Explanation:
According to this question, a student performs an experiment where she places apple fruit on one location and places apple and banana together in another location. She follows the steps of the scientific method in performing this experiment.
The steps involved in the scientific method include:
- Making an observation
- Constructing an hypothesis
- Testing the hypothesis (experimentation)
- Analyse the result
- Draw a conclusion
The student in this question has already made the observation that when bananas are kept near other fruits, the other fruits ripen faster. She has hypothesized that bananas must have an influence on the ripening process. She tests the hypothesis via an experiment described above. Hence, the next step is to ANALYZE THE RESULTS she will get after 5 days and DRAW A CONCLUSION based on that.
