Few other cycles in nature are same as water cycle. These are carbon cycle, nitrogen cycle etc.
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.
Inorganic carbon includes carbon dioxide (CO2) and carbonate ions (CO3 2-) found in the atmosphere, oceans, and rocks. These constituents play a crucial role in the carbon cycle and maintaining Earth's balance.
Positive feedback amplifies a particular response, which can be helpful in blood clotting to enhance the formation of a clot at the site of injury. However, in regulating body temperature, positive feedback would cause an endless cycle of increasing temperature, as the response would continually stimulate further warming without bringing the body back to equilibrium. Negative feedback is more suitable for regulating body temperature as it helps maintain homeostasis by reversing deviations from set points.
Gonadotropin release is primarily regulated by negative feedback mechanisms. In both males and females, sex hormones (like testosterone and estrogen) inhibit the secretion of gonadotropin-releasing hormone (GnRH) from the hypothalamus and luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland. However, during specific phases of the menstrual cycle, estrogen can induce a positive feedback loop leading to a surge in LH, which triggers ovulation. Overall, the predominant regulatory mechanism for gonadotropin is negative feedback.

The menstrual cycle involves both positive and negative feedback mechanisms. The follicular phase primarily utilizes negative feedback, where rising estrogen levels inhibit further production of follicle-stimulating hormone (FSH). In contrast, the surge in luteinizing hormone (LH) that triggers ovulation is an example of positive feedback, where increasing estrogen levels from the developing follicle stimulate further LH release. Thus, the menstrual cycle is a complex interplay of both feedback types.
The question almost states itself. Without positive feedback, there can be no oscillation (at least of a steady-state type). The feedback must be applied at an appropriate part of the oscillatory cycle, as well as at the appropriate level.

Positive feedback loop in which each force strengthens the others, creating a cycle of reinforcement.
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.
The melting of Arctic ice is an example of positive feedback. As the ice melts, it exposes more dark ocean water, which absorbs more heat from the sun, leading to further warming and more ice melt. This cycle reinforces and amplifies the initial warming trend.
