Answer to Question 1

ANSWER:
The three fundamental functions of any information-processing system are receiving inputs, processing those input signals, and producing outputs that are based on the processed inputs. In humans, our sense organs perform the input functions by converting signals from the environment into nerve impulses. Once converted to nerve impulses by the sense organs, these nerve impulses are transmitted electrochemically from one neuron to another along the appropriate paths to the spinal cord and then on to particular parts of the brain specialized to receive those signals. Various specialized structures in the brain interpret those inputs into nerve impulses that control motor movements of various parts of the body, including those organs associated with speech. Except for some reflex signals that don't pass through the brain, the output signals flow electrochemically from neuron to neuron along paths from the brain through the spinal cord to the nerves that control muscle movements. The peripheral nervous system performs the initial input function and the final output function, and contains the sensory system and the motor system. The central nervous system consists of the brain and spinal cord, and performs the major processing functions.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
