, Chapter 1: Introduction to Biology
1. Biology is best defined as the science that studies:
A. Chemical reactions in nonliving matter
B. Life and living organisms
C. The origin of the universe
D. Human behavior and cognition
Correct Answer: B
Explanation:
Correct option: Biology is defined as the study of life.
Distractors: A is chemistry/physical science focus, not life. C is astronomy/cosmology. D is
psychology, not the full scope of biology.
2. Which list contains the characteristics that, when considered together, are used to
define life in this chapter?
A. Growth, movement, photosynthesis, and consciousness
B. Order, sensitivity/response to stimuli, reproduction, adaptation, growth and
development, regulation, homeostasis, and energy processing
C. Respiration, digestion, circulation, and excretion
D. DNA, protein, cells, and evolution
Correct Answer: B
Explanation:
Correct option: The chapter specifies eight characteristics used to define life: order,
response to stimuli, reproduction, adaptation, growth and development, regulation,
homeostasis, and energy processing.
Distractors: A includes traits not required for all life (e.g., photosynthesis, consciousness). C
lists organ-system functions that do not apply to all organisms. D lists important biological
themes but not the chapter’s defining set.
3. In this chapter, adaptation is described as:
A. A sudden change in an individual organism during its lifetime to meet a need
B. A “fit” to the environment that results from evolution by natural selection and
enhances reproductive potential
C. The ability to keep internal conditions perfectly constant without change
D. The process by which cells divide to form two identical daughter cells
Correct Answer: B
Explanation:
Correct option: Adaptation is presented as a consequence of evolution by natural
selection that improves the ability to survive and reproduce.
Distractors: A misrepresents adaptation as a sudden need-based change in an individual.
