2. What property of a wave determines the loudness of sound when heard by the human ear?

Correct answer: b

Rationale: The amplitude of a sound wave correlates with its perceived loudness by the human ear.

3. Which type of waves are capable of interference and diffraction?

Correct answer: d

Rationale: Both longitudinal and transverse waves can exhibit interference and diffraction phenomena.

4. Which force opposes the relative motion between surfaces in contact?

Correct answer: b

Rationale: Friction is the force that opposes motion between surfaces in contact.

5. Recognize the opposing muscle pair.

Correct answer: A

Rationale: The bicep and tricep muscles are antagonistic muscle pairs, meaning they work in opposition to each other. The bicep is located on the front of the upper arm and is responsible for flexing the elbow joint. The tricep is located on the back of the upper arm and is responsible for extending the elbow joint.

6. Which protein complex in the sarcomere is responsible for the thick filament?

Correct answer: B

Rationale: The correct answer is B: Myosin. In the sarcomere, the thick filament is composed of myosin protein. Myosin is responsible for the interaction with actin filaments during muscle contraction, forming cross-bridges that generate the force required for muscle movement. Actin (choice A) is a component of the thin filament in the sarcomere, while tropomyosin (choice C) and troponin (choice D) are regulatory proteins associated with muscle contraction but are not part of the thick filament. Understanding the specific components of the sarcomere is crucial for comprehending muscle contraction mechanisms.
