There are sunny, foggy, rainy, cold etc days and hence we can say that weather is example of rapid environmental changes.

Answer:
d. the movement of myosin head while attached to actin myofilament
Explanation:
During muscle contraction, the calcium ions released from the sarcoplasmic reticulum in the sarcoplasm bind to troponin which in turn removes tropomyosin from the myosin-binding sites present on the actin. Hydrolysis of ATP at the myosin heads energize them. These myosin heads with stored energy bind to the myosin-binding sites on the actin filaments. In their bound conditions on the actin filaments, myosin heads are called cross bridges. Only one myosin head of a single myosin molecule forms cross-bridge at a time.
