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

Answer:

1) Consider what might have happened and modify the experimental method to retest the hypothesis differently.

2) Toss out any incorrect results that do not support the original hypothesis and repeat the experiment using the same methods.

3) Examine the procedural flaws that occurred during the experiment and summarize them in a conclusion statement.

4) Repeat the experiment, but this time adjust the new data to support the original hypothesis.

5) Toss out any incorrect results that do not support the original hypothesis and repeat the experiment using the same methods.
