Sorry forgot to post the choices. =P

Answer 3

Woah @thewinterfawn how did you know the option before it was posted :O you're magic!

I think option D is also very relevant (and it might be the best option) and gives you a direct relation between chemical concentration and death rate. HOWEVER, you are unable to determine what is actual effect of the drug (i.e. physiological changes to the fish) without doing experimental work in the lab. The question asks to determine 'survival of a fish species', which you cannot get from experimental results from a lab only naturalistic observations, which is close to option D

Answer 4

I had this problem when I took biology 2 years ago... maybe my memory is magic. xD

Answer 5

@thewinterfawn LOL impressive! Was that the right answer though? Im still leaning towards D, but A is my second guess.

Answer 6

WAIT! its definitely A... no one would ever increase a potentially deadly chemical in nature... All bets are off. winner: @thewinterfawn

Answer 7

haha. I love biology... I think I got a 97 in that class. (:

Answer 8

Thank you, I answered it using my brain right before I saw your reply. =P

Answer 9
