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?
A. The survivors were likely collected from the dark gray areas on the map. those from other regions could not adapt

B. The survivors were likely collected from the light gray areas on the map those from other regions could not adapt.

C. The survivors were likely from the black areas of the map but had the most advantageous genes of those collected.

D. The survivors were likely from the black areas of the map but adapted to the difference in temperature in the laboratory.
