||Were there obvious behavioral differences between the control groups
and the antifreeze-exposed groups? If yes, describe.
||Did the concentration of antifreeze in the water influence the degree
of behavioral change? If yes, describe.
a safe level of exposure. In other words, was there an antifreeze
concentration that did not appear to cause an effect over
the 4-minute observation period? How could you tell?
acute (rapid, short-term) effect of antifreeze on the worms
indicate anything about what the long-term or chronic (lifetime)
effects might be?
||Is behavior the only possible measure of effect? Why or why not?
||Can you determine from this experiment the cause of death of the
||Is it possible that while antifreeze affects the health of worms,
it has no effect on humans? (Is it also possible that antifreeze has
no effect on worms but adversely affects human health?) If yes, describe.
