Vedclass · Answer

(C) Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration.$(1)$ Molecules move in a random fashion due to kinetic energy,which is correct.$(2)$ The rate of diffusion is directly proportional to the concentration gradient,which is correct.$(3)$ Diffusion is a slow process,but it is a physical process and does not depend on a 'living system'. Therefore,this statement is incorrect.$(4)$ Diffusion is a passive process because it does not require the expenditure of energy $(ATP)$. Therefore,this statement is correct.Thus,statements $(1), (2),$ and $(4)$ are correct.

Choose the correct sentences for diffusion:
$(1)$ In diffusion,molecules move in a random fashion.
$(2)$ Diffusion rates are affected by the gradient of concentration.
$(3)$ Diffusion is a slow process and is dependent on a 'living system'.
$(4)$ Movement by diffusion is passive.
