1.Chemistry: any compound that produces hydroxide ions (OH-) in water and raises its pH above 7. Genetics: one of four molecules making up a strand of DNA.
4.pH is a measure of the acidity or basicity of an aqueous solution
5.Substance that changes color when it comes in contact with an acid or base; Indicators are used to identify acidic and basic substances.
9.A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place
12.In chemistry, the term usually describes a single constituent, but in specialized fields the term can also mean chemical mixtures, even up to the level of cellular materials.
13.A highly irritating, greenish-yellow gaseous halogen, capable of combining with nearly all other elements, produced principally by electrolysis of sodium chloride and used widely to purify water, as a disinfectant.
17.Water Scale is a coating or precipitate deposited on surfaces that are in contact with hard water. Water that contains carbonates or bicarbonates of calcium or magnesium is especially likely to cause scale
18.A corrosive substance is one that will destroy or irreversibly damage another surface or substance with which it comes into contact. The main hazards to people include damage to the eyes, the skin, and the tissue under the skin; inhalation or ingestion.
19.Nitrate (NO 3) is a compound of nitrogen and oxygen found in nature and in many food items in our diet.

22.To exert a reciprocal or counteracting force or influence —often used with on or upon.
23.A reservoir is an artificial lake is used to store water.
2.Any compound that produces hydrogen ions (H+) in water, and reduces its pH level to below 7.
3.Domain of single-celled organisms that lack a nucleus; The term also refers to organisms in the kingdom eubacteria.
4.A chart where all elements are organized into periods and groups according to their properties.
6.Smallest particle into which an element can be divided and still have the properties of that element.
7.A substance that is building blocks of all matter; An element is made up of one of atom.
8.Describes a chemical substance that is neither an acid nor an alkali
10.Water that collects in cracks and spaces in the rocks and sediments beneath Earth’s surface.
11.Smallest particle of a substance that still has the properties of that substance.
13.Matter elements; The elements in a compound are chemically bonded, cannot be separated by physical means, and a compound has the elements that make it up made of two or more.
14.To free from infection especially by destroying harmful microorganisms.
15.Hard water is water that has high mineral content.
16.The material that all objects and substances are made of; anything that has mass and takes up space.
