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
