The recommended daily amount of drinking water for humans varies.

Macrophytes perform many ecosystem functions in aquatic ecosystems and provide services to human society. One of the important functions performed by macrophyte is uptake of dissolved nutrients including nitrogen and phosphorus. [39] Macrophytes are widely used in constructed wetlands around the world to remove excess N and P from polluted ...
Flu A and flu B are the most common strains of the flu that circulate in humans. The U.S. is currently in the middle of flu season, with a high number of cases reported across the country.
The human body and even its individual body fluids may be conceptually divided into various fluid compartments, which, although not literally anatomic compartments, do represent a real division in terms of how portions of the body's water, solutes, and suspended elements are segregated. The two main fluid compartments are the intracellular and ...
