A strawberry farmer finds that, after a hard freeze, some of his strawberries are still alive. Which best explains why some of these strawberries were able to survive?

• They had larger leaves to protect the fruit than some other strawberries. 
• They have different genetic variations that cause them to be more resistant to cold temperatures.  
• They are able to reproduce more quickly than the others. 
• The color of the strawberries is darker and they maintain their temperature better than the other strawberries.

Which best describes a controversial issue associated with the use of genetically modified crops?

• the use of genetically modified crops to increase potential yield

How does biotechnology most likely affect North Carolina’s population?

• Jobs are created and attract more people to the area.

• Research advancement causes people in need of medicines to move

  to the area.

• People are not concerned with biotechnology so the overall population

  is not impacted.

• The issue causes controversy and people hesitate to live in a state

  where a large amount of research takes place.

Bacteria cells can be used to produce insulin for the treatment of diabetes in humans. Which best explains how the bacteria cells are able to produce insulin for humans?

• The bacteria have been grown on a petri dish containing insulin.

• The bacteria have been genetically engineered to contain the DNA

  needed to produce insulin.

• The bacteria have been exposed to radioactivity to create mutant

  strains capable of producing insulin.

• The bacteria have been grown on a petri dish containing sugar; the

  bacteria produce insulin in response to the sugar.

How can biotechnology affect agriculture on a single plot of land?

• The land could produce more food than before.

• The land could produce several harvests at once.

• The land could require more fertilizer for crops to grow.

• The land could require moderate temperatures for crops to grow.
