When external pressure is applied to a solution separated by a semi-permeable membrane, it can counteract the osmotic pressure that drives water from the low solute concentration side to the high solute concentration side. This may lead to the reversal of osmosis, where water moves from the higher solute concentration side to the lower one, effectively diluting the more concentrated solution. If the pressure is sufficiently high, it can prevent water from flowing into the concentrated solution altogether, potentially leading to a state of equilibrium.

What is the cell structure that is located in the external boundaries of the cell?
The cell structure that is located in the external boundaries of the cell is the cell membrane. The cell membrane is a semipermeable membrane composed of lipids and proteins that surrounds the cell, providing a barrier between the cell's interior and its external environment.
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.
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 kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
Is a bubble semipermeable?
No, a bubble is not semipermeable. A bubble is a thin film of soapy water enclosing air or gas, which is not selectively permeable to different substances like a semipermeable membrane is.
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.

Could the skin be a semipermeable membrane?
Yes, the skin can be considered a semipermeable membrane. It regulates the passage of substances in and out of the body, allowing certain molecules to pass through while blocking others. This property helps the skin to maintain homeostasis and protect the body from external threats.
In osmosis does a solvent moves across a semipermeable membrane from an area of higher solution concentration to an area of lower solution concentration?
No, in osmosis the solvent (usually water) moves from an area of lower solute concentration to an area of higher solute concentration across a semipermeable membrane in an attempt to equalize the solute concentrations on both sides of the membrane.
Cleansing the blood via a semipermeable membrane is called?

What is the best definition of osomosis?
Osmosis is the process by which water molecules move across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration, in order to equalize the concentrations on both sides of the membrane.
Is a bubble semipermeable?
No, a bubble is not semipermeable. A bubble is a thin film of soapy water enclosing air or gas, which is not selectively permeable to different substances like a semipermeable membrane is.
How does water move in osmosis?
Osmosis moves a solvent (eg water) to balance the concentrations of solute either side of a semipermeable membrane. The solvent is not lost.If the concentration of a solution is higher on one side of the membrane than the other, then the water moves across the membrane from the less concentrated side to the more concentrated side to dilute it until the concentrations on either side are equal.
