10
B
20
C
32
D
45
Explanation: 

Detailed explanation-1: -The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Detailed explanation-2: -Your body needs 20 different amino acids to function correctly. Nine of these amino acids are called essential amino acids.

Detailed explanation-3: -The human body uses just 21 amino acids to make all the proteins it needs to function and grow. Because amino acids can be arranged in many different combinations, it’s possible for your body to make thousands of different kinds of proteins from just the same 21 amino acids.

Detailed explanation-4: -Humans can produce 10 of the 20 amino acids. The others must be supplied in the food. Failure to obtain enough of even 1 of the 10 essential amino acids, those that we cannot make, results in degradation of the body’s proteins-muscle and so forth-to obtain the one amino acid that is needed.

Detailed explanation-5: -The body needs 20 different amino acids to maintain good health and normal functioning. People must obtain nine of these amino acids, called the essential amino acids, through food. Good dietary sources include meat, eggs, tofu, soy, buckwheat, quinoa, and dairy.
