properties of water!
1. 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 funtioning of living organisms
the properties of waters are 1.)high specific heat. 2) high heat of vaporization. 3). high heat of fusion. 4). high surface tension.

Key in "water properties biology" in yahoo searchYou can find the following webpages:Water has a high specific heat. Specific heat is the amount of energy required to change the temperature of a substance. Because water has a high specific heat, it can absorb large amounts of heat energy before it begins to get hot. It also means that water releases heat energy slowly when situations cause it to cool. Water's high specific heat allows for the moderation of the Earth's climate and helps organisms regulate their body temperature more effectively.Water has a high surface tension (Figures 8a-3 and 8a-4). In other words, water is adhesive and elastic, and tends to aggregate in drops rather than spread out over a surface as a thin film. This phenomenon also causes water to stick to the sides of vertical structures despite gravity's downward pull. Water's high surface tension allows for the formation of water droplets and waves, allows plants to move water (and dissolved nutrients) from their roots to their leaves, and the movement of blood through tiny vessels in the bodies of some animals
http://www.physicalgeography.net/fundamentals/8a.h... heat of vaporization [evaporation] Because it also involves the breaking of hydrogen bonds, water resists vaporizing (evaporating). Consequently, it takes a lot of heat to evaporate water. This high heat of vaporization is also utilized by organisms as a cooling process, e.g., sweat or panting.http://www.mansfield.ohio-state.edu/~sabedon/biol1... of FusionThe heat required to convert a solid into a liquid with no temperature change. This is also called the latent heat of fusion or melting. The energy released in freezing of water and the energy needed for melting ice have a very important effect to the climate, because these processes smoothen the changes of the temperature in the spring and in the autumn, when the radiation from we get from the Sun is changing. There is a lot of water everywhere, not only in the lakes but also in the ground, in the air etc. Without this effect, the release and the binding of the energy, the changes of the climate would be much more radical than they are now. http://www.phnet.fi/koulutus/hollola/lukio/projekt...
