OLD FRQ's  prior to 1995

(1996)  The unique properties (characteristics) of water make life possible on Earth.  Select three properties of water and:
        a.     for each property, identify and define the property and explain it in terms of the physical/chemical nature of water.
        b.    for each property, describe one example of how the property affects the functioning of living organisms.
