,1. Multiple Choice: Which of the following is a reversible cellular
adaptation?
A) Atrophy
B) Hypertrophy
C) Metaplasia
D) Dysplasia
Correct Answer: B) Hypertrophy
Rationale: Hypertrophy is an increase in cell size that occurs in
response to a demand for increased function, and it is reversible if
the stimulus is removed.
2. Fill-in-the-Blank: __________ is the decrease in cell size due to
reduced functional demand or adverse environmental conditions.
Correct Answer: Atrophy
Rationale: Atrophy is the process where cells shrink and reduce
their differentiated functions in response to normal and injurious
factors.
3. True/False: Hyperplasia is the increase in the number of cells in
an organ or tissue.
Correct Answer: True

, Rationale: Hyperplasia is a cellular adaptation that involves an
increase in the number of cells, often as a response to increased
physiological demands or hormonal stimulation.
4. Multiple Response: Select all that apply. Which of the following
are types of cellular adaptation?
A) Anaplasia
B) Hyperplasia
C) Neoplasia
D) Hypertrophy
Correct Answers: B) Hyperplasia, D) Hypertrophy
Rationale: Hyperplasia and hypertrophy are both adaptive
mechanisms that enable cells and organs to adjust to changes in
their environment.
5. Multiple Choice: Apoptosis is best described as:
A) Programmed cell death
B) Necrosis
C) Autophagy
D) Oncosis
Correct Answer: A) Programmed cell death
