Problem: Please answer a question about the following article about Annelid:
Feeding structures in the mouth region vary widely, and have little correlation with the animals' diets. Many polychaetes have a muscular pharynx that can be everted (turned inside out to extend it). In these animals the foremost few segments often lack septa so that, when the muscles in these segments contract, the sharp increase in fluid pressure from all these segments everts the pharynx very quickly. Two families, the Eunicidae and Phyllodocidae, have evolved jaws, which can be used for seizing prey, biting off pieces of vegetation, or grasping dead and decaying matter. On the other hand, some predatory polychaetes have neither jaws nor eversible pharynges. Selective deposit feeders generally live in tubes on the sea-floor and use palps to find food particles in the sediment and then wipe them into their mouths. Filter feeders use "crowns" of palps covered in cilia that wash food particles towards their mouths. Non-selective deposit feeders ingest soil or marine sediments via mouths that are generally unspecialized. Some clitellates have sticky pads in the roofs of their mouths, and some of these can evert the pads to capture prey. Leeches often have an eversible proboscis, or a muscular pharynx with two or three teeth.
What part of a polychaete can be everted?
A: pharynx
Problem: Please answer a question about the following article about Szlachta:
In the Kingdom of Poland and later in the Polish-Lithuanian Commonwealth, ennoblement (nobilitacja) may be equated with an individual given legal status as a szlachta (member of the Polish nobility). Initially, this privilege could be granted by monarch, but from the 1641 onward, this right was reserved for the sejm. Most often the individual being ennobled would join an existing noble szlachta clan and assume the undifferentiated coat of arms of that clan.
What clan was given the privileged of enoblement?
A: szlachta clan
Problem: Please answer a question about the following article about Israel:
The city of Jerusalem is of special importance to Jews, Muslims and Christians as it is the home of sites that are pivotal to their religious beliefs, such as the Old City that incorporates the Western Wall and the Temple Mount, the Al-Aqsa Mosque and the Church of the Holy Sepulchre. Other locations of religious importance in Israel are Nazareth (holy in Christianity as the site of the Annunciation of Mary), Tiberias and Safed (two of the Four Holy Cities in Judaism), the White Mosque in Ramla (holy in Islam as the shrine of the prophet Saleh), and the Church of Saint George in Lod (holy in Christianity and Islam as the tomb of Saint George or Al Khidr). A number of other religious landmarks are located in the West Bank, among them Joseph's Tomb in Nablus, the birthplace of Jesus and Rachel's Tomb in Bethlehem, and the Cave of the Patriarchs in Hebron. The administrative center of the Bahá'í Faith and the Shrine of the Báb are located at the Bahá'í World Centre in Haifa; the leader of the faith is buried in Acre. Apart from maintenance staff, there is no Bahá'í community in Israel, although it is a destination for pilgrimages. Bahá'í staff in Israel do not teach their faith to Israelis following strict policy. A few miles south of the Bahá'í World Centre is the Middle East centre of the reformist Ahmadiyya movement. Its mixed neighbourhood of Jews and Ahmadi Arabs is the only one of its kind in the country.
What incorporates the Western Wall and the Temple Mount?
A: Old City
Problem: Please answer a question about the following article about Gene:
Although the number of base-pairs of DNA in the human genome has been known since the 1960s, the estimated number of genes has changed over time as definitions of genes, and methods of detecting them have been refined. Initial theoretical predictions of the number of human genes were as high as 2,000,000. Early experimental measures indicated there to be 50,000–100,000 transcribed genes (expressed sequence tags). Subsequently, the sequencing in the Human Genome Project indicated that many of these transcripts were alternative variants of the same genes, and the total number of protein-coding genes was revised down to ~20,000 with 13 genes encoded on the mitochondrial genome. Of the human genome, only 1–2% consists of protein-coding genes, with the remainder being 'noncoding' DNA such as introns, retrotransposons, and noncoding RNAs.
What percentage of the human genome consists of protein coding genes?
A:
1–2%
