The model shows a substance crossing a cell membrane. Solute particle Cell membrane
Which of the following describes the process?

a.
The model shows the process of active transport because the solute particles are
moving from an area of low concentration to an area of high concentration.

b.
The model shows the process of bulk transport because the solute particles are
moving from an area of low concentration to an area of high concentration.

C.
The model shows the process of diffusion because solute particles are moving from
an area of high concentration to an area of low concentration.

d.
The model shows the process of osmosis because the solute particles are moving
from an area of high concentration to an area of low concentration.
