A sudden shift in the tectonic plates of the earth
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.
The climate change impacts a coral in many different ways. But the main reason that could happen is if the climate were a coral lives is too cold and it begans to die. Corals have feelings toi, when they get a sense that they are going to die they try to leave but if they can't they will just die.
