Answer:
4
Explanation:
Because the mean time taken to turn from blue/black to orange/brown (in minutes) was the shortest, showing that the rate of reaction was the highest.
Answer:
The statement is false.
Explanation:
Passive transport moves molecules from one side of the membrane to the other with the energy of the chemical gradient (or concentration gradient). Otherwise, active transport uses the hydrolyzation of ATP to gain energy in order to move molecules across the membrane without taking into account the gradient.
