Mitosis is the process in which a eukaryotic cell separates the chromosomes in its cell nucleus, into two identical sets in two daughter nuclei.[1] It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two daughter cells containing roughly equal shares of these cellular components. Mitosis and cytokinesis together define the mitotic (M) phase of the cell cycle - the division of the mother cell into two daughter cells, genetically identical to each other and to their parent cell.

Why is it important to reduce the chromosome number by half during mytosis?
mytosis creates sex cells - either eggs (in girls) or sperm (in boys). They have 1/2 the number of chromosomes. When an egg and sperm combine, they create one full cell - one half plus one half = one whole. The fetus is created from that one full cell.
What happen during metaphase stage of mitosis?
In metaphase, the chromosomes line up in the center of the cell (aka the metaphase plate or equatorial plate) and then the spindle fibers attach to the centromeres. Centromeres: the center of the two conjoined chromosome pairs where they will break into two halves in the next phase Picture of metaphase on Wikipedia: http://upload.wikimedia.org/wikipedia/commons/thumb/0/07/Metaphase.svg/800px-Metaphase.svg.png
When was sex invented?
when evolution found that mytosis was no longer the most efficiant way to reproduce
What do you call a composition of a amoeba?
An asexual single cell organism who reproduces by mytosis, or splitting the parent cell in half.
During what phase does cytokenisis begin?
Cytokenisis is the last step in Mytosis. It makes the two identical cells pinch into two.

What is the shortest period in the cell cycle?
Mitosis, also called the 'M' phase. actually that answer is incorrect it is actually cytokinesis actually cytokinesis is part of the M phase
How does the cytoplasm divide in plant and animal cells?
meiosis Meiosis is wrong, plant cells cytoplasm don't divide they form cell plates in between one cell creating a new cell.
As a male how can i increase my chances of producing more x female sperm?
You cant. Each sperm cell is part of a set of four. One pair always contain the x chromasomes and ther other pair contain y chromasomes. This is because each set of four are produced from one germ cell. The germ cell first undergoes Myosis in which the homologous pairs a separated not the chromatids. This produces tow cells with each with one different set of the genome, one will have the X chromatid and the other have the Y. These two cells then both undergo mytosis as in a normal cells where in each one the chromatids split giving two identicle cells. This means that you children always have a 50% chance of being male or female.
What is Lady Gaga's catchphrase?
She first says," this is the manefesto of mother monster. On GOAT, government owned territory in space, a birth of magnificent and magical porportions took place. But the birth was not finiate it was infiniate. As the wombs numbered and the mytosis of the future began it was percieved that this infamous moment in life is not temperal it is eternal. And thus began the beginning of the new race a racewithin the race of humanity a race which bears no prejudice no judgment but boundless freedom. But on that same day as the eternal mother hovered in the multiverse another more terrifying birth took place the birth of evil. And as she herself split into two rotating in agony between two ultimate forces the pendulum of choice began it's dance. It seems easy you imagine togevitie instantly and unwaveringly towards good. But she wondered how can I protect something so perfect without evil.
