Question

which of the following statements best explains how dialysis removes waste products from the blood? a dialysis does not require energy because solutes diffuse from a region of high concentration to a region of low concentration. b dialysis requires energy because solutes diffuse from a region of low concentration to a region of high concentration. c dialysis requires energy because solutes diffuse from a region of high concentration to a region of low concentration. d dialysis does not require energy because solutes diffuse from a region of low concentration to a region of high concentration.

Explanation:

Dialysis is a passive - transport process where waste products move from an area of high concentration (blood) to an area of low concentration (dialysate) through a semi - permeable membrane. This is a form of diffusion and does not require energy input.

Answer:

C. Dialysis does not require energy because solutes diffuse from a region of high concentration to a region of low concentration.
