The Earth can be divided into one of two ways – mechanically or chemically. Mechanically – or rheologically, meaning the study of liquid states – it can be divided into the lithosphere, asthenosphere, mesospheric mantle, outer core, and the inner core. But chemically, which is the more popular of the two, it can be divided into the crust, the mantle (which can be subdivided into the upper and lower mantle), and the core – which can also be subdivided into the outer core, and inner core

Explanation:
Histones are proteins that bind to the DNA in order to form highly compacted structures named nucleosomes, the basic structural units of DNA packaging in eukaryotic genomes. A nucleosome is a segment of DNA wound around an octamer (8) of histones, i.e., two copies each of the histones H2A, H2B, H3, and H4. These histones are positively charged in order to interact with the negatively charged DNA molecule. During transcription, reducing histone positive charge decreases the interaction between DNA and histones in the nucleosomes, thereby opening the chromatin to favor the access of the transcriptional complex and thus facilitates gene expression.
