Correct Answer: D

Rationale: The correct answer is D: Influenza. Influenza is caused by a virus, specifically the influenza virus. Step-by-step rationale: 1. Influenza is a contagious respiratory illness caused by the influenza virus. 2. Viruses are known to be the causative agents of influenza. 3. Asthma (A), Cystic Fibrosis (B), and Epiglottitis (C) are not caused by viruses; asthma is a chronic inflammatory disease, cystic fibrosis is a genetic disorder, and epiglottitis is usually caused by bacteria.

Correct Answer: A

Rationale: Gas exchange takes place in the alveoli, which are tiny air sacs at the end of the bronchioles. Alveoli have a large surface area and thin walls, allowing for efficient exchange of oxygen and carbon dioxide. Bronchioles, bronchi, and trachea are part of the airway passages and are not directly involved in gas exchange. Alveoli are specifically designed for gas exchange due to their structure and proximity to the capillaries.

Correct Answer: A

Rationale: The correct arrangement of the small intestine segments is Duodenum, Jejunum, Ileum. The duodenum is the first segment where digestion occurs. The jejunum is the middle segment responsible for absorption, followed by the ileum for further absorption and passage of undigested material to the large intestine. Option A is correct as it follows the natural anatomical order and functional progression of the small intestine segments. Options B and C are incorrect as they incorrectly order the segments. Option D is also incorrect as there is a correct arrangement.

Correct Answer: B

Rationale: The correct answer is B: Remodeling. Bone remodeling is the process of breaking down and rebuilding bone tissue to maintain bone strength and repair micro-damage. It involves osteoclasts breaking down old bone and osteoblasts forming new bone. Ossification (A) is the process of bone formation. Calcification (C) is the deposition of calcium salts in tissues. Osteoporosis (D) is a condition characterized by weakened bones due to loss of bone density, not the process of breaking down and rebuilding bone tissue.
