Urea is best described as which of the following?

Explanation:
Urea is the major nitrogenous waste excreted in urine. In animals, nitrogen from protein breakdown is converted in the liver into urea through the urea cycle to detoxify ammonia. This urea travels to the kidneys and is excreted in urine, making it the primary nitrogenous waste produced. It is not a pesticide, a plant growth regulator, or a soil conditioner—the former targets pests, the latter two influence plant growth or soil properties.
