How long does it take (from enlistment to fleet) to become a Navy combat medic? I'm working on a screenplay, and in order to keep my backstory details straight I'm interested in knowing specifically whether a character who enlists in the Navy might be deployed as a combat medic in the following calendar year.
Meiosis /maÉªËoÊsÉ¨s/ is a specialized type of cell division which reduces the chromosome number by half. This process occurs in all sexually reproducing single-celled and multi-celled eukaryotes, including animals, plants, and fungi.
Unlike the bodyâs other cells, the cells in the egg and sperm â called gametes or sex cells â possess only one chromosome. Gametes are produced by meiosis cell division, which results in the divided cells having half the number of chromosomes as the parent, or progenitor, cells. In the case of humans, this means that parent cells have two chromosomes and gametes have one. During fertilization, gametes from the sperm combine with gametes from the egg to form a zygote. The zygote contains two sets of 23 chromosomes, for the required 46.
