What can i put for this))List 3 examples of a selectively permeable material or item. Explain where it is found or used and why a selectively permeable material is needed.?

Three examples of selectively permeable materials include cell membranes, dialysis tubing, and certain types of filters. Cell membranes are found in all living cells and regulate the movement of substances in and out, maintaining homeostasis. Dialysis tubing is used in medical treatments to separate waste from blood while allowing essential substances to pass, ensuring proper filtration. Filters, such as those in water purification systems, selectively allow clean water to pass while trapping contaminants, ensuring safe drinking water.
