o
b. no living tissue is damaged when scientists use embryonic stem

o
c. there is no controversy surrounding the use of embryonic stem

d. Embryonic stem cells are able to differentiate into a wider range of  cells than adult stem cells.

Explanation:

Embryonic stem cells has the capability to make any cell in the body because of pluripotent. Adult stem cells can divide but not at the same frequency as the embryonic stem cells do. Embryonic stem cells can be easily cultured. But when it comes to adult stem cells its cultured is quite difficult and not yet tried. The adult stem cells are likely to be banned being transplantation. The adult stem cell will not be dismissed by the immune system of the person if the stem cells are from same person.

a- multicellular
