Sexual reproduction appears to be absent in bdelloid rotifers. which of these, if found in this group, would bring into question the idea that they reproduce only asexually?

 Sexual reproduction in humans allows a haploid sperm cell to fertilize a haploid egg cell. It also appears to be absent in bdelloid rotifers, cells in which meiosis occurs would bring into question the idea that they reproduce only asexually. Meiosis does not produce cells genetically identical to the parent cell.

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.
