Worked Solution & Example Answer:A student investigated the effect of the presence of four different molecules, R, S, T and U, on the rate of cellular respiration in human liver cells - VCE - SSCE Biology - Question 40 - 2020 - Paper 1
Step 1
Which one of the following graphs is the best representation of the results?
Answer
The best representation of the results is shown in option A. It effectively illustrates the concentrations of carbon dioxide produced by the different molecules R, S, T, and U in a clear bar graph format.
- Molecule R produces 400 ppm, S produces 800 ppm, T produces 600 ppm, and U produces 1000 ppm.
- This bar graph allows for easy comparison of the data, clearly demonstrating the varying levels of carbon dioxide production related to each molecule.
Options B, C, and D do not accurately represent the data: B implies a continuous increase which misrepresents the experimental setup, C displays an inappropriate trend line, and D uses a pie chart which is not suitable for this type of quantitative comparison.
