Astudent 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? a descriptive investigation cannot show a cause-and-effect relationship between bacteria growth and possible factors affecting growth. a descriptive investigation is always more expensive than an experimental investigation. a descriptive investigation usually does not involve much data collection to support a hypothesis. a descriptive investigation provides little prior knowledge or background information about bacteria growth.
