Objective 5.02 Agriscience

Genetic engineering has been used to develop bacteria strains to convert solid waste
from humans and livestock into:
1. Paper and tissue.
2. Salt and pepper.
3. Sugar and fuel.
4. Wood and fiber.
Permeability is the rate of movement of what through the soil?
1. Air and fertilizer
2. Water and Air
3. Water and fertilizer
4. Water and microorganisms
Bacteria that are attracted to oil and are used to clean up oil spills are called:
1. bio-indicators.
2. oleophilic.
3. algae.
4. lichens.
If a site had been polluted by industrial chemicals, and trees were planted to absorb the
chemicals, the technique used is called:
1. genetic engineering.
2. biostimulation.
3. oleophilic.
4. phytoremediation.
One of the limitations of bioremediation, as compared to the use of chemical techniques
is:
1. emissions.
2. space
3. time.
4. oil.
What technique was used to cleanup the Exxon Valdeze oil spill?
1. Bioremediation.
2. Indicator species.
3. Phytoremediaton.
4. Genetic engineering.
If the air is badly polluted with sulfur dioxide, a widely used indicator species is used to
detect it. That bio-indicator is:
1. E. coli.
2. bacteria.
3. lichens.
4. viruses.
