Which of the following are responsible for the detection of changes in environment?
Correct answer: A. Receptors
- A. Receptors
- B. Neurons
- C. Effectors
- D. All of these
Explanation
Receptors detect changes in the environment and convert them into nerve impulses or other signals. Neurons transmit those signals and effectors carry out the response, so choosing either of them confuses detection with transmission or action.
