What role does a morphogen gradient play in development?

1. It controls metabolic processes
2. It provides positional information for cells to differentiate
3. It regulates the circulatory system
4. It determines the color of an organism

What are stem cells?

1. Cells that are only present in the human body.
2. Cells found only in plants and fungi.
3. Cells that can only develop into blood cells.
4. Undifferentiated cells that can develop into specialized cells.

Where can stem cells be found?

1. Only in adult humans.
2. Exclusively in the brain.
