Match the termsZ-disc, sarcomere, A band, H zone, I band, and M line with the most closely related descriptions given below: The dark band containing the entire length of the thick filament The band of proteins in the middle of the H zone The boundary between sarcomeres The functional unit of contraction The middle region of the A band containing only thick filaments The light band containing only thin filaments Introduction: Musclesare formed of muscle fibers. Muscle fibers are formed of proteins and usually, the fibers are striated. The basic unit of striated muscles issarcomere. The muscle fibers are formed of myofibrils. These myofibrils are formed of alternate sections of the sarcomere. Two important proteins of the filament are myosin and actin. Sarcomeresappear as light and dark bands. The different regions of the bands have different names such as I band, A band, H zone, Z-disc, and M line.

(This is a 2-part work, Part 1 is done, only Part 2 is to be worked on at the bottom)Part 1 (Done): Describe the levels of structural hierarchy for the human body, starting with the organismal level and ending with the chemical level. In addition, you should make sure you link each level to the previous level, emphasizing the structural relationships. The human body is organized into a structural hierarchy that progresses from the macroscopic organismal level down to the microscopic chemical level. Each level builds upon the previous one, creating increasingly complex structures. Below is the hierarchy, from largest to smallest, with explanations linking each level to its predecessor: 1. Organismal Level The entire living human body.Relationship: All lower levels work together to sustain life at this highest level. 2. Organ System Level Groups of organs working together to perform major functions.Examples: circulatory, nervous, digestive systems.Relationship: The organismal…
