Research

Diffusion refers to the movement of particles from of a place of high concentration to a place of lower concentration due to natural and continual motion. It can also occur without a member, for example, in water or air. Cell survival will also depend on diffusion rates, as it is an important process to guarantee how fast a cell can obtain nutrients or rid itself pf wastes. Important factors to consider for diffusion rate include: temperature, molecular weight, "steepness" of the concentration gradient, membrane surface area, and membrane permeability.

(Saladin, 2020 p. 87-88).

Critical Thinking

During research, one fact that stood out the most was that the average water molecule moves about 2.500 km/h. However, they can only travel brief distances before crashing with another molecule and taking a new direction. (Saladin, 2020 p. 88).
