Post by: EVIL DOCTOR on June 04, 2009, 06:12:32 pm: look under the dorsal fin u'll find a back spot and is close to the caudal fin then the ans. should be C
Title: Re: Bio P1 Question
Post by: june on June 04, 2009, 06:19:28 pm: yeah q4 is C.. because first of all there is a black spot across the eye so u go to 2 theres also a black spot on the caudal fin so u then go to 3 and again theres a black spot below the dorsal fin which means it is therefore C
