Question

Graph the rate of cellular respiration in germinating (Table 7-3) vs. non-germinating (Table 7-2) lentils by plotting levels of CO₂ detected in the BioChamber 250 over ten minutes, collected at 1-minute intervals.  Plot CO₂ results of the germinating lentils and the non-germinating lentils on the same graph and use a key to distinguish between the two lines. The independent variable, time elapsed in minutes, should be plotted on the x-axis, and the dependent variable, CO₂ levels in ppt, should be plotted on the y-axis. If needed, add break lines between 0 and the first evenly spaced interval on the y-axis in order to stretch out data. Include calculated slopes (CO₂ Rate of Respiration) from Table 7-4 next to each line on your graph. Upload a digital version of this

Answer 1

The graph is plotted between the time elapsed on the X-axis and the cellular respiration of the germinating and non-germinating lentils on the Y-axis.
