Steps Involved in scientific method are ?
Correct answer: D. Accumulated data -> Hypothesis -> Observation & experimentation -> New data -> Conclusion
- A. Hypothesis ->Accumulated data -> observation & experimentation -> conclusion
- B. New data -> Conclusion -> Accumulated data -> Observation & experimentation
- C. Accumulated data - New data - Observation & experimentation - Hypothesis -> Conclusion
- D. Accumulated data -> Hypothesis -> Observation & experimentation -> New data -> Conclusion
Explanation
A scientific investigation generally begins with accumulated observations or data, followed by a hypothesis. The hypothesis is tested through observation and experimentation, which produce new data before a conclusion is drawn. Option a is tempting because it includes the same steps, but it places the hypothesis after experimentation.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
