Molecules, Biodiversity, Food and Health Biological Molecules Biological Molecules (a) describe how henry hold fast occurs between pissing molecules, and relate this, and former(a) properties of irrigate, to the roles of water in live organisms; Water is a polar molecule. This is because the atomic number 8 segment pulls the sh ared electrons towards it, meaning that water is slightly negatively supercharged at the oxygen and positively charged at the hydrogen ends, so they can form hydrogen bonds with distributively other. This are continuing breaking and reforming, so the molecules can move virtually. topographic point of water Solvent Importance Metabolic processes in all organisms rely on chemicals being adequate to(p) to match together in solution Examples 70-95% of cytoplasm is water. Dissolved chemicals spend a penny objet dart in processes such as respiration and photosynthesis in living organisms Liquid The movement of materi als around organisms, both in cells and on a large scale in cellular organisms requires a limpid transport medium Water molecules stick to each other creating surface tension at the water surface. viscidness also consecrates long, keep down water columns very inviolable and difficult to break Blood in animals and the vascular weave in plants use water as a bland transport medium Cohesion Freezing Water freezes, forming wish-wash on the surface. Water beneath the surface becomes insulated and less declare to freeze Thermal stability Large bodies of water go for fairly constant temperatures. vaporization of water can aplomb surfaces by removing heat. Metabolic Water takes part as a reactant in some chemical processes Transport 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) small organisms make use of surface tensi on to walk on water Organisms such as pola! r bears live in an environs of rudderless ice packs. Lakes tend not to freeze completely,...If you postulate to get a full essay, order it on our website: OrderCustomPaper.com
