The correct Answer is:
To solve the question regarding the primary involvement of striated muscles, we can analyze each option step by step: ### Step 1: Understand the Characteristics of Striated Muscles Striated muscles, also known as skeletal muscles, are characterized by their striped appearance due to alternating light and dark bands. They are primarily under voluntary control and are responsible for various types of movements in the body. **Hint:** Look for the key characteristics of striated muscles to understand their functions. ### Step 2: Analyze Each Option - **Option A: Locomotory actions** - Striated muscles are primarily involved in locomotion, as they facilitate movement by contracting and relaxing. Thus, this option is correct. **Hint:** Think about how muscles contribute to movement and physical activities. - **Option B: Changes in body postures** - Striated muscles also play a role in maintaining body posture. They help in stabilizing and adjusting the position of the body, making this option correct as well. **Hint:** Consider how muscles help maintain balance and posture. - **Option C: Transportation of food through the digestive tract** - The transportation of food is primarily done by smooth muscles through a process called peristalsis. Smooth muscles are non-striated, so this option is incorrect. **Hint:** Identify the type of muscle involved in digestive processes. - **Option D: Transportation of gametes through the genital tract** - Similar to option C, the transportation of gametes is also facilitated by smooth muscles, not striated muscles. Therefore, this option is incorrect. **Hint:** Recall the role of different muscle types in reproductive processes. ### Step 3: Conclusion Based on the analysis, the correct answers are: - **A: Locomotory actions (Correct)** - **B: Changes in body postures (Correct)** - **C: Transportation of food through digestive tract (Incorrect)** - **D: Transportation of gametes through genital tract (Incorrect)** Since the question asks for the primary involvement of striated muscles, the best answer is **A: Locomotory actions**, as it directly relates to their main function. **Final Answer:** (A) Locomotory actions
