IB Biology SL A1.1.1 Water as life's medium
Practise explaining why water acts as a medium for life, linking its properties to cooling, metabolic reactions and transport in organisms.
How this is tested
- explain how polarity and hydrogen bonding support water's roles in living organisms
- link water remaining liquid over a wide temperature range to metabolic reactions
- apply water properties to its use as a coolant, transport medium and reaction medium
