- Consider that you are a civilian resident living on the Chatham Island in New Zealand where a long-finned pilot whale stranding event with 100 beached whales is happening and maybe have even been participating in the response to the strandings. Raise specific questions that you may have for the local government or researchers about the stranding. Argue for an alternate hypothesis as to why the event occurred.

Provide examples and interpret data.arrow_forwardPlace the following elements in the strategy to control mosquito populations in the correct order from earliest to latest by numbering them from 1 to 5. a. Scientists genetically modify male mosquitoes in the lab. b. Mosquito offspring produced by the matings do not survive to adulthood. c. GM male mosquitoes mate with normal wild females. d. The mosquito population decreases dramatically. e. Scientists release GM male mosquitoes into the wild.arrow_forwardDirections: Write ADAPT if the statement is under the principle of Jean Baptiste de Lamarck and EVOLVE if the statement is under the principle of Charles Darwin. 1. Species may experience extinction if they are not fitted to live in their environment. 2. Species, which become extinct, just experienced evolution to fit in their environment. 3. Once a trait is developed due to adaptation in environment, it may be passed to succeeding oripnisms. 4. Habitual actions with a specific body part may lead to its changes. 5. Body parts that are of no use but still present in an organism's body are evidence for its ancestor species. 6. Animals with the same body part may have modifications depending on its physical requir. ements. 7. Changes happen in an organism for a long and uniform process. 8. A body part that is no longer used by an organism may lag from its development. 9. Birds grew web-like structure on their feet to be able to feed on the surface of water. 10. Ancestral…arrow_forward
