Environmental Biotechnology

If someone invents a product of biotechnology and the product has the symbol � after the name, what does the symbol mean?

• The product contains radium.
• The product is in a remediation phase.
• The project was rushed to market and therefore is not recommended for human use.
• The name of the product is a registered trademark

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.

What statement about genes is TRUE?

• Nearly identical genes are found in a wide variety of organisms.
• Genes are only found in humans.
• Genes are found in all living organisms, but humans do not share genes with other organisms
• Genes in all mammals are identical

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.
