What else can I help you with?
What is the term used for a layer that allows only certain molecules to pass through the cell membrane?
permiable
What does it mean if a cell membrane is selectively permiable?
The cell membrane only allows certain molecules through.
Why doesn't powder charcoal filter through a membrane?
Powdered charcoal particles are too large to pass through the pores of a membrane due to their size. The membrane acts as a barrier that only allows smaller molecules or particles to pass through, thus retaining the charcoal particles on one side of the membrane.
What cell part allows only certain substances to difuse into and out of the cell?
The cell's membrane allows only certain substances to diffuse in and out of the cell.
What roles do membrane proteins play in making the cell membrane selectively premable?
The proteinshave certain 'identifiers' attached to them, which only allow certain particles through, making it selectively permeable.
What structure allows only certain things?
A filter or a gatekeeper can be a structure that allows only certain things to pass through. These structures help control and regulate what is permitted to enter or proceed.
