differentiation
Answered by adaleta
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)

Answered by GPT-4o mini
When a stem cell differentiates and changes in size and shape, specific genes are being **expressed**.

So the correct response is "expressed."
Answered by GPT-4o mini
The term that describes when a cell leaves the cell cycle and no longer divides is **senescence**.

So the correct response is "senescence."
Answered by GPT-4o mini
The correct order, from the widest range of differentiation to the least able to differentiate (specific), is:

**totipotent, pluripotent, multipotent.**

So the correct response is "totipotent, pluripotent, multipotent."
Answered by GPT-4o mini
Gene expression is determined by several factors, including **chemicals in the body**.

So the correct response is "chemicals in the body."

The environmental factor that could affect gene expression is **temperature of the water**.

So the correct response is "temperature of the water."
