How do the nervous system and endocrine system differ in regards to managing homeostasis?
Citrus2011 [14]
Hello friend!!
The biggest difference between the two is that the nervous system uses electrical impulses to send signals through neurons, whereas the hormonal system uses chemical messengers transported into blood plasma to target cells. 
Transmission by the nervous system is short-lived but quick, whereas transmission by the hormonal system is long-lasting but takes much longer. Hene, communication is faster when using the nervous system. 
In the nervous system, responses are localised - whereas in the hormonal system, they are widespread. Responses are often permanent in the hormonal system, but temporary and reversible in the nervous system.

DNA, in the nucleus carries the genetic code for making proteins in ribosomes. In the diagram, B, represents the proteins produc
soldi70 [24.7K]

A: ribosome  C: translation

During transcription, the two DNA strands unwind and separate. Free ribonucleotides combine to the corresponding bases in the template strand, which is one of the separated DNA strands. These ribonucleotides will form a mRNA, which can leave the nucleus and enter the cytoplasm.

In cytoplasm, mRNA will be translated into protein by ribosomes. During translation, the mRNA inside the ribosome will be attached to tRNA molecules, which will then attract specific amino acids. Different tRNA molecules bond with the corresponding segments of the mRNA and different amino acids will be joining together by peptide bond. A protein is then produced.
