Module 8 Exam Review

genetically modified foods have had their DNA changed through genetic engineering. Which statement is a logical argument in support of genetically-modified foods?

• genetically modified varieties of plants produce lower crop yields than normal plants

• food safety regulators are developing guidelines for labeling genetically modified foods

• there is enough food in the world, so its not worth the risk to use genetically modified foods

• genetically modified crops resist frost damage preventing farmers from losing money and ensuring a plentiful supply

scientists have developed cold-resistant plants by introducing the gene from cold-water fish that keeps them from freezing. these genetically modified plants are able to tolerate cold temperatures.

which statement is the most logical argument in favor of the development of such genetically modified plants?

• it reduces the causes of pest infection in plants

• it increases the nutritional value of the plant products

• it allow the plants to be grown in a wider variety of environments

• it ensures that the plants can be grown without fertilizers
