more.
The release of oxytocin leads to increased contractions which produce more oxytocin. thus option B is correct.
What do you mean by the positive feedback mechanism?
A system for positive feedback In reaction to an output variation, homeostasis is a mechanism that leads the output to fluctuate even more in the direction of the initial deviation. A positive feedback system amplifies errors and affects the state of the output.
Oxytocin has the effect of imitating more contractions, and so more Oxytocin is released as a result! It's a never-ending cycle of rising contractions and hormone levels to help push the baby.

what dose natural selection lead to
Hi!Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.
Answer:
Evolution
Explanation:
When natural selection occurs, more environmentally favorable traits are being passed on to offspring. As time goes by, more members of the population possess this trait until it's widespread amongst the species. This can even lead to speciation, the creation of a new species. This could also be the answer to your question. This process describes evolution, the process in which favorable and heritable traits are passed on throughout the generations and change the makeup of the species.

Where two plates glide past one another is known as a transform plate boundary. A transform fault is the fracture zone that creates the transform plate boundary.
Because the sense of movement is in the opposite direction, transform faults can be recognized from ordinary strike-slip faults (see illustration). A transform fault develops between two separate plates that are moving away from the spreading center of a divergent plate boundary. A strike-slip fault is a straightforward offset.
