Instructions for AP BIOLOGY Investigation 12-Fruit Fly Behavior *We will be using Roly-polies (Armadillidium vulgare) to study animal behavior instead of fruit flies. They are members of a family of woodlice in the order Isopoda that are able to roll into a ball. When writing up this lab‚ substitute A. vulgare or “roly-poly” or “pillbug” for Drosophila melanogaster throughout. **You still have to know the basics of fruit fly behavior‚ so be sure to read the lab carefully and save the lab handout to

AP US History 1) In Documents A‚ B‚ and C some problems in their colonial government was that all colonies wanted to unite and become one government but one colony always tried to control all of it.
