Answer:
The nuclear receptor superfamily comprises a large group of transcription factors that play a key regulatory role in development and homeostasis of multicellular organisms. A special feature of nuclear receptors is their ability to bind to condensed chromatin templates, which makes them important initiators of gene transcription. Moreover, the ability of nuclear receptors to sequentially recruit a variety of transcription factors and coregulators to target promoters and to orchestrate the whole process of gene transcription confirms their biological significance and stimulates intensive research and a high level of scientific interest in this field. In this review, we summarise current knowledge regarding the structure and function of nuclear receptors as principal regulators of gene expression. Emphasis is given to the molecular mechanisms of nuclear receptor-mediated transcriptional activation and repression including recent progress made in this area.
Sodium, potassium, chloride and calcium ions are important for establishing the resting potential of the cell. The sodium-potassium gradient is maintained by a pump which transports 2 potassium inside the cell and 3 sodium ions outside the cell.
Answer:
No they don't,they have to work together for an organ to function. they have to work together for the body to work alone

Answer: Friction
Explanation: Sir Isaac Newton, a soccer ball on the grass will stay where it is unless acted on by a force.
When a star is fusing iron in its core, it's still giving off insane amounts of energy. ... Iron cannot be fused into anything heavier because of the insane amounts of energy and force required to fuse iron atoms. The atomic structure of iron is very stable, more so than most other elements.
