The sarcomere, which is the basic contractile unit of a muscle, shortens in length when myofilaments contract. The myosin heads pull on the actin filaments, causing them to slide past each other and overlapping more, resulting in muscle contraction.
Liquids and gasses will expand or contract to take the shape of a container.
The myofilaments in a muscle cell are called actin and myosin. Actin and myosin are protein filaments that work together during muscle contraction to generate force and movement.

Yes.
a voltage-sensitive tubule protein changes shape due to an action potential
the myofilaments themselves do not contract, they slide, this is called the Sliding Filament theory, in which the thick filament (Myosin) slides over the thin filament (Actin).
Bundles of myofilaments make up
A myofibril is a bundle of contractile filaments (myofilaments), 1-2 μm in diameter, that are arranged in parallel groups in the cytoplasm of striated muscle cells.
Tropomyosin and troponin are called regulatory proteins because they act like a switch to determine when the fiber can contract and when it cannot.
Muscles in the eye surrounding the lens contract stretching it out, flattening it; or relax, letting it thicken. These changes in shape refocus the lens.

Making changes to a contract. It has nothing to do with the US Constitution.
The specific clause that, when signed by all parties to a sales contract, changes the original terms of the contract is known as an amendment clause.
