Positive feedback
During childbirth, the hormone oxytocin is released in response to uterine contractions. Oxytocin further stimulates more contractions, leading to the eventual delivery of the baby, which helps maintain homeostasis by expelling the fetus from the mother's body.
The hormone that stimulates contractions of the uterus in mammals is oxytocin. However, the story is probably rather more complex. In mice, for example, that had no cell membrane receptors for oxytocin, birth took place as usual. Oxytocin has a short peptide molecule consisting of just nine amino acids.
Negative feedback mechanisms work to maintain homeostasis by reversing a change in a system, while positive feedback mechanisms amplify and reinforce a change. An example of negative feedback is the regulation of body temperature – if body temperature rises, mechanisms kick in to lower it; whereas in positive feedback, childbirth contractions become stronger and more frequent to facilitate delivery.
No, positive feedback is rare, compared to negative feedback. This is because negative feedback is a self regulating cycle, so think of the regulation of heartbeats, breathing and amount of erythrocytes in the blood. The reason positive feedback doesn't occur that often is because it is not self regulating, the action of the cycle carry's on with the system. An example would be hypothermia. When your body goes below 37 degrees C, you will start to shiver to work up, if this does not work, your metabolic processes will start to slow down, you will become sleep, lethargic and lacking of energy, hence making it extremely difficult to bring heat back into the system to warm it up. Thus, the positive feedback can be a destructive mechanism. The easiest way to sum it up is that negative feedback is common as it tries to put a system back to its original equilibrium, positive feedback is rare because it is trying to make a new point for equilibrium. Hope this helps.
Depends on the animal, the parts match up, "the deeper the longer the other part", think of whales verus mice for example.

The adverb of forceful is forcefully.An example sentence is: "we will forcefully kick the door down".

Yes, labor contractions are an example of positive feedback. The contractions cause the release of oxytocin, which further stimulates increased contractions, resulting in the progression of labor. This cycle continues until the baby is born.
Yes, oxytocin release is an example of a positive feedback control mechanism. In response to stimuli such as childbirth or breastfeeding, oxytocin is released, which leads to stronger contractions in the uterus or milk let-down reflex, further stimulating more oxytocin release. This cycle reinforces and amplifies the initial stimulus.
Apostrophes are used to indicate contractions in language. For example, "it is" becomes "it's" with the apostrophe replacing the missing letter "i".
When you want to put two words together. Example: is+not= isn't
Yes, another example of a homophone with a contraction is "you're" (you are) and "your" (possessive form).

It depends on whether it is positive or negative feedback. Most biological organisms exhibit both negative and positive feedback, including humans. An example of positive feedback is contractions during childbirth. Negative feedback is blood sugar regulation based upon the release of insulin into the bloodstream at necessary times.
