What else can I help you with?
A membrane that allows only certain substances to pass through is a?
A permeable membrane
Why can't ions pass through the cell membrane?
Ions cannot pass through the cell membrane because the membrane is selectively permeable, meaning it only allows certain substances to pass through. Ions have an electric charge that makes it difficult for them to pass through the hydrophobic interior of the membrane.
What only allows certain substances in and out of a cell?
The permeability of the cell membrane controls which substances may pass in or out of the cell.
What allows some materials to pass through it but keeps other materials out?
A selectively permeable membrane allows only certain molecules or substances to pass through, based on their size, charge, or other properties. This membrane acts as a barrier that can control the passage of specific substances while blocking others.
How does the composition of the cell membrane help regulate the movement of substances into and out of the cell?
The cell membrane is composed of a phospholipid bilayer that is selectively permeable, allowing only certain substances to pass through. The presence of proteins, such as channels and carriers, also help regulate the movement of specific molecules across the membrane. Additionally, the membrane's fluidity and structure play a role in facilitating or hindering the diffusion of substances.
A membrane that allows only certain substances to pass through is a?
A permeable membrane
Is plasma membrane premeable?
The plasma membrane is selectively permeable; it allows some substances to pass through but prevents the passage of other substances
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 characteristics of cell membrane allows for some substances to pass through but not others?

What do you call a membrane that only allows certain substances to pass through it?
semipermeable membrane
What layer is permeable?
A fully permeable layer is a layer that allows all substances to pass through. A partially permeable membrane is a membrane that only allows some substances to infiltrate.
What property in the cell membrane that allows only some substances in?
Semi-permeable. Permeable means things can pass through, so semi-permeable means only some things can pass through.

Does a permeable membrane will let substances pass through it?
Yes, a permeable membrane allows certain substances to pass through while blocking others based on their size and chemical properties. It enables the selective transport of molecules, ions, or particles across a barrier, such as in biological systems or in water filtration processes.
