Osmosis Involves

Question

Osmosis involves
A) The movement of dissolved salts across a membrane
B) The movement of dissolved salts and pure water across a membrane in one direction
C) The movement of pure water across a membrane in the direction of higher salt concentration
D) Behavior that allows an individual to move to a habitat with favorable salinity

Accepted Answer

Osmosis specifically refers to the movement of water molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration until equilibrium is reached. This process does not involve the movement of salts across the membrane, but rather the movement of water towards the area of higher salt concentration.
