First of all, 800 of plasticize frogs of red and brown colors were made in similar size to use in experiment. From June 14 to July 20 on 2006, those model frogs were placed on 40 transects, where many kinds of habitats reside including brown leaf-litter and white backgrounds. Both brown and white backgrounds are equally visible to predators and multiple marks on a single model are only counted as a single attack. After 48 hours, frog models were collected. 4. What are the major results? A. Brown-colored samples were likely to be attacked about twice higher than the rate f red-colored samples. 2% of the attack marks were committed by birds leaving U or V-shaped marks. 5. What conclusion did they make about their hypothesis/goal? A. Both striking- colored appearance and chemical defense in denotation frog are been accepted as an example of apostasies. Therefore, conspicuous colored frog is less likely to be attacked by its predators. 6. What new hypothesis/goal emerges from the results? A. The new goal is to find more components of the characteristics of U or V shapes from bird’s attacks as some information of those are lacking. 7.
