The thermal properties of water allow organisms to live in an environment with relatively
small changes in temperature. These properties also make water efficient as a coolant, e.g.
in sweating or by absorbing large amounts of heat
Outline how other properties of water are essential for sustaining life on Earth [6 marks]
Muscle contraction requires energy in the form of ATP.
Describe the different sources of the ATP that is used in muscle contraction during strenuous
exercise [6 marks]
