The correct answer is positive fee back.

Positive feedback is termed as the process which appears in a feedback loop whereby small disturbance on a system may leads to increase in magnitude.

There is exponential growth when the side of equilibrium increases in oscillation. Positive feedback is used in digital electronics which moves voltage away from intermediate voltage.

Another example of positive feedback is thermal runaway and its work is to destroy semiconductor junctions. In chemical reaction the work of positive feedback is to increase the rate of reaction.

<span>Positive feedback</span><span>

There are two types of feedback mechanisms
Positive feedback heightens the intensity
Negative feedback lowers the intensity

These all serve to maintain homeostasis. Homeostasis is the state where the internal and external part of the body maintains and establishes balance and equilibrium. </span>

what happens when a cell is subjected to a solution where the water concentration is equal to that inside a cell?(isotonic solut

astra-53 [7]

When a cell is subject to a solution that is equal in water concentration as inside the cell, the movement of water via a process called osmosis will equalize and the solution is said to be isotonic to the cell. That means the amount of water entering the cell from the solution will equal the water exiting the cell; no net water movement.
