Metabolism and Adverse Conditions
Dormancy, hibernation, aestivation, daily torpor and migration as ways to survive or avoid metabolic adversity.
How to study Higher Biology
Move from accurate biological mechanisms to unfamiliar data, experimental evidence and justified conclusions. Use current official materials for the written, extended-response and controlled-assignment formats that this question bank does not reproduce.
Core concepts
Concept 1
Explain how reduced metabolic rate conserves energy during dormancy.
Exam cue: Explain how reduced metabolic rate conserves energy during dormancy.
Concept 2
Distinguish predictive and consequential dormancy, hibernation, aestivation and daily torpor.
Exam cue: Distinguish predictive and consequential dormancy, hibernation, aestivation and daily torpor.
Concept 3
Evaluate migration as an energy-costly move to a more favourable environment.
Exam cue: Evaluate migration as an energy-costly move to a more favourable environment.
Risk pitfalls and guardrails
Dormancy survives adverse conditions; migration avoids them.
Guardrail: Check vocabulary, sequence, direction, compartment, units and whether the evidence supports causation or only an association.
Aestivation is associated with heat or drought, not winter cold.
Guardrail: Check vocabulary, sequence, direction, compartment, units and whether the evidence supports causation or only an association.
Memory anchors
Adverse-condition choices
Slow metabolism here or spend energy to move.
Aestivation
A dry or hot-period dormancy.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
