Stem cells have the capacity to regenerate, and some can even regenerate into almost any type of cell. Stem cell research is a relatively new science that can be used to recreate organs such as livers or that would give many terminally ill people a chance to survive. What is one disadvantage of stem cell research?
A. The long-term effects of stem cells are completely unknown.
B. Invasive surgery is required to extract organs grown with stem cells.
C. We cannot control which organs stem cells will develop into.
D. Stem cells have no practical application to regenerative medicine.

My guess would be A. B isnt right because you dont need a whole organ to grow an organ, but just a few of its cells. C isnt good either because you can control what stem cells will develop into by taking a cell from whatever is need, and d just doesnt make sense to me.

Stem cells have the ability to become other cells and also tissues. These functions occur after cell division after a long period of. Research has been done to determine the effect of stem cells. Stems have not been used for a long period of time for research to determine what will happen after a long period of time and to analyze it. The disadvantage is long-term effect of the stems being completely unknown. Once trials have been demonstrated for the stems for a long period of time, this disadvantage will be erased.
