, Expert-Verified Explanations
### 1. (True/False) – Make true if False
Cell proliferation is the process in which proliferating cells become
more specialized cell types.
Correct Answer: False; the process described is cell differentiation.
Verified Explanation: Cell proliferation involves increasing cell number
through mitosis. Cell differentiation refers to the process by which cells
become structurally and functionally specialized.
---
### 2. (True/False) – Make true if False
Cell differentiation is the process of increasing cell numbers by
mitotic cell division.
Correct Answer: False; the process described is cell proliferation.
Verified Explanation: Differentiation is the process wherein cells become
specialized; proliferation pertains specifically to cell division and the
augmentation of cell numbers.

### 3. (Short answer) What are two important properties that stem
cells possess?
Correct Answer: Potency and self-renewal.
Verified Explanation: Potency refers to the stem cell's ability to
, differentiate into various specialized cell types, while self-renewal is the
property that allows the stem cell population to be maintained through many
cycles of cell division.
### 4. (True/False) Metaplastic cells are not better prepared to
survive under stressful circumstances.
Correct Answer: False
Verified Explanation: Metaplastic cells arise through the process of
metaplasia, whereby one differentiated cell type is replaced by another cell
type better suited for survival under adverse conditions. This adaptation
increases the survival capacity of tissues exposed to chronic stressors or
irritants, such as in the replacement of ciliated columnar cells in the airways
with squamous epithelium in smokers.
---
### 5. (True/False) Hypertrophy can occur under normal and
pathological conditions.
Correct Answer: True
Verified Explanation: Hypertrophy describes the increase in cell size,
which contributes to organ enlargement. This process can occur in response
to physiological stimuli, such as increased workload in muscle after exercise,
or pathological stimuli, such as cardiac hypertrophy secondary to
hypertension.

### 6. Which are true of the mitochondria? (select all that apply)
- It is involved in cellular respiration
