Verified step by step guidance

Step 1: Begin by identifying the primary function of muscle tissue. Muscle tissue is specialized for movement, which is achieved through contraction.

Step 2: Understand the mechanism of contraction. Muscle cells contain proteins like actin and myosin that interact to produce contraction, enabling movement.

Step 3: Compare the options provided. While muscle tissue can transmit electrical impulses (important for initiating contraction), store calcium (necessary for contraction), and interact with hormones, these are secondary functions. The ability to contract and produce movement is its most distinguishing characteristic.

Step 4: Eliminate options that describe secondary functions or characteristics shared with other tissues. For example, transmitting electrical impulses is also a characteristic of nervous tissue, and storing calcium is a function of bone tissue.

Step 5: Conclude that the most distinguishing characteristic of muscle tissue is its ability to contract and produce movement, as this is unique to muscle tissue and central to its function.
