Dawn has been feeling very stressed about being pregnant, so she started having a glass of wine and a cigarette to her calm down. but the baby seems to get agitated and move around when she drinks. this makes dawn more stressed, so she ends up having another glass of wine and a couple cigarettes to ease her nerves. what is occurring through this process?

A positive feedback loop.

Explanation:

In the example given in the question, there's a cause and effect relationship between Dawn's drinking/smoking and the baby's reactions. It can be clearly seen that the consequence of the drinking/smoking action in turn increases the amount of said action through a positive feedback loop.

I hope this answer was helpful.
