Questions and Answers

What does the process of differentiation determine in a cell?

  • The color of the cell
  • The size of the cell
  • The taste of the cell
  • Whether it will spend its life as a nerve cell or a muscle cell (correct)

How is cell differentiation controlled in mammals like humans?

  • By the level of noise in the environment
  • By the moon phases
  • By external temperature
  • By a number of interacting factors in the embryo (correct)

At what point do adult cells generally reach complete differentiation?

  • When they become stem cells
  • When they start dividing rapidly
  • When they can change color
  • When they can no longer become other types of cells (correct)
