question 14 of 22
which of the following macromolecules surround and protect internal organs?
a. lipids
b. carbohydrates
c. vitamins
d. nucleic acids

Explanation:

Lipids, specifically adipose tissue (a type of fat), can surround and protect internal organs. Carbohydrates are mainly for energy storage (like glycogen) or structural support in plants (cellulose). Vitamins are essential micronutrients but not macromolecules that surround organs. Nucleic acids (DNA and RNA) are involved in genetic information storage and transfer.

A. Lipids
