Question 23

A toxin destroys one type of specialised cell in each of two organs, P and Q, of an adult mouse. The other types of cell in each organ survive.

Several weeks later, the destroyed cells have been replaced in organ Q but not in organ P.

Using your knowledge of cell differentiation, explain the different outcomes in organs P and Q.
