Answer – The Tide
The regular rising and falling of ocean water due to the gravitational pull of the Sun and Moon is known as the ocean tide. Primarily, it is the moon that is chiefly responsible for the rising and falling of ocean water; the gravity of the sun only reinforces the moon's gravity.
Some scientists hypothesize that the eukaryotic cells are really the result of symbiotic processes!
Specifically, the internal organs of the cells could be a remnant of a symbiotic relationship in which one cell lived inside of another cell. These two cells then both split upon reproduction and eventually the cell inside was reduced to an organelle.
But according to this theory, it is very likely that the prokaryotic cells engaged in a number of symbiotic relationship, and that this actually lead to the emergence of eukaryotic cells!

Prophase- *Nuclear membrane
disappears
( so chromosomes can
move around)
Metaphase- Chromosomes
line up in the middle of the cell
Anaphase-*Chromosome copies
pull apart from each other.
Telophase-<span>*Nuclear division
has finished and nuclear membrane reappears</span>
<span> This is the process for Meiosis 1 not for 2 (FYI)</span>
