Question

Which of the following best characterize the simple response to simple stimuli?

• A. Simple reflex
• B. Complex reflex
• C. Fixed action patterns
• D. Behavioral cycles
• E. Environmental rhythms

Answer 1

The correct option is A Simple reflex

• A stimulus is anything that can be perceived by a given organism including sight, sound, touch, smell, taste, etc.
• A response is generally characterized as the behaviour proximal to the stimulus. So if a bell rings and a person jumps the stimulus is the bell and the response is the jump.
• The ability of an organism or organ to respond to external stimuli is called sensitivity. When a stimulus is applied to a sensory receptor, it normally influences by a simple reflex. Hence, Simple reflex is best to characterize the simple response to simple stimuli.

So, the correct answer is 'Simple reflex'.
