Question

explain why some desert animals excrete urea rather than ammonium

Answer 1

Answer:

Excess nitrogen is excreted from the body. Nitrogenous wastes tend to form toxic ammonia, which raises the pH of body fluids. ... In contrast, mammals (including humans) produce urea from ammonia; however, they also form some uric acid during the breakdown of nucleic acids.✌️✌️✌️
