Answer:
The nervous system uses cell-communication by electrochemical signals that hormones, neurotransmitters or cytokines
Explanation:
Cell communication is vital to maintain internal environment thanks to homeostasis process which regulates the responses to internal and external stimulus. The functioning of cells depends on the electrochemical signals, these allows the communication and coordination among a group of cells of the tissue.
There are different type of loop-responses:
Negative Feedback Loops;
Reaction that causes a decrease in function, in response to some stimulus. The maintenance blood pressure, blood pH, oxygen/carbon dioxide balance, water balance (osmoregulation),calcium levels, among others are examples of negative feedback loops.
Positive Feedback Loops
Are involved in the amplification of the stimulus. D

Thus, using a soft wire brush with an electric drill is not appropriate since it could remove more material than the necessary from the posts.
