Question

level 2 q1 what are the building blocks of proteins? a. nucleotides b. monosaccharides c. fatty acids d. amino acids level 2 q2 which of the following is not a type of lipid? a. fats b. steroids c. sugar d. waxes level 2 q3 identify the following carbohydrate: a. monosaccharide b. disaccharide c. polysaccharide d. none of the above level 2 q4 what type of nucleic acid is composed of only one strand of nucleotides? a. rna b. dna c. fat d. sugar

Explanation:

• Q1: Proteins are polymers made up of amino - acid monomers. Nucleotides are building blocks of nucleic acids, monosaccharides of carbohydrates, and fatty acids are part of lipids.
• Q2: Fats, steroids, and waxes are types of lipids. Sugar is a carbohydrate.
• Q3: The structure shown is a disaccharide as it is composed of two monosaccharide units joined by a glycosidic bond.
• Q4: RNA is a single - stranded nucleic acid, while DNA is double - stranded. Fat is a lipid and sugar is a carbohydrate.

Answer:

Q1. D. Amino acids
Q2. C. Sugar
Q3. B. Disaccharide
Q4. A. RNA
