Which of the following correctly pairs the macromolecule with its monomer? A. protein- monosaccharide
B. Lipids- Fatty acid
C. carbohydrate- amion acid
D. nucleic acid- amino acid

The branch of science which deals with a living being is called biology.

The correct option is B.

There are 4 types of biomolecules present in the cell, these are as follows:-

All these polymers are made up of monomers. The repetitive attachment of the monomer will join together to form a polymer.

The monomers are as follows:-

Hence, the correct option is B that is Lipids- Fatty acid.

The correct answer is : option B. lipids - fatty acid.

Explanation:

Fatty acid and glycerol are the building blocks or monomers of the lipids, lipids itself is a building block that make a cell structure and cell function. These are acts as component for cell membrane, helps in signalling and storehouse for energy.

Amino acids are monomer of protein molecule, monosaccharides for carbohydrate and nucleotide are monomer of nucleic acid.

Thus, the correct answer is : option B.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
