Creating experiment or observations that allow data relevant to the hypothesis to be collected. Drawing conclusions that support or refute (reject) the hypothesis. Adaptation: is the evolutionary process (takes time) whereby a population becomes better suited to its habitat. Inherited characteristics of living organism that enhances their chance of survival and reproduction in specific environment. Prefer cold waters but can survive in warm tropical water. Feed on almost every marine mammal species available throughout the range. Killer whales is in resident population in alaska & bc feed exclusively on fish and squid. Transient(coming from other areas) killer whale in alaska & bc only feed on mammals. As a group, they create area where they can trap the smaller fishes together and then they take turn eating.
