Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: 70% to 90%
Concept:

Water is the fundamental matrix of life, making up the vast bulk of cellular and extracellular fluid.

Solution:

  • In almost all living organisms, water is the most abundant compound.


  • Across different species and tissue types, the generalized overall water content typically ranges from 70% to 90% of the total body mass.


  • For instance, humans are roughly 70% water, while some organisms like jellyfish reach up to 99%.


Why other options are incorrect:

  • Values like 10-60% drastically underestimate the required aqueous environment needed for biochemical reactions to sustain life.

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.
