In a toy, two men with red and blue caps are moving in two different circular paths of same radii. When the man with red cap moves 3 steps, the one with blue cap moves 5 steps in the same time, but the distance traversed by the man with red cap in 5 steps, is equal to the distance traversed by the man with blue cap in 4 steps. What is the number of rounds the man with red cap made the man with blue cap completed 100 rounds?

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?
