Embryonic stem cells are cells derived from an embryo. these cells can be used to create new tissues for patients suffering from certain illnesses and disorders. which statement best summarizes why the use of embryonic stem cells could be seen as unethical?
a.
some people consider embryos to possess rights equal to those of fully developed human beings.
b.
extracting stem cells from embryos is a very energy-intensive process, which consumes resources that could be used elsewhere.
c.
embryos are difficult to obtain, so the monetary cost of using them for research outweighs their benefit.
d.
the process of extracting stem cells from embryos generates biohazardous waste that cannot be safely disposed of.

Option A, Some people consider embryos to possess rights equal to those of fully developed human beings.

Explanation:

When stem cells are derived from embryo, the embryo dies in lieu to end of its cell development and this happens because stem cells are the only cells that have potential to develop an embryo by producing more stem cells and differentiating them into specific organs.

In most of the study, embryonic stem cells are derived from embryos that are obtained from IVF technique as an spare embryo. But this act is considered unethical as embryos have life within them and hence they also have rights equal to a fully developed human being.

Hence, option A is correct.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
