Explanation:

1. Hydrological cycle: the continuous movement of water between the Earth's surface and the atmosphere.

2. Industry: pollutes water sources by dumping wastes in rivers, streams, and oceans.

3. Sewage: the leading cause of water contamination in countries without water treatment plants.

4. Agriculture: a source of water pollution caused by the overuse of pesticides and fertilizers.

5. Eutrophication: caused by an overabundance of organic matter in water supplies.

6. Putrefaction: the decomposition of organic matter by microorganisms

7. Pesticides: a chemical pollutant that can enter the water cycle through agricultural or domestic use.

8. Petroleum: can cause the contamination of underground water supplies if poured on the ground

9. Lead: a metal that leaks into water supplies via the soil or aging water systems.

10. Humoral immunity: depends upon the production of disease-specific antibodies to destroy harmful bacteria.

11. Stimulants: increases the activity of the central nervous system.

12. Depressants: reduces the activity of the central nervous system.

13. Bacterial infection: caused by the reproduction of a small infectious agent, which produces poisons that destroy cells
