Worked Solution & Example Answer:In another experiment, test tube three was compared with test tube four - VCE - SSCE Biology - Question 8 - 2009 - Paper 1
Step 1
The graph of results for tube four would resemble C.
Answer
Based on the experiment, test tube four contains less lactase (0.25 mL) compared to tube three (0.5 mL). Therefore, we can expect a slower reaction rate, resulting in a gradual increase in the concentration of glucose over time. The graph that best represents this behavior is option C, which shows a slow but steady increase in glucose levels over the 10-minute monitoring period.
