Hormones: they are the chemicals of the endocrine system used to send messages to organs and tissue throughout the body
neurotransmitters: a chemical substance released at the end of a nerve fiber at the arrival of a nerve impulse, by diffusing across the synapse, which then causes the transfer of the impulse to another nerve fiber, etc.
Hormones and neurotransmitters are equally both similar and different in many ways. A characteristic that they both share, is that they are both forms of sending messages into the body. The only difference being, a neurotransmitter is sends signals to balance target cells, aka muscles or glands. Hormones send messages and signals throughout the body and organs.
It depends on what type of government the country is. Take an example, Great Britain (England, Britain, whatever it is called.) is a monarchy, which means that they have royal families... like how we have the president. (in the U.S at least) It can also be dependent on what the country decides to do, or the president decides. I hope this helps!
