IB Bio A1.1 Water Questions and Answers Graded A+ List reasons why water is a substance on which life depends. A1.1.1 - Water as medium of life. 1. The first cells originated in water. 2. Water is the "universal solvent" allowing it to dissolve and transport molecules around a body. 3. Water is a metabolite in condensation and hydrolysis reactions. 4. Water is a temperature buffer in bodies and ecosystems. 5. Water maintains biological structures (such as phospholipid bilay...

MCAT Study Setcovalent bond formed via the sharing of electrons between two elements of similar EN bond order refers to whether a covalent bond is a single, double, or triple bond. As bond order increases, bond strength increases, bond energy increases, bond length decreases ionic bonds formed via the transfer of one or more electrons from an element with a relatively low IE to an element with a relatively high electron affinity - cation: postiive - anion: negative elect...
