Answer 2

The answers to the given question are as follows;

1. White muscle fibers are better adopted to perform fast contraction. (Option B)

• White Muscles have less myoglobin and mitochondria, making them seem white. The eyeball Muscle is an example of a White Muscle.
• White Muscle is a kind of muscular tissue seen in fish that is composed of fast-twitch Muscle Fibers that contract swiftly.
• White Muscles are required for fast swimming motions and escape reactions.

2. The functional efficiency of a muscle depends upon its girth.   (Option B)

• Increased axon diameter leads to increased action potential velocity in axons.
• The internal resistance of fiber reduces as its diameter increases. Because internal resistance reduces quicker than membrane resistance, the distance the membrane potential may travel is enhanced by increasing the diameter.

3. Contusion is included in soft tissue injuries. (Option A)

• Contusion is included in soft tissue injuries. Thus, option A is correct.

4. Strain is not a soft tissue injury. (Option A)

• Soft tissue injury refers to damage to our muscles and skin. The bones do not fracture in this accident, and the internal organs are unaffected.
• This injury happens as a result of physical activity such as sports or strenuous exercise.
