Answer:
Thermohaline circulation is influenced by changes in density gradients. These density gradients are affected by the salinity and temperature of the ocean’s water. Cold water is denser than warm water and salt water is denser than freshwater. As water cools off, it sinks. As water evaporates, the salt concentration of the remaining water increases because the salt from the evaporated water remains. This causes the water to sink and circulate.

<span>Nucleus, the control center of the cell is the organelle which intiates, enables, and manages the various simplex. compound and complex cellular activities. It also stores the DNA of the cell which is then replicated and recopied over a hundredth and thousandth times over through cell division processes. In the nucleoplasm -nucleolus, the inner part of nucleus of a cell is where the DNA to mRNA and to protein; vice-versa happens. <span>
