1. Which respiratory structure is responsible for the humidification and warming of inhaled air?

Correct answer: c

Rationale: The correct answer is C: Nasal passages. The nasal passages are lined with mucous membranes that produce mucus to humidify and warm the inhaled air before it reaches the lungs. This process helps to protect the delicate lung tissues from drying out and becoming irritated. The trachea, larynx, and bronchi play important roles in the respiratory system, but specifically, the nasal passages are primarily responsible for humidifying and warming the air as it enters the body.

2. Nuclear binding energy represents the energy required to:

Correct answer: B

Rationale: Nuclear binding energy is the energy required to hold the protons and neutrons within a nucleus together. This energy is necessary to overcome the electrostatic repulsion between positively charged protons in the nucleus. Option A, separating an electron from its atom, is related to ionization energy, not nuclear binding energy. Option C, causing nuclear fission, involves splitting a heavy nucleus into smaller nuclei, releasing energy but not directly related to the binding energy. Option D, inducing nuclear fusion, involves combining two light nuclei to form a heavier nucleus, also not directly related to the energy required to hold protons and neutrons together within a nucleus.

3. The external body covering, providing protection and contributing to temperature regulation, is composed of:

Correct answer: B

Rationale: The correct answer is B: Epithelial tissue (skin). The skin is the external body covering that provides protection against physical, chemical, and biological factors. It also plays a crucial role in regulating body temperature by controlling heat exchange with the environment through processes like sweating and blood vessel constriction or dilation. Muscle tissue (option A) is responsible for movement, bone marrow (option C) produces blood cells, and cartilage (option D) is a type of connective tissue found in joints. Therefore, epithelial tissue (skin) is the most suitable option as it directly addresses the functions of the external body covering.

4. Acids are generally characterized by a sour taste and the ability to:

Correct answer: B

Rationale: Acids release hydrogen ions (H+) in solution, allowing electrical conductivity

5. Her former manager demonstrated passion for serving her staff rather than being served. She

Correct answer: C

Rationale: The correct answer is C: 'Servant leader.' A servant leader prioritizes the needs of their team members, focusing on serving them rather than expecting to be served. This is evident in the scenario where the former manager showed passion for serving her staff. Servant leaders are known for their humility, empathy, and commitment to the growth and well-being of their team. This leadership approach fosters a positive work environment, builds trust, and promotes collaboration among team members.

6. Which of the following minerals is important for bone health and is stored in bones by the skeletal system?

Correct answer: C

Rationale: The correct answer is C: Calcium. Calcium is essential for maintaining strong and healthy bones. It is a key mineral stored in bones by the skeletal system, where it provides structural support and strength. Adequate calcium intake is crucial for preventing bone diseases like osteoporosis and ensuring proper bone formation and density. Iron (A), Sodium (B), and Magnesium (D) are important minerals for various bodily functions but are not primarily responsible for bone health and storage in bones by the skeletal system.
