Answer:
a difference between mitosis and meiosis is that, during mitosis there is only one cell division, so the cell goes through the steps of prophase, metaphase, anaphase, and telophase once.Specialized cells are unable to survive independently of each other and have to develop complex systems of communication such as the circulatory and nervous systems in order to survive. If one system dies, the entire organism is likely to follow.
Explanation:
"Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other. Unlike smooth muscle and cardiac muscle, skeletal muscle is under voluntary control. Similar to cardiac muscle, however, skeletal muscle is striated; its long, thin, multinucleated fibres are crossed with a regular pattern of fine red and white lines, giving the muscle a distinctive appearance. Skeletal muscle fibres are bound together by connective tissue and communicate with nerves and blood vessels."

The mitochondria is where oxygen is needed.
Mirror neurons fire demonstrates the ability of primates to empathize with another organism.
Mirror neurons are a class of neurons that modulate their activity both when an individual executes a specific motor act and when they observe the same or similar act performed by another individual.
Recent studies have shown that the mirror neurons have been hailed as a cornerstone of human empathy, language, and other vital processes.
These neurons are initially found as motor command neurons present in the frontal lobes of the brain and the prefrontal areas of the brain.
These are neurons which fire when a person moves and these are regular motor command neurons, orchestrating a sequence of muscles that allow the person to move something or do some other action.
A subset of these neurons also fire when that person simply watches another person move and do exactly the same action. So these neurons are performing a virtual reality simulation in the brain.
Another example of this is phantom limb.
