<h3>Answer;</h3>
2, 1, 2, 1
<h3><u>Explanation</u>;</h3>
Silver chloride reacts with Copper (II) fluoride to form Silver fluoride and Copper (II) chloride.
AgCl (aq) + CuF2 (aq) ----> AgF (s) + CuCl2 (aq)
The balanced chemical equation will be;
2AgCl (aq) + CuF2 (aq) ----> 2AgF (s) + CuCl2 (aq)
Balancing a chemical equation ensures that the Law of conservation of mass is conserved , such that the number of atoms of each element on either side of the equation is equal.
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.
