you test a strain of bacteria, strain x with an antibiotic and all of the bacteria are killed. overnight there is an accident and your bacteria strain is
mixed with another strain, strain y, known to be antibiotic resistant. you separate them out again and perform the same antibiotic test on strain
x again, but this time a few survive. what probably happened?

•
a. bacteria can't transfer anything to each other, it was a coincidence.
b. mixing with the other strain dissolved the capsule on some of the bacteria, allowing them to survive.
c. when they mixed, some of the bacteria from strain x obtained plasmids from strain y, these plasmids gave them dna that allowed
them to resist the antibiotic.
d. some of the bacteria from strain x engulfed the strain y bacteria, taking their resistance to antibiotics
