Answer the following question given this paragraph: El Nino and La Nina bring about dramatic changes in climate for a year or two. In some locations, one brings rain and the other brings drought. In California, for example, El Nino years are full of snow and rain. La Nina years tend toward drought. These variations can bring tremendous changes to living creatures. Humans are also affected; for example, erosion from storms may be very high some years. Q: What kind of weather change do la nina years usually bring? Choices: - heat - Mass amounts of snow - moisture - drought A:
drought

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:
(Answer)
oxytocin
