Consider the three different types of stem cells. Each one’s ability to differentiate into new cells is slightly different. One type can differentiate into any cell, while another can only become specific cells. Select the answer that places the three types in the correct order, from widest range of differentiation to least able to differentiate (specific).(1 point)

When a stem cell differentiates and changes in size and shape, specific genes are being **expressed**.
Answered by

The correct answer is **senescence**. This term describes when a cell leaves the cell cycle and no longer divides.

The correct order from widest range of differentiation to least able to differentiate (specific) is **totipotent, pluripotent, multipotent**.
- **Totipotent** stem cells can differentiate into any cell type, including the extraembryonic tissues.
- **Pluripotent** stem cells can differentiate into nearly any cell type but not extraembryonic tissues.
- **Multipotent** stem cells can only differentiate into a limited range of cells, usually within a specific tissue or organ type.
- **Totipotent** stem cells can differentiate into any cell type, including the extraembryonic tissues.
- **Pluripotent** stem cells can differentiate into nearly any cell type but not extraembryonic tissues.
- **Multipotent** stem cells can only differentiate into a limited range of cells, usually within a specific tissue or organ type.

The correct response is **chemicals in the body**. Gene expression can be influenced by various biochemical signals and environmental factors, including hormones, nutrients, and other chemicals present in the body.

The correct response is **temperature of the water**. Environmental factors, such as temperature, can affect gene expression by influencing the biological processes in an organism.
