Question

Quizplus · Accepted Answer

The movement of oxygen from an area of high concentration to an area of low concentration is an example of diffusion, which is the passive movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the diffusion of water molecules across a selectively permeable membrane, while active transport and facilitated transport require energy and specialized transport proteins. Filtration involves the movement of substances through a filter due to pressure differences.
