Until recent history,extinctions have always happened gradually and on a small scale.
Explanation:
Extinction occur when environmental factors like natural disaster,habitat fragmentation,over exploitation,global change don't favor the survival of species thus gradually leads to extinction of species.
Some times human activity becomes the major problem for extinction.More over,poor reproduction,decline in population number and genetic inbreeding also leads to extinction.
99% of all species that exist on earth become disappeared.

Answer:
This is an example of Harrison's central nervous system working closely with his autonomic nervous system to give him energy and awareness to escape.
Explanation:
Harrison interprets the presence of the group of teenagers as an imminent danger and so he is on the run, which corresponds to a set of reactions that are triggered in the human body when a danger is around. At this point, the central nervous system and the subtonic nervous system are working together to get the adrenaline in Harrison's body to rise to a level that allows him to escape the group of teenagers. The central nervous system was then responsible for receiving and processing information that indicates to Harrison that he may be in danger. On the other hand, the autonomic nervous system is responsible for regulating the body's involuntary responses, being responsible for controlling various vital functions and at this time for the release of adrenaline in response to the dangerous situation.
These fibers provide vis- ceral motor (parasympathetic) innervation to the viscera. The only cranial nerves that transmit parasympathetic fibers are the oculomotor, facial, glossopharyngeal, and vagus nerves.
