General Flashcards
1
Q
Benefits to aquatic life
A
Water is wet: gas exchange, fertilization, waste.
Universal solvent: nutrient uptake. Water density: no need for skeleton. Thermal stability: easier to function.
2
Q
Challenges to aquatic life
A
Water absorbs light: photosynthetic creatures need shallow water.
Low oxygen carrying capacity you. Diffusion rate slower.
Density and viscosity: slower movement.
Solvent and pollutioneasier to dissolve. CO2 is easily absorbed.
Freshwater can be temporary and struggle with osmolarity.

Q
‘reynolds’ #
A
= inertial force/viscous force
If high, viscosity doesn’t have much impact
