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.
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.
