My Mitosis split and stages. Q1: the cromosomes duplicate, then they both seperate and move to the seperate side of walls. The cells elongates, then its plasma membrane grow in. The cell then divides into two sister cells. ThOse cells are able to produce because thier mother is able to give them what they need to survive.

Q2:1- Interphase- In this stage, simply it is the stage were the cromosomes are preparing to split apart. The cell is very active where the the DNA replicates, and the protiens are being made.

2- Prophase- In the first stage of mitosis, the nucleous starts to fadel and proteins and chromotain, condenses into the chromosomes. Each has two chromatids, they have the same gennetic onfo.

3- Metaphase-Tension applied by the spindle fibers aligns all chromosomes in one plane at the center of the cell.

4- Anaphase: Spindle fibers shorten, the kinetochores separate, and the chromatids (daughter chromosomes) are pulled apart and begin moving to the cell poles.

5- Telophase: The daughter chromosomes arrive at the poles and the spindle fibers that have pulled them apart disappear.

6- Cytokinesis: the spindle fibers that are not connected to that cromosomes they make it so only that one is overlapping.
