What are two myofilaments that slide past one another to allow muscle cells to contract?
Actin and Myosin
What expand or contract to take the shape of a container?
Liquids and gasses will expand or contract to take the shape of a container.
Does a gas changes to a shape and volume?
SHAPE
What protein changes shape due to an action potential?
a voltage-sensitive tubule protein changes shape due to an action potential
When muscles contract do the myofilaments themselves actually shrink?
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).

What is a myofibril?
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.
What is considered to be a regulatory protein of the myofilaments?
Tropomyosin and troponin are called regulatory proteins because they act like a switch to determine when the fiber can contract and when it cannot.
How does the eye lens focus?
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.
