This document contains a study guide for Test 2 covering topics such as fossils, selective breeding, the scientific method, microscopy, cells, living organism characteristics, evolution, classification, and the environment. It includes questions about the key terms, concepts, and processes within each topic area as well as diagrams to label and calculations to perform. The goal is to assess the student's understanding of these fundamental biology concepts through completion of the study guide.
