IB Biology HL D3.3.1 Homeostasis definition
Practise defining homeostasis through controlled internal conditions such as blood pH, water balance, blood glucose and body temperature.
How this is tested
- state that homeostasis keeps internal conditions stable within narrow limits
- apply the definition to blood pH, water balance, glucose or temperature control
- explain how a change from the norm triggers responses that restore the variable
