The student provides a focused and detailed description of the main topic, clearly formulating the aim of the investigation and exploring the topic in the introductory paragraphs. Additionally, the background information provided is relevant and sufficiently explores the main topic, including the role of amylase in human metabolism. The biology is explained well enough for the reader to fully understand it without the need for rereading, as the student explores different factors affecting the rate of enzyme-catalyzed reactions. The methodology of the investigation is highly appropriate to the topic, with a focus on answering the research question, and includes appropriate steps to assure the relevancy and validity of the obtained results. The student also shows full awareness of safety hazards, ethical concerns, and environmental issues that can arise during the experiment. The drawbacks of the section include a lack of appropriate details in the research question and an incorrectly stated null hypothesis.
