Answer:
<h2><u>
Upwelling.</u></h2>
Explanation:
When winds blow at the coastline, they push the surface water offshore, so water from the below rises to the surface to fill this void. This upward movement of the water is called upwelling.
The water that is drawn from the below is usually colder, dense and rich in nutrients. It serves as a source of energy and food for the sea population like fish and other sea critters.

Answer:
Cell division is the process in which one cell, called the parent cell, divides to form two new cells, referred to as daughter cells. How this happens depends on whether the cell is prokaryotic or eukaryotic. Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler.
