Scenario Kenneth and Catherine Lohmann of the University of North Carolina

question 16

Multiple Choice

Scenario
Kenneth and Catherine Lohmann of the University of North Carolina explored the orientation or direction-finding abilities of loggerhead sea turtle hatchlings under varying magnetic conditions. Hatchlings were placed in a tank of water in a laboratory either in the natural magnetic field of the earth OR in a reversed magnetic field in which north and south were flipped. The researchers then measured the direction that the hatchlings swam. The experiments were carried out in the dark and at night since that is when most newly hatched turtles migrate from their sandy nests into the ocean.
-After concluding their experiments, the biologists probably

• A)announced that they had proven a new theory of animal migration.
• B)shared their data with colleagues to obtain feedback on the work.
• C)filed away the data in case anyone should ever ask about these experiments and then went on to other types of experiments.
