The process of adsorption and subsequent ... of concentrations a mechanism fundamentally different from diffusion is at work: the liquid rearranges in a much slower, activated process that takes ...

particles will spread themselves evenly throughout a liquid or a gas. Diffusion is an essential process in cells. They need glucose and oxygen for respiration, which move into them by diffusion.

That's because of a process called diffusion. Diffusion refers to the overall movement of particles from areas of high concentration to areas of low concentration. In living things, diffusion ...
