Question 1 of 25

1. Question
What is the definition of active transport?
- The movement of substances from a more dilute solution to a more concentrated solution
- The movement of substances from a more concentrated solution to a more dilute solution
- Net movement of water molecules from an area of higher to lower concentration across a partially permeable membrane
- Spreading out of particles

Question 7 of 25

7. Question
Which way do substances move overall in active transport?

Question 15 of 25

15. Question
A plant has low levels of glucose. What does this mean?
