Answer 1

Q.10 It is given here that 15-20% weight of human body is occupied with body fat.

Thin person = 8% body fat

Overweight person = 38% body fat

And we know that the body weight of water in a regular person is 45-60%.

total percentage of nucleic acid, carbohydrate and protein is 20%.

Thus thin body contains approximately 27% of body water and that of fat person is 17%.

Q.11 The molecule presented above is known as Protein which contains a peptide bond formed by the condensation of amine group of one amino acid and carboxylic group of the other. Protein are one of the building blocks of body and serves as a body fuel.

The bond shown by arrow (A) is the Peptide bond.
