Question
Which type of biotechnology is used by scientists when they alter the DNA of a plant to make it grow faster?
Group of answer choices
Genetic engineering because the genes of the plants were modified
Genetic engineering because it is always helpful to society
Artificial selection because it always produces desirable traits
Artificial selection because the DNA of the plant was changed

A genetically engineered corn plant is approved for agricultural use. The plant produces pollen that can make its own toxins. These toxins protect the corn plant against pests and no longer require the application of chemical pesticide. What is a likely impact on the farmer of growing such a variety of corn?
Group of answer choices
The farmer's expenses for pest control would increase due to an increase in bee population.
The financial costs for the farmer would be lowered since more crops would be lost to pests.
The financial costs for the farmer would be lowered since less crops would be lost to pests.
The farmer may be held responsible for increasing chemical pollution.

Sickle cell anemia is known to run in a family. A pedigree chart for this family is shown below.
The parents are shown at the top and from left to right appear as a half-shaded circle next to a half-shaded square. The two are connected by a straight line. Below the parent pair is a vertical straight line connecting to the next row of circles and squares which are the offspring. Starting from left an unshaded square, half-shaded circle, another half-shaded circle, and a completely shaded square are shown. All of these are also connected by a horizontal straight line.
