Question

When women are in labor, the uterus contracts more and more strongly by the actions of a peptide hormone messenger. This scenario is an example of.. * 1 point a negative feedback loop. a positive feedback loop. signal transduction immediately changing gene expression in its target cells. the key role of the anterior pituitary gland in regulating uterine contraction.

Answer 1

Answer:

The correct answer is -  a positive feedback loop

Explanation:

Oxytocin is a peptide hormone that is released during labor in women which contracts the uterus and n increase of the oxytocin causes more release of oxytocin hormone to increase the contraction more strongly.

Oxytocin shows a positive feedback loop as its release leads to more of the oxytocin release by stimulates its more release. Most of the hormones show negative feedback release.
