Diffusion ______. select one:
a. proceeds until equilibrium is reached
b. occurs when particles spread from areas where they are less concentrated to areas where they are more concentrated
c. is driven by an input of cellular energy
d. requires an input of cellular energy
e. is the result of the potential energy of atoms

Respuesta :

I believe the correct answer is A. Diffusion happens continually until equilibrium is attained. It moves from a higher concentration to a lower concentration. The driving force of such process is the concentration gradient between two systems. In order to be in equilibrium, the concentration at any point of a mixture should be equal.
