When the liquid metal that creates the outer core of the earth passes through a magnetic field, it begins to carry the electric current through the liquid. This current makes its own, much stronger magnetic field.
This is because not all genes are expressed at the same time, so not all the proteins are present at a certain moment. The mechanisms that cell uses to control gene expression are called regulation of the gene expression. Thanks to regulation of the genes, cells have the ability to increase or decrease the production of specific gene products such as proteins. This property is important for the adaptability of an organism because it allows the cell to express protein when needed.
