Question
Put the following steps in the evolution of antibiotic resistance in the order in which they occur:
The antibiotic is more-or-less obsolete (useless, ineffective).
Selection favors compensatory mutations in the Ab-resistant population to favor the evolution of higher growth rates.
An advantageous mutation occurs that does not influence Ab-resistance, but increases growth rate.
The individual cell with the Ab-resistant allele survives and reproduces slowly.
Antibiotics are introduced into the environment.
A deleterious mutation occurs in a single cell that confers antibiotic resistance but compromises growth rate.
The antibiotic is more-or-less obsolete (useless, ineffective).
Selection favors compensatory mutations in the Ab-resistant population to favor the evolution of higher growth rates.

Explanation / Answer
Antibiotics are introduced into the environment.
A deleterious mutation occurs in a single cell that confers antibiotic resistance but compromises growth rate.
The individual cell with the Ab-resistant allele survives and reproduces slowly.
