20Kelly and Pat are stranded on a desert island in the middle of theocean. They both are very thirsty and search for water, but don’t find any fresh water on the island. Kelly decides to drink ocean waterdeciding that although it tastes salty, it doesn’t taste terrible. Pat, onthe other hand, decides to drink coconut milk. As the day wears on,Kelly mdrinks more ocean water and complains of being thirstier. Pat,however, isn’t complaining at all. Why might Kelly still be thirsty?

a. Osmosis has depleted the water of Kelly’s cells, causing thirst.b. Osmosis has put more salt into Kelly’s cells, causing thirst.c. The salt from the ocean water has held more water in Kelly’s cells.d. Coconut milk contains about half the salt that ocean water does.
