The muscle cells divide through Mitosis, a cellular division comprised of several other substeps.
The final step of the cell division is the cytokinesis by which two new cells are formed from cell with a multiple number of nucleus after the replication process. This steps follow the telophase.
It involve both experimentation and repeated observations
The machine is plugged into an electrical source, which gets the motor's wheel spinning. The machine is then unplugged and the wheel keeps spinning under its own inertia. Then electrical energy is extracted from the spinning wheel
