Question

A student wanted to know the most effective way to grow bacteria in a lab. He conducted a descriptive investigation instead of an experimental investigation. What is a limitation of his investigation? O A descriptive investigation cannot show a cause-and-effect relationship between bacteria growth and possible factors affecting growth. O A descriptive investigation is always more expensive than an experimental investigation. aner O A descriptive investigation usually does not involve much data collection to support a hypothesis. O A descriptive investigation provides little prior knowledge or background information about bacteria growth.​

Answer 1

Answer:

C). A descriptive investigation usually does not involve much data collection to support a hypothesis.

Explanation:

The limitation of a descriptive investigation is that 'it lacks sufficient data to support the proposition.' A descriptive investigation does not test the validity of a truth or distinct methods of growing it or to make comparisons between them. It rather focuses only on describing in-depth instead of practically examining the validity of the fact and using it to supporting the claim made in the hypothesis, unlike an experimental investigation. Thus, option C is the correct answer.
