The numbers of some receptors found in the brain may vary during the day by 50%.

  • All organisms have a natural circadian rhythm, which is one of the key distinguishing characteristics of organisms. They are present in most biochemical and molecular processes, from transcription of genes in the cell nucleus to cell cycle regulation, and are heavily involved in physiological and behavioral mechanisms.
  • The central circadian regulatory nucleus in mammals that responds to environmental light-dark cycles is known as the suprachiasmatic nucleus (SCN) and is located in the anterior hypothalamus of the brain.
  • A set of clock genes form a transcription-translation feedback loop at the SCN, a key mechanism of circadian rhythms. Although the SCN is essential for the generation of mammalian biological rhythms, it is not the only nucleus in which clock genes are expressed and regulated.

Therefore, the correct answer is 50%.
