The table below shows the scientists who were involved in some major scientific discoveries.Field of scienceDiscoveryScientists involvedBiologyCell theoryMatthias Schleiden, Theodor SchwannPhysicsLaw of conservation of energyJames Joule, Julius von Mayer, Hermann von Helmholtz, Baron KelvinBiologyMitosisWalther Flemming, Eduard StrasburgerBased on this information and what you know about the research of these scientists, which statement describes the relationship between multiple approaches and major discoveries?
Answer
A
Major discoveries relating to cells are more likely to occur when multiple approaches are used.
B
Major discoveries are only made when more than one scientist is involved in the research.
C
Major discoveries are more likely to occur in physics than in biology when multiple approaches are used.
D
Major discoveries are sometimes confirmed because multiple approaches yield the same results.
Explanation
The discoveries listed were reached or supported by scientists studying different evidence and using different approaches. For example, Schleiden studied plant cells and Schwann studied animal cells, and their findings supported the same cell theory. This illustrates how multiple approaches can yield consistent results and help confirm a major discovery.
