The student provides a focused and detailed description of the main topic, including the aim of the investigation to calculate the anaerobic respiration rate of yeast for different concentrations of sucrose. They also include a well-formulated and detailed research question, stating the independent variable (concentration of sucrose) and the dependent variable (volume of CO2 produced). The student explains the biology well enough for the reader to understand, including chemical structures and equations underlying the biological processes. The methodology of the investigation is highly appropriate, focusing on answering the research question and including steps to assure 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.
