Activity levels of the green iguana vary in cycles that are repeated every 24 hours. It is logical to assume that alteration in the intensity of incident light is the stimulus that controls these daily biological rhythms. But there is much evidence to contradict this hypothesis.

Q:Which of the following, if known, is evidence that contradicts the hypothesis stated above?

Choose an answer

The temperature of the green iguana varies throughout the day, with the maximum occurring in the late afternoon and the minimum in the morning

While some animals, such as the rabbit, are much more active during the day, others, such as moles, show greater activity at night

When animals are transported from one time zone to another, their daily biological rhythms adjust in a matter of days to the periods of sunlight and darkness in the new zone

Even when exposed to constant light intensity around the clock, some iguanas display rates of activity that are much greater during daylight hours than at night.
