Homeostasis refers to any process, such as negative feedback, that living
things employ to maintain stable conditions indispensable for survival, and
which arises from balances between forces and factors mutually influencing each
Line other. Disturbance, or departure from equilibrium is of more consequence than
(5) negative feedback: systems cannot correct themselves without straying. A car
and its driver, for instance, can be regarded as a homeostatic system seeking to
keep the car moving on track. Thus, if the car skids, the driver automatically
responds by quickly steering the wheel in the opposite direction, but such
abrupt negative feedback usually overcorrects. Likewise, if the magnitude of
(10) correction is commensurate with the disturbance that triggered it, the
correction may become an impressed change in the direction opposite to that of
the original disturbance. Each feedback is of lesser magnitude than the last, so
that as the oscillations of the system dampen, negative feedback achieves its
goal in both artificial and natural systems.
According to the passage, all of the following are true concerning the process of negative feedback EXCEPT
选项
A、By diminishing errors, negative feedback allows systems to correct themselves.
B、Negative feedback always arises out of a system where several factors are interacting.
C、Negative feedback sometimes causes a disturbed system to over-correct, resulting in an impressed change opposite to the original disturbance.
D、Negative feedback is less important, on the whole, than departure from equilibrium.
E、Ideally, negative feedback gradually diminishes, allowing a system to find its desired course.
