Detailed explanation-1: -Ammonia is the waste produced by metabolism of nitrogen-containing compounds like proteins and nucleic acids.

Detailed explanation-2: -Nitrogenous Waste in Terrestrial Animals: The Urea Cycle is the primary mechanism by which mammals convert ammonia to urea. Urea is made in the liver and excreted in urine.

Detailed explanation-3: -Animals excrete a variety of nitrogen waste products, but ammonia, urea and uric acid predominate.

Detailed explanation-4: -Answer and Explanation: There are several nitrogenous wastes that are produced by protein catabolism, but the major ones are ammonia and urea. In a healthy person, the liver makes ammonia, which is then converted to urea, which is a more non-toxic waste product than ammonia.

Detailed explanation-5: -Urea is the most common nitrogenous waste product in humans. The kidneys eliminate it from the body. Ureotelism is the process by which urea is excreted.
