Using a high nitrogen fertilzer.
Using herbicide to get rid of weeds.
Genetic modification of rice plants that are pest resistant and to produce vitamins they cannot make without biotechnology

In the United States, there has been relatively little experimentation involving the insertion of genes from other species into human DNA. What is one reason for the limitations of these experiments?
The subunits of human DNA are different from the DNA subunits of other species.
Inserting foreign DNA into human DNA would require using completely new techniques.
Human DNA always promotes human survival, so there is no need to insert foreign genes into it.
There are many ethical questions to be answered before inserting foreign genes into human DNA.
Many species of bacteria have become resistant to antibiotics because antibiotics have been so widely used. Now, bacteria that used to be killed by antibiotics are more difficult to treat. What is the best way to proceed in dealing with this public health problem?
Antibiotics should no longer be used.
Antibiotics should be made available to anyone without a prescription.
Antibiotics should only be prescribed to people with bacterial infections
Anti-viral medications should now be used instead of antibiotics.
Scientists have inserted a gene that codes for resistance to a biodegradable weedkiller into a certain plant. Which of the following is most likely to occur when this gene is inserted?
The plant will become able to produce chemicals to kill weeds around it.
The plant will become able to produce chemicals to kill weeds around it.
The plant will become able to convert the weedkiller into fertilizer.
The plant is more likely to survive when exposed to the weedkiller.
What prevents scientists from cloning humans despite the fact that other mammals such as sheep have been cloned?
Cloning humans would take too much time to reproduce.
There are many ethical problems involved in cloning humans.
The technology to clone humans has not been explored.
Human reproduction is very different from that of other mammals.
GMO crops are regularly met with opposition, Golden Rice is grown and distributed in regions where rice consumption is high and variety in diet is low. Which of the following explains a benefit of using Golden rice in these areas?
Golden Rice is bio-engineered and is yellow as a result.
Golden Rice allows regions with a low variety of food to receive necessary nutrients.
Beta-carotene is a lab-created nutrient that has unknown effects.
Producing Golden Rice will result less variety of food grown.
