Answer
This statement is true. Adult stem cells, also known as somatic stem cells, are undifferentiated cells found throughout the body after development. They can differentiate into various cell types.

Answer
This statement is false. Stem cells are typically derived from blastocysts, which contain around 100-150 cells, rather than from a 2 or 4 cell embryo.
Step 4
D. can differentiate into a limited number of cell types.

Answer
This statement is true for adult stem cells. Unlike embryonic stem cells, which are pluripotent and can differentiate into almost any cell type, adult stem cells are multipotent and can differentiate into a limited range of cells.
