Answer:
Explanation:
Active cellular transport:
- It is the movement of molecules against the concentration gradient (from low concentration to high).
- Active transport requires expense of energy supplied by ATP.
- It is a rapid way to transport of large sized molecules.
Passive cellular transport:
- It is the movement of molecules along the concentration gradient (from high concentration to low).
- Passive transport does not require expense of energy.
- It is a slow process and small sized molecules get transprorted.
Contaminated lands and environments cause health difficulties such as cancer, can effect the respiratory system, and problems on the skin.
