Campbell's Biology, 9e (Reece et al.)
Chapter 1 Introduction: Themes in the Study of Life
This introductory chapter explores the basic themes and concepts of biology, with emphasis on the core
theme of evolution. It also introduces students to the thinking of scientists. Questions are therefore
general; however, an effort has been made to include some from each skill level. As in the rest of this
test bank, questions that feature art or those for which several questions follow upon some data or a
scenario are placed together at the end of the chapter.
Multiple-Choice Questions
1) A localized group of organisms that belong to the same species is called a
A) biosystem.
B) community.
C) population.
D) ecosystem.
E) family.
Answer: C
Topic: Concept 1.1
Skill: Knowledge/Comprehension
2) Organisms interact with their environments, exchanging matter and energy. For example, plant
chloroplasts convert the energy of sunlight into
A) the energy of motion.
B) carbon dioxide and water.
C) the potential energy of chemical bonds.
D) oxygen.
E) kinetic energy.
Answer: C
Topic: Concept 1.1
Skill: Knowledge/Comprehension
3) The main source of energy for producers in an ecosystem is
A) light energy.
B) kinetic energy.
C) thermal energy.
D) chemical energy.
E) ATP.
Answer: A

but do not have their DNA encased within a nuclear envelope?
A) animal
B) plant
C) archaea
D) fungi
E) protists
Answer: C
Topic: Concept 1.1
Skill: Application/Analysis
5) To understand the chemical basis of inheritance, we must understand the molecular structure of DNA.
This is an example of the application of which concept to the study of biology?
A) evolution
B) emergent properties
C) reductionism
D) the cell theory
E) feedback regulation
Answer: C
Topic: Concept 1.1
Skill: Application/Analysis
6) Once labor begins in childbirth, contractions increase in intensity and frequency until delivery. The
increasing labor contractions of childbirth are an example of which type of regulation?
A) a bioinformatic system
B) positive feedback
C) negative feedback
D) feedback inhibition
E) enzymatic catalysis
Answer: B
Topic: Concept 1.1
Skill: Application/Analysis
7) When the body's blood glucose level rises, the pancreas secretes insulin and, as a result, the blood
glucose level declines. When the blood glucose level is low, the pancreas secretes glucagon and, as a
result, the blood glucose level rises. Such regulation of the blood glucose level is the result of
A) catalytic feedback.
B) positive feedback.
C) negative feedback.
D) bioinformatic regulation.
E) protein-protein interactions.
