Artificial membranes in a dialysis machine are selectively permeable because it doesn't all cells to go through it. It doesn't allow blood cells to fit through the dialysis but it allows waste and bacteria to pass.
a dialysis membrane is selectively permeable, it is used in experiments to simulate cellular membranes, and it is permeable to water but not to sucrose.
The membranes in a dialysis machine are selectively permeable, meaning they allow certain substances to pass through while blocking others. This selectivity allows toxins and waste products to be removed from the blood while retaining essential substances.
The dialysis membrane is selectively permeable because it doesn't allow all cells to go through it. Think of it as a kidney. When blood is sent to the kidney, the blood cells cannot fit through the dialysis inside the kidney, but the waste and bacteria in the cells do. So, The dialysis membrane is selectively permeable.

Semipermeable membranes. These membranes allow certain substances to pass through while blocking others based on size, charge, or other properties. Examples include cell membranes and dialysis membranes.
Membranes that allow passage in and out are called permeable.Membranes that only allow "some" substances to pass through aresemipermeable or selectively permeable.
Dialysis tubing can model a selectively permeable membrane by allowing certain small molecules and ions to pass through while restricting larger molecules. When filled with a solution and submerged in another solution, the tubing will permit the diffusion of substances like water, glucose, and ions based on concentration gradients. This setup effectively demonstrates principles of osmosis and diffusion, illustrating how cells selectively allow materials in and out. By observing changes in mass or concentration, one can visualize the behavior of a selectively permeable membrane in biological systems.
are often used in processes like reverse osmosis and dialysis. They are able to selectively filter out molecules based on size, charge, or other properties, enabling the separation of substances in a solution.
A selectively permeable cell membrane allows certain molecules or ions to pass through it by means of active or passive transport. The most common example is the phospholipid bilayer cell membrane that surrounds all of our body cells. The inner membranes of an egg are also selectively permeable membranes.
A semi-permeable membrane. It could be compared to dialysis tubing.
