Answer:
b. muscle fascicle
c. muscle fiber
d. myofibril and. sarcomere
Explanation:
When muscle contracts, the myosin and actin filaments slide antiparallel to one another hence shortening the distance between the adjacent Z-lines of a sarcomere (a functional unit of striated muscle). Technically, nonetheless, the filaments do not shorten. A chain of sarcomeres make up a myofibril. Myofibrils bound together in bundles around a sarcolemma make up a muscle fiber. Several muscle fibers bundled together in an endomysium make up a fascicle. Several fascicles bound together in a perimysium make up a muscle. A muscle has blood vessels and innervated nerves that serve the cells and are bound overall by an epimysium.
The blood vessels and nerves in the muscle do not contract.

<h2>Answer with Explanation </h2>
I have been as of late pondering, on the off chance that I take a sufficiently incredible vitality source (photon) and I have an ideal mirror precisely before it and expect a "producer" shot the light towards the mirror. As impeccable mirrors assimilate no vitality of ANY sort from photons, should this imply the ideal mirrors could never move because of exchange of force of the light? it depends on the mass of the mirror, obviously. Your ideal mirror would have a vast mass, in which case it could assimilate the force change, without engrossing any vitality. A reflection of limited mass will ingest some vitality in a crash that will change the vitality and along these lines the wavelength of the photon. There is no logical inconsistency here.
