Final answer:
Embryonic stem cells can give rise to any type of cell, while adult stem cells can give rise to a subset of cell types.
Step-by-step explanation:
Embryonic stem cells can give rise to any type of cell, while adult stem cells can give rise to a subset of cell types.
For example, embryonic stem cells have the potential to differentiate into nerve cells, muscle cells, epithelial cells, and more. On the other hand, adult stem cells are more limited in their potential and can differentiate only into specific types of cells, such as blood cells, muscle cells, or skin cells.
Therefore, option 2) Embryonic stem cells; adult stem cells is the correct answer.
