Mitosis can occur in a diploid nucleus, that is, one containing pairs of chromosomes representing each of its parents or in a haploid one containing a single set of chromosomes. Meiosis, often called reduction division, yields four daughter nuclei with the number of chromosomes reduced to half the original number. The overall result is that one diploid nucleus becomes four haploid nuclei.

The life of Aldebaran. Before Aldebaran was anything it started off as a large/ relatively cool mass of gas, part of a nebula. As gravity causes the gas to contract, its temperature rises, eventually becoming high enough to trigger a nuclear reaction in its atoms.he life of Aldebaran.
