Answer 1

Answer:

01). D). Nucleic acids, proteins, carbohydrates and fats

Explanation:

Nucleic acids are the polymers of nucleotides.

Proteins are the polymers of amino acids

Carbohydrates are the polymers of monosaccharides.

Fats are the polymers of glycerols.

02). A). Monomers

A monomer is a molecule that can be bonded to other identical molecules to form a polymer.

03). D). All of the above

04). A). Denaturation

Explantion:

Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures.

05). B). Adhesion

Explanation:

Cohesion holds hydrogen bonds together to create surface tension on water. Since water is attracted to other molecules, adhesive forces pull the water toward other molecules.
