Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Sarcomere is the part between two Z lines.It is the fundamental structural and functional unit of the muscle contraction.The repeating units of sarcomere make up the myofibrils.It has a thin filament (actin), thick filament (myosin).There are zones: a band is the region that has both thick and thin filament.I band only has thin filament and is lighter in appearance.H zone is the region with only thick filament and M line is in the centre of the sarcomere.

Concepts Used:
Locomotion and Movement
Locomotion
The movement of a creature from one place to another is known as locomotion. During the process, there is the action of appendages such as wings, limbs, and flagella. In some animals, like fish, whales, and sharks, locomotion upshots from a wave-like series of muscle contractions. Locomotion helps an organism in finding their food, avoid harsh weather conditions, escape from their predators, etc.
Some examples of locomotion are walking, running, swimming, etc. Movement, on the other hand, refers to any type of motion that need not be localized.

Movement
Movement is generally described as a state of changing the position from rest to motion or vice-versa. Movement can be both voluntary movement and involuntary movement. Movement helps an organism perform essential functions, such as pumping blood to the different parts of the body, etc.
