Water is the substance which presented life to our planet. Without its presence there would be no plants and animals, there would be no that variety of flora and fauna which fills Earth today. Thanks to water all live supports the activity and reproduces posterity.
Biological principle
Water is a liquid which at contact with a living organism does not cause it damages and does not break integrity of its fabrics. It is connected with neutral alkaline and acid properties of water. In an organism it enters only controlled biochemical processes. This only thing on the planet substance which under normal conditions is in a liquid, drinkable look, besides, in such abundance.
Water as universal solvent
If to give to this unique liquid necessary time, it will be able to dissolve any substance in any state. The substances dissolved in water easily dissociate on ions. And if to consider that all biochemical reactions happen only between ions of molecules, it is possible to draw a conclusion - water is optimum liquid for activity of all organisms.
The dielectric permeability of water is equal to 81 units. It is the highest indicator among all liquid substances.
Participation in chemical reactions
By means of water in a living organism fats, proteins and carbohydrates are split. In the course of these reactions the energy necessary for optimum existence of life is emitted. Thanks to water, in plants there is a reaction under the name photosynthesis. Oxygen, still necessary for activity is as a result formed.
Thermal control
Surprisingly, but water in an organism is responsible for maintenance of optimum body temperature regardless of environmental conditions. Thanks to this unique liquid, heat is distributed on an organism evenly. If ambient temperature rises up to 40 wasps or will fall to - 30 wasps, organism temperature all the same will remain acceptable for maintenance of the vital functions.
Elasticity of cages
In liquid state water cannot almost be compressed. In this regard she acts as a skeleton for a cage and keeps the correct shape of bodies.
Internals of beings are in the liquid water environment. Thanks to it, they are not injured during the falling, the movement and overloads of an organism.
Transport of substances
Plants and animals are saturated with nutrients and minerals thanks to unique property of water. It dissolves practically any substances. Water is one of the main components of blood of animals, it plays an important role in the systems of blood circulation and allocation. Plants receive mineral salts and macrocells thanks to the same properties of wonderful liquid.
