– 2027 VERSION SOLVED QUESTIONS & ANSWERS
Q1. Which level of structural organization is the simplest, consisting of atoms and
molecules?
A. Organ level
B. Cellular level
C. Chemical level
D. Tissue level
Correct Answer: C
Rationale: The chemical level is the simplest level of organization and includes atoms
and molecules.
Q2. The diaphragm separates which two body cavities?
A. Cranial and spinal
B. Thoracic and abdominal
C. Pelvic and abdominal
D. Pleural and pericardial
Correct Answer: B
, Page 2 of 73
Rationale: The diaphragm is a muscular structure that separates the thoracic cavity
from the abdominal cavity.
Q3. Which type of feedback mechanism amplifies or enhances the original
stimulus?
A. Negative feedback
B. Neutral feedback
C. Positive feedback
D. Receptor feedback
Correct Answer: C
Rationale: Positive feedback amplifies the change that is occurring, such as in
childbirth or blood clotting.
Q4. If a scientist forms and tests a hypothesis but gets unexpected results, what is
a logical next step? (Select all that apply.)
A. Accept the original hypothesis
B. Reject the original hypothesis
C. Revise the original hypothesis
D. Design a new experiment based on a new or modified hypothesis
Correct Answer: B, C, D
Rationale: Unexpected results require rejecting or revising the hypothesis and designing
new experiments based on the modified hypothesis.
Q5. Anatomy is best defined as the study of:
A. How body structures function.
B. The structure of body parts and their relationships.
, Page 3 of 73
C. The chemical processes within cells.
D. The classification of diseases.
Correct Answer: B
Rationale: Anatomy focuses on the structure of body parts and their spatial
relationships, while physiology studies function.
Q6. Physiology is best defined as the study of:
A. The structure of body parts.
B. How body structures function.
C. The classification of organisms.
D. The microscopic structure of tissues.
Correct Answer: B
Rationale: Physiology is the study of the function of body structures and the processes
that sustain life.
Q7. Which level of organization consists of groups of similar cells that perform a
common function?
A. Chemical level
B. Cellular level
C. Tissue level
D. Organ level
Correct Answer: C
Rationale: The tissue level consists of groups of similar cells with a common function.
Q8. The principle that structure determines function is known as:
A. Homeostasis
, Page 4 of 73
B. The principle of complementarity
C. Negative feedback
D. Anatomical position
Correct Answer: B
Rationale: The principle of complementarity states that structure and function are
inseparable and that structure determines function.
Q9. Which body cavity contains the heart and lungs?
A. Abdominal cavity
B. Pelvic cavity
C. Thoracic cavity
D. Cranial cavity
Correct Answer: C
Rationale: The thoracic cavity contains the heart, lungs, and other thoracic organs.
Q10. The term "homeostasis" refers to:
A. The constant changing of internal conditions.
B. The maintenance of a relatively stable internal environment.
C. The process of cell division.
D. The study of body structure.
Correct Answer: B
Rationale: Homeostasis is the ability of the body to maintain a relatively stable internal
environment despite external changes.
Q11. Which of the following is an example of a negative feedback mechanism?
A. Uterine contractions during childbirth
