Question

Select the correct answer. Malik formed a hypothesis 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? A. He experiments on live grasshoppers instead of preserved ones. B. He focuses on red-legged grasshoppers instead of all kinds of grasshoppers. C. He varies the nitrogen and carbon dioxide levels in the air from one trial to the next. D. He conducts the experiment in a controlled lab setting with a lab partner. E. He measures the mass and length of his specimens at the start of each trial.

Answer 1

Answer: see below

Explanation:: 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.
