Describe how water
Alla [95]

Explanation:

Epipelagic zone, the topmost at the surface of the oceans receives most of the sunlight and most penetrating light rays diffuse in this layer. The temperatures at this zone, therefore, is warmer than zones below. This zone has lowest water pressure becaue there is little water column above it.

The deeper you get into the water the penetration of sunlight decreases. This is because the rays are greatly diffused even before they get to the deepest zones. The abyssalpelagic zone virtually receives no sunlight because the rays cannot get to this zone. This zone is, therefore, pitch dark and also the coldest. The deeper you get into the ocean the higher the water pressure due to the weight of the able water column. The water pressure is, therefore, highest in the  abyssalpelagic zone.

vaieri [72.5K]
Homeostasis is the natural state of equilibrium; the body attempts to maintain this equilibrium by constantly reacting to external forces that attempt to disrupt the fine balance. It involves the maintenance of the internal environment constant, this involves conditions such as blood sugar, body temperature, among other factors that enhance functions in the body. Through homeostasis organisms tend to resist changes in order to maintain a stable, and a constant internal environment.
