Which of the following statements about totipotent cells is correct?
They can differentiate into all cell types of an organism, including extraembryonic tissues.
Which of the following cell types is derived from the mesoderm germ layer?
Muscle cells
Which of the following statements about embryonic stem cells (ESCs) is correct?
ESCs are pluripotent, meaning they can differentiate into all cell types except extraembryonic tissues.
