Correct Answer: C

Rationale: Rationale: 1. According to Charles's Law, when pressure on a gas in a closed system at constant volume is increased, the temperature will also increase. 2. This is because the gas molecules will collide more frequently and with greater force, leading to an increase in kinetic energy and thus temperature. Summary: A: Incorrect - Temperature will not stay the same due to the direct relationship between pressure and temperature. B: Incorrect - Temperature will not decrease when pressure is increased in a closed system at constant volume. D: Incorrect - The relationship between pressure and temperature is known and can be determined.

Correct Answer: D

Rationale: The correct answer is D: Catabolism. 1. Catabolism specifically refers to the process of breaking down large molecules into smaller molecules to release energy. 2. Metabolism (A) is the overall set of chemical reactions that occur in an organism, including anabolism and catabolism. 3. Bioenergetics (B) is the study of energy transformation in living organisms, not specifically the breakdown of molecules. 4. Anabolism (C) is the opposite process of catabolism, involving the building of large molecules from smaller ones, requiring energy input.

Correct Answer: B

Rationale: The correct answer is B: Secondary structure. Secondary structure is defined by the local folds and coils in the protein's polypeptide backbone, such as alpha helices and beta sheets. This level of structure does not involve interactions between different regions of the protein (tertiary) or multiple protein subunits (quaternary). Primary structure (A) refers to the linear sequence of amino acids. Tertiary structure (C) involves the 3D arrangement of secondary structures and other elements in a single polypeptide chain. Quaternary structure (D) pertains to the arrangement of multiple polypeptide subunits in a protein complex.

Correct Answer: C

Rationale: Nociceptors detect pain. They are specialized nerve endings that respond to potentially harmful stimuli. When activated, nociceptors send signals to the brain, resulting in the sensation of pain. Deep pressure (A) and vibration (B) are detected by other types of receptors, while temperature (D) is detected by thermoreceptors. Therefore, the correct answer is C because nociceptors specifically respond to pain stimuli.
