CAIE IGCSE Biology EXTENDED 14.4.3 Concept of homeostatic control
Practise recognising homeostasis as negative feedback, using set points, temperature data, flowcharts and body responses to change.
How this is tested
- complete statements or flowcharts linking homeostasis, set point and negative feedback
- explain temperature graph results by linking receptors, impulses, effectors and responses
- distinguish correct negative feedback responses from reversed hot or cold conditions
