When particles move from area of high concentration to area of low concentration, this is ____
|
|
osmosis
|
|
|
diffusion
|
|
|
concentration gradient
|
Explanation:
Detailed explanation-1: -In passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower concentration, until they are evenly spaced.
Detailed explanation-2: -Diffusion is defined as the net movement of molecules from an area of greater concentration to an area of lesser concentration. The molecules in a gas, a liquid or a solid are in constant motion due to their kinetic energy.
Detailed explanation-3: -In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached.
