1. What effect does doubling the net force applied to an object have on its acceleration, assuming mass remains constant?

• A. Acceleration doubles
• B. Acceleration is halved
• C. Acceleration remains the same
• D. Acceleration quadruples

Correct answer: a

Rationale: According to Newton's second law (F = ma), if mass remains constant and force doubles, acceleration also doubles.

2. Which hormone, produced by the pineal gland, plays a role in regulating sleep-wake cycles and is often associated with the body's internal circadian rhythm?

• A. Melatonin
• B. Serotonin
• C. Dopamine
• D. Endorphin

Correct answer: a

Rationale: The correct answer is A: Melatonin. Melatonin is a hormone produced by the pineal gland that plays a crucial role in regulating sleep-wake cycles and is closely tied to the body's circadian rhythm. It is often referred to as the 'sleep hormone' because it helps signal to the body when it is time to sleep and wake up. Serotonin (option B) is a neurotransmitter that plays a role in mood regulation and happiness. Dopamine (option C) is involved in reward-motivated behavior and movement. Endorphins (option D) are neuropeptides that act as natural painkillers and contribute to feelings of pleasure. Therefore, Melatonin is the hormone associated with the body's internal circadian rhythm and sleep-wake cycles.

3. Which of the following is a strong base commonly used in cleaning products?

• A. Sodium hydroxide (NaOH)
• B. Ammonium hydroxide (NHâ‚„OH)
• C. Calcium hydroxide (Ca(OH)â‚‚)
• D. Potassium hydroxide (KOH)

Correct answer: A

Rationale: Sodium hydroxide is a strong base commonly used in cleaning products. The other choices are also bases but are not as strong as sodium hydroxide.

4. Which organelle is responsible for controlling the activities of the cell?

• A. Golgi apparatus
• B. Mitochondria
• C. Nucleus
• D. Ribosomes

Correct answer: C

Rationale: Rationale: The nucleus is the organelle responsible for controlling the activities of the cell. It contains the cell's genetic material (DNA) and serves as the command center of the cell, regulating gene expression and directing cellular activities. The nucleus plays a crucial role in cell growth, metabolism, and reproduction. The Golgi apparatus is involved in processing and packaging proteins, the mitochondria are responsible for producing energy in the form of ATP, and ribosomes are involved in protein synthesis. However, none of these organelles have the primary function of controlling the activities of the cell like the nucleus does.

5. What is the term for the reaction between an acid and a base to produce water and a salt?

• A. Combustion
• B. Neutralization
• C. Oxidation
• D. Decomposition

Correct answer: b

Rationale: Neutralization is the reaction between an acid and a base to produce water and a salt. The other choices do not accurately describe neutralization.

6. The statement, “The Good Shepherd Medical Center aims to provide patient-centered care in

• A. Vision
• B. Goal
• C. Philosophy
• D. Mission

Correct answer: A

Rationale: The correct answer is A: "Vision." A vision statement describes the desired future state or long-term goal of an organization. It outlines the aspirations and purpose of the organization, such as providing patient-centered care in this case. Vision statements are forward-looking and inspirational, guiding the organization towards achieving its ultimate objectives. In contrast, a goal is a specific, measurable, and achievable target within a set timeframe. A philosophy is a set of beliefs or guiding principles, while a mission statement defines the organization's core purpose and focus. Therefore, the statement about providing patient-centered care aligns with the concept of a vision statement.
