Повторение биологии уровня A «Водородные связи в воде»

You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/a-level-revision-videos/a-level-biology/ In this video, we start looking at the importance of water in Biology. First we explore the structure of the water molecule and see how water molecules are attracted to each other by forces called hydrogen bonds. We then look at the roles of water in Biology. These include as a habitat (both liquid water and ice) and how water can be used to cool organisms.
