The following statements about freshwater systems are true except:
Oligotrophic lakes have low biological production and low oxygen.
Lake turnover is temperature & wind driven is critical to the productivity of large
temperate lakes.
Approx 60% of all above-ground freshwater resides in 3 lake systems.

All of the following statements are true except:
Marine bony fishes are hypo-osmotic to their environment so they need to drink a lot
to work against water naturally diffusing out of their bodies.
Sharks and rays are slightly hyper-osmotic to seawater so water diffuses though their
gills and they need a salt gland to pump out the salts.
Freshwater fishes are hyper-osmotic to their environment so don't need to drink much
but need specialized cells to pump in Cl- and Na+ ions.

All of these are true.
In the population size estimation lab, imagine we violated the assumption that each
group was equally efficient at collecting snails. In fact, if all the groups in the
Wednesday and Thursday labs were more efficient at collecting snails compared to
the groups in the Monday and Tuesday labs, how would that skew the Depletion
estimate?
