g Define nitrogen balance and describe how it is used to assess protein requirements in humans. Give examples of positive, zero (equilibrium), and negative nitrogen balance in humans.

The nitrogen balance refers to the ingested nitrogen, one gram of nitrogen is equivalent to 6.25 g approx of protein.

Nitrogen in our body must be in balance, for that a large part is eliminated in urine, in the form of urea, and the rest through sweating, breathing and in epithelial expressions.

Explanation:

The nitrogen balance if it has a positive value is because we lose less than what we ingest in the day, if its value is zero, it is because the same thing that we ingest is we lose it in the day.

Instead, the problem is usually when the value is negative, here we are talking about the organism releasing more than we ingest, therefore some systemic failure will be happening.

explanation:

on disadvantage of hydroelectric power is the cost. another disadvantage of using hydroelectric power is finding a water source powerful enough to harvest hydroelectric power.
