Explanation: It looks like the student conducted an experiment involving potato cylinders and different concentrations of sucrose solutions. The x-axis of the graph represents the concentration of sucrose solution in mol/dm³, and the y-axis represents the percentage change in the mass of potato cylinders.
Here are some observations based on the graph:
Independent Variable: The independent variable is the concentration of sucrose solution, and it is plotted on the x-axis.
Dependent Variable: The dependent variable is the percentage change in the mass of potato cylinders, and it is plotted on the y-axis.
Trend: The graph shows a trend where the percentage change in mass decreases as the concentration of sucrose solution increases. This suggests an inverse relationship between the concentration of sucrose solution and the mass of potato cylinders.
Critical Points: There might be a point on the graph where the percentage change becomes zero, indicating an isotonic solution where there is no net movement of water into or out of the potato cells.
If you have specific questions or if there's something particular you would like to discuss or analyze from the graph, feel free to provide more details!
