, BIO 171 EXAM 2 — A&P, HOMEOSTASIS, GENE
Questions 1 – 44
EXPRESSION & CANCER BIOLOGY
1. Which of the following correctly lists the properties of all living things, including humans?
A. Organized, acquire materials and energy, maintain homeostasis, respond to stimuli,
reproduce and grow, have evolutionary history
B. Movement, consciousness, language, tool use, culture, technology
C. Photosynthesis, cellular respiration, fermentation, chemosynthesis
D. Excretion, digestion, circulation, respiration only
CORRECT ANSWER A — Organized, acquire materials and energy, maintain homeostasis,
respond to stimuli, reproduce and grow, have evolutionary history
RATIONALE Per the source material, all living things share six key properties: they are
organized (have complex structure), acquire materials and energy from the
environment, maintain homeostasis (stable internal conditions), respond to
stimuli, reproduce and grow, and have an evolutionary history. Options B, C, and
D describe specific functions or processes that are not universal to all living
organisms.
2. The level of biological organization where two or more different tissues combine to form
a structure is the:
A. Tissue Level
B. Organ Level
C. Organ System Level
D. Organismal Level
CORRECT ANSWER B — Organ Level
RATIONALE Per the source material, the Organ Level is where two or more different tissues
combine to form an organ (e.g., the heart contains muscle, connective, nervous,
and epithelial tissues). The Tissue Level (option A) involves a community of
similar cells. The Organ System Level (option C) involves two or more organs
working together. The Organismal Level (option D) involves all organ systems
functioning together.
, 3. The Organismal Level of biological organization is best described as:
A. Two or more different tissues combining to form a structure
B. Many organ systems working harmoniously together to perform the functions of an
independent organism
C. A community of similar cells forming body tissue
D. Atoms bonding to form molecules with three-dimensional structures
CORRECT ANSWER B — Many organ systems working harmoniously together to perform the
functions of an independent organism
RATIONALE Per the source material, the Organismal Level represents the highest level of
organization — all organ systems functioning together to create an independent,
living organism. Option A describes the Organ Level. Option C describes the
Tissue Level. Option D describes the Chemical Level.
4. The study of the body's structures and how living organisms work is called:
A. Physiology
B. Anatomy
C. Ecology
D. Histology
CORRECT ANSWER B — Anatomy
RATIONALE Per the source material, anatomy is the study of the body's structures — how
living organisms work and how their structures work together to function.
Physiology (option A) focuses on how the body's chemicals work together in living
organisms to survive. Ecology (option C) studies organisms in their environment.
Histology (option D) is the study of tissues.
