Membranes that allow only certain substances to pass through are called semipermeable and?
selectively-permeable membrane and the process of this type of diffusion is called fascilitated diffusion
What is a membrane that allows some substances to pass through but excludes others?
A membrane that lets some substances pass through but not others is known as a semipermeable membrane. Other terms that describe this type of membrane are: selectively permeable, partially permeable, or differentially permeable.
Could the skin be a semipermeable membrane?
no skin couldn't be a semipermeable membrane because it doesn't allow any substances to pass through it...
The neuron's cell membrane permits some substances to pass through but not others this is because the membrane is?
One of the characteristics of a cell membrane is that it is semi-permeable. As such, it is able to limit what can get into and out of the cell.
What types of membrane allow solvent molecules to pass through but do not allow solute molecules to pass through?
A membrane that does not allow substances through is impermeable. One that allows some substances, but not others, is semipermeable or selectively permeable.
Membranes that allow only certain substances to pass through are called semipermeable and?
selectively-permeable membrane and the process of this type of diffusion is called fascilitated diffusion
What membranes are there in osmosis?
Semipermeable membranes are used in osmosis. Semipermeable membranes let some molecules pass through them but not others, so they are partially or semi permeable. For example, the membrane may let smaller size molecules pass though but block larger molecules sort of like a sifter. Thus the two molecular substances can be separated.

What is the name given to membranes that only allow certain materials to pass through them?
"semipermeable"

Which molecules help control movement of substances through cell membranes?
proteins help control movement of substances through cell membranes.

Semi permeable membranes.
What is meant by semipermealable?
Semipermeable is a term used to describe a membrane or material that only allows certain molecules particles or ions to pass through. This type of membrane is selectively permeable meaning that it will allow the passage of some materials while blocking others. Examples of semipermeable membranes include cell walls some plastics and biological membranes. The permeability of a semipermeable membrane is determined by its structure composition and size of the particles which it allows to pass through. The size of the particles is a key factor as smaller molecules are able to pass through more easily than larger ones. The composition and structure of the membrane also determine the type of molecules that can pass through it. Semipermeable membranes can be used in many different applications including water filtration food production and medical treatments. In water filtration semipermeable membranes are used to separate different types of molecules based on size and charge. In food production semipermeable membranes can be used to separate different components of a food such as fats and proteins. In medical treatments semipermeable membranes are used to deliver drugs and other treatments to specific parts of the body.
What is the cell membrane which means that some substances can pass through it while others can't?
Semipermeable membrane.
What substances that can pass through call membranes by diffusion include?
Oxygen
What semipermeable means?
Semipermeable means that somethings can pass through a barrier and some things can not. There are many examples: glass in windows allow light but not wind, our cell membranes allow water to move in and out but not proteins or glucose.
