SimWText 2017-2018 File Edit Go Tools Help Section 5: Biological Consequences of Climate Change Climate Change 23/ 24 Q5.14. In order to avoid extinction, species may respond to climate change in which of the following ways? Check all that apply . Moving to a new location Undergoing new genetic mutations Evolving in response to the new conditions Acclimating to the new conditions Q5.15. Ectotherms are great model organisms for studying climate change because their temperature closely tracks that of theitr environment ue False 05.16. How would species distributions shift if the world were cooling instead of warming?

Explanation / Answer

14. Option C is correct.

Species have to evolve new adaptations by accumulating new mutations to avoid extinction. Acclimatization can provide adaptation to a limited extent. If the climate changes are drastic, organisms can no longer acclimatize.

15. True.

Ectotherms can not control their body temperature.

16. Option B is correct.

If the climate cooling is happening instead of warming, species would migrate to the warmer regions such as equator.

17. True

Rapid environmental changes often lead to species extinction instead of evolution.
