B) active transport
C) pressure gradient
D) osmosis

Question

Quizplus · Accepted Answer

Diffusion is the passive movement of gas molecules from an area of high concentration (partial pressure) to an area of lower concentration (partial pressure) until equilibrium is reached. Active transport, on the other hand, requires the use of energy to move molecules against their concentration gradient. Pressure gradient refers to the change in pressure over a distance, while osmosis specifically refers to the movement of water molecules across a semipermeable membrane.
