Chapter 1 The Science of Life

Chapter 1: you should be able to… Describe the importance of Biology in society. List and understand the characteristics of living things. Distinguish between homeostasis and metabolism. Use the Scientific Method in order to effectively communicate the results of a controlled experiment. Identify the parts and functions of a compound light microscope Compare/Contrast 2 types of electron microscopes.

The World of Biology Biology and You Biology and Society Informed decisions What are you interested in? Controversies? New technologies?
