Explanation:

• For question 27: Proteins are made up of amino - acids which contain an amino functional group.
• For question 28: Nucleic acids (DNA and RNA) have monomers that contain a pentose sugar.
• For question 29: Phospholipids have a polar phosphate - head and non - polar fatty acid tails.

Answer:

1. C. amino
2. B. nucleic acids
3. A. has both polar and nonpolar regions
