Can you describe how hydrogen bonding occurs between water molecules?
A hydrogen bond is the electrostatic attraction between polar groups that occurs when a hydrogen (H) atom bound to a highly electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F)

Can you relate hydrogen bonding, and other properties of water, to the roles of water in living organisms?
Water has a high boiling point due to the hydrogen bonds. Water is less dense as a solid. Water has cohesive properties-it travels as one mass. Adhesive-sticks to other materials (makes them wet). Is a good solvent. Acts as a coolant.

Can you explain the concept of monomers and polymers?
Monomers are small molecules that can bond together to form a polymer, a chain of monomers.
3 of 5
Can you explain the importance of condensation and hydrolysis reactions in a range of biological molecules?
In a hydrolysis reaction bonds are broken down. Condensation is when H2O is formed as the byproduct. An example: Happens in the bonding of phosphates to sugar and the sugar to the base.
