Dna, rna, and starch: what do these three important biomolecules have in common? a) they all contain at least one carboxyl group. b) the presence of at least one carbon-based sugar. c) the presence of strong hydrogen bonds between monomers. d) they all contain at least one amino group composed of a nitrogen atom. submit

The correct answer is -

B)The presence of at least one carbon-based sugar.

Explanation:

RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) are the two types of nucleic acids that are composed of nucleotide (monomer of nucleic acid).

A nucleotide has three parts, which are pentose sugar (5 carbon sugar), nitrogenous base, and phosphate group.

Starch is a complex carbohydrate as it is composed of several units of simple sugar such as glucose.

Thus, the presence of at least one carbon-based sugar is common in DNA, RNA, and Starch.

answer; i believe that the correct answer is ; males are hemizygous for the x chromosome;

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
