- Q3A scientist testing the affects of a chemical on apple growth sprays an orchard with the chemical. A second orchard does not receive the chemical. In the fall, the number of apples harvested from each forest is counted. Which of the following is the independent variable?the chemicalthe number of applesthe second orchardthe first orchard30s
- Q4The orchard sprayed with the chemical yields an average of 60 apples per tree, the other orchard yields an average of 40 apples per tree. Based on the data, the scientist wouldtest the chemical on other plants.determine that the chemical increases apple yield.report his data.determine that the results were inconclusive.30s
