You are taking a cruise from California to Hawaii. About halfway there the ship begins to sink. You are able to board a lifeboat, but now you are floating in the ocean waiting to be rescued. After several days you are so thirsty that you bend over the side of the boat and drink lots of salty seawater. What happens to your body?
a) you get dehydrated because water is unable to cross the semi-permeable membranes of your cells.
b) since sea water consist of 96.5% fresh water (and only 3.5% salt) you will feel much better.
c) you get thirstier because of osmosis.
d) salt diffuses into your cells, water follows, your cells start to expand and you feel bloated.
e) you throw up because sea salt is toxic to humans.
