This science allows us to alter the DNA of an orange tree so the fruit contains more vitamin C.

• Physical science
• Biotechnology
• Biology
• Geology

Which of the below is an ethical issue in the field biotechnology?

• Outrageous cost - very expensive
• We can live longer and healthier lives
• Sometimes the harm outweighs the good
• Public opinion of the technology

Which of the below biotechnological advances is MOST beneficial to Florida FARMERS?

• Development of disease resistant plants for higher yields
• Development of more effective human vaccines
• The ability to create more antibiotics from bacteria
• Producing enzymes to eliminate pollutants

While genetic engineering has positive benefits, there are also concerns associated with widespread use of genetic engineering in agriculture. If many farmers begin to plant more genetically modified crops that have an increased tolerance to insects, which of the following may result? 

• an increase in the use of pesticides
• a decrease in genetic diversity of the crops
• an increase in the contamination of the water supply
• a decrease in crop productivity

Stem cell research has been a controversial subject in past years. What is the reason for this? 

• Cells for study are often taken from human embryos.
• Stem cell techniques will not accomplish the intended purpose.
• The cells cannot be isolated.
• Replacement tissue will never be grown from a person's own stem cells.

What kind of genetically modified crops would be most successful in wet-tropical countries that are overcrowded? 

• crops that are drought- and pest-resistant
• high-yield crops that do not need a lot of sunshine
• high-yield crops that are pest-resistant
• crops that are drought-resistant and need a lot of sunshine

In what way did gene therapy, the replacement of a faulty gene with a normal one, stimulate medical research? 

• New medications had to be developed and tested.
• The effects of viral DNA had to be studied.
• The way in which DNA replicates had to be determined.
• The genes on each chromosome had to be mapped and described.
