Question
- A. Cells that detect stimuli
- B. Structures that bring about responses to restore optimum levels
- C. Coordination centres that process information
- D. Hormones that regulate body functions
Answer
The correct option is Structures that bring about responses to restore optimum levels. This answer is correct because it matches the approved learning objective to identify effectors, including muscles and glands, as structures that bring about responses to restore optimum levels in the subtopic Homeostasis.
Explanation
The correct option is Structures that bring about responses to restore optimum levels. Structures that bring about responses to restore optimum levels is correct because it directly supports the approved learning objective to identify effectors, including muscles and glands, as structures that bring about responses to restore optimum levels. This belongs to the subtopic Homeostasis within Homeostasis, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Homeostasis.
Common mistake
Misunderstanding Effectors
Students often confuse effectors with receptors, thinking that effectors detect stimuli instead of responding to them.
Remember that effectors are the structures that bring about responses to restore optimum levels, while receptors are responsible for detecting stimuli.
