Preventing top soil erosion is critical in agriculture; this is normally done using various measures such as Planting grass and shrubs, mulching, avoid soil compaction among other methods.
Answer:
relaxation occurs
Explanation:
Muscle contraction, in addition to being responsible for locomotion and various other types of body movements, also promotes the movement of internal organs, such as heartbeat, artery pulsation, transit of the bolus through the digestive tract, among others.
Such processes are made possible by the shortening capacity of myofibrils, which are cytoplasmic filaments of muscle cells. Such myofibrils are made up of several types of proteins, with actin and myosin being the most abundant.
Myosin makes up the thick filaments and is classified as a mechanochemical enzyme or motor protein, because it is able to convert chemical energy into mechanical energy, useful for the mechanism of muscle contraction. When the myosin cycling process generates less stress than the load, muscle relaxation occurs.
