This condensation is needed to allow the chromosomes to move along the mitotic spindle without becoming tangled or broken during their distribution to daughter cells. DNA in this highly condensed state can no longer be transcribed, so all RNA synthesis stops during mitosis.
A planet in our solar system is like the earth it is stable to live on but anything can happen while you are on it but and a dwarf planet it is not for everyday life so humans can not live on a dwarf planet like they could on one in the solar system

Division of labor is essentially when tasks are divided and carried out by specific parts. This occurs in cells, where different tasks are distributed among different parts, referred to as the organelles. For example, the mitochondria in the cell produce energy to carry out cellular activities. The nucleus is involved in cellular division and other genetic functions. In such a manner, the "labor" that a cell has to perform is divided among its organelles.
The Sun is the energy source for almost all life on earth.
