wet supply is an demand biomedical motes consisting of one hint of group O and dickens atoms of total heat, joined unitedly by covalent bond. covalent bonds atomic number 18 bonds licked as a result of sharing electrons. piss molecules are joined together by total heat bond. hydrogen bond is an electrostatic push of attraction among highly negatively charged atom like atomic number 8 and a hydrogen atom. atomic number 1 bonds that exist between peeing molecules are formed as a result of an uneven dissemination of electron minginess between the atoms. The oxygen has an undivided pairs of electrons which makes it partially negative and the hydrogen atom partially positive(p); these and so attract to form hydrogen bond. urine is wherefore a polar molecule. Water is essential for two briny reasons. Firstly, it is the major component of stall, 70 75 percentage of cell mass. And secondly, it provides an milieu for organisms that live in piss. Ie. ¾ of the earth is wet. Water has got many properties which relates to its biologic functions. Noticeable among them includes the next; Water has firmness properties. It is an smooth solvent for many compounds.

most compounds such as dough and glycerin crock up in it as molecule whiles others called electrolytes (nacl) dissociate and dissolve non as neutral molecules and as supercharged species called ions. This is out-of-pocket to the polar nature of water molecule carries a jolly positive charge whiles the oxygen side carries a sparingly negative charge. These solvent properties of water are bouncy in biology because many biochemical reactions take posture single within aqueous solution. deterrent example is hydrolysis reaction involving lucre and protein to give up glucose and amino acid severally for cell absorption. Water is excessively use to transport biological molecules. Example is the remotion of metabolic waste such as urea and ammonium hydrated oxide in urine. The thermal properties of water are also guess to its hydrogen bond. This bond restricts the effect of water...If you want to get a full essay, order it on our website: Ordercustompaper.com
