Which red blood cell was placed in a hypotonic solution?

• A
• B
• C
• none of them

The difference in the concentration of a substance from one location to another is called.....

• diffusion
• osmosis
• concentration gradient
• passive transport

Which way will the water molecules in the image move during osmosis?

• Out of the cell, so the cell shrinks
• Out of the cell, so the cell swells
• Into the cell, so the cell shrinks
• Into the cell, so the cell swells

Iodine turns dark purple when in contact with starch. After an hour, the solution in the dialysis tubing turned dark purple. Why?

• The starch in the tubing diffused out.
• The iodine and water diffused in.
• The iodine changed into starch.
• The starch changed into iodine

In this picture, which way will the water move?

• Water will move into the cell
• Water will move out of the cell
• Water will move in and out of the cell
• Water will not move
