Their method of obtaining energy

Question 10

Which of the following is the correct order of steps in the scientific method?

Accepted Answer

Observation → Hypothesis → Experiment → Data Analysis → Conclusion → Peer Review & Publish

Question 11

A scientist observes that even after sterilizing a broth, cells reappear in the broth over time. The scientist then asks: 'Why do cells reappear in the broth after sterilization?' and designs/conducts an experiment. Which of the following is a hypothesis?
