Input: Read this: Most annelids have a pair of coelomata (body cavities) in each segment, separated from other segments by septa and from each other by vertical mesenteries. Each septum forms a sandwich with connective tissue in the middle and mesothelium (membrane that serves as a lining) from the preceding and following segments on either side. Each mesentery is similar except that the mesothelium is the lining of each of the pair of coelomata, and the blood vessels and, in polychaetes, the main nerve cords are embedded in it. The mesothelium is made of modified epitheliomuscular cells; in other words, their bodies form part of the epithelium but their bases extend to form muscle fibers in the body wall. The mesothelium may also form radial and circular muscles on the septa, and circular muscles around the blood vessels and gut. Parts of the mesothelium, especially on the outside of the gut, may also form chloragogen cells that perform similar functions to the livers of vertebrates: producing and storing glycogen and fat; producing the oxygen-carrier hemoglobin; breaking down proteins; and turning nitrogenous waste products into ammonia and urea to be excreted.
Question: What are annelids' body cavities separated from each other by?

Output: vertical mesenteries

QUES: Beginning in the 18th century, the situation changed from more or less active persecution of religious services to a state of restricted toleration of other religions, as long as their services took place secretly in private churches.

QUES: The earliest Tibetan historical texts identify the Zhang Zhung culture as a people who migrated from the Amdo region into what is now the region of Guge in western Tibet. Zhang Zhung is considered to be the original home of the Bon religion. By the 1st century BCE, a neighboring kingdom arose in the Yarlung valley, and the Yarlung king, Drigum Tsenpo, attempted to remove the influence of the Zhang Zhung by expelling the Zhang's Bon priests from Yarlung. He was assassinated and Zhang Zhung continued its dominance of the region until it was annexed by Songtsen Gampo in the 7th century. Prior to Songtsan Gampo, the kings of Tibet were more mythological than factual, and there is insufficient evidence of their existence.
Where did the Zhang Zhung people migrate from?

ANS: Amdo region

Successful cultivation of cotton requires a long frost-free period, plenty of sunshine, and a moderate rainfall, usually from 600 to 1,200 mm (24 to 47 in). Soils usually need to be fairly heavy, although the level of nutrients does not need to be exceptional. In general, these conditions are met within the seasonally dry tropics and subtropics in the Northern and Southern hemispheres, but a large proportion of the cotton grown today is cultivated in areas with less rainfall that obtain the water from irrigation. Production of the crop for a given year usually starts soon after harvesting the preceding autumn. Cotton is naturally a perennial but is grown as an annual to help control pests. Planting time in spring in the Northern hemisphere varies from the beginning of February to the beginning of June. The area of the United States known as the South Plains is the largest contiguous cotton-growing region in the world. While dryland (non-irrigated) cotton is successfully grown in this region, consistent yields are only produced with heavy reliance on irrigation water drawn from the Ogallala Aquifer. Since cotton is somewhat salt and drought tolerant, this makes it an attractive crop for arid and semiarid regions. As water resources get tighter around the world, economies that rely on it face difficulties and conflict, as well as potential environmental problems. For example, improper cropping and irrigation practices have led to desertification in areas of Uzbekistan, where cotton is a major export. In the days of the Soviet Union, the Aral Sea was tapped for agricultural irrigation, largely of cotton, and now salination is widespread.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why is cotton grown as an annual crop?
Ah, so.. control pests

Question: Some risk factors for death include age, hemodynamic parameters (such as heart failure, cardiac arrest on admission, systolic blood pressure, or Killip class of two or greater), ST-segment deviation, diabetes, serum creatinine, peripheral vascular disease, and elevation of cardiac markers. Assessment of left ventricular ejection fraction may increase the predictive power. Prognosis is worse if a mechanical complication such as papillary muscle or myocardial free wall rupture occurs. Morbidity and mortality from myocardial infarction has improved over the years due to better treatment.
Try to answer this question if possible: Prognosis improves after what complication?
Answer: unanswerable

Question: Tiberius' brother Gaius was elected tribune in 123 BC. Gaius Gracchus' ultimate goal was to weaken the senate and to strengthen the democratic forces. In the past, for example, the senate would eliminate political rivals either by establishing special judicial commissions or by passing a senatus consultum ultimum ("ultimate decree of the senate"). Both devices would allow the Senate to bypass the ordinary due process rights that all citizens had. Gaius outlawed the judicial commissions, and declared the senatus consultum ultimum to be unconstitutional. Gaius then proposed a law which would grant citizenship rights to Rome's Italian allies. This last proposal was not popular with the plebeians and he lost much of his support. He stood for election to a third term in 121 BC, but was defeated and then murdered by representatives of the senate with 3,000 of his supporters on Capitoline Hill in Rome. Though the senate retained control, the Gracchi had strengthened the political influence of the plebeians.
Try to answer this question if possible: In what year was Gaius elected to office?
Answer:
123 BC
