AP Biology · Unit 1: Chemistry of Life
1.1 Structure of Water and Hydrogen Bonding
In short
You must understand how the properties of water (cohesion, adhesion, surface tension, high specific heat capacity, and high heat of vaporization) result from its polarity and hydrogen bonding. You need to connect these properties to biological functions, such as the maintenance of homeostatic body temperature and evaporative cooling.

What else do you need to know about Structure of Water and Hydrogen Bonding?
The focus is on the formation of polar covalent bonds within water molecules and hydrogen bonding between them. You should also be able to describe characteristics of visual representations of these biological concepts and processes.
Can you do these?
- I can describe how living systems depend on water's polarity, high specific heat capacity, and high heat of vaporization to sustain life and maintain homeostasis.
How is Structure of Water and Hydrogen Bonding tested on the exam?
The AP Biology Exam requires you to make predictions and justify your reasoning in real-world scenarios, as well as interpret experimental results and perform data analysis. For this topic, you should be able to use visual representations to demonstrate your understanding of water's properties in biological systems. A common pitfall on free-response questions is the misuse of similar scientific terms (e.g., confusing 'protein' with 'proton'), which can result in a failure to earn points. You must use precise and appropriate terminology.
