Question 2
What happens when a piece of tissue kept for a long time in a freezer is suitably grafted into another organism?
The right answer is the one marked above.
Its living characteristics can be observed once again. The characteristic had been out of sight, but it had not been lost.
If the tissue can show living characteristics again it cannot be something that was never alive. Grafting does not turn it into non-living material, and no new species is formed.
