Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Autolysis
Concept: Programmed destruction of tissue can serve as a survival mechanism at the organismal level.

Solution: When a lizard sheds its tail (autotomy), the physical detachment at the fracture plane involves rapid, programmed cellular destruction. At the cellular level, this massive destruction of tissue is facilitated by autolysis, where lysosomes burst and digest the cells at the detachment site to allow a clean break.

Distractor Autopsy: Autophagy is internal recycling (the cell survives). Phagocytosis and intracellular digestion involve eating external food.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
