The answer is sliding filament.

Muscle fibers are made up of myosin and actin filaments that straddle one another in alternating sequence. The myosin has myosin heads that act on the actin and enable the myofibrils to slide across each other in opposite directions. This causes the muscle to shorten hence contract. This is an energy-requiring process (hence hydrolyses ATP) and also requires calcium ions. In an animation, the myosin would seem to ‘walk’ on the actin filament.

How many electrons are transferred in the iconic bond between sodium and chorine in NaCI
Yanka [14]

Explanation:

Sodium Na, has atomic number of 11, and a configuration of 2, 8, 1

Chlorine Cl, has atomic number of 17, and a configuration of 2, 8, 7

Thus, to form an ionic bond Sodium transfer its one outermost electron to chlorine.

Hence Sodium becomes Na+ (2 ,8) while Chlorine becomes Cl- ( 2, 8, 8) in NaCl and both have stable octet structure.
