Sweat from apoeccrine glands is not thshould help control a person’s temperature as it cannot evaporate easily from the underarms.


What is ammonia?

Ammonia (NH3) is a colorless gas that is a compound of nitrogen and hydrogen. It has actually a solid odor that smells prefer urine or sweat.

Ammonia occurs normally in water, soil, and the air, and also is likewise discovered normally in plants, animals, and also the humale body.
