Question

Biological systems react to stimuli, for example hot conditions. The reaction starts with sensors, followed by controls, and then effectors. Match the components of a rding to this basic model by matching the number (1,2,3) to the appropriate location in the feedback loop (A,B,C)

Answer 1

I don’t have the diagram or the list of what 1, 2, 3 and A, B, C label—could you upload or paste it? Without the image I can’t be certain which number belongs to which position.

Meanwhile, here’s how to identify and match them yourself:

- Sensor (receptor): detects the stimulus (e.g., thermoreceptors in skin or hypothalamus that sense heat). On a diagram this is the element that receives the input from the environment.
- Control (integrator): compares the sensor input to a set point and issues commands (e.g., the hypothalamus acting as the “thermostat”). On a diagram this is the central box that receives the sensor signal and sends instructions to effectors.
- Effector: carries out the response (e.g., sweat glands, cutaneous vasodilation, or behavioral responses). On a diagram this is the element that produces the corrective action.

If in your diagram A = sensor, B = control, C = effector, then the matching is:
1 → A, 2 → B, 3 → C.

If you paste or upload the specific figure/labels I’ll give the exact mapping.
