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 a 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 variable being tested in this experiment?
a) time of hatching
b) time of day
c) magnetic field
d) amount of light

What happens as electrons move along the chain of molecules known as the electron transport chain? they gain energy, which causes atp molecules to lose phosphate groups. they gain energy, which causes h *ions to join with oxygen to produce water. they lose energy, which is then used by the cell to make atp. they lose energy, which is then used to break down atp.
