  1. Telling you the answer isn't really helping you.


  2. 1 is excretory; insects

    2 is arachnids

    and 3 is tracheae; book lungs

    what a dingbat you must be!.......3 was an obvious give away since gills are indicative of underwater inhabitants such as fish and neither insects nor spiders fall into that description!...that one was process of elimination alone since 3 of the answers had the word gills in them that should have pretty much left only 1 possibility wouldnt ya think!?!
