Question

in dialysis, the cleansing wastes from the blood is achieved by
multiple choice
active transport of glucose from the blood to the dialysis solution.
facilitated diffusion across a semi - permeable membrane.
movement of water into the blood from the dialysis solution.
simple diffusion across a semi - permeable membrane.
active transport across a semi - permeable membrane.

Explanation:

Dialysis uses a semi - permeable membrane. Wastes move from an area of higher concentration in the blood to an area of lower concentration in the dialysis solution by simple diffusion. There is no energy - requiring active transport or facilitated diffusion of wastes in the typical process of cleansing wastes from the blood in dialysis. Movement of water into the blood is not the main way of cleansing wastes.

Answer:

simple diffusion across a semi - permeable membrane.
