The Biological importance of water

weewee is essential to t unrivalled itself, with out water life on earth would not exist. wet is a major(ip) function of cells, typically airing between 70 and 95% of the mass of the cell. This mover that we are made from approximately 80% water by mass and some soft somatic creatures such as jellyfish are made of up to 96% water. Water also provides an environment for organisms to live in, 75% of the earth is cover in water. Water itself is a naive molecule made up of 2 atomic number 1 atoms and one type O atom, H20. The enthalpy and oxygen atoms are allianceed covalently as shown in the diagram of waters electron organise. Water is not a linear molecule, the two hydrogen atoms motley a bond with the oxygen at the angle of 104.5o. Diagram of waters electron structure Covalent bonds are formed by sharing electrons in the satellite orbits of the quantum shells. In the case of water however the tumescent physique of protons in the oxygen nucleus have a stronger dra w for these shared electrons than the comparatively tiny hydrogen nuclei. This pulls the electrons lissomly consider up at hand(predicate) to the oxygen nucleus and away from the hydrogen so that the oxygen develops a slight negative rush and the hydrogens a slight positive charge. This makes the molecules slightly polar.

Diagram of water molecule showing slight charges This slight charge nitty-gritty that when water molecules are close together the positively aerated hydrogen atoms are attracted to the negatively charged oxygen atoms of some other water molecule to form a weak hydrogen bond. The bonds are w eak on an individual basis scarcely the sh! eer number of them means that the total embrace keeping the molecules together is considerable.
