Mammals excrete nitrogen wastes in which of the following?

Question

Quizplus · Accepted Answer

Mammals excrete nitrogen wastes in the form of urea, which is the least toxic of the three major nitrogenous wastes. Ammonia is highly toxic and requires a lot of energy to convert to a less toxic form. Uric acid is solid and requires little water to excrete, making it useful for animals living in arid environments, but it is more energetically expensive to produce than urea. Nucleotides and allatonin are not major nitrogenous wastes.
