Drinking seawater can be fatally harmful and is highly discouraged even in the most severe cases of dehydration. Which of the following provides the most likely cause for this fact? A B с D The increase in salt concentration in the extracellular environment will increase the per- meability of the cell membrane. The increase in salt concentration in the extracellular environment will cause the move- ment of water into the cell. The increase in salt concentration in the extracellular environment will cause the move- ment of water out of the cell. The increase in salt concentration in the extracellular environment will decrease the per- meability of the cell membrane.
