(04.03 HC) A doctoral student is studying the genetic makeup of a species of jellyfish that occurs at low, middle, and high latitude regions of the Pacific Ocean. On an oceanographic expedition, she collects specimens of the jellyfish throughout its range. Upon returning to the laboratory at the university, an assistant places all of the jellyfish in an aquarium with an average temperature of approximately 20°C. After a few days, he notes that almost two-thirds of the jellyfish have died. Using the figure below, how would you explain which jellyfish likely make up the bulk of the survivors and what the mistake was? (3 points) © 2016 CC-BY-SA
