which staement is true regarding the specificity of communication by the nervous system compared to the endocrine system​

The nervous system sends electrical signals while the endocrine system communicates through hormones.

Explanation:

Nerves are made up of very specialized cells, which send signals very quickly from tissue to the brain. The endocrine system is responsible for communicating using hormones, which have a more widespread effect. The effect of these hormones affects every cell they come into contact with, which can change how these cells functions. Cells use hormones to communicate with each other as well, as they are often separated by empty space.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
