When two solvents are separated by a semipermeable membrane water flows from low solute concentrations to high solute concentrations. What would happen if external pressure is applied to the solution?

"Water ALWAYS follows the salt" or to put it another way, it will try to make the two sides have equal amounts of water. The water will go where there are more solute particles. Water easily passes from one side to the other by simple osmosis.

Why does the level of a more concentrated solution rise when two solutions of different concentrations are separated by a semipermeable membrane and when does it stop rising?
The more concentrated solution is hypertonic and osmotic pressure (a hydrostatic force whose sole purpose in life is to make concentrations equal) tends to move solvent into the more concentrated solution. It will stop rising when either a) the solution concentrations are the same on both sides of the membrane, or b) when the osmotic pressure becomes equal to the ambient air pressure.
What keeps cells contents separated from external environment?
Cell contents are separated from the external environment by the cell membrane. Cells are also separated by the external environment when they are in the bloodstream in the capillaries and veins.
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
Is a bubble semipermeable?
no because it has no membrane
All cells are surrounded by a membrane Which is a characteristic of a cell membrane?
It is semipermeable.
What is the term of diffusion of water across a semipermeable membrane?
The term for the diffusion of water across a semipermeable membrane is osmosis. Osmosis is when the molecules of a solvent move from a less concentrated solution to a more concentrated one. This equalizes the concentrations on each side of the member.

What does osmosis do in a cell?
the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane.
What keeps cells contents separated from external environment?
Cell contents are separated from the external environment by the cell membrane. Cells are also separated by the external environment when they are in the bloodstream in the capillaries and veins.
How is the nucleus of a cell separated from the cytoplasm?
The nucleus as a whole is not separated from the cytoplasm, which surrounds it. However, the contents of the nucleus (DNA and assorted proteins) is separated from the cytoplasm by the nuclear membrane (a.k.a the nuclear envelope), which is the outer portion of the nucleus.
Cleansing the blood via a semipermeable membrane is called?
semipermeable

What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
What is the name of the pressure that must be exerted on a solution to prevent the passage of solvent molecules into a solution when the solution and solvent are separated by a semipermeable membrane?
Osmosis.
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
The external auditory meatus and middle ear cavity are separated by the stapes?
tympanic membrane
Cell Membrane?
The semipermeable membrane surrounding the cytoplasm of a cell
