Question

think about your prediction and data you recorded. what can you conclude from your data? a. the concentration gradient does not have an effect on the rate of diffusion. b. an increase in the concentration gradient will cause the rate of diffusion to decrease. c. an increase in the concentration gradient will cause the rate of diffusion to increase.

Explanation:

In the context of diffusion (a concept in Biology, part of Natural Science), the concentration gradient is a key factor. A concentration gradient is the difference in solute concentration between two areas. Diffusion is the movement of particles from an area of high concentration to low concentration. As the concentration gradient (the difference) increases, there is a steeper "driving force" for particles to move, so the rate of diffusion increases. Option A is incorrect because the concentration gradient does affect diffusion rate. Option B is incorrect as an increased gradient should increase, not decrease, the diffusion rate.

Answer:

C. An increase in the concentration gradient will cause the rate of diffusion to increase.
