Positive feedback in a system is a benefit for the entire system

Answer: Option B

<u>Explanation:</u>

The positive mechanism is a stimuli that the body exhibits when in time of need which actually benefits the entire system. When required the positive feedback runs to rescue and neutralize the effect caused by the negative impact which paves a way to maintain equilibrium throughout the body.

Many examples can be cited for this like blood clotting, during labor and even in ripening of fruits. Positive and negative feedback work hand in hand to maintain homeostasis in place. Positive feedback is required to enhance the system while the negative feedback is to inhibit the activity.

In terms of communication, information is expressed either as the content of a message or through direct or indirect observation. That which is perceived can be construed as a message in its own right, and in that sense, information is always conveyed as the content of a message.
