Assign each example to the universal muscle characteristic being described.

There are five characteristics of Muscles; namely Responsiveness, Conductivity, Contractibility, Extensibility and elasticity. 
Assigning each example to the universal muscle characteristic being described;
Conductivity; (electrically stimulating a muscle) Local electrical change triggers a wave of excitation that travels along the muscle fiber.
Contractibility; Shortens when stimulated
Elasticity; Returns to its original resting length after being stretched,
Extensibility; capable of being stretched between contractions.
Responsiveness; to chemical signals, stretch, and electrical changes across the plasma membrane.
