Bioremediation Correct Answers Introduction of microbes into
the environment to restore stability or to clean up toxic
pollutants
Biotechnology Correct Answers Manipulation of
microorganisms to make products in an industrial setting
Can a medium be classified as both selective and differential?
Correct Answers Yes, some media can be both selective and
differential
, Can antibiotics target viral infections? Explain your answer.
Correct Answers No, because:
• Viruses mutate at a rapid rate
