<span>When a virus enters the cell of a human body it can start hosting inside the cell and reproduce itself. A virus can easily affect the body at the same time the immune system would activate to fight the viruses. Medication is needed to prevent it from spreading and worsen.</span>
Answer:
The correct answer is: A) the Calvin Cycle alone.
Explanation:
These reactions happen in cells capable of photosynthesis.
The only out of these reactions that require CO2 to take place is the Calvin Cycle. The Calvin Cycle is a series of biochemical processes that occur in the chloroplasts during photosynthesis. <u>The Calvin Cycle uses carbon dioxide (CO2) and water to produce glucose</u>, which will give energy to the cells.
The light reactions occur during photosynthesis in the presence of light and involving photophosphorylation. The light reaction does not make use of CO2, as it takes solar energy and converts it into NADPH and ATP.
This means that Staphylococcus aureus is more tolerant to salt (NaCl), however, E. coli is sensitive to NaCl concentrations more than 10%. This also means that Staphylococcus has more fluid in its cytoplasm, as compared to E. coli, which enables it to tolerate in high salt concentration. Further, this also indicates the ability of both microbes to grow on different media compositions and have different nutritional requirements.
