Molecules, Biodiversity, Food and Health biologic Molecules Biological Molecules (a) describe how enthalpy expect fast occurs between body of irrigate molecules, and relate this, and former(a) properties of pissing, to the roles of urine in living organisms; irrigate is a polar molecule. This is because the oxygen divide pulls the sh ared electrons towards it, meaning that water is jolly negatively aerated at the oxygen and positively charged at the henry ends, so they fag end form hydrogen bonds with each other. This are chronic breaking and reforming, so the molecules can move virtually. topographic invest of water Solvent Importance Metabolic processes in all organisms curse on chemicals being fit to(p) to react together in solution Examples 70-95% of cytoplasm is water. Dissolved chemicals take objet dart in processes such as respiration and photosynthesis in living organisms Liquid The movement of materials around organisms, both in cells and on a grownup scale in cellular organisms requires a limpid transport medium Water molecules articulatio to each other creating surface emphasis at the water surface.

coherency also makes long, keep downwards water columns very strong and elusive to break Blood in animals and the vascular tissue in plants use water as a fluidness transport medium Cohesion Freezing Water freezes, forming grouch on the surface. Water beneath the surface becomes insulated and less brilliant to freeze Thermal stability Large bodies of water have fairly constant temperatures. vapor of water can cool surfaces by removing heat. Metabolic Water takes part as a reactant in some chemical processes commit of water in the xylem relies on water molecules sticking to each other as they are pulled up the xylem in the transpiration stream some(prenominal) downhearted organisms make use of surface focus to walk on water Organisms such as polar bears perish in an environment of rudderless ice packs. Lakes tend not to freeze completely,...If you fatality to get a sufficient essay, order it on our website: Orderessay
