Multiple Choice Questions
-
Question 1:
- Diffusion is the movement of molecules from high concentration to low concentration.
-
Question 2:
- Exocytosis is the bulk transport that moves materials away from the cell.
-
Question 3:
- Facilitated diffusion is a type of passive transport that uses a carrier protein to move substances across a membrane.
-
Question 4:
- Active transport moves large molecules, like fats and proteins, into a cell.
-
Question 5:
- A cell in a hypertonic solution will shrink (water leaves the cell).
-
Question 6:
- Water will move from the area with lower solute concentration (side B) to the area with higher solute concentration (side A).
