Answer:
The correct answer is ¨Deviations from the desired condition are automatically detected and counteracted¨
Explanation:
The negative feedback is a type of control system that inhibits the signals that give arise to the disturbances o deviation.
This kind of response is typical in metabolism, for example in amino acid biosynthesis, high concentration of the product inhibits the first steps of the route.
That means in a negative feedback, the efector inhibits the sensor, so this kind of systems regulates itself, finishing the signaling process.
Other options to answer this question correspond to other types of control systems. For example "A sensor is not needed because the body anticipates the coming change" correspond to feed forward anticipation and "The effector activates the sensor" is characteristic of positive feedback
