The student effectively incorporates relevant and appropriate source material in their essay, particularly from accredited scientific sources. The use of secondary sources, such as aseptic techniques and nonpathogenic E-coli, was suitable for addressing the research question. However, the student could improve by providing clearer explanations for technical terms and ensuring consistent and appropriate use of symbols, equations, and SI units throughout the essay. Additionally, the methodology section lacked specific information, impacting the effective incorporation of source material. Overall, the essay maintains an academic and analytical tone without being oversaturated with subject-specific terms, contributing to its readability.
