1. Which muscle type is characterized by a combination of voluntary and involuntary control, is striated, and is responsible for pumping blood throughout the circulatory system?

• A. Skeletal muscle
• B. Smooth muscle
• C. Cardiac muscle
• D. Connective tissue

Correct answer: c

Rationale: The correct answer is C: Cardiac muscle. Cardiac muscle is characterized by a combination of voluntary and involuntary control, as the heart can beat involuntarily while also responding to signals from the autonomic nervous system. It is striated, meaning it has a striped appearance under a microscope due to the arrangement of contractile proteins. Cardiac muscle is responsible for pumping blood throughout the circulatory system, making it crucial for maintaining circulation and delivering oxygen and nutrients to tissues. Skeletal muscle (option A) is primarily under voluntary control and is responsible for movement, while smooth muscle (option B) is predominantly involuntarily controlled and found in organs like the intestines. Connective tissue (option D) provides support and structure but is not a muscle type responsible for pumping blood.

2. Alexandra is tasked to organize the new wing of the hospital. She was given the authority to

• A. Benevolent –authoritative
• B. Consultative
• C. Exploitive-authoritative
• D. Participative

Correct answer: D

Rationale: The correct answer is D: Participative. In a participative leadership style, Alexandra would involve the team members in decision-making and encourage their input when organizing the new wing of the hospital. This approach fosters collaboration, empowers team members, and can lead to better outcomes as everyone's perspectives are considered. Benevolent-authoritative (A) involves a leader who is kind and caring but makes decisions independently. Consultative (B) involves seeking input from team members but making the final decision independently. Exploitive-authoritative (C) involves a leader who uses their authority in a self-serving or oppressive manner. In this scenario, with the task of organizing a new wing of the hospital, a participative approach would be most effective in engaging the team and utilizing their expertise.

3. Which of the following is a risk factor for developing kidney stones?

• A. Consuming a diet rich in fruits and vegetables
• B. Maintaining adequate hydration with water
• C. Having a family history of kidney stones
• D. Regularly engaging in moderate exercise

Correct answer: C

Rationale: Having a family history of kidney stones is a risk factor for developing them because genetics play a role in kidney stone formation. Individuals with a family history are more likely to inherit genetic factors that increase the likelihood of developing kidney stones. While consuming a diet rich in fruits and vegetables, maintaining adequate hydration with water, and regularly engaging in moderate exercise are generally healthy habits that can help prevent kidney stones, they are not direct risk factors for developing them. Therefore, option C, having a family history of kidney stones, is the correct answer.

4. Which of the following describes a scalar quantity?
