Dna is different from rna in that
a. rna is made up five bases, whereas dna is made up of four.
b. in general, rna molecules are longer than dna molecules.
c. rna contains an additional oxygen atom on the ribose sugar.
d. rna cannot exist as a double helix. all of these statements are true.

RNA contains an additional oxygen atom on the ribose sugar. (Ans. C)

Explanation:

RNA contains a sugar which is known as ribose, and which contains an extra group of hydroxyl (OH-) while DNA contains deoxyribose sugar.

RNA contains four nitrogenous bases cytosine, adenine, guanine, and uracil, while DNA contains cytosine, adenine, guanine, and thymine.

Double helix means two stranded structure like DNA, while RNA is single stranded.

DNA molecule is much longer polymer than RNA molecule.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
