Which of the following is NOT true?
A - Molecules will try to move so that there is equilibrium of concentration in all parts of a solution
B - Solute molecules will move across semi-permeable membranes to equalize concentration on both sides of the membrane
C - It is impossible to have more solvent in a solution than can be found in a saturated solution of the same components
D - Diffusion and osmosis are important to biological systems
Answer: B - Solute molecules move across semi-permeable membranes to equalize concentration on both sides of the membrane
Solvent molecules move across the membrane not solute.
