Water molecules move from a faucet through a garden hose when the faucet is turned on.___________
A dialysis bag contains 10% starch solution. The dialysis bag is placed in a beaker filled with deionized water. Ten drops of Starch indicator (iodine solution, KI) solution is placed into the deionized water. The water turns a yellowish-brown color, however, you notice that the starch solution begins to turn black. Describe what is happening with respect to the diffusion of starch.
This type of passive transport
• does not require ATP
• uses transport proteins to increase the rate of diffusion
• Helps transport polar molecule (H2O, H+). 2 words.________?
