1. Which of the following is NOT a function of the integumentary system?

A. Regulation of body temperature
B. Protection from pathogens
C. Synthesis of vitamin D
D. Production of digestive enzymes

Correct answer: D

Rationale: The correct answer is D: "Production of digestive enzymes." The integumentary system primarily consists of the skin, hair, nails, and glands. Its main functions include regulating body temperature through processes like sweating and shivering, protecting the body from pathogens and external threats, and synthesizing vitamin D when exposed to sunlight. However, the production of digestive enzymes is not a function of the integumentary system. Digestive enzymes are primarily produced by organs such as the pancreas and salivary glands to aid in the breakdown of food in the digestive system, which is separate from the functions of the integumentary system.

2. What is the meaning of the idiom "to bite off more than one can chew"?

A. To be overly confident
B. To take on more than one can handle
C. To be easily discouraged
D. To be meticulous in planning

Correct answer: B

Rationale: The idiom warns against undertaking a task exceeding one's capabilities.

3. The body's first line of defense against pathogens includes:

A. Phagocytes
B. Antibodies
C. Memory B cells
D. T lymphocytes

Correct answer: A

Rationale: Rationale: Phagocytes are a type of white blood cell that plays a crucial role in the body's innate immune response, which is the first line of defense against pathogens. Phagocytes engulf and digest foreign particles, such as bacteria and viruses, helping to prevent infection and disease. Antibodies (option B) are produced by B cells and are part of the adaptive immune response, not the first line of defense. Memory B cells (option C) are also part of the adaptive immune response and are involved in mounting a faster and stronger response upon re-exposure to a pathogen. T lymphocytes (option D) are another type of white blood cell involved in the adaptive immune response, specifically in cell-mediated immunity.

4. Which type of muscle is characterized by voluntary control and is responsible for body movement?

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

Correct answer: c

Rationale: The correct answer is C: Skeletal muscle. Skeletal muscles are characterized by voluntary control, meaning they are under conscious control, allowing us to move our body parts as desired. These muscles are attached to bones and are responsible for movements such as walking, running, and lifting objects. Cardiac muscle (A) is found in the heart and is involuntary, while smooth muscle (B) is found in internal organs and is also involuntary. Connective tissue (D) provides support and structure to the body but is not responsible for body movements.

5. A birthday party hat has a cone-shaped top with a radius of 5cm and a height of 12cm. What is its volume?

A. 60 cu cm
B. 120 cu cm
C. 150 cu cm
D. 180 cu cm

Correct answer: C

Rationale: Use the formula for volume of a cone: (1/3) * Ï€ * (radius)^2 * height. Substitute the values: (1/3) * Ï€ * (5cm)^2 * 12cm â‰ˆ 150 cu cm.

6. She surfs the internet for more information about leadership styles. She reads about shared

A. Leadership behavior is generally determined by the relationship between the leaderâ€™s
B. Leaders believe that people are basically good and need not be closely controlled
C. Leaders rely heavily on visioning and inspire members to achieve results
D. Leadership is shared at the point of care.

Correct answer: B

Rationale: The correct answer is B because the statement 'Leaders believe that people are basically good and need not be closely controlled' aligns with the concept of shared leadership. Shared leadership involves distributing leadership responsibilities and authority among team members based on the belief that everyone has valuable contributions to make. This approach fosters a sense of trust and empowerment within the team, allowing individuals to take initiative and collaborate effectively. In contrast, option A refers to leadership behavior being determined by the relationship between the leader and followers, which is not directly related to the concept of shared leadership. Option C emphasizes visioning and inspiration, which are important aspects of leadership but do not specifically address the shared nature of leadership. Option D mentions leadership being shared at the point of care, which is too specific and does not encompass the broader concept of shared leadership.
