The student's IA demonstrates a focused and detailed description of the main topic, including osmosis, hypertonic and hypotonic solutions, and passive diffusion, all directly connected to the research question on how ethanol concentration affects osmosis in potato cells. Additionally, the background information provided is relevant and well-integrated into the research question, covering topics such as osmosis, passive diffusion, cell membranes, and the effect of solute concentration. The biology is explained clearly and logically, allowing the reader to fully understand without the need for rereading. The student also stated and explained both null and alternative hypotheses, with the alternative hypothesis well-supported by the explanation of how ethanol concentration influences osmosis. Furthermore, the methodology is highly appropriate, focused on answering the research question, and includes appropriate steps to assure the relevancy and validity of the obtained results. However, the student should have shown full awareness of ethical concerns and environmental issues that can arise during the experiment, specifically regarding the use of chemical substances and the environmental risks associated with ethanol.
