Expert Solution & Answer

Explanation of Solution

There are two stages in the photosynthesis, light reaction, and dark reaction. The main work of these stages is to generate energy for making food to the plants. During the light reaction, one electron from a water molecule is stripped out. The atoms of oxygen from the two water molecules join together and form diatomic oxygen. This diatomic oxygen is released and center of chlorophyll binds new water molecules to produce more diatomic oxygen. For this particular production of the single oxygen molecule, four electrons are used.

Conclusion

During the process of photosynthesis the free oxygen atom joins with the other free oxygen atom to produce oxygen gas.

We will be starting a group project next week where you and your group will research and ultimately present on a current research article related to the biology of a pathogen that infects humans. The article could be about the pathogen itself, the disease process related to the pathogen, the immune response to the pathogen, vaccines or treatments that affect the pathogen, or other biology-related study about the pathogen. I recommend that you choose a pathogen that is currently interesting to researchers, so that you will be able to find plenty of articles about it. Avoid choosing a historical disease that no longer circulates. List 3 possible pathogens or diseases that you might want to do for your group project.
