Question

A scientist hypothesized that oxygen atoms from both carbon dioxide and water are used to make glucose during photosynthesis. However, experimental results using oxygen isotopes showed that all of the oxygen from the water ended up in the oxygen molecules that were produced. None of the oxygen from water was found in glucose. What should the scientist do to best gain scientific understanding of this topic?

Answer 1

There is a need to evaluate about what could have happened, and modify the experimental procedures to retest the hypotheses in a distinct manner.  

Discard the faulty outcomes, which do not encourage the original hypothesis, and repeat the experiment by utilizing the similar approaches.  

Evaluate the procedural mistakes, which occurred in the experiment, and summarize these in a conclusion statement. Ultimately, repeat the experiment and amend the new information to support the original hypothesis.  

Answer 2

(B.) Discard the faulty results that do not support the original hypothesis, and repeat the experiment using the same methods.
