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?
In the question below is given a statement followed by two courses of action numbered I and II. You have to assume everything in the statement to be true and on the basis of the information given in the statement, decide which of the suggested course of action logically follow(s) for pursuing. Statement: Poor soil management practices and the use of heavy machinery have destroyed the soil structure making it unsuitable for plant growth. Courses of Action: I: The farmers should plant cover crops to improve the degraded soil. II: The farmers should increase the use of artificial machinery for reducing the effort in ploughing.
In making decisions about important questions, it is desirable to be able to distinguish between ‘strong’ arguments and ‘weak’ arguments. ‘Strong’ arguments are those, which are both important and directly related to the question. ‘Weak’ arguments are those, which are of minor importance and also may not be directly related to the question or may be related to a trivial aspect of the question. The questions below if followed by two arguments numbered I and II. You have to decide which of the arguments a ‘strong’ argument is and which a ‘weak’ argument is. Statement: Prohibiting the usage of artificial food colours in food items is correct? Arguments: I. Yes, as the chemicals used in these artificial colours would cause many health issues to humans if consumed. II. No, because by using those it makes food look more attractive and appealing.

Essentially in an experiment involving bacteria, we measure Optical density of the media where the bacteria grow at different time point from the same flask. If we have 2 or more types of bacteria and want to investigate whether the growth curve of those bacteria are significantly different, what do you think the best analysis can be applied for this purpose?
