Relier Pairs Adaption Version en ligne for the second test par Lee Daniels 1 Four parts of Natural Selection 2 Genetic Bottleneck 3 Adaptations to get food 4 Predator and Prey Adaptations 5 Insecticide resistance Insects develop resistance to the insecticide. Crops are not protected and get ruined by insects. Kills crops. European corn borer Cactus- very deep roots in the desert Chameleon - long, very fast tongue Birds have different shaped and size of beaks to get food in their biome (habitat).
