Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Stimulus ____
A
A change that prompts an action-the cause
B
The ability to maintain a stable internal environment (type of equilibrium or balance)
C
How an organism reacts to a change and results in a change in behavior-the effect
D
Constant and balanced environment
Explanation: 

Detailed explanation-1: -In physiology, a stimulus is a detectable change in the physical or chemical structure of an organism’s internal or external environment. The ability of an organism or organ to detect external stimuli, so that an appropriate reaction can be made, is called sensitivity (excitability).

Detailed explanation-2: -A stimulus causes an action or response, like the ringing of your alarm clock if you didn’t sleep through it. Stimulus is a word often used in biology-something that causes a reaction in an organ or cell, for example.

Detailed explanation-3: -The ability of an organism to respond to external stimuli is called sensitivity. For example, Plants grow towards light(external stimuli) sources, and if the direction of light is changed, the plant will also change its direction of growth to accommodate for survival. So, the correct answer is ‘Sensitivity’.

Detailed explanation-4: -1) In classical conditioning, the conditional behavior (CR) is triggered by the particular stimulus (CS) and is therefore called an elicited behavior.
