Question

which of the following is an example of positive feedback?
overeating at thanksgiving
spooking cattle
breathing

Explanation:

Positive - feedback in a biological or general systems context is a process where the output of a system amplifies the system. None of these are typical examples of positive - feedback. However, overeating at Thanksgiving can be seen as a form of positive - feedback in a behavioral sense where the enjoyment of food (input) leads to more eating (amplified output). Spooking cattle is a one - time event and not a feedback loop, and breathing is a homeostatic (negative - feedback regulated) process.

Answer:

overeating at thanksgiving
