Question

why is adult stem cell research less controversial than embryonic stem cell research?
a) consent can be obtained from adult stem cell donors.
b) donated cadavers can be used to harvest adult stem cells.
c) stem cells from adults require no animal experimentation.
d) adult stem cell research has wider medical applications.

Explanation:

Embryonic stem cell research is controversial because it involves the destruction of embryos. In contrast, adult stem cells can be obtained from consenting donors (such as bone marrow donations from adults). Consent is a key ethical consideration. Option B about cadavers is not the main reason for less controversy compared to the consent aspect. Option C is incorrect as stem cell research (including adult) may still involve some animal - related work in pre - clinical stages. Option D is not the reason for the difference in controversy levels.

Answer:

A. Consent can be obtained from adult stem cell donors.
