During diffusion, molecules move...
- A.
From areas of low concentration to areas of high concentration.
- B.
From areas of high concentration to areas of low concentration.
- C.
By active transport.
- D.
Only through selectively permeable membranes.
Correct Answer
B. From areas of high concentration to areas of low concentration.Explanation
During diffusion, molecules move from areas of high concentration to areas of low concentration. This is because diffusion is a passive process that occurs due to the random movement of molecules. Molecules naturally move from an area where they are more concentrated to an area where they are less concentrated in order to achieve equilibrium. This movement continues until the concentration of molecules is equal throughout the entire system. Therefore, the correct answer is from areas of high concentration to areas of low concentration.Rate this question:

What happens to an animal cell placed in a hypotonic environment?
- A.
The cell will shrink due to the movement of water out of the cell.
- B.
The cell will remain the same size because the movement of water into the cell will equal the movement of water out of the cell.
- C.
The cell will swell dut to the movement of water into the cell.
- D.
The cell will swell dut to the movement of solute into the cell.
Correct Answer
C. The cell will swell dut to the movement of water into the cell.Explanation
When an animal cell is placed in a hypotonic environment, the concentration of solutes outside the cell is lower than inside the cell. As a result, water will move into the cell through osmosis, causing it to swell or expand. This is because water moves from an area of lower solute concentration (outside the cell) to an area of higher solute concentration (inside the cell) in an attempt to equalize the concentration on both sides. Therefore, the correct answer is that the cell will swell due to the movement of water into the cell.Rate this question:
