Question

molecules will move through a selectively permeable membrane until there is a balanced concentration on both sides of the membrane. which of the following statements best describes the cell transport shown in the picture above? a active transport because particles are moving with their concentration gradient until they are evenly dispersed. b passive transport because particles are moving against their concentration gradient until they are evenly dispersed. c active transport because particles are moving against their concentration gradient until they are evenly dispersed. d passive transport because particles are moving with their concentration gradient until they are evenly dispersed.

Explanation:

In the image, molecules move from an area of high - concentration to an area of low - concentration until equilibrium is reached. This is passive transport as it occurs with the concentration gradient without the use of energy. Active transport moves against the concentration gradient and requires energy.

Answer:

D. Passive transport because particles are moving with their concentration gradient until they are evenly dispersed.
