Leukocytes, more commonly known as white blood cells are essential in fighting disease.<span />
The pendulum weight swings side to side. It has maximum kinetic energy when it is mid-swing, closest to the ground. At this point it swings back up. Its kinetic energy is transformed to gravitational potential energy. Its maximum gravitational potential energy occurs when it is at its maximum height, when it stops, just before swinging to the other side.
Answer:
Option A) Oxytocin causes the uterus to contract ,further stimulating the receptors that signal the brain to release oxytocin.!
Explanation:
Positive feedback is a mechanism in which the output of a process increases the magnitude of the process which caused that output and this loop continues.
The most common example of the Positive Feedback Mechanism is the child birth. During child birth, the child pushes on the walls of uterus. This stimulates the pressure receptors which send signals to brain to release oxytocin. This oxytocin causes the wall of uterus to contract further, which is again detected by the pressure receptors. This sends signals to the brain again and this process continues in this loop.
The right option is; D. Vasectomy for her male partner
Vasectomy for her male partner is the contraceptive method that would be most beneficial for a female who wishes to avoid side effects or surgery.

This method is very effective as it prevent sperm from entering a female and permanently protects against pregnancy. Vasectomy is beneficial for females because the surgery is performed on male and females do not experience any side effect.
