2. Large sample size
3. Performed for longer periods of time.
4. One variable tested
5. Peer reviewed
6. Does not have to agree with hypothesis
7. Unbiased
500
Movement of molecules from high concentration to low concentration.
(Requires no energy)
What is diffusion?
500
Requires the use of energy, usually moving molecules from a low concentration to high concentration.
What is Active Transport?
500
The diffusion of water into or out of the cell.
What is diffusion?
in cell-cell swells and can burst
loses water ( being put in salt water) shrivels up
