Explanation:

First Question:

Carbohydrates (like glucose) are the primary source of short - term energy. Proteins are for structure/enzymes, lipids for long - term energy, nucleic acids for genetic info.

Nucleic acids (DNA/RNA) contain the genetic code that is used to synthesize proteins. They don't code for lipids or carbohydrates.

Cell membranes are mainly composed of phospholipids (a type of lipid) along with proteins. Nucleic acids are in the nucleus, carbohydrates have other roles.

Answer:

D. Carbohydrates
