Question

during the time that the particles are diffusing into the cell
multiple choice
the rate of the diffusion begins slowly, but eventually accelerates.
the rate of this diffusion remains constant.
the concentration of particles on the outside of the cell decreases.
a point is eventually reached where equal numbers are passing into and out of the cell.
the concentration of particles on the outside of the cell increases.

Explanation:

Diffusion is the movement of particles from an area of high - concentration to an area of low - concentration. As particles diffuse into the cell, the concentration of particles outside the cell decreases because they are moving into the cell. Eventually, equilibrium is reached where the movement of particles into and out of the cell is equal.

Answer:

C. the concentration of particles on the outside of the cell decreases; D. a point is eventually reached where equal numbers are passing into and out of the cell
