The nine essentialamino acids are

A)NOT FOUND IN FOODS
B)NOT MADE BY THE BODY
C)ALL PRESENT IN INCOMPLETE PROTEIN
D)MADE BY THE BODY

not made by the body, so they must come from foods.

The correct answer is D) made by the body.

Amino acids are the building blocks of proteins, and there are 20 different types of amino acids that can be used to build proteins in the human body. Out of these 20, nine amino acids are classified as essential amino acids, meaning that the body cannot produce them and they must be obtained from the diet.

To determine this answer, one can refer to a reliable source such as a biology textbook, nutrition resource, or consult a knowledgeable expert in the field of human nutrition. These sources will state that essential amino acids cannot be synthesized by the body and must be obtained from dietary sources.

It is important to note that while the body cannot produce essential amino acids, they are commonly found in many foods, particularly in protein-rich sources such as meat, poultry, fish, dairy products, legumes, and certain grains.
