One function of gap junctions appears to be to cellular communication the activities of like cells in a particular area.
Connexins, membrane proteins that connect nearby cells, create tiny, fluid-filled tunnels known as connexons at gap junctions. Instead of being fused together like in tight junctions, the plasma membranes of gap junctions are separated by a very small intercellular gap (space).
Ions and tiny molecules can move from the cytosol of one cell to another through connexons. In avascular tissues like the cornea and lens of the eye, the transfer of nutrients and possibly wastes occurs through gap junctions.
Some of the chemical and electrical signals that control development and cell differentiation in a developing embryo travel through gap junctions.

They are similar in that both involve the growth of new organisms in an environment. However they differ in that primary succession occurs in a place where no life had been before, while secondary succession occurs in place where life had been before, but was destroyed

Answer:
Homeostasis
Explanation:
Homeostasis refers to maintaining the constant internal body conditions and mostly use the feedback loops to counteract any deviations from the narrow physiological range of several variants such as body temperature, blood glucose levels, etc.
For example, the human body maintains the internal body temperature around 37 degrees Celsius irrespective of the temperature of the surroundings.
When the body temperature rises above the standard range, the secretion of sweat and its evaporation to create the cooling effect is one of the several mechanisms that serve to lower down the body temperature.
Likewise, when the body temperature falls below the normal physiological range, increased heat production and prevention of heat loss are triggered by hypothalamus via autonomic nerve system to increase the body temperature again.
