Where do scientists obtain adult stem cells?<br> saliva<br> pancreas<br> skin<br> bone marrow
Alex17521 [72]
<span> Embryonic stem cell research is kind of a dead area now since there is no way to control the differentiation. Most research is being done on adult stem cells to help map and control the differentiation process.

Stem-cells from aborted fetuses - The government doesn't sponsor this, if it is done it is by private companies not located in the USA. You could try researching umbilical cord stem cells to be somewhere near your topic. They come from the afterbirth of normal deliveries.

What feature of alcohol fermentation makes it more suitable for the baking process than lactic acid fermentation?

Alcohol fermentation produces carbon dioxide gas as a by-product, and this is why alcohol fermentation is more suitable for baking. Alcohol fermentation occurs when breads are made. The carbon dioxide gas is what creates tiny air bubbles within the dough and makes bread be the light consistency we are used to. In contrast, bread made without yeast (alcohol fermentation) is very flat.
