Question

In a negative feedback system, which one of the following statements is TRUE? Group of answer choices Homeostasis cannot be re-established until the effector is turned off. A sensor is not needed because the body anticipates the coming change. A sensor detects a stimulus, which in turn amplifies the original disturbance. The effector activates the sensor. Deviations from a desired condition are automatically detected and counteracted.

Answer 1

The correct answer is ¨Deviations from the desired condition are automatically detected and counteracted¨

Step-by-step 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
