- Skin cells are specialized cells that have undergone terminal differentiation.

2. **What cell type undergoes terminal differentiation?**
- **B. Heart cells** (Correct)
- Heart cells (cardiomyocytes) are terminally differentiated cells that do not typically divide further.

3. **In eukaryotic cells, DNA replicates in the**
- **D. Nucleus** (Correct)
- DNA replication occurs within the nucleus of eukaryotic cells.

4. **Which of the following is a function of mitosis?**
- **D. To repair damaged tissue** (Correct)
- Mitosis is crucial for cell division and tissue repair.

5. **What replicates during mitosis?**
- **B. Cells** (Correct)
- Mitosis is the process where one cell divides to produce two daughter cells.
