Answer:
The best answer to the question: If every gene has a tissue-specific and signal-dependent transcription pattern, how can such a small number of transcriptional regulatory proteins generate a much larger set of transcriptional patterns? Would be:
Because transcriptional regulators, which are the ones responsible for initiating, and stopping, transcription of RNA into protein, often work in pairs, one goes with the other, and thus increase the regulatory capabilities over gene expression so that the genes translated into RNA and then transcribed into aminoacids in protein chains, actually code for the correct protein types.
These regulators will both stand, as appropriate, on a specific gene to promote its transcription, or prevent it, depending on the different signaling mechanisms received.
Answer:
Sympathetic Nervous System.
Explanation:
Sympathetic nervous system is one of the parts of Autonomic nervous system and the other part is Parasympathetic nervous system.
As a whole the autonomic nervous system controls the unconscious responses of our body.
The main function of the Sympathetic nervous system is to stimulate the 3F response of the body. Here 3F refers to Fight, Flight and Freeze. Adrenal gland is stimulated by this system which secretes adrenaline. Due to the effect of adrenaline heart neat increases, blood pressure increases, pupils dilate, sweat glands are activated, peristalsis in the gut is inhibited, and kidney secretion increases.

Explanation:
According to the research done by Dr. Patricia Kuhl of the University of Washington in Seattle and colleagues at Stockholm University in Sweden, the Massachusetts Institute of Technology and the University of Texas in Austin, babies can perceive and learn the basics sounds of their language when they are 6 months old whereas before this study, it was suggested that they gained this ability when they are around 1 year old. I hope this answer helps.
