Question

Osmosis involves?

1) the movement of a solvent, like water.
2) differences in solute concentrations.
3) movement from hypotonic to hypertonic solutions.
4) all of these except e.
5) all of these except c and d.

Answer 1

Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration.

Step-by-step explanation:

Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. Water moves into and out of cells by osmosis. If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic. Cells placed in a hypotonic solution will take in water across their membrane until both the external solution and the cytosol are isotonic.
