Explanation:
Correct Answer: 1-f, 2-e, 3-b, 4-a, 5-c, 6-d
- 1-f: Troponin C → Calcium — Troponin C is the calcium-binding subunit of the troponin complex in muscle fibers. During muscle contraction, Ca²⁺ binds to Troponin C, causing a conformational change that allows actin-myosin interaction.
- 2-e: Thrombocytes → Blood coagulation — Thrombocytes (platelets) are essential for hemostasis. They form the primary platelet plug and release clotting factors that activate the coagulation cascade.
- 3-b: B-lymphocytes → Humoral immunity — B-lymphocytes differentiate into plasma cells that produce antibodies (immunoglobulins), mediating humoral (antibody-mediated) immunity.
- 4-a: T-lymphocytes → Cellular immunity — T-lymphocytes (cytotoxic T-cells, helper T-cells) mediate cell-mediated immunity by directly attacking infected or cancerous cells.
- 5-c: N₂ in blood → Decompression sickness — When animals/divers are under high pressure, nitrogen dissolves in blood. Rapid decompression causes N₂ to come out of solution as bubbles in blood/tissues, causing 'the bends' (decompression sickness).
- 6-d: Macrophage → Phagocytosis — Macrophages are highly phagocytic cells derived from monocytes. They engulf and destroy pathogens, cellular debris, and foreign particles. Example: Kupffer cells (macrophages in liver) clear bacteria from portal blood.
