Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: It is selected by a breeder
Concept:

Natural selection is driven entirely by environmental pressures, devoid of conscious intent or planning.

Solution:

  • The statement "It is selected by a breeder" is completely false regarding natural selection.
  • When a human breeder intentionally selects traits, the process is explicitly called Artificial Selection.
  • Natural selection occurs naturally via environmental challenges (predation, climate, food availability).


Why other options are incorrect:

  • Natural selection does act on heritable variations, does improve adaptations, and is strictly regional (a trait advantageous in an arctic environment might be lethal in a desert).

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.
