If you are stranded at sea (oh no!) why is it safer to drink urine than sea water?

• One cup of sea water has enough sodium to poison you.
• Sea water is hypertonic to your cells and will only further dehydrate you.
• Sea water is too isotonic to your cells and you will absorb too much water.
• The salt will cause high blood pressure and you will die from a stroke.

Inside osmosis bag A (semipermeable membrane), there is a 50% glucose solution.  Inside osmosis bag B there is a 20% glucose solution.  Both bags are placed into beakers containing distilled water.  What will occur?

• Bag A will gain mass.
• Bag B will gain mass.
• Both bags will gain mass.
• Both bags will lose mass.

0.9% NaCl is isotonic to red blood cells.  Which of these describes what will happen if a technician misplaces a decimal point and makes 9.0% NaCl solution instead and administers it to a patient?

• The cells exposed to the solution will burst.
• The cells exposed to the solution will shrink.
• The cells will remain the same size.
• The cells exposed to the solution will expand but not burst.
