Interactions between actin and myosin filaments of the sarcomere are responsible for muscle contractions. The I bands contain only thin (actin) filaments, whereas the A bands contain thick (myosin) filaments.

The size of a generator is based on what the connected load will be. Add up all of the connected wattages that will be connected to the generator at one time and add ten percent, this will be the size of the generator you will need. Some equipment does not show the wattage on its nameplate. To find the wattage use the following formula Watts = Amps x Volts.
Transformers are sized by the secondary connected load. If the wattage of the load is not given, use the following equation to find it. Watts = Amps x Volts.
The smooth endoplasmic reticulum is a vast network of membrane-bound vesicles and tubules. It does the following: 1. lipid and steroid hormone synthesis 2. breakdown of lipid-soluble toxins in liver cells 3. control of calcium release in muscle cell contraction
It is the amperage that will kill you. In fact the amperage range is in the milliamps (one thousandths of an amp) that are dangerous. Less than 1/2 milliamp no sensation 1/2 to 2 milliamps Threshold of perception 2 to 10 milliamps muscular contraction 5 to 25 milliamps painful shock (may not be able to let go) Over 25 milliamps Could be violent muscular contraction 50 to 100 milliamps Ventricular fibrillation over 100 paralysis of breathing.
I'm not sure of the following, but scientists have discovered similar fossils in vastly different places suggesting that these places were once connected.

contraction
Lorentz contraction, or length contraction, coresponds to following formula: l = l0 * sqrt(1-V2/c2)
In short, the basic contraction unit of the muscle is the sarcomere. Many sarcomeres work serially and in parallel to acheive the full contraction ability of the muscle. The sarcomere is made up of many filaments of Actin and Myosin, two types of protein based filaments that reach out towards each other from opposing sides of the sarcomere. When the muscle is at rest, the Actin and myosin filaments overlap each other the least. In order for the muscle to contract, the filaments from the opposing sides slide over each other thus pulling both walls of the sarcomere towards each other, with them. When the muscle is fully contacted, the filaments overlap each other the most. The sliding motion is activated by calcium that floods the sarcomeres (at the end of a process that is triggered by a command from a motor nerve). The calcium reveals sites on the Actin filaments at which molecular 'whips' extending from the Myosin filaments, can throw themselves, attach, pull, and leave, using the muscle's energy reserves in the process. Each molecular whip works at its own time (much like cylinders in an internal combustion engine), so that in any given time, contact between the filaments is being made by some of the whips.
