1. Which sentence uses the modal verb "should" correctly?

• A. You should have studied harder for the exam.
• B. I should be going now.
• C. She said she should have taken a different route.
• D. They should be arriving any minute now.

Correct answer: B

Rationale: Option B conveys an intention or expectation regarding the present or near future.

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

• A. Transformational leader
• B. Transactional leader
• C. Servant leader
• D. Charismatic leader

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.

3. Which hormone, produced by the pituitary gland, stimulates the growth and development of bones, muscles, and organs?

• A. Growth hormone (GH)
• B. Thyroid-stimulating hormone (TSH)
• C. Prolactin
• D. Follicle-stimulating hormone (FSH)

Correct answer: A

Rationale: The correct answer is A: Growth hormone (GH). Growth hormone is produced by the pituitary gland and plays a crucial role in stimulating the growth and development of bones, muscles, and organs in the body. It promotes cell division, protein synthesis, and overall growth. Thyroid-stimulating hormone (TSH) stimulates the thyroid gland to produce thyroid hormones, prolactin is involved in milk production after childbirth, and follicle-stimulating hormone (FSH) is responsible for the growth and maturation of ovarian follicles in females and sperm production in males, but they do not directly impact the growth and development of bones, muscles, and organs. Therefore, growth hormone is the hormone specifically known for its role in promoting growth and development in these areas.

4. Testosterone is a crucial hormone in the male reproductive system. What is its primary function?

• A. Egg production
• B. Sperm production and development
• C. Regulation of the menstrual cycle
• D. Milk production

Correct answer: B

Rationale: The correct answer is B: Sperm production and development. Testosterone is a hormone primarily produced in the testes and is essential for the development of male reproductive tissues, including the testes and prostate. It plays a key role in the production of sperm cells (spermatogenesis) and the development of secondary sexual characteristics in males, such as facial hair and muscle mass. Testosterone is not involved in egg production (A), regulation of the menstrual cycle (C), or milk production (D) as these are functions associated with female reproductive hormones.

5. The primary function of the atrioventricular (AV) node within the heart is to:

• A. Generate the electrical impulse for contraction (pacemaker function)
• B. Transmit the electrical impulse from atria to ventricles, regulating the timing of contraction.
• C. Increase blood pressure within the ventricles during systole.
• D. Separate oxygenated and deoxygenated blood flow in the heart.

Correct answer: B

Rationale: The correct answer is B: "Transmit the electrical impulse from atria to ventricles, regulating the timing of contraction." The AV node acts as a gateway between the atria and ventricles, ensuring a coordinated and sequential contraction of the heart chambers. It delays the conduction of electrical impulses to allow the atria to fully contract before the ventricles contract, facilitating efficient blood pumping. Options A, C, and D are incorrect because the primary role of the AV node is not to generate electrical impulses, increase blood pressure, or separate blood flow based on oxygenation status. Understanding the AV node's function is crucial in comprehending the heart's electrical conduction system.

6. A common indicator used to distinguish between acidic and basic solutions is:

• A. Methyl orange
• B. Phenolphthalein
• C. Universal indicator
• D. All of the above are common indicators.

Correct answer: B

Rationale: Phenolphthalein turns pink in basic solutions and remains colorless in acidic solutions
