Are the membranes in a dialysis machine permeable or selectively permeable?
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.
Which part of a kidney dialysis apparatus actually takes the place of the nephron?
tubing made of selectively permeable membrane
A cell membrane is like a what?
A semi-permeable membrane. It could be compared to dialysis tubing.
A membrane that allows some substances to pass through while excluding others would be called a?
semipermeable or selectively permeable.
Are artificial membranes in a dialysis machine permeable or selectively permeable?
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.
What is the basic strcture of a cell membrane?
Cell membrane is elastic and transparent. It can be impermeable, permeable, semi-permeable or selectively permeable. In humans the plasma membrane is selectively permeable that is it allows entry to certain substance.
Does the membrane of a cell is selectively permeable?
no
What is the relationship between cell membrane and selectively permeable?
Cell membranes are indeed selectively permeable.
What does a selectively permeable membrane do?
A selectively permeable membrane allows some substances through it and does not allow others.Allows certain substances to pass but not others
What is definition of selectively permeable?
The selectively permeable phospholipid bilayer (a.k.a plasma membrane) is 'selectively permeable' because it selects which molecules it allows to permeate (pass through).
Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
What is required for osmosis and dialysis?
a semi permeable membrane
