Mitosis simply refers to cell division in which one cell divides and produce two new cells that are identical.
Here are the steps:
(1) Prophase
<span>(a) Early prophase when cells starts to break down some structures and build others up. It sets up the stage when the chromosome is dividing.</span><span>(b) Prometaphase, mitotic spindle begins to capture and organize the chromosomes.
</span>
(2) Metaphase
<span>The spindle has captured all the chromosomes. They lined them up at the middle of the cell making it ready for division.
</span>
(3) Anaphase
<span>The sister chromatids separate from each other and are pulled towards opposite ends of the cell.
</span>
(4) Telophase
<span>The cell is nearly finished dividing, and it starts to re-establish normal internal structures as cytokinesis takes place.</span>

Aids are a infectious agent.
It spends by any contact. ex: sex, hands, and any contact.
If someone has these diseases, they need to contact a doctor ASAP, and get treat. (some diseases can be controlled but not heal, meaning can NOT go away)!
Gene flow is also called gene migration. Gene flow is the transfer of genetic material from one population to another. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring.
