Answer the following question given this paragraph: A common sign that labor will be short is the so-called "bloody show. " During pregnancy, a plug of mucus accumulates in the cervical canal, blocking the entrance to the uterus. Approximately 12 days prior to the onset of true labor, this plug loosens and is expelled, along with a small amount of blood. Meanwhile, the posterior pituitary has been boosting its secretion of oxytocin, a hormone that stimulates the contractions of labor. At the same time, the myometrium increases its sensitivity to oxytocin by expressing more receptors for this hormone. As labor nears, oxytocin begins to stimulate stronger, more painful uterine contractions, whichin a positive feedback loopstimulate the secretion of prostaglandins from fetal membranes. Like oxytocin, prostaglandins also enhance uterine contractile strength. The fetal pituitary also secretes oxytocin, which increases prostaglandins even further. Given the importance of oxytocin and prostaglandins to the initiation and maintenance of labor, it is not surprising that, when a pregnancy is not progressing to labor and needs to be induced, a pharmaceutical version of these compounds (called pitocin) is administered by intravenous drip. Finally, stretching of the myometrium and cervix by a full-term fetus in the vertex (head-down) position is regarded as a stimulant to uterine contractions. The sum of these changes initiates the regular contractions known as true labor, which become more powerful and more frequent with time. The pain of labor is attributed to myometrial hypoxia during uterine contractions. Q: Oxytocin, which stimulates the contractions of labor, is a type of what? Choices: - metabolite - inhibitor - steroid - hormone A:
hormone
Answer the following question given this paragraph: Floods may occur when deep snow melts quickly in the spring. More often, floods are due to heavy rainfall. Floods happen when rain falls more quickly than water can be absorbed into the ground or carried away by rivers or streams. Q: What occurs when rain falls more quickly than water can be absorbed into the ground or carried away by rivers or streams? Choices: - typhoons - greenhouse effect - landslides - floods A:
floods
Q: Answer the following question given this paragraph: Rolling friction is friction that acts on objects when they are rolling over a surface. Rolling friction is much weaker than sliding friction or static friction. This explains why most forms of ground transportation use wheels, including bicycles, cars, 4-wheelers, roller skates, scooters, and skateboards. Ball bearings are another use of rolling friction. You can see what they look like in the Figure below . They let parts of a wheel or other machine roll rather than slide over on another. Q: What is friction that acts on objects while it is rolling over a surface called? Choices: - blowing friction - opposing friction - surface friction - rolling friction A:
A: rolling friction
Question: Answer the following question given this paragraph: Bronchitis is an inflammation of the bronchi, the air passages that conduct air into the lungs. The bronchi become red and swollen with infection. Acute bronchitis is usually caused by viruses or bacteria, and may last several days or weeks. It is characterized by a cough that produces phlegm, or mucus. Symptoms include shortness of breath and wheezing. Acute bronchitis is usually treated with antibiotics. Q: What is the usual treatment for acute bronchitis? Choices: - surgery - physical therapy - pesticides - antibiotics A:
Answer: antibiotics

Answer the following question given this paragraph: Understanding and curing genetic diseases is the ultimate goal of human geneticists. As discussed in the Human Genetics: Diagnosis and Treatment (Advanced) concept, gene therapy is the insertion of a new gene into an individual's cells and tissues to treat a disease, replacing a mutant disease-causing allele with a normal, non-mutant allele. Of course, the findings of the Human Genome Project are significant in determining the disease-causing alleles. Geneticists must know which are mutant alleles and which are non-mutant or "normal" alleles. They must also be able to identify alleles that are not just associated with a particular disease phenotype, but cause a disease phenotype. And of course, scientists must develop and test the technology to replace mutant alleles. Q: For geneticists, the findings of what massive undertaking are significant in determining disease-causing alleles? Choices: - human produce project - Visible Human Project - human organisms project - human genome project A:
**Answer**
human genome project

Red blood cells, white blood cells, and platelets are all produced in the red marrow. Q: Red blood cells, white blood cells, and platelets are all produced where? Choices: - in yellow marrow - in synovial fluid - in collagen - in red marrow A:
