Question

question 24
a(n)______is made up of a 5 - carbon sugar, a phosphate group, and a nitrogenous base.
a monosaccharide
b nucleotide
c amino acid

Explanation:

A monosaccharide is a simple sugar, not composed of a phosphate group and nitrogenous base. An amino acid has an amino group, carboxyl group, etc., not the components mentioned. A nucleotide, however, is precisely made up of a 5 - carbon sugar (ribose or deoxyribose), a phosphate group, and a nitrogenous base (like adenine, thymine, etc.).

Answer:

B. nucleotide
