You are working with cells that have an internal solute concentration of 5mM solute. This solute is large and ionized. You place them in a medium that has a concentration of 7.7 mM solute. What will happen? a. The cells will swell initially, then return to their original size. b. The cells will shrink in size. c. I do not expect anything to happen. d. The cell will burst.

Red blood cells shrivel when placed in a 10% sucrose solution. When first placed in the solution, the solute concentration of the cell is______ the concentration of the sucrose solution. After the cells shrivel, their solute concentration is______ the concentration of the sucrose solution. A. Greater than... equal to B. Equal to... equal to C. Less than... greater than D. Less than... equal to E. Greater than... less than

Model 1 and Model two are diagrams showing the process of two types of bulk transport which require energy. Which of the following statements correctly describes the type of transport that is occurring in Model 1 and Model 2? A . Model 1 and 2 are types of passive transport. B . Model 1 and 2 help to transport only one molecule at time. C . Model 1 shows endocytosis, where the cell surrounds molecules from outside the cell and takes the molecules into the cell. D . Model 2 shows endocytosis, where the cell surrounds molecules from inside the cell and releases them outside of the cell.

Suppose that you have a splinter that is embedded so deep in your foot that you cannot remove it with tweezers. How could you use what you learned in this unit as a first-aid remedy in this situation? Select one: O A. Use active transport to your advantage to draw water into your foot. O B. Use osmosis to your advantage by placing your foot in a hypotonic solution. C. Use osmosis to your advantage by placing your foot in a hypertonic solution. D. Use an artificial concentration gradient to draw water into your foot. E. Use osmosis to your advantage by placing your foot in an isotonic solution.
