Question

1. how do \essential\ amino acids differ from other amino acids? the human body only needs essential amino acids. the human body does not need essential amino acids. the human body can make essential amino acids. the human body cannot make essential amino acids.

Explanation:

Essential amino acids are defined by the body's inability to synthesize them, so they must be obtained from dietary sources. The other options are incorrect: the body needs all amino acids (non-essential ones are made internally, essential ones come from food), so the first two options are wrong, and the third option directly contradicts the definition of essential amino acids.

Answer:

The human body cannot make essential amino acids.
