A temperature scale with its units in Kelvin

The theoretical lowest possible temperature. It is the theoretical temperature at which entropy reaches its minimum value.

The rate at which the velocity of a body changes with time

value

Commonly used to mean the deposition of acidic components in rain, snow, fog, dew, or dry particles. The more accurate term is acid precipitation. Clean or unpolluted rain has a slightly acidic pH of 5.6, the extra acidity in rain comes from the reaction of air pollutants, primarily Sulphur dioxide and Nitrogen oxides, with water in the air to form strong acids (like sulphuric and nitric acid). The main sources of these pollutants are vehicles and industrial and power-generating plants.

The energy required to initiate a chemical reaction or process, abbreviated Ea

The opposite of passive transport, active transport involves the input of energy , the building of concentration gradients, and the action of a membrane pump to create high concentrations of molecules.

A process where heat does not enter or leave a system

An organism or cell that requires oxygen to carry out its metabolic processes; a process that requires oxygen.

The release of chemicals and particulates into the atmosphere. Common gaseous pollutants include carbon monoxide, sulfur dioxide, chlorofluorocarbons (CFCs) and nitrogen oxides produced by industry and motor vehicles. Photochemical ozone and smog are created as nitrogen oxides and hydrocarbons react to sunlight. Particulate matter, or fine dust is characterized by their micrometre size PM10 to PM2.5.

A measurement of the pollutants in the air

Unicellular or multicellular organisms formerly classified as plants, occurring in fresh or salt water or moist ground, that have chlorophyll and other pigments but lack true stems, roots, and leaves

 Mostly aquatic plantlike organisms that range in size from one cell to large multi-celled seaweed and are photosynthetic.

The rate of change of angular displacement with respect to time.

A negatively charged ion that migrates to the anode in an electrical cell.

These are values in a set of results which are judged not to be part of the variation caused by random uncertainty

A medicine  that inhibits the growth of or destroys microorganisms.

Specialized cells of the immune system which can recognize organisms that invade the body (such as bacteria, viruses, and fungi). 

A blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood
