Question

Human beings accumulate ________ before excreting nitrogenous waste.

Answer 1

Answer:

urea

Explanation:

Excreta is the biological name used for nitrogenous residues produced by metabolism and should be eliminated in order to allow a state of internal equilibrium (homeostasis) of the organism, being the types of excreta in different groups of animals. These groups are divided between animals that accumulate ammonia, urea or uric acid prior to the release of nitrogen residues.

The human being is a ureotelic animal, that is, an animal that accumulates urea before excreting nitrogen waste.

Urea is a water-soluble substance, but less toxic than ammonia. Synthesized in the vertebrate liver from the reaction of ammonia and carbon dioxide, it represents an adaptive strategy of certain land animals: annelids, cartilage fish, amphibians, and mammals.
