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.

A tall pea plant (Tt) is crossbred with a short pea plant (tt). The Punnett square below shows the separated alleles for two pea plants.

Punnett square showing female parent across the top with a phenotype of tall and a genotype of Tt and a male parent across the side with a phenotype of short and a genotype of tt. Inside the top left box 1 is written, inside the top right box 2 is written, inside the bottom left box 3 is written, inside the bottom right box 4 is written.

Which of the following shows the correct match of the box numbers and the genotype of the offspring?

Group of answer choices

1 = Tt; 2 = Tt; 3 = Tt; 4 = Tt

1 = Tt; 2 = Tt; 3 = tt; 4 = tt

1 = Tt; 2 = tt; 3 = Tt; 4 = tt

1 = Tt; 2 = tt; 3 = tt; 4 = tt

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.
