,Chapter 1 Introduction: Themes in the Study of Life
The introduction to the study of biology in Chapter 1 highlights seven book -wide themes, with special
emphasis on the core theme of evolution. How scientists use inductive reasoning to draw general
conclusions and deductive reasoning to test hypotheses is emphasized. Questions in this chapter are
designed to help assess a student’s understanding of the content of Chapter 1 based on the three key
concepts.
Multiple-Choice Questions
