Using the diagram below, label the polar "head" groups and the nonpolar "tails" and indicate whether they are hydro -philic or -phobic a) Simple diffusion is defined as the movement of substances from an area of [HIGH / LOW] concentration to an area of [HIGH / LOW] concentration. Substances are said to go [WITH / AGAINST] the gradient. b) Give an example of ONE/1 substance that moves into/out of a cell via simple diffusion.
