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? he experiments on live grasshoppers instead of preserved ones. he focuses on red-legged grasshoppers instead of all kinds of grasshoppers. he varies the nitrogen and carbon dioxide levels in the air from one trial to the next. he conducts the experiment in a controlled lab setting with a lab partner. he measures the mass and length of his specimens at the start of each trial.
