II. Nucleic acids
III. Proteins
IV. Lipids
a. I only
b. I and II only
c. I and IV only d. I, III and IV
2. Select correct information about the given diagrams:

Answer 1

Answer:

op 3

Explanation:

polysaccharides do not contain nitrogen

nucleic acid contain nitrogen in bases

protein contains nitrogen in amino acid

lipids lack nitrogen

Answer 2

Polysaccharides and Lipids do not contain nitrogen

• Polysaccharides are a type of biomolecules belonging to the class of carbohydrates that is composed of monomers that are further made up of C, H, and O.
• Nucleic acids are a type of biomolecules that contains heterocyclic ring structures which are made up of nitrogenous bases that further contain nitrogen.
• Proteins are a type of biomolecules that is composed of monomers of amino acids that contains a nitrogen-containing group called an amino group (NH₃).
• Lipids are a type of biomolecules that are further made up of fatty acids which contain hydrocarbon and a carboxylic acid group.

Thus, Non-nitrogenous biomolecules among the following are (Option C) I and IV only.
