o test a new voice feature in a cockpit design, a flight simulator was used. The simulator was programmed to give visual readings of flight information, or to give visual and voice readings of flight information. All test pilots were put through a simulated emergency landing procedure, but were randomly assigned to the visual, or visual and voice conditions. Flight experts rated each pilot’s performance in the simulator on a scale of 1 (very poor) to 10 (excellent). In the space provided, answer the four questions. 1) What is the Independent variable? 2) What is the dependent variable? 3)What is the Control group? 4)What is the experimental group?

Agenetically 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? a- the financial costs for the farmer would be lowered since less crops would be lost to pests. b-the financial costs for the farmer would be lowered since more crops would be lost to pests. c-the farmer may be held responsible for increasing chemical pollution. d-the farmer's expenses for pest control would increase due to an increase in bee population.
