Question 3

The first agricultural species to be altered by genetic modification was the __________. A. watermelon B. squash C. soybean D. tomato Please select the best answer from the choices provided.

Revolt · Accepted Answer

D

Question 4

Using complete sentences, compare and contrast organic farming with the genetic modification of food.

Revolt · Accepted Answer

Responses may vary but should include some or all of the following information: Both methods seek to improve food quality, reduce the use of pesticides and herbicides, and reduce the environmental impact of farming. However, organic farming takes a very natural approach, while genetic modification take the opposite approach. Organic farming encourages the use of natural selection to improve food quality, while genetic modification directly manipulates DNA to alter food quality.

Question 5

Which of the following is not an advantage of genetically modified (GM) foods? A. They are sometimes more flavorful than non-GM foods. B. They can be more resistant to pests than non-GM foods. C. They can have a longer shelf life than non-GM foods. D. They can be more expensive than non-GM foods. Please select the best answer from the choices provided.

D

Question 6

As of 2010, the most prevalent genetically modified crop grown was __________. A. insect-resistant corn B. insect-resistant cotton C. herbicide-resistant cotton D. herbicide-resistant soybeans Please select the best answer from the choices provided.

Revolt · Accepted Answer

D

Question 7

What labels appear on organic food?

Revolt · Accepted Answer

Responses may vary but should include some or all of the following information: The USDA has developed two different labels. The “USDA Organic” label means that the food is produced and processed according to USDA standards and that at least 95% of the ingredients are organic. The “100% Organic” label means that the food is completely organic.

Question 8

What have studies shown regarding the safety of organically grown food?

Revolt · Accepted Answer

Responses may vary but should include some or all of the following information: Studies have not proven organically grown foods to be any more or less safe than conventionally grown foods.

Question 9

Using complete sentences, compare conventional farming with organic farming.

Revolt · Accepted Answer

Responses may vary but should include some or all of the following information: Conventional farming includes the use of chemical fertilizers, pesticides, and herbicides to increase food production and quality. Organic farming avoids the use of these agents in favor of natural practices like natural fertilizers, the use of insects and birds to reduce pests, and the use of crop rotation and mulch to maintain soil quality.

Question 10

Using complete sentences, discuss some of the potential risks of bioengineered food.

Revolt · Accepted Answer

Responses may vary but should include some or all of the following information: There is much disagreement over potential risks of bioengineered foods. Because they were developed recently, we have limited evidence to support both their benefits and risk profiles. Some people are concerned that modified plants may have harmful characteristics. Others are concerned that modified plants may breed with native species and produce unexpected results or permanently alter the ecosystem. Increased resistance to some pests may result in selective breeding of stronger pests. Also, there is concern that GM foods may cause increased allergic reactions in some consumers.
