Answer:
The gene that contains the ampicilin was really transferred from Strain II to Strain I. That can be said because in bacterias there's something called plasmid conjunction.
Explanation:
The plasmid is there to help the bacteria with its resistance, and that's how they protect themselves. This Strain can be shared from one bacteria that has the right gene to protect itself, to another one without it, but be careful, there are lots of ways that a bacteria can transfers its genes to another one, so don't stick into just one process. The most common one is conjunction, and this one is quite simple, a bacteria transfers a part of its own plasmid to another one, and through this, the process happens.
