Explanation:
As a characteristic of all living things, homeostasis relates most directly to which of the following biological themes?
A.) Interacting systems.
B.) Stability.
C.) Evolution.
D.) Scale and structure.
Correct: B.) Stability.
During homeostasis the body maintains a constant internal balance (stability) in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis.
Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

<h3>Meaning of Decibels</h3>
Decibels can be defined as the unit used by scientists to measure sound level.The values of Decibel ranges from a very low value to a very high value and the higher we get the more dangerous it is to our human ear.
