Question

question 8 (1 point) if two solutions of different tonicity are separated by a selectively permeable membrane, the solvent (water) will pass the membrane until both solutions are hypotonic. isotonic. hypertonic.

Explanation:

Tonicity refers to the relative solute concentration of two solutions separated by a selectively permeable membrane. Water moves via osmosis from an area of lower solute concentration (hypotonic) to higher solute concentration (hypertonic) until the solute concentrations (and thus tonicity) of both solutions are equal. When solutions have equal solute concentrations, they are isotonic. Hypotonic means a lower solute concentration, and hypertonic means a higher solute concentration; these are states before equilibrium, not the end result of osmosis between two different tonicity solutions.

Answer:

B. isotonic.
