1) The results you predict as a result of a controlled experiment can be described as an hypothesis, such as “selection of Wisconsin Fast Plants with the most trichomes in the first (parent) generation will result in an increase in trichome number in the plants of the second generation.” You are making a prediction based on scientific knowledge of selection, and are able to quantify the number of trichomes. This is your experimental hypothesis. A null hypothesis for your experiment...
