For example, modern medical imaging technology allowed biologists to discover structures called the "interstitium" that are now being evaluated as a new organ because of their importance in the physiology of the human body. Although they have different approaches for investigating scientific phenomena, the three types of scientific inquiry work together to help scientists understand phenomena. When something new is discovered, the first types of scientific inquiry will be [ Select ] ["hypothesis-driven experiments", "develop models/theory", "observational descriptive studies"] . Once these initial studies lay a foundation of knowledge about the new discovery, [ Select ] ["hypothesis-driven experiments", "observational descriptive studies", "develop models/theory"] can begin to test various aspects related to it.
