3. Which vitamin is essential for collagen production, a key component of connective tissues?

Correct answer: B

Rationale: The correct answer is B: Vitamin C. Vitamin C is essential for collagen production, which is a key component of connective tissues. Collagen is a protein that provides structure and strength to various tissues in the body, including skin, bones, and tendons. Vitamin C plays a crucial role in the synthesis of collagen by acting as a cofactor for enzymes involved in collagen formation. Deficiency in Vitamin C can lead to impaired collagen production, resulting in weakened connective tissues and potential health issues like scurvy. While Vitamin A, D, and E are important for various bodily functions, Vitamin C specifically stands out for its vital role in collagen synthesis.

4. How does the potential energy of an object change when it is compressed?

Correct answer: b

Rationale: When an object is compressed, it stores potential energy due to its altered position or configuration.

5. Which of the following factors would NOT affect the solubility of a solid solute in a liquid solvent?

Correct answer: b

Rationale: Pressure does not significantly affect the solubility of solid solutes in liquid solvents. The other choices are factors that can influence solubility.

6. The dome-shaped muscular structure that separates the chest cavity from the abdominal cavity is the:

Correct answer: A

Rationale: The correct answer is A: Diaphragm. The diaphragm is a dome-shaped muscular structure that plays a crucial role in respiration by contracting and flattening during inhalation to increase the volume of the thoracic cavity, allowing the lungs to expand and fill with air. It separates the chest cavity (thoracic cavity) from the abdominal cavity. The sternum (B) is a flat bone in the center of the chest, the pericardium (C) is a double-layered sac that surrounds the heart, and the trachea (D) is the windpipe that connects the larynx to the bronchi. Therefore, the diaphragm is the correct answer in this case.
