Excitability is the special functional feature of muscle tissue that .
a) gives muscle tissue the ability to stretch by the contraction of an opposing muscle
b) allows electrical impulses to travel along the cells' sarcolemma, leading to contraction
c) gives muscle tissue the property of passive recoil after being stretched
d) gives muscles their ability to shorten and generate pulling force
e) All of the listed responses are correct.

Option-B

Explanation:

The excitability is the property of cell which allows the cellular response to the stimulus which comes as an electrical impulse.

When the muscle cell or tissue is said excitable it means that the muscle tissue or cell response to the electrical impulses.

In the given question, the electrical impulse travels down the motor neurons and reaches the muscle. In the muscle, T-tubules transfer the impulse to the sarcolemma where the calcium is stored. As soon as the impulse reaches the sarcolemma, the calcium is released which can bind to the troponin molecule make the myosin binding site available and the cross-bridge is formed as a result of which the muscle can contract.

Thus, Option-B is correct.

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
