Earth revolves around the sun, keeping doldrums stationary causes the doldrums to be calm winds. Thus, the correct option is C.
<h3>
Why are the doldrums so calm?</h3>
The Intertropical Convergence Zone, also known as the doldrums or calms by sailors due to its constant lack of wind, is the area where the northeast and southeast trade winds meet. It encircles the Earth near the thermal equator, however its exact location changes with the seasons.
The sunlight beams down directly on the area around the equator, the Doldrums are caused by solar radiation from the sun. Instead of blowing horizontally, this heating causes the air to warm and climb straight up. As a result, there is little or no wind for weeks at a time.

Answer:
The correct answer will be option-C
Explanation:
The CsCl gradient centrifugation in Meselson Stahl experiments is done to separate the bands of the DNA containing isotopes on the basis of difference in the density.
In the experiment, bacterial cultures were grown in the medium of 15N and 14N but if we repeat the experiment with P32 and P31 instead of 15N and 14N and centrifugation is performed then the banding pattern will be the same as of the previous experiment as the method of the replication is same that is semi-conservative.
Thus, Option-C is the correct answer.
During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product. Humans impact the carbon cycle during the combustion of any type of fossil fuel, which may include oil, coal, or natural gas
