Answer:
Positive feedback is used to build more contractions.
Explanation:
Positive feedback mechanism in humans is also observed during childbirth which is induced by the pressing of the ovarian wall by the baby.
The pressing sensation is passed to the brain via different nerves, and in response, the brain stimulates the pituitary to produce oxytocin.
Oxytocin is responsible for the contractions of the uterine muscles which cause the movement of the fetus towards the cervix, further increasing the stimulus.
The positive feedback loop continues until the baby is born.
Answer:
Cervix.

The process of the child birth and the delivery of the baby from the mother's womb shows the labor. The labor process is completely divided into the four stages.
The passageway is the first stage of labor. This is further divided into the early labor and active labor. The vagina and cervix are the main component of the first phase and consist of the soft tissue. The birth canal is formed by the together of the vagina and cervix.
Thus, the answer is cervix.
Answer:
Because salt is soluble in water, salt applied to such surfaces dissolves. Liquid water has what is known as a high dielectric constant, which allows the ions in the salt (positively charged sodium and negatively charged chlorine) to separate.
Explanation:
Answer:
The root system is always adventitious. The stem is either underground or aerial. The leaves may be microphylls or megaphylls. Their other common characteristics include vascular plant apomorphies (e.g., vascular tissue) and land plant plesiomorphies (e.g., spore dispersal and the absence of seeds).
Explanation:
Answer:The tails
Explanation:
they face inward on the plasma membrane and are hydrophobic because they repel water.
