These notes cover everything in Module 1 of Principles of Biology. Chapter 1 starts out with the basics of biology, the features of all living organisms, biological organization, and the classification of biological diversity. Chapter 2 covers the chemical context of life, which includes matter, elements, atoms, ions, isotopes, chemical bonds, energy, and radioactivity. Chapter 3 dives deeper into water and how vital it is to life on earth, including its four emergent properties, concentration a...
