Final answer:
Negative feedback loops help maintain stability by counteracting changes, whereas positive feedback loops amplify changes. Examples include temperature regulation (negative) and childbirth (positive).
Step-by-step explanation:
The question asked is referring to the concepts of positive feedback loops and negative feedback loops in the context of biological systems.
Negative feedback loops are mechanisms that help maintain a system's stability by reducing the intensity of changes, effectively maintaining a system's unique ways of regulating itself. For example, the regulation of body temperature and blood sugar levels are classic cases of negative feedback mechanisms.
In contrast, positive feedback loops amplify changes or deviations, thus promoting a process to continue in the same direction. An example of a positive feedback loop is the release of oxytocin during childbirth, which intensifies the contractions until the baby is born.
