2. Clearly explain how hydrogen bonds are formed using water as an example. [Hint: Include electron structure of water and include what relative electronegativities are and how they work to develop partial +/- charges.]
3. Define osmosis and characterize isotonic, hypertonic and hypotonic solutions and what happens to the cell(s) when placed into these solutions and the direction of water movement if any. Also, state which tonicity is optimal for animal cells and why.
4. Describe in detail how the sodium/potassium pump works and give at least one example of why it is important in the body.
