<span>All cells have the same DNA. They are different because different genes have been locked up and only some of them are expressed. The process began in the embryonic stage, when stem cells are turned into different types of cells by turning off some of the genes.

Sea levels would rise.
Increase in temperature (for example due to global warming) increases the rate of melting of polar ice.
Consequently, the sea levels of the polar ecosystem would increase.
In addition, the melting of the ice caps also increases the temperature of the water in the oceans. As a result, the water expands which also increases the sea levels.
