------------------------------------------------- Water The water molecule is a molecule which is made up from 2 hydrogen atoms and 1 oxygen atom. It is bounded by 2 covalent bonds and has is polar. The reason why water molecules are important for living organisms are because: 1. They are important solvents since they are polar 2. Important coolants for excessive metabolic reactions 3. Important for insulation since they have high specific heat capacities

Unknown Microorganisms May 1‚ 2013 This paper is based on an experiment done in the laboratory over a period of time using the standard method of identifying an unknown microorganism relying on features such as morphology‚ arrangements and biochemical reactions. It was done in succession with each step complimenting the other. At the end of the experiment three microorganisms Bacillus azotoformans‚ Staphylococcus aureus‚ and Escherichia coli was identified and one result was inconclusive. The
