Therefore, to understand living things, biologists needs a good understanding of chemistry. hydrogen bond the weak bond that forms between a hydrogen atom with a partial positive charge an atom with a partial negative charge like oxygen, nitrogen or fluorine.
Chemistry explains how your cells produce energy and proteins, why you breathe and have blood and what sorts of foods and vitamins are important for nutrition.
