The structural level in which the muscle produces the contraction is known as the muscle fiber.
<h3>What is a muscle fiber?</h3>
A muscle fiber is a single muscular cell that is able to contract by using specialized proteins such as filaments of myosin and actin.
This unit (muscle fiber) is able to contract both in vivo and in vitro by establishing suitable environmental conditions (e.g., proper calcium levels).
In conclusion, the structural level in which the muscle contracts is the muscle fiber.

The correct answer is (b) Jupiter has mass less than that of sun which cannot generate enough pressure which can start hydrogen fusion. Jupiter has similar composition as both are entirely made up of hydrogen and helium. They both differ in the core and mass. The mass of Jupiter is so small as compared that it would not be able to generate enough pressure to start hydrogen fusion. Jupiter's core is made of metallic hydrogen and the core of sun is so hot that the hydrogen splits into electrons and protons. This generates hydrogen fusion.
Thus, Sun a star and Jupiter is not a star.
