question 1 - 3
a student wants to conduct a science fair project about why plants grow in response to light. his teacher tells him that he should use repeated trials in an experiment. what is the following best explains why replication is important to include in an experiment?

• to provide a control group
• to predict the results of the experiment
• to allow others to conduct the same experiment with similar results
• to ensure that the experimental results are accurate and to minimize experimental errors

Explanation:

Replication in an experiment helps verify results. It reduces the impact of random errors and anomalies. By repeating the experiment, we can be more confident that the findings are accurate and not due to chance or experimental mistakes.

Answer:

To ensure that the experimental results are accurate and to minimize experimental errors.
