1. Which hormone, produced by the pancreas, regulates blood sugar levels by promoting the uptake of glucose into cells?

Correct answer: A

Rationale: The correct answer is A: Insulin. Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels by promoting the uptake of glucose into cells. When blood sugar levels are high, insulin is released to help cells take in glucose for energy production or storage. Glucagon (option B) is another hormone produced by the pancreas but functions in the opposite way to insulin, increasing blood sugar levels by promoting the release of stored glucose from the liver. Cortisol (option C) and Thyroxine (option D) are hormones produced by the adrenal glands and thyroid gland, respectively, but they do not primarily regulate blood sugar levels like insulin. Therefore, the correct choice is A: Insulin.

2. What type of force opposes the motion of an object moving through a fluid (liquid or gas)?

Correct answer: c

Rationale: Viscous force is the resistance experienced by an object moving through a fluid due to internal friction.

3. Neon (Ne). Both He and Ne belong to Group 18 (Noble Gases) due to their complete and stable outer electron shells.

Correct answer: C

Rationale: Strong nuclear force. This incredibly powerful force overcomes the repulsive electrostatic force between protons and binds the nucleus together.

4. The kidneys are bean-shaped organs that perform several vital functions. Which of the following is NOT a primary function of the kidneys?

Correct answer: C

Rationale: The correct answer is C. While the kidneys perform multiple vital functions, such as filtering waste products from the blood, regulating blood pressure, and maintaining water balance in the body, they do not produce red blood cells. Red blood cell production occurs in the bone marrow, specifically in the spongy tissue called the red bone marrow. Therefore, the kidneys' primary functions do not include producing red blood cells.

5. He asserts the importance of promoting a positive organizational culture in their unit. Which

Correct answer: A

Rationale: The correct answer is A: 'Proactive and caring with one another.' When promoting a positive organizational culture, it is essential to foster a supportive environment where individuals are proactive in their approach and demonstrate care towards one another. This type of culture encourages collaboration, open communication, and empathy among team members, leading to higher levels of job satisfaction and overall performance. Being competitive and perfectionist (option B) can create a stressful and unhealthy work environment, while being powerful and oppositional (option C) or obedient and uncomplaining (option D) can stifle creativity and innovation. Therefore, the most suitable traits for promoting a positive organizational culture are being proactive and caring with one another.

6. Why are isotopes of the same element chemically similar?

Correct answer: A

Rationale: They have the same number of protons. This determines the element's identity and its interactions with other elements, leading to similar chemical behavior, even if the number of neutrons differs.
