Correct Answer: C

Rationale: The correct answer is C, the Lymphatic System. The lymphatic system is responsible for draining clear fluid, known as lymph, throughout the body to protect it from infection. The other choices are incorrect because the pulmonary loop specifically refers to circulation between the heart and lungs, the systemic loop refers to circulation between the heart and the rest of the body, and the immune system is responsible for fighting infections and diseases rather than draining clear fluid.

Correct Answer: B

Rationale: The correct answer is B, Cystic fibrosis. Cystic fibrosis is a genetic disorder that primarily affects the respiratory and digestive systems. It leads to the production of thick mucus in the lungs, causing breathing difficulties and increasing the risk of respiratory infections. Choice A, Asthma, is a chronic respiratory condition characterized by inflammation and narrowing of the airways, but it is not a genetic condition. Choice C, Mycosis, refers to fungal infections and is not a genetic condition specifically affecting the respiratory system. Choice D, Surfactant Deficiency, is a condition related to respiratory distress syndrome in newborns and is not a genetic disorder affecting the respiratory system in general.

Correct Answer: B

Rationale: The correct answer is B. To measure the volume of a cube, you need to use a mathematical formula that takes into account the dimensions of the cube, specifically the length of its sides. Using a measuring wheel alone or a triple beam balance is not suitable for determining the volume of a cube. A graduated cylinder is used to measure the volume of liquids, not geometric solids like cubes.

Correct Answer: C

Rationale: A graduated cylinder is the most suitable tool to measure the volume of both liquids and solids. It works by measuring the displacement of water when the solid is submerged in the graduated cylinder. Choice A, the triple beam balance, is used to measure mass, not volume. Choice B, using a measuring wheel and mathematical formula, is typically used to measure distance or area, not volume. Choice D, a measuring wheel, is used to measure distance, making it inappropriate for measuring the volume of a solid.

Correct Answer: B

Rationale: The correct answer is the Nucleus. The nucleus is responsible for storing genetic material (DNA) and controlling cell functions. Mitochondria are known for energy production, not genetic storage. Ribosomes are involved in protein synthesis, not genetic material storage. The endoplasmic reticulum is involved in protein and lipid synthesis, not genetic material storage. Therefore, the nucleus is the organelle primarily responsible for housing the genetic material within a cell.
