Yes, due to its very small molecular size - unless of course it is frozen.

Are solutes always able to diffuse through a cell's selective permeable membrane?
No, cell membranes are semi-permeable, meaning they allow some solutes to pass through - but not others.
What substance can diffuse through a differentially permeable membrane?
Diffusion across a membrane in biology is referred to as 'osmosis' & osmosis is the process by which solvent molecules move from a region of high conc. to low concentration and this can therefore occur only in one direction at a time for a perticular solution. this is a really smart answer im surprised
Is the Visking tubing a partailly permeable membrane and why?
Yes, it is a partially permeable membrane. It allows certain substances like glucose and water molecules to diffuse through but not large molecules like starch and sucrose. Selectively permeable.
How is Osmosis in red blood cells?
Osmosis is the diffusion of molecules from where they are abundant to where they are scarce through a semi permeable membrane. In red blood cells, this semi permeable membrane is the cell membrane. If red blood cells were placed in a solution abundant with water molecules, they would diffuse into the cells through the membrane
What properties does a selective permeable membrane have?
the ability to allow materials to cross a membrane
Are solutes always able to diffuse through a cell's selective permeable membrane?
No, cell membranes are semi-permeable, meaning they allow some solutes to pass through - but not others.
Is a membrane selectively permeable?
Selectively permeable means that only certain substances are able pass through the cell membrane.A selectively permeable membrane is a membrane that only can be permeated by selective things, in other words a surface that lets some molecules in but not others. Like a cell membrane will let water diffuse into it :)
Why do sugar molecules not diffuse through a plant cell membrane?
The membrane is semi-permeable. Sugar molecules are too large to diffuse through.

What is the term for a membrane that allows certain but not all molecules to diffuse through it?
semi-permeable.

How is the membrane permeability?
means that the cell membrane has some control over what can cross it, so that only certain molecules either enter or leave the cell
Is the Visking tubing a partailly permeable membrane and why?
Yes, it is a partially permeable membrane. It allows certain substances like glucose and water molecules to diffuse through but not large molecules like starch and sucrose. Selectively permeable.
In what way is a cell membrane selective?
very complicated question that is better addressed by a cell biology text but in general cell membrane itself is non-polar and allows small non-polar molecules through it also has protein that are built to selectively let in molecule based on commands from the body
What is the movement of water through a selectively permeable membrane?
The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.
What is the property of the cell membrane that allows only some materials to pass through it?
selectively permeable or selective permeability
What scientific idea is a dialysis machine based on?
is based on diffusion of waste substances through a selective permeable membrane
