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
1) Which of the following properties or processes do we associate with living things?
A) evolutionary adaptations
B) energy processing
C) responding to the environment
D) growth and reproduction
E) all of the above
Answer: E
Topic: Overview
Skill: Knowledge/Application
2) Which of the following is not a theme that unifies biology?
A) interaction with the environment
B) emergent properties
C) evolution
D) reductionism
E) structure and function
Answer: D
Topic: Concept 1.1
Skill: Knowledge/Application
3) Which of the following sequences represents the hierarchy of biological organization from
the least to the most complex level?
A) organelle, tissue, biosphere, ecosystem, population, organism
B) cell, community, population, organ system, molecule, organelle
