Briefly explain why it was important for Frederick
Griffith to use a IIIS strain in his experiments rather than a IIS
strain and what result he was able to rule out as a possible
explanation for the killing of the mouse after incubation of the
heat killed IIIS strain with living IIR that he would not have been
able to rule out if he used a IIS instead of IIIS.
