Nervous system is much more systematic because the impulses are passed as messages through the neurons. The process and the response are very rapid. Endocrine system, on the other hand, is wide range. The process is slow and the effect is long-lasting.
I want to Say A - I searched google and it said that Archaea has something called membrane lipid bonding, ( which is oils and fat ) I didn't see anything about nucleus, size, or cell wall.
Hope this helped!
