Answer 2

Reflex action - Reflex is an involuntary and sudden response to stimuli. It happens to be an integral component of the famed survival instinct.

Step-by-step explanation:

• Reflex action is a sudden and involuntary response to stimuli. It helps organisms to quickly adapt to an adverse circumstance that could have the potential to cause bodily harm or even death. Pulling our hands away immediately after touching a hot or cold object is a classic example of a reflex action.

• The event that proceeds a stimulus in organisms -

1. The first event begins with the receptor detecting a stimulus from a sensory organ. The stimulus could be in the form of pressure, temperature or chemicals.  
2. This is followed by the sensory neuron sending a signal to the relay neuron.  
3. The relay neuron then sends the signal to the motor neuron.  
4. The motor neuron sends a signal to the organ or a cell that acts to the stimuli called the effector.
5. Finally, the effector produces an immediate response, such as a knee-pull reaction.

• Examples of reflex action are: When light acts as a stimulus, the pupil of the eye changes in size.
