QUESTION 2 Given the following information, what would be considered to be the positive control in this experiment? An experiment is being conducted to test a new organic fertilizer with the hypothesis that it will increases the size of fruit. Three groups of 100 plants each are treated with the same procedures with the exception of the fertilizer used. One group received no fertilizer, another group received the new organic fertilizer and the last group received a commercial chemical fertilizer that has been shown to increase the size of fruit by 20%6. O Group being treated with the new organic fertilizer. O Group being treated with no fertilizer. O Group being treated with the known commercial chemical fertilizer. QUESTION 3 When changing the wavelength on the spectrophotometer, a is used to standardize the instrument. blank base dependent variable independent variable positive control
