Which of the following statements is not true about an animal's circadian rhythm? a. it's not influenced by genetics, only the time of day b. animals have special adaptations depending on whether they are nocturnal or diurnal c. it's influenced by genetics and the time of day d. it can be adjusted or overcome with time and effort

The correct answer is option A.

Explanation:

A circadian rhythm is a roughly day-night cycle or 24 cell cycle in the physiological processes of living organisms, including animals, plants, cyanobacteria, and fungi. These cycles are endogenously manufactured, although they can be influenced or effect by external hints such as temperature or sunlight.

The discoveries found that drosophila and Neurospora models have suggested the mechanism of circadian cycles and their importance to biology and disease are influenced by genetics and certain genes such as clock gene.
