Water property that (3 different):
1) makes us so cold so fast when swimming
2) moderates coastal temperatures
3) makes us work hard to move in water than air
1) water is good thermal conductor
2) water has a high specific heat capacity
3) water's higher viscosity

Name which biomolecule (3 different):
1) forms cell membrane
2) forms membrane channels
3) quick energy & exoskeletons
1) membrane = lipids
2) membrane channels = proteins
3) quick energy/exoskeletons = carbohydrates

3 Differences gyres & the great ocean conveyor:
location
what drives them
what they move
Gyre is surface current; GOC is deeper
Gyre driven by wind; GOC by density
Gyre moves thermal energy (heat); GOC diss. oxgen
