The correct response is: **The carbon in carbon dioxide is recycled during photosynthesis.**

During photosynthesis, plants take in carbon dioxide from the atmosphere and convert it into glucose and oxygen, effectively recycling carbon in the process.

The correct response is: **The hydrogen in glucose is recycled when water is formed.**

During cellular respiration, glucose is broken down, and the hydrogen atoms from glucose are ultimately used to form water.

The correct response is: **6.**

During photosynthesis, six molecules of water are used in the chemical reaction that produces one molecule of glucose, along with six molecules of carbon dioxide.
Answered by GPT-4o mini
The correct response is: **It was recycled when glucose was formed.**

During photosynthesis, the radioactive hydrogen from the water is incorporated into glucose, effectively recycling the hydrogen atoms in the process.
Answered by GPT-4o mini
The correct response is: **Glucose in the plant’s stem was radioactive.**

This observation provides evidence that the radioactive hydrogen from the water was incorporated into the glucose during photosynthesis, indicating that hydrogen is recycled in this process.
