1. Which of the following represents a form of potential energy?

Correct answer: C

Rationale: A raised hammer represents potential energy as it possesses stored energy due to its position above the ground. When the hammer falls, this potential energy is converted into kinetic energy as it moves. In contrast, options A, B, and D involve objects already in motion, representing kinetic energy. Choice A, a moving car, is in motion and has kinetic energy. Choice B, a spinning top, is also in motion and exhibits kinetic energy. Choice D, a rolling ball, is already moving and thus has kinetic energy. Therefore, only choice C, a raised hammer, is the correct representation of potential energy among the given options.

2. Which of the following terms refers to the ability to detect and respond to changes in the internal and external environment?

Correct answer: B

Rationale: Responsiveness is the correct term that refers to the ability to detect and respond to changes in the internal and external environment. In this context, growth is incorrect as it pertains to an increase in size or number, reproduction involves producing offspring, and development refers to the process of growth, maturation, and differentiation of cells and tissues. Therefore, 'Responsiveness' is the most appropriate term for the given description.

3. Which condition involves an overactive immune system attacking healthy tissues, leading to inflammation and damage?

Correct answer: B

Rationale: Autoimmune diseases occur when the immune system mistakenly targets and attacks healthy tissues in the body, leading to inflammation and damage. This is different from immunodeficiency, where the immune system is weakened and unable to effectively protect the body against infections. Allergies involve an exaggerated immune response to harmless substances, while cancer is characterized by uncontrolled cell growth. Therefore, the correct answer is autoimmune disease (Choice B) as it specifically describes the scenario of an overactive immune system attacking healthy tissues, distinguishing it from the other conditions listed.

4. What is the primary function of the strong nuclear force?

Correct answer: B

Rationale: The strong nuclear force primarily functions to bind protons and neutrons within the nucleus. It is responsible for overcoming the electrostatic repulsion between positively charged protons, holding the nucleus together. Choices A, C, and D are incorrect because the strong nuclear force specifically acts on nucleons (protons and neutrons) within the nucleus, not on electrons in atomic orbitals or charges outside the nucleus.

5. What is the main function of the pancreas?

Correct answer: C

Rationale: The main function of the pancreas is to produce digestive enzymes that aid in breaking down carbohydrates, fats, and proteins in food. These enzymes are essential for the digestion and absorption of nutrients in the small intestine. While the pancreas also plays a role in regulating blood sugar levels by producing insulin and glucagon, its primary function is to produce enzymes for food digestion. Options A and B are incorrect as the pancreas is not involved in storing food or absorbing nutrients into the bloodstream.
