A scientist believes that she has found a new life form. Which of the following
conditions is not considered essential in determining whether the new life form is alive?
✓ The creature is multicellular
You try to start your car, but it does not start. Which of these is a prediction?
✓ If I recharge the battery, then my car will start.
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.
What is the independent variable being tested in this experiment?
✓ Magnetic field

What is the dependent variable in this experiment?
✓ The direction that turtles swim, with or against the magnetic field.
