The x-axis shows the temperature and the y-axis shows the killing time. This is with respect to spores in a suspension. Curve a = 100,000 spores/ml and b= 1,000 spores/ml. Above curve a is the region of spores killed and below the region b is the region of spores survived. Which of the following do we comprehend from the above?

Correct Answer: Greater the spore concentration, more heat resistant the suspension
1. The area formed by the triangles is more when the spore concentration is more and since this region denotes the number of spores surviving, the first explanation makes sense. 2. Since the starting point of ‘a’ on the y-axis is higher than in the other suspension, the first statement makes sense. All the other statements definitely aren’t comprehended by the graph and some of them are only speculations by various researchers.
