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.
Aldebaran. n. 1. (Astronomy) a binary star, one component of which is a red giant, the brightest star in the constellation Taurus.ldebaran. n. 1. (Astronomy) a binary star, one component of which is a red giant, the brightest star in the constellation Taurus.
It is a red supergiant and one of the largest stars known after Antares. It is about 550 times larger than the Sun and radiates as more than 100 000 suns combined. Aged only a few million years, Betelgeuse is already approaching the end of his life.More massive a star is more the temperature is high at its center.f Betelgeuse were at the center of our solar system, its radius, â 650 times that of the Sun, would extend between the orbit of Mars and Jupiter. Aldebaran is a red giant of magnitude 0.86 and spectral type K5 III, which means it is orange, tall and it left the main sequence after using all its hydrogen.
