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. simple diffusion across a semi - permeable membrane. movement of water into the blood from the dialysis solution. active transport across a semi - permeable membrane. facilitated diffusion across a semi - permeable membrane.

Explanation:

Dialysis cleans blood wastes through simple diffusion across a semi - permeable membrane. In this process, waste substances move from an area of higher concentration in the blood to an area of lower concentration in the dialysis solution without the need for energy (unlike active transport) and without the help of carrier proteins (unlike facilitated diffusion). Movement of water is not the main process for cleansing wastes, and glucose transport is not the key mechanism for waste - removal in dialysis.

Answer:

B. simple diffusion across a semi - permeable membrane.
