Question

a breakdown in homeostatic regulation, leading to disease or dysfunction, can occur if:
negative feedback loops are functioning correctly to maintain stable internal conditions.
sensors accurately detect minor fluctuations around a set point.
an effector organ is damaged and can no longer respond appropriately to signals from the control center, even if the stimulus is detected.

Explanation:

Homeostasis relies on sensors, a control - center, and effector organs. If an effector organ is damaged and can't respond to control - center signals, homeostasis breaks down, leading to disease or dysfunction. Negative feedback loops maintaining stable conditions and sensors detecting minor fluctuations are normal and help maintain homeostasis.

Answer:

An effector organ is damaged and can no longer respond appropriately to signals from the control center, even if the stimulus is detected.
