Question

the graph shows the rate of alcoholic fermentation for an anaerobic bacterium at different temperatures.
rate of fermentation
(graph with temperature (°c) on x - axis (0, 10, 20, 30, 40) and rate of fermentation (sec) on y - axis (0, 25, 50, 75, 100), curve peaks around 20 - 30°c)
based on the graph, the optimum temperature for this anaerobic bacterium to perform fermentation is between 20°c and 30°c. what would be an appropriate follow - up experiment?
○ set up an experiment at these temperatures: 10, 12, 14, 16, 18, and 20°c
○ set up an experiment at these temperatures: 20, 22, 24, 26, 28, and 30°c
○ set up an experiment at these temperatures: 30, 32, 34, 36, 38, and 40°c
○ set up an experiment at these temperatures: 40, 42, 44, 46, 48, and 50°c

Explanation:

The optimum temperature range is between 20°C and 30°C. To find the exact optimum temperature, we need to test temperatures within this range with smaller intervals. The second option (20, 22, 24, 26, 28, 30°C) is within 20 - 30°C, allowing a more precise determination of the optimum temperature. The first option is below 20°C, the third is above 30°C, and the fourth is far above, so they don't help refine the optimum in the 20 - 30°C range.

Answer:

B. Set up an experiment at these temperatures: 20, 22, 24, 26, 28, and 30°C
