Biotechnology

What is involved in creating genetically modified bacteria? 

• allowing them to reproduce freely 
• allowing them to reproduce freely 
• using biotechnology techniques 
• growing them on selected plants 

Which of these careers would a student studying biotechnology most likely pursue? 

• electrical engineering 
• astronomy 
• agricultural research 
• geology 

Which is a way the agricultural biotechnology industry could have a positive impact on the environment? 

• by producing crops that are virus resistant
• by reducing the need for countries to import food 
• by making robots to replace large farm machines
• by increasing the use of wind farms that produce electricity 

Which project is most likely to interest a scientist working at a biotechnology company?

• study and reconstruction of fossilized bones
• conservation of key species within ecosystems
• prevention of sewage leaking into water supplies
• development of genetically modified corn plants

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. 

Farmers use insecticides and fertilizers on their fruit and vegetable crops. Which best describes the effect of these chemicals?

• The crops require less water and nutrients to grow.

• The crops are more susceptible to insect damage.

• The crops yield smaller fruits and vegetables.

• The crops yield more fruits and vegetables.

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

• the use of genetically modified crops to increase potential yield

• the short-term use of genetically modified crops in famine-stricken

  countries

• the development of genetically modified crops which are resistant to

  herbicides

• the long-term effects which may arise from the use of genetically

  modified crops

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.

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.

Which is an application of genetic engineering?

• destroying all bacteria

• creating synthetic insulin

• producing cells from nonliving material

• preventing weeds from spreading to farmland
