What are two ethical problems with stem cell research?
This is not a question that can be answered with a simple 'yes' or 'no'. Embryonic stem cell research has the potential to cure a range of degenerative disorders from Alzheimer's to ALS, as well as supply organ transplants without the risk of immune rejection. To harvest functional stem cells, they must be extracted from a fertilized egg before the cells differentiate, or 12-14 days maximum. Fertilized eggs from in vitro fertilization clinics have been used only after fertilization attempts have ended. These fertilized eggs are notguaranteed to implant or be able to develop into a baby, and neither of these if a prerequisite for harvesting ES cells. Only 24% of attempted IVF pregnancies yielded a live and healthy baby in 2005 (mdwebsite.com). On the one hand, these fertilized eggs will never be used for anything yet hold such a promising therapy for so many individuals alive today. The ethical parallel for this situation is, "is it ethically wrong to use functional organs as transplants from a deceased individual, or wouldn't it be a waste?" On the other hand, we realize that society has created these fertilized eggs, and a small percentage of them have the potential to develop into healthy babies if given to correct situation. ES harvesting as of yet, does not differentiate between these two, and must destroy the embryo in order to retrieve the ES cells. This is destroying the potentialfor life in certain embryos. Though they are not alive yet, they do contain the ability to develop into an organism, a human, and they were intentionally created to do just that. In regards to were the promise and statistics lie, it seems unethical to allow an intentionally manufactured collection of multipotent cells to go to waste when so many people in pain and nearing pre-mature death could benefit from them.This is true but one fact always seems to be overloooked. An embryo is not the only place that stem cells can be taken from. Umbilical cord stem cells have the capability of changing into almost just as many cells as embryonic stem cells. Just a few weeks ago an autstic boy was cured with umbilical cord stem cells.

Liver cells
Which cells might not contain any chlorplasts?
Animal cells,prokariyotic cells,protozoans and fungi do not have.They are in plant and algal cells.
Explain why stem cells can duplicate whereas cheek cells can't?
Stem cells have the unique ability to self-renew and differentiate into different cell types because they are undifferentiated and have the potential to become specialized cells. Cheek cells, on the other hand, are already differentiated cells that have already reached their specialized state and do not have the capacity for self-renewal or differentiation.
In addition to a cell membrane what other cell boundary might some cells such as plant cells have?
Plasma
Does your body have 75 cells?
Your body might develop 75 cells while you are as an embryo. People have billions-trillions cells.

Why are religious people against DNA testing?
Some are, some are not. Don't lump them all together.Those that ARE against DNA testing might have a general mistrust of newfangled science, or might think that it is interfering in God's business.
Which cells might be used in laboratory to make heart cells?
Liver cells
Who is against Labor Day?
Labor Day was first celebrated by a workers union so anyone who is against organized labor might be "against" Labor Day. In general, not many people are against a day off of work.
