Diffusion ________.
A)is the result of the potential energy of atoms
B)requires an input of cellular energy
C)occurs when particles spread from areas where they are less concentrated to areas where they are more concentrated
D)proceeds until equilibrium is reached

Question

Quizplus · Accepted Answer

Diffusion proceeds until equilibrium is reached, meaning there is an equal distribution of particles throughout the space they occupy. Diffusion does not require an input of cellular energy (choice B) but is the result of the random movement of atoms or molecules due to thermal energy (choice A). Diffusion also occurs from areas of high concentration to areas of low concentration, not the other way around (eliminating choice C).
