In what way do the nervous and endocrine systems differ in a way
Simora [160]

The nervous system communicates through electrical impulses and the communication is very fast. It works in a relay fashion, from point to point comparable to the way the old telephones systems used to work.

The endocrine system communicates by chemical signals via the bloodstream. Hormones are secreted into the blood and extra cellular fluids, then transported to target cells, which must bear a receptor to be able to bind to a specific hormone, and respond. 

Hormones are chemical messengers secreted into blood or extracellular fluid that affect the function of other cells.

Endocrine communication is not quite as fast as the nervous system communication

All of the following factors contribute to the differences in complex trait risk predictions between different laboratories, EXC
horsena [70]

Answer:

different assessments of environmental factors

Explanation:

In humans, for predicting the future phenotype of any individual, the PSR is used.

A trait may be defined as the state of a character that is a distinct variation of the phenotypic characteristic of any organism.

The following factors contributes to the differences in the complex trait risk predictions in the different laboratories :

-- differing methods of the combining risk from the multiple genetic variants.

-- genotyping of the different variants.

-- selection of the different genetic variants for such risk determination.

Thus the factor which does not contribute is :

"different assessments of the environmental factors."
