The student clearly states the independent variable as the source of plant proteases and the dependent variable as the rate of gelatin proteolysis. The research question outlines the method of analysis, specifying that the gelatin proteolysis will be measured by mass loss over a 4-hour period. The student provides a detailed background theory relevant to the research question and explains the choice of techniques used for measurement effectively. However, the student does not adequately explain the sampling technique for selecting fruits or the rationale behind the number of trials, which should have been included. The methodology is well-documented, allowing for reproducibility, and includes a thorough discussion of controlled variables, safety, ethical, and environmental considerations.
