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? A.) Analyze what could have happened, and change the experimental methods to retest the hypotheses in a different way.
B.)Discard the faulty results that do not support the original hypothesis, and repeat the experiment using the same methods.
C.)Analyze the procedural errors that took place in the experiment, and summarize these in a conclusion statement.
D.)Repeat the experiment and adjust new data to support the original hypothesis.

Answer 1

Answer:

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

Explanation:

During photosynthesis, light energy from sun splits the water and transfers the oxygen from water to the carbon dioxide to produce carbohydrates i.e sugar – glucose. In this process, water gets oxidized and carbon dioxide is reduced.  

Hence, the hypothesis results are not up to the mark which means that there has been issue with the procedure followed to conduct the experiment. Thus, the scientists must try to find out the mistakes done in the procedural stages and hence correct them and re do the experiment.

Hence, option B is correct
