Give a scientific reason: Reflex action plays a significant role in animals.

(N/A) Reflex action occurs through reflex centers of the brain or spinal cord.
It is a very fast,involuntary response that occurs without conscious effort from the animal.
Such actions serve as a defense mechanism against harmful stimuli to protect the animal.
For example,when an animal touches a hot surface,the immediate withdrawal of the limb prevents tissue damage.
If reflex action did not occur,animals would be highly susceptible to injury; therefore,reflex action is protective in nature.
