Diffusion takes place according to concentration gradient. Is it possible for materials to move against concentration gradient gradient? If yes mention why these is required.​

Answer»

tion:The DIFFERENCE in the concentration of a substance between two areas is CALLED the concentration gradient . The bigger the difference, the STEEPER the concentration gradient and the faster the molecules of a substance will diffuse.
