1. What is the law that states energy can neither be created nor destroyed?

Correct answer: B

Rationale: The correct answer is the Law of Conservation of Energy. This law states that energy cannot be created or destroyed, only transformed from one form to another. The Law of Conservation of Matter (Choice A) is related to mass and the preservation of mass in a closed system, not energy. The Law of Universal Gravitation (Choice C) describes the force of attraction between objects with mass. The Law of Inertia (Choice D) states that an object will remain at rest or in uniform motion unless acted upon by an external force.

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

Correct answer: B

Rationale: Neutralization is the correct term for the reaction between an acid and a base to produce water and a salt. During neutralization, the hydrogen ions from the acid react with the hydroxide ions from the base to form water, and the remaining ions combine to form a salt. Combustion involves a reaction with oxygen, oxidation is the loss of electrons, and decomposition is the breakdown of a compound into simpler substances. These processes do not accurately describe the reaction between an acid and a base to produce water and a salt.

3. Which of the following compounds often contains a carboxyl group?

Correct answer: C

Rationale: The correct answer is C: Amino Acids. Amino acids, the building blocks of proteins, contain both an amine group and a carboxyl group. The carboxyl group (-COOH) is crucial for the structure and function of proteins as it participates in peptide bond formation. Carbohydrates and DNA do not typically contain carboxyl groups as a functional group. Glycolipids consist of a carbohydrate chain linked to a lipid, but they do not inherently contain a carboxyl group.

4. Which part of the brainstem controls heart rate and breathing?

Correct answer: A

Rationale: The medulla oblongata is a critical part of the brainstem responsible for regulating essential functions such as heart rate, breathing, and blood pressure. It houses centers that oversee these involuntary processes, making it the correct answer. The pons, midbrain, and thalamus do not primarily control heart rate and breathing, thus making them incorrect choices for this question.

5. What is the main function of the nervous system?

Correct answer: B

Rationale: The main function of the nervous system is to control body movement and coordination by transmitting signals between different parts of the body. Choice A is incorrect because the immune system, not the nervous system, is primarily responsible for fighting infections. Choice C is incorrect as regulating metabolism is primarily handled by the endocrine system. Choice D is incorrect because the transportation of oxygen is mainly the function of the circulatory system, specifically the blood.
