Natural Selection and Antibiotic Resistance

What is the primary target of antibiotics in the human body?

• Human cells

• Viruses

• Bacteria

• Fungi

In a habitat where lighter-colored frogs are easily seen by predators, what is likely to happen to the frog population over a long period?

• The population of lighter-colored frogs will increase.

• The population of darker-colored frogs will decrease.

• The frequency of darker-colored frogs will increase.

• All frogs will eventually become lighter-colored.

How does natural selection relate to evolution?

• Natural selection is a type of evolution.

• Natural selection is a mechanism that drives evolution.

• Evolution is a mechanism that drives natural selection.

• Natural selection and evolution are unrelated processes.

What is an important practice to help prevent the development of antibiotic resistance?

• Taking antibiotics for viral infections like the common cold.

• Stopping antibiotics as soon as symptoms improve.

• Only taking antibiotics for bacterial infections when prescribed.
