reverse osmosis
Ques: Answer the following question given this paragraph: muscle cells of the uterus become more sensitive to its effects. Oxytocin is continually released throughout childbirth through a positive feedback mechanism. As noted earlier, oxytocin prompts uterine contractions that push the fetal head toward the cervix. In response, cervical stretching stimulates additional oxytocin to be synthesized by the hypothalamus and released from the pituitary. This increases the intensity and effectiveness of uterine contractions and prompts additional dilation of the cervix. The feedback loop continues until birth. Although the mother's high blood levels of oxytocin begin to decrease immediately following birth, oxytocin continues to play a role in maternal and newborn health. First, oxytocin is necessary for the milk ejection reflex (commonly referred to as "let-down") in breastfeeding women. As the newborn begins suckling, sensory receptors in the nipples transmit signals to the hypothalamus. In response, oxytocin is secreted and released into the bloodstream. Within seconds, cells in the mother's milk ducts contract, ejecting milk into the infant's mouth. Secondly, in both males and females, oxytocin is thought to contribute to parentnewborn bonding, known as attachment. Oxytocin is also thought to be involved in feelings of love and closeness, as well as in the sexual response. Q: What is continually released during childbirth through a positive feedback mechanism and prompts uterine contractions to fetal head toward the cervix? Choices: - hemoglobin - insulin - vasopressin - oxytocin A:
Ans: oxytocin

Answer the following question given this paragraph: Energy also constantly changes back and forth between kinetic and potential energy. Kinetic energy is the energy of movement. For example, a ball falling through the air has kinetic energy because it is moving ( Figure below ). The random motion of molecules is due to kinetic energy, and the driving force behind diffusion. Q: Energy constantly changes back and forth between kinetic and what type of energy? Choices: - practical - physical - mechanical - potential A:
(A).
potential
Ques:Answer the following question given this paragraph: The alchemists were never successful in changing lead into gold. But modern nuclear physics can accomplish this task. Lead is subjected to nuclear bombardment in a particle accelerator. A small amount of gold can be obtained by this process. However, the cost of the procedure is far more than the amount of gold obtained. So the dream of the alchemists has never (and will never) come true. Q: Which procedure helps modern nuclear physics convert lead into gold? Choices: - nuclear fission - matter fusion - evaporation - nuclear bombardment A:

Ans:nuclear bombardment
Ques: Answer the following question given this paragraph: Q: Many parasites have complex life cycles involving multiple ? Choices: - features - viruses - diseases - hosts A:
Ans:
hosts
