A scientist constructs a recombinant bacterial plasmid that contains a gene conferring resistance to the antibiotic ampicillin (amp). The scientist transforms cultures of E. coli bacteria with the recombinant plasmid, then incubates the cultures overnight on plates containing media without ampicillin (amp-) and with ampicillin (amp+).

Assuming the transformation protocol was successful, which of the following best predicts the bacterial growth pattern expected after the incubation period?
