Answer:
Occurrence of mud slides after heavy rains.
Explanation:
Soil erosion is defined as the removal of top soil from the land and it affects the fertility of the soil. It is also known as soil degradation.
Soil erosion has both short-term and long-term damage. Short-term damage of erosion includes the occurrence of mudslides after heavy rains which is called landslide. It is a short-term damage because landslides took long-duration to happen and when happened it can be shortly recovered using machines.
Hence, the correct answer is "the Occurrence of mudslides after heavy rains."
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.
