Temperature range Background: All organisms are adapted to a particular environment with its characteristic temperature range. The temperature range allows the organism’s enzymes to control its metabolism by operating at their optimum efficiency within this range. Some organisms are adapted to live at high temperatures (80 - 100oC) and these are called thermophiles

The first known use of the word in biological text was in 1961 when employed to describe the breakdown of material into the base components of carbon‚ hydrogen‚ and oxygen by microorganisms. Now biodegradable is commonly associated with environmentally friendly products that are part of the earth’s innate cycle and capable of decomposing back into natural elements. Biodegradation is the chemical dissolution of materials by bacteria or other biological means. Biodegradable matter is generally organic

Evolution by natural selection is slow but can be observed in certain situations. How to spot evolution in real time: Artificial selection – manipulation by humans such as breeding dogs or growing corn. Repro-rate – rate of reproduction. Stochastic Event: unexpected disaster like a volcano eruption or tornado. (Research geological time) LIVING THINGS: Biology – Study of living things. Living things – all the organisms descended from a single-celled ancestor. * Characteristics:
