Questions and Answers

What are stem cells?

  • Cells that divide to produce specialized cells (correct)
  • Cells found only in plant stems
  • Cells that maintain the body's external environment
  • Cells with limited differentiation abilities
  • What is the main difference between embryonic stem cells and adult stem cells?

  • Adult stem cells can differentiate into any type of body cell, while embryonic stem cells have limited differentiation specific to their tissue origin
  • Embryonic stem cells can only differentiate into blood cells, while adult stem cells can differentiate into any type of body cell
  • Embryonic stem cells can differentiate into any type of body cell, while adult stem cells have limited differentiation specific to their tissue origin (correct)
  • Adult stem cells can only differentiate into blood cells, while embryonic stem cells can differentiate into any type of body cell
  • How can embryonic stem cells be recreated to avoid ethical issues?

  • By exposing the cells to extreme temperatures
  • By isolating stem cells from adult tissues
  • By replacing the egg cell's genome with an adult's genome or by introducing specific genes into an adult skin cell (correct)
  • By using a specific chemical process to alter the cell's properties
