Answer:
Combined decrease in sarcomere length.
Explanation:
Sarcomere is the functional unit of the striated muscle tissue. The units get repeated between the two Z lines. The striation under the microscope is shown by the sarcomere.
Actin and myosin protein plays an important role in the muscle contraction. The individual length of the thick (myosin) and thin (actin) filament do not changes and slide over one other. But the sarcomere overall length decreases that result in muscle contraction.
Thus, the answer is combined decrease in sarcomere length.
KCl is a neutral product because KCl is formed from the acid base reaction of KOH and HCl. KOH is a strong base and HCl is a strong acid and when you put them together, you get a neutral product after a chemical reaction. The acid and the base cancel each other out to cause a neutral product.
