Final answer:
The scientist should conduct further experiments to investigate why the oxygen atoms from water are not found in glucose during photosynthesis.
Step-by-step explanation:
During photosynthesis, the oxygen atoms from water are used to produce oxygen molecules, whereas the oxygen atoms from carbon dioxide are not used in the production of glucose. To gain a better scientific understanding of this topic, the scientist should conduct further experiments to investigate why the oxygen atoms from water are not found in glucose.
They could explore other possible pathways or reactions that occur during photosynthesis and analyze the fate of oxygen atoms from both carbon dioxide and water. They could also study the enzymes and metabolic processes involved in glucose synthesis to determine if there are any factors that prevent the incorporation of oxygen atoms from water into glucose.
