Which of the following statements does not accurately describe stem cells?
a. the use of stem cells is without any objections since it can be used in therapies to humans.
b. adult stem cells are multipotent and can differentiate into many types of cells.
c. the use of stem cells may allow scientists to use undifferentiated cells to repair or replace bad cells.
d. embryonic stem cells make up the inner cell mass of a blastocyst.

B. Adult stem cells are multipotent and can differentiate into many types of cells.


Stem cells begin to transfor into different types of cells in the human body in a process known as cell differentiation.

Cellular differentiation occurs throughout the cell development of a multi-cellular organism. It occurs when the cell changes from a simply zygote into a complex system of tissues and cell types. 

Stems cells are cells which have the potential to develop into many different cell types in the body during early life and growth. Stem cells serve as internal repair system in many tissues. When stem cells divide while undergoing cell differentiation, it can either retain being a stem cell or become another type of cell like muscle cell, brain cell, or red blood cell. 

The correct answer:   [c]:   "cell phone call" .
