1. What is a group of organisms of the same species living in a particular area called?

Correct answer: B

Rationale: A) Community refers to all the populations of different species living and interacting in a particular area. Since the question specifies organisms of the same species, community is not the correct answer. B) Population is a group of organisms of the same species living in a particular area. This term specifically refers to individuals of the same species and their interactions within a defined area. C) Ecosystem includes all the living organisms (biotic factors) and non-living components (abiotic factors) in a particular area and their interactions. While populations are part of an ecosystem, the term 'ecosystem' is broader and includes multiple populations. D) Habitat refers to the specific environment where an organism lives, including the physical and biological factors. It is the place where a population or individual organism resides, but it does not specifically refer to a group of organisms of the same species.

2. Which statement is TRUE about valence electrons?

Correct answer: C

Rationale: Valence electrons are the outermost electrons in an atom's electron cloud and are crucial in forming chemical bonds with other atoms. These electrons determine the reactivity and chemical properties of an element, making option C the correct statement. Option A is incorrect as valence electrons are found in the outer shell, not the innermost shell. Option B is incorrect because valence electrons have lower binding energy compared to inner electrons. Option D is incorrect since valence electrons play a significant role in an element's chemical behavior.

3. The adrenal glands are part of the

Correct answer: B

Rationale: The correct answer is B: endocrine system. The adrenal glands are part of the endocrine system. These small, triangular-shaped glands are located on top of each kidney and are responsible for producing hormones such as adrenaline, cortisol, and aldosterone. These hormones play a vital role in regulating various body functions, including metabolism, immune response, and stress response. Choices A, C, and D are incorrect because the adrenal glands are not part of the immune system, lymphatic system, or respiratory system. While the immune system is involved in protecting the body from infections and diseases, the lymphatic system helps in maintaining fluid balance and immune function, and the respiratory system is responsible for breathing and gas exchange in the body.

4. Which factor affects the gravitational potential energy of an object the most?

Correct answer: B

Rationale: Gravitational potential energy is directly proportional to the height or distance from the ground. As the object is raised higher, its gravitational potential energy increases. While the mass of the object influences gravitational potential energy, the distance from the ground has a more significant impact on it. The gravitational force does not directly affect the gravitational potential energy; it is the force that causes the potential energy to change with height. The shape of the object also does not determine gravitational potential energy, as it is primarily determined by the object's position in a gravitational field.

5. Where does bile, a substance that aids in digesting fats, originate from?

Correct answer: C

Rationale: Bile is produced by the liver to aid in the digestion and absorption of fats. The liver produces bile, which is then stored and concentrated in the gallbladder before being released into the small intestine to facilitate fat digestion. The stomach (option A) is responsible for the initial digestion of food through gastric juices but does not produce bile. The pancreas (option B) secretes digestive enzymes like lipase to further break down fats in the small intestine but does not produce bile. The gallbladder (option D) stores and concentrates bile but does not produce it.
