What are the four properties of water and an example.
Cohesion: Water is attracted to other water molecules - capillary action
Expansion upon freezing: Water becomes less dense when frozen - insulation
Ability to act as a solvent: can dissolve polar substances - allows blood to transfer materials
Moderate temperature: water has a high heat capacity - allows sweat

What is the difference between dehydration synthesis reaction and hydrolysis reaction?
Dehydration Synthesis Reaction: Breaks down bonds, polymers -> monomers, creates water
Hydrolysis Reaction: Creates bonds, monomers -> polymers, uses water
