1. What is the unit of measurement for force in the International System of Units (SI)?

• A. Newton (N)
• B. Kilogram (kg)
• C. Joule (J)
• D. Meter per second squared (m/s²)

Correct answer: a

Rationale: Force is measured in Newtons (N) in the SI system.

2. The pH scale is used to indicate the concentration of:

• A. Oxygen
• B. Hydrogen ions
• C. Salts
• D. Sugar molecules

Correct answer: A

Rationale: The pH scale measures the concentration of hydrogen ions in a solution, indicating acidity or basicity.

3. Dandruff is caused by

• A. Excessive sebum production (This can contribute to oily dandruff)
• B. Bacterial infection (This can cause scalp folliculitis, not dandruff)
• C. Overgrowth of a specific type of fungus on the scalp
• D. Lack of proper skin hydration

Correct answer: C

Rationale: Dandruff is primarily caused by an overgrowth of a specific type of fungus called Malassezia on the scalp. This fungus feeds on the natural oils produced by the hair follicles, leading to an inflammatory response in some individuals, resulting in flaking and itching. Excessive sebum production can contribute to oily dandruff by providing more food for the fungus. Bacterial infections, such as scalp folliculitis, can cause symptoms similar to dandruff but are not the primary cause. Lack of proper skin hydration can contribute to dry scalp conditions but is not the main cause of dandruff.

4. 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.

5. A new material is claimed to be stronger than steel. You design an experiment to test this claim. What is the MOST important control variable?

• A. The size of the material samples.
• B. The temperature at which the test is conducted.
• C. The force applied to the material.
• D. The color of the material.

Correct answer: A

Rationale: The size of the material samples is the most important control variable because it ensures that the comparison between the new material and steel is fair and accurate. By keeping the size consistent, any differences in strength can be attributed to the material composition rather than variations in sample size. Controlling for size helps eliminate confounding variables and increases the reliability of the experiment results. Temperature, force applied, and color are not as critical for directly testing the strength comparison between the new material and steel.

6. Which of the following is the main function of the kidneys?

• A. To filter waste products from the blood
• B. To produce urine
• C. To regulate blood pressure
• D. To produce hormones that help to control blood sugar levels

Correct answer: A

Rationale: Rationale: A) To filter waste products from the blood: The main function of the kidneys is to filter waste products, excess ions, and water from the bloodstream to form urine, which is then excreted from the body. This process helps maintain the body's internal environment by regulating the balance of electrolytes, fluid volume, and pH levels. B) To produce urine: While the kidneys do produce urine as a result of filtering the blood, the primary function is to filter waste products rather than solely producing urine. C) To regulate blood pressure: The kidneys do play a role in regulating blood pressure by controlling the volume of blood and the concentration of electrolytes in the body, but their main function is waste filtration. D) To produce hormones that help to control blood sugar levels: While the kidneys do produce hormones like erythropoietin and renin that play a role in various physiological processes, such as red
