Answer:
Sarcomere
Explanation:
The muscle fiber / myofibrils consist of 2 types of filaments - actin and myosin. The myosin filaments are thick filament whereas the actin filaments are the thin filament.
In addition to this, the muscles have A-band and I-bands. These bands give the muscles alternate light and dark colour band structure. In the A-band, myosin filaments are present, whereas in the I - band the actin filaments are found.
In I-band 2 Z-lines are located. The area between the Z-lines is called sarcomere. In this sarcomere region both actin and myosin filaments present.
When muscles get contracted the length of the sarcomere shorten. The actin and myosin filaments overlap in this area. A cross-bridge form between them, with the help of filamentous protein titin.
The oxygen in the water molecule attracts the most electrons and in so doing attracts a slightly negative charge.
The answer is Climate change. It will take decades for the
coral reef to recover from the catastrophic climatic changes including El Nino

the corals. It has negative effects on coral populations in some ways. This
includes the Color Bleaching, Coral Disease, and Ocean Acidification.
