(2) There is an enormous amount of evidence to support the hypothesis. The hypothesis may then become a theory. Q: What do scientists collect to test a hypothesis? Choices: - arguements - beilefs - books - evidence A:

Question: Answer the following question given this paragraph: Two species may often interact with each other and have a close relationship. Examples include flowers and the animals that pollinate them. When one of the two species evolves new traits, the other species may evolve matching traits. This is called coevolution . You can see an example of this in Figure below . The very long beak of this hummingbird co-evolved with the tubular flowers it pollinates. Only this species of hummingbird can reach nectar deep in the flowers. Q: What is it called when two species evolve matching traits? Choices: - Allopatric speciation - interconnection - spontaneous mutation - coevolution A:
Answer:
coevolution
