Correct Answer: C

Rationale: The correct answer is C because sinuses warm, humidify, and filter air before it reaches the lungs, improving respiratory efficiency. Sinuses have mucous membranes that trap particles and pathogens, preventing them from entering the respiratory system. This process helps to protect the lungs and maintain their health. Choices A, B, and D are incorrect because sinuses do not primarily trap pathogens, direct air down the trachea, or sweep away pathogens towards the top of the trachea.

Correct Answer: D

Rationale: The correct answer is D: Gametes. Meiosis is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. Genes (A) are units of heredity, alleles (B) are different forms of a gene, and chromatids (C) are duplicated chromosomes. These choices are not directly produced by meiosis but are related to genetic material and cell division processes. Gametes are the specific reproductive cells formed through meiosis, making them the correct answer.

Correct Answer: D

Rationale: The correct answer is D because bones are resistant to shattering due to the intricate balance of minerals like calcium and phosphorus, along with collagen fibers. Calcium salts alone (choice A) only provide hardness, not flexibility. Collagen fibers (choice B) provide strength but not hardness. Bone marrow and blood vessels (choice C) support bone health but don't contribute directly to resistance to shattering. The combination of minerals and collagen fibers in choice D provides both hardness and flexibility, making bones resistant to shattering.
