Answer:
It contains only about an eighth of our sun's mass. Faint red Proxima Centauri is only 3,100 Kelvin (5,100 degrees F or 2,800 C) in contrast to 5,778 K for our sun. So Proxima is 500 times less bright than our sun.
Explanation:
Meiosis, or reductional division, is a process during which exchange of genetic material between the homolog chromosomes (crossing-over and recombination) takes place and such a division of the genetical material occurs the four daughtercells
have received each only one set of chromosomes (they are haploid, in
contrast to the mother cell which contained homolog chromosomes and was
diploid)
<span>have each a distinct genetical composition, also different from that of the parental cell.
Meiosis is divided into twofases: meiosis I and meiosis II.
