Physiology - Answers -The function of organisms and their parts (WHY / HOW)
ecophysiology - Answers -a complex interaction between a self-sustaining
physiochemical system and the environment
endo - Answers -internal/within
ecto - Answers -external/outside
homeo - Answers -constant

how much of earth's livable space does the ocean make up? - Answers -99.9%
How much of the Earth's surface is covered by water? - Answers -70%
what is the proportion of salt in ocean water? - Answers -35 o/oo
conformer - Answers -an organism whose internal environment changes as the
external environment changes (cold-blooded)
regulator - Answers -an organism who maintains a constant internal environment as the
external environment changes
osmolarity (mOsm/L) - Answers -total moles of all solutes per liter of solution
--> the ocean has an osmotic concentration of 1000-1150 mOsm/L
what factors affect the concentration of ions in the ocean? - Answers -- runoff
- dissolution (chem rxns)
, - pollution
- upwelling
- precipitation
- calcification
- biological processes
what are the organic molecules? - Answers -proteins, amino acids, glucose, lipids,
nitrogenous waste
diffusion - Answers -the movement of ions from a high concentration to low
concentration
osmosis - Answers -movement of water from a more dilute solution to a more
concentrated one
difference between diffusion and osmosis - Answers -diffusion - movement of particles
within solutions
osmosis- movement of water
Extracelluar Fluid (ECF) - Answers -fluid outside (in between) cells
intracellular fluid (ICF) - Answers -fluid within cells
what are ions important for? - Answers -osmotic balance, signaling buoyancy,
metabolite exchange, metabolic efficiency
how does temperature vary in the oceans - Answers -spatially, temporally, and with
depth
homeotherm - Answers -an animal with a constant body temperature
poikilotherm - Answers -an animal whose body temperature varies with the temperature
of its surroundings
eurythermal - Answers -having a wide temperature range
stenothermal - Answers -having a narrow temperature range
what influences temperature (of organism)? - Answers -- locomotion
- growth
- O2 delivery
- enzymatic machinery
- membrane fluidity and order
- ciliary function
- symbiotic breakdown
