Explanation:
Detailed explanation-1: -The right amount of protein is important in our diets, for growth and repair. Protein is present in the blood; healthy kidneys should only filter tiny (trace) amounts into the urine as most protein molecules are too large for the filters (glomeruli). It is not usual to lose protein in the urine.
Detailed explanation-2: -The only substance that would be found in the urine of a normal individual would be urea. Urea is the molecule through which nitrogenous wastes are eliminated in the body.
