Answer 1

THE FARMER AND THE FLY

The agricultural research facility has set up a new program for controlling the fly population in the chicken houses. The facility has purchased two additional insecticides, Formula B and C. These insecticides are equally strong as Formula A, but have different chemical formulas. The facility has set up the following program for using the three insecticides.









Use your knowledge of variation, evolution and natural selection to answer the following questions.

1. At the end of year one, to which insecticide will the living flies be resistant? Explain your answer.



2. What will happen in year two after the first spraying of insecticide B?




3. Why is it a good strategy for the facility to use Formula C insecticide during year three instead of using Formula A again?





4. As year four begins the facility has directed the farmers to go back to using Formula A. They find that Formula A is as effective as it was the first year it was used during year one. What happened to the flies that caused this to occur?





5. How would you design an investigation to support or reject your proposed explanation for why Formula A insecticide worked during year four?
