The Hellenic calendars, the Hebrew Lunisolar calendar and the Islamic Lunar calendar started the month with the first appearance of the thin crescent of the new moon. However, the motion of the Moon in its orbit is very complicated and its period is not constant.
Each daughter cell will also have 18 chromosomes. This is because daughter cells are identical to the original cell. Although during the process of mitosis the number of chromosomes changes, the final number of chromosomes in each daughter cell is always the same number as were in the original cell. This question is archived.
Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell.part from this reduction in chromosome number, meiosis differs from mitosis in yet another way. Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes.
