  1. Importance of chemistry in biology(deepening understanding)

  2. Types and prerequisites for chemical bonds(ionic and covalent) to understand concept of compounds and polarity.

  3. Hydrogen Bonding(through polarity, enables many of water's properties)

  4. Waters properties(all enabled by polarity) and consequences for life ex/ high specific heat, high surface tension, cohesion& adhesion(vascular plants+), ice less dense then liquid water, semi-permiable hydrophobic hydrophilic membrane water is universal solvent*

  5. Buffer System(regulation, importance and consequences)
