C. producing an enzyme that metabolizes the antibiotic

D. all of the answers are correct

3. Antimicrobials that are effective against a wide variety of microbial types are termed

A. antibiotics

B. narrow-spectrum drugs

D. synthetic drugs

E. broad-spectrum drugs

Solutions

Expert Solution

1. C. is static.

Bacteriostatic antibiotics cause the inhibition of the bacteria and do not kills them. This gives them the chance to mutate and causes resistant strains leading to superinfection.

2. Acquired resistance of antibiotics occurs when a type of bacteria changes in a way that protects it from the antibiotic. This can occur through a new genetic change called mutation that helps the bacterium survive.

3. E. broad-spectrum drugs

broad-spectrum antibiotics are effective against a broad range of bacteria or microbes like ampicillin, tetracyclines etc.

1. Allopatric speciation is most likely to occur in which of the following scenarios? Group of answer choices There are two distinct possible feeding strategies within a given population, causing the rise of two species living in the same geographic area. All of the “parent” species of a new species go extinct, reducing gene flow between populations. A mutation changes the mating ritual followed by a subset of individuals in a population, and they end up forming an all-new species....
