz. Mr. Lehman then decided that if students were promised a candy bar, the better they did on quizzes. He then repeated the experiment with different students.

i think it is dna, i'm not totally sure but i think it might be.

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.
