Red blood cells (internal solute concentration 0.30 M) are placed in Solution Z containing 0.30 M nonpenetrating solute. The membrane is permeable to water but not to the solute. The cells begin at normal volume and are observed for 10 minutes while the external concentration remains constant. Water movement depends on relative solute concentrations across the membrane. Which outcome is most likely?
