In a nutshell, a chemical change produces a new substance, while a physical change does not. A material may change shapes or forms while undergoing a physical change, but no chemical reactions occur and no new compounds are produced. And for an explanation on how to see the difference Look for an indication that a chemical change occurred. Chemical reactions release or absorb heat or other energy or may produce a gas, odor, color or sound. If you don't see any of these indications, a physical change likely occurred. Be aware a physical change may produce a dramatic change in the appearance of a substance. This doesn't mean a chemical reaction occurred.

Lately the greenhouse effect has been magnified due to greenhouse gases emitted into the atmosphere by humans. and global warming is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.Global warming refers to the increase in annual average temperatures across the globe. As the amount of greenhouse gases in the atmosphere increases, the planet becomes warmer and warmer on average.

Allisa [31]

Answer:

If they didn't differentiate then the stem cells would stay the same type and if it somehow kept multiplying then they would just be a massive blob with no actual form or way of functioning.
