Bioremediation

When using bioremediation to clean up toxic contaminated soil, what happens to the bacteria when the pollutants are cleaned up?

• The area is treated with antibiotics.
• The area is treated with concentrated oxygen.
• The bacteria run out of food and die off naturally.
• The bacteria are covered with fresh soil and they die due to a lack of oxygen.

Oil released into the environment is a well-recognized problem in today's world. What famous oil spill led to today's biodegradation of oil?

• Wesson oil spill
• Exxon Valdez spill
• Canola oil spill
• The sinking of the Titanic

Bioremediation uses toxin-degrading bacteria to clean up:

• Gold and silver.
• Hazardous material.
• Dirty instruments.
• Viral infections.

Doctors use biosensors in the medical field to test for:

• Mental illness.
• Headaches.
• Strep throat.
• Fractures.

When using biosensors to fight pollution, the biosensor is helpful in telling us:

• What caused the pollution.
• How long the pollution has been present.
• Who is responsible for the pollution.
• Where and what the pollution is.

* In the biodegradation of oil by aerobic bacteria experiment, why were aquarium pumps used to pump air into the soil sample?

• Because the air keeps the soil from turning to mud.
• Because the air keeps the soil dry.
• Because the air provides the oxygen bacteria need to survive.
• To minimize the foul odor created by the soil.
