Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Homeostasis
Concept: Definition of homeostasis.

Solution: Homeostasis is the physiological maintenance of a stable internal environment (including pH, temperature, water, and glucose balance).

Why other options are incorrect:
  • Option A & Option C: Adaptation and evolution refer to long-term genetic changes in populations over generations.

  • Option B: Thermoregulation is a specific sub-category of homeostasis restricted to temperature regulation.

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.
