A sample is a random, unbiased selection out of a larger group. An independent variable is one that is changed as to see how it will affect the dependent variable in an experiment.
Hope that helped.
A person should eat energy bars and they should eat energy drinks because it supplies a good amount of carbohydrates (sugar) that can quickly convert inside your body to energy.
(Some good examples of energy drinks would be the brand 'Gatorade')
I am not so sure what exact brand of energy bars to eat, but I know for a fact that each energy bar contains carbohydrates, so probably any energy bar would work. :)

Answer:
How is the endocrine system related to the nervous system in terms of its regulatory activity?
For one, the endocrine system uses chemical signaling (hormones, produced by glands) while the nervous system uses electrical signaling (neural impulses). The signal transmission of the nervous system is fast because neurons are interconnected, but the functions are more short-lived.
Explanation:
Most peripheral nerves are nerves outside the brain and the spinal cord, carrying both sensory and motor impulses. The peripheral nervous system is one of the two components of the nervous system, the other part is the central nervous system. Peripheral nerves are classified into motor, sensory and autonomic nerves.
