Kelly and Pat are stranded on a desert island in the middle of the ocean. They both are very thirsty and search for water, but don’t find any fresh water on the island. Kelly decides to drink ocean water deciding that although it tastes salty, it doesn’t taste terrible. Pat, on the other hand, decides to drink coconut milk. As the day wears on, Kelly drinks 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.

Two students set up two experiments to see if both plant and animal cells have cell walls. Which of the following statements best describes correct conclusions?
a. Both student experiments show that plant cells have cell walls and animal cells do not have cell walls so it does not matter that each student used different experimental methods and procedures.
b. Both experiments showed that plant cells and animal cells have cell walls so it does not matter that each student used different experimental methods and procedures.
c. Both experiments showed that plant cells have cell walls and animal cells do not have cell walls so the two students obviously did the exact same experiment so they could get the same conclusion.
d. Both experiments showed that plant cells and animal cells have cell walls so the two students obviously had the same exact experiment so they could get the same conclusion.
