Final answer:
Positive and negative feedback loops in biology
Step-by-step explanation:
Differentiation between Positive and Negative Feedback Loops
In biology, feedback loops are mechanisms that regulate a biological system by responding to a change. Two types of feedback loops are positive and negative feedback loops.
Positive Feedback Loop
A positive feedback loop amplifies or reinforces a change in a biological system. An example is the process of blood clotting. When a blood vessel is damaged, platelets release chemicals that attract more platelets, leading to the formation of a blood clot.
Negative Feedback Loop
A negative feedback loop counteracts a change in a biological system, bringing it back to its original state. An example is the regulation of body temperature. When the body temperature increases, sweat is produced to cool down the body, bringing the temperature back to normal.
