Final answer:
Feedback loops in biology help maintain internal conditions while external conditions may be changing. This process is known as homeostasis.
Step-by-step explanation:
Feedback loops in biology help maintain internal conditions while external conditions may be changing. This process is known as homeostasis. Homeostasis is the ability of an organism to maintain a stable internal environment despite changes in the external environment.
For example, if the external temperature rises, the body responds by sweating to cool down and maintain a constant internal body temperature. If the external temperature drops, the body responds by shivering to generate heat.
Other examples of homeostasis include maintaining a stable pH level, blood sugar level, and water balance in the body. Feedback loops, involving sensors, control centers, and effectors, play a crucial role in regulating these internal conditions.
