He or she is said to be in a positive
nitrogen balance state.
Nitrogen balance is the
traditional method of determining dietary protein requirements. Determining
dietary protein requirements using nitrogen balance requires that all nitrogen
inputs and losses are carefully collected, to ensure that all nitrogen exchange
is accounted for. Positive nitrogen balance is associated with periods of
growth, hypothyroidism, tissue repair, and pregnancy. This means that the
intake of nitrogen into the body is greater than the loss of nitrogen from the
body, so there is an increase in the total body pool of protein.
Well for both of them to survive they need oxygen, food, water amino acids, and a way to leave waste, but that depends on the type of cell
Atomic number=protons=neutrons or, A-P-E. So, an element like this doesn't exist because protons and electrons have the same number.
