What ensures that solute concentrations are equal on both sides of a semi-permeable membrane?
  1. Inactive transport
  2. Active transport
  3. Facilitated diffusion
  4. Osmosis
Explanation
Answer - D - Osmosis ensures that solute concentrations are equal on both sides of a semi-permeable membrane. Osmosis is the movement of water across a semi-permeable membrane from an area of lesser solute concentration to an area of greater solute concentration. This movement occurs until the solute concentrations on both sides are equal.
