   2.Uncharged

Question 15

The natural tendency of molecules to move from higher to lower concentrations is

Answer 15

diffusion

Question 16

Of the five transport mechanisms, which one will the cell utilize if the substance being transported is insoluble?

Answer 16

facilitated diffusion

Question 17

Why do O2 and CO2 pass through the plasma membrane?

Answer 17

they are nonpolar and soluble
