Which macromolecules have a basic unit that is composed of phosphate, a sugar ring and one of five difirent bases Carbohydrates
Lipids
Proteins
Nuclei acids

Nucleic acids

Explanation:

Nucleic acids are the macromolecule made of a phosphate, sugar ring, and a nitrogen base.

These three components are the major parts of the nucleic acid.

Nucleic acids can differ in the type of nitrogenous bases that they have, because DNA and RNA have different bases.

However, all nucleic acids have a basic unit that is made up of a phosphate group, sugar ring, and nitrogen base.

So, the correct answer is Nucleic acids.

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)
