SYI-1.A
Explain how the properties of water that result from its polarity and hydrogen bonding affect its biological function
SYI-1.A.1 The subcomponents of biological molecules and their sequence determine the properties of that molecule
SYI-1.A.2 Living systems depend on the properties of water that result from its polarity and hydrogen bonding
SYI-1.A.3 The hydrogen bonds between water molecules result in cohesion, adhesion, and surface tension
In this video Paul Andersen explains how the polarity of water makes life on the planet possible. Oxygen is highly electronegative and pulls the electrons closely creating a partial negative charge. The polarity of water (and the corresponding hydrogen bonds) create cohesion, adhesion, capillary action, high specific heat, and a universally good solvent.
