Pesticide and Antibiotic Resistance

Which of the following best describes how natural selection results in insects that are pesticide resistant?

• When a pesticide is sprayed on a crop, a few insects survive. These insects happen to have a random mutation that makes them resistant to the pesticide. These insects survive and reproduce, eventually resulting in pesticide-resistant population.

• When a pesticide is sprayed on a crop, the insects respond by mutating their DNA, making them resistant to the pesticide. Therefore, a pesticide resistant population evolves.

• When a pesticide is sprayed on a crop, it causes mutations in the insect DNA. Some of these mutations make the insects pesticide-resistant. These insects now form a pesticide-resistant population.

• When a pesticide is sprayed on a crop, it kills the insects, which allows a new species to migrate into the habitat. Some of these species are pesticide resistant, thus a new population of pesticide resistant insects appears.

Using the diagram, which of the following best describes antibiotic resistance?

• The virus (orange) causing the sickness will survive and reproduce while taking the antibiotic

• Certain bacteria (blue) are resistant to the antibiotic.  They survive and reproduce creating a new resistant strain

• The virus (blue) causing the sickness will survive and reproduce while taking the antibiotic

• Certain bacteria (orange) are resistant to the antibiotic.  They survive and reproduce creating a new resistant strain.

After many generations, an insect species evolved resistance to a particular pesticide. This occurred because spraying the pesticide...

• killed most of the insects in the population

• caused another inspect species to go extinct

• caused mutations in the insect species’ gene pool

• selected for insects that were able to survive and reproduce

What is the primary mechanism by which bacteria develop antibiotic resistance?

• Natural selection of resistant strains

• Bacteria intentionally mutate to resist antibiotics

• Antibiotics cause mutations in bacteria

• Bacteria acquire resistance from the environment

How can the overuse of antibiotics in agriculture contribute to antibiotic resistance?

• It kills all bacteria, leaving none to develop resistance

• It promotes the growth of resistant bacteria

• It has no effect on bacterial resistance

• It only affects human bacteria

What role do plasmids play in antibiotic resistance?

• They carry resistance genes between bacteria

• They destroy antibiotics

• They make bacteria more susceptible to antibiotics

• They have no role in resistance

Which of the following is a consequence of pesticide resistance in agriculture?

• Increased crop yield

• Decreased biodiversity

• Improved pest control

• Reduced pesticide use

• Rotating different types of pesticides

• Increasing pesticide concentration

• Reducing pesticide application

How does horizontal gene transfer contribute to antibiotic resistance?

• It allows bacteria to share resistance genes

• It prevents bacteria from acquiring resistance

• It only occurs in laboratory settings

• It is unrelated to antibiotic resistance
