Question

Malik formed a hypotheses that an increase in atmospheric oxygen levels by 10% would cause red-legged grasshoppers to grow larger than normal. Suppose that malik performs an experiment to test his hypothesis. Which of these actions would represent a scientific mistake in his experiment

Answer 1

C.

He varies the nitrogen and carbon dioxide levels in the air from one trial to the next.

Step-by-step explanation:

Answer 2

Answer : Malik's experiment included to create artificial atmospheric oxygen; in order to perform experiment on red-legged grasshopper for growing it larger than normal, the part of recreating or mimicking the artificial oxygen for the experiment with additional 10% increase seems to be bit difficult and this may create a problem in defining the accuracy and precision for the experiment.
