Medical professionals are concerned with the increase in the number of bacterial species that are resistant to antibiotics. Once resistance appears in a bacterial population, it spreads rapidly. This is most likely because (1) populations of resistant bacteria are small (2) exposure to antibiotics increases the rate of reproduction in bacteria (3) resistant bacteria are small when compared to non-resistant bacteria. (4) resistant bacteria survive in greater numbers and pass the trait to their offspring
