(03.08 MC) A corn plant has been genetically engineered. It produces pollen that can make its own toxins. These toxins protect the corn plant against pests. What is a likely impact on the environment around the corn plant? Bird and butterfly populations around the area may increase. The concentration of pesticides in a nearby lake would increase. Newer strains of pesticide-resistant pests may develop. The carbon dioxide level would increase in the area. Question 3(Multiple Choice Worth 3 points) (03.08 LC) Which technology has been commonly utilized by scientists to manipulate heritable information by creating DNA fragments with ends that can join with other DNA fragments? Gel electrophoresis Genetic cloning Plasmid transformation Restrictive enzyme analysis Question 4(Multiple Choice Worth 3 points) (03.08 MC) Which of the following best describes an advantage of artificial selection? Can increase the variation in a certain species Helps produce offspring having desired traits Helps produce offspring who do not suffer from diseases Can make species immune to changes in the environment Question 5(Multiple Choice Worth 3 points) (03.08 MC) Two methods of biotechnology used by scientists are described below. Method X: Used genetic engineering to create a crop of corn that grows faster and is pest resistant Method Y: Used artificial selection to create a new breed of dog that sheds less Which method is likely to be more advantageous in agriculture? Method X, because it increases the available food supply Method X, because it protects the corn from diseases Method Y, because it increases genetic diversity of dogs Method Y, because it increases biodiversity of dogs Question 6(Multiple Choice Worth 3 points) (03.08 MC) The following table describes some biotechnological processes.
