You are alone on an island in the middle of the Atlantic Ocean. You are hot and thirsty, so you want to drink water from the ocean. You think about biology class and you decide:

• to drink the ocean water because the extra salt will quench your thirst.

• not to drink the ocean water because the extra salt will cause you to dehydrate.

• to drink the ocean water because your cells will burn more fat due to the salt intake.

• not to drink the ocean water because the extra salt will cause your cells to burst.

Which of the following is NOT true?

• Animal cells in hypotonic solutions will burst.

• Plant cells in hypotonic solutions will not burst due to the cell wall.

The molecule pictured in the image is

• a phospholipid

• a carbohydrate

• a cholesterol

• a transport protein

Which image best represents facilitated diffusion?

• 
• 
• 
• 

Movement of a substance across a cell membrane against its concentration gradient from lower concentration to higher concentration. Energy required.

• osmosis

• diffusion

• facilitated diffusion

• active transport

Concentration (amount) of solutes is equal on both sides of the cell membrane; this allows the flow of water through the cell membrane to be equal.

• solvent solution

• isotonic solution

• hypotonic solution

• hypertonic solution
