Question

The Change that takes place in the body of the organism when a stimulus is provided is known as :
A. Adaptation
B. Response
C. Growth
D. None of the above

Answer 1

Hint:-Each and every organism is surrounded by an environment that keeps on changing itself. These changes may affect the organism both externally and internally. The changes may be physical, mechanical, or chemical that can affect the organism. When these changes affect the internal environment of the organism the behavior of the organism against these changes is also affected. To maintain the constant internal environment each living organism performs a process called, 'Homeostasis.”

Complete step-by-step solution:-
Adaptation enables the organism to survive in its habitat with a changing environment. It may be physiological, morphological, or behavioral. The organisms are adaptive evolved as the adaptations become genetically fixed over the evolutionary period.
Growth is referred to as the increase in mass or overall size of a tissue or organism or its parts. Once growth occurs it can not be reversed back so it is a permanent increase in the size of an organ or its parts or even of an individual cell.
All the living organisms or cells are capable of responding to a change in the environment (stimulus). Stimuli can be extremely variable and thus the response generated against that stimulus is also variable. A response that is generated when a stimulus is applied to an organism may support the effects of stimulus or opposes the effects of the stimulus. Every response in the body is under precise regulation mechanisms and is controlled by the highly developed systems of the body.
Thus, the correct answer is option B.

Note:- Various responses are generated to a stimulus like a biological response, electrical response, mechanical response, chemical response, or physical response. Out of all these responses, the electrical response generated inside the body or in a particular cell is the fastest generated. The biological responses vary from cell to cell based on its function. The electrical response precedes the biological response in a cell when a stimulus is applied.
