Dopamine acts in the pineal gland, which is central to dictating the "circadian rhythm" in humans (the series of biological processes that enables brain activity to adapt to the time of the day). The pineal gland translates the light signals received by the retina through the synthesis of the hormone melatonin, which is produced and released at night and which helps to regulate the body's metabolic activity during sleep.
Another hormone, norepinephrine, is involved in regulating this synthesis and release of melatonin in the pineal gland. It was long believed that these norepinephrine receptors all acted independently of other proteins, but in the new study, researchers have discovered that this is not the case. In fact, the receptors collaborate with other dopamine receptors forming 'heteromers'.
nature and its cyclic behaviour.
The changing of seasons is cyclic in nature, with the cycle of spring, summer, fall, and winter repeating each year. Additionally, the water cycle, where water evaporates, condenses, and falls back to the Earth as precipitation, is another example of a cyclic process in nature.

The scientific method can be considered cyclic, as it involves a continuous loop of making observations, forming hypotheses, conducting experiments, analyzing data, and refining theories based on the results. This cyclical nature allows for the iterative nature of scientific inquiry and the advancement of knowledge.
A helicopter is controlled by the pilot using a combination of controls. These controls include cyclic for directional control, collective for altitude control, and pedals for yaw control. By manipulating these controls, the pilot can change the helicopter's position and orientation in the air.
Water is bidirectional process. It is cyclic in nature.

A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.

Yes, every subgroup of a cyclic group is cyclic because every subgroup is a group.
Meiosis is not cyclic; rather it is a linear process. It does not cycle.
