Antidiuretic hormone (ADH) is a hormone secreted by the hypothalamus which plays a significant role in regulating fluid and electrolyte balance in the body. This hormone directly affects the blood volume, the level of water in the body, the concentration ...
Water molecules move from the region outside the cell, where the concentration of particles is relatively low, to the inside of the cell, where there is a high particle concentration. In the same way as diffusion, this movement reduces the concentration gradient between the two areas. It can...
How does this difference in amount of a dissolved substance provide energy for the movement of molecules? Here is a basic explanation with images.

concentration; in the US, 80 proof is precisely equal to 40 volume-percent. The term, however, was first defined in the UK as 7/4, and not 1/2, the percent concentration of alcohol. This is because the desirability of the spirits were proven by the ignition of an admixture with ...
