There are 4 stages in Mitosis...
Prophase:
It is the first phase in which the chromatin coil to become chromatids, and those chromatids pair up and the nuclear membrane surrounding them dissolves. The centrioles move to each end (pole) of the cell.
Metaphase:
Where the paired chromatids align in the centre of the cell and spindle fibres attach to them at the centromere.
Anaphase:
The centrioles act as anchors, tearing the paired chromatids away from each other using the spindle fibres. Each paired chromatid moves to either (the opposite) end of the cell.
Telophase:
Where the chromatids elongate to form chromatin, and a nuclear membrane begins to form around the chromatin at each end of the cell. Cytokinesis occurs in this stage as the cell separates into two daughter cells. In animal cells, there is cleavage as the two cells are starting to separate. In plant cells, a plate begins to form.
Answer: The satellite must orbit at a speed of about 7,000 mph
Explanation: the higher the orbit, the longer the satellite can stay in orbit.

By moving substances across membranes, transport proteins make everything from nerve impulses to cellular metabolism possible. Without transport proteins, for example, the sodium-potassium gradient that allows our nerves to fire would not exist.
A. Certain factors are dominant, and others are recessive
