The process you are referring to is called dialysis. It involves using a semipermeable membrane to separate molecules based on their size in a solution or colloid. The smaller molecules can pass through the membrane, while the larger ones are retained, allowing for purification or concentration of the solution.
Selective diffusion refers to the process in which only certain molecules are able to pass through a semipermeable membrane based on their size or charge. This process allows the cell to regulate what substances can enter or leave the cell.
The cell membrane surrounds the cytoplasm. It works as a semipermeable filter for those substances required by the cell. It is elastic in nature and grows along with the increasing volume of cytoplasm.
Cells transport molecules without using energy through three primary methods: diffusion, facilitated diffusion, and osmosis. Diffusion involves the movement of molecules from an area of higher concentration to one of lower concentration until equilibrium is reached. Facilitated diffusion utilizes specific transport proteins in the cell membrane to help polar or charged molecules cross the membrane along their concentration gradient. Osmosis specifically refers to the movement of water across a semipermeable membrane, also driven by concentration gradients.
Yes, it can. However since reverse osmosis (RO) produces a stream of waste water as it purifies incoming water, the amount of waste water produced by treating sea water via RO would be huge. The fact of the matter is that RO technology was originally invented to produce clean drinking water on ships during long ocean voyages. I would estimate that for every 1 gallon of clean water produced from sea water approximately 7-10 gallons of water would be wasted.

Solvent particles will move from an area of high concentration to low concentration across a semipermeable membrane until equilibrium is reached. This process is known as osmosis and is driven by the natural tendency of molecules to move from areas of high to low concentration to equalize the concentration gradient.
By reversing osmosis and using pressure to push the pure water through the semipermeable membrane, leaving concentrated salt brine behind.
Osmosis provides the primary means by which water is transported into and out of cells.

A reverse osmosis system purifies water by using pressure to push water through a semipermeable membrane, which filters out impurities and contaminants, leaving behind clean, purified water.

Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. Dialysis is a process that involves the separation of solutes in a solution using a semipermeable membrane, allowing smaller molecules to pass while larger ones are retained. Osmosis specifically refers to the movement of water, while dialysis is a broader term that can involve the separation of various solutes.
Using vinegar to remove stains from clothing can be effective for certain types of stains, such as sweat or deodorant stains. Vinegar's acidic properties can help break down the stain and lift it from the fabric. However, it may not be as effective for all types of stains, such as oil-based stains. It is recommended to spot test vinegar on a small, inconspicuous area of the fabric before using it on the stain.
Reverse osmosis uses a semipermeable membrane to separate salt and impurities from seawater, leaving behind pure drinking water. The high-pressure pump forces water through the membrane, where salts and other contaminants are removed. The purified water is collected on one side of the membrane, while the rejected concentrate containing the separated impurities is disposed of.
