Userkaf's pyramid is part of a larger mortuary complex comprising a mortuary temple, an offering chapel and a cult pyramid as well as separate pyramid and mortuary temple for Userkaf's wife, queen Neferhetepes. Userkaf's mortuary temple and cult pyramid are today completely ruined and difficult to recognize. The pyramid of the queen is no more than a mound of rubble, with its funerary chamber exposed by stone robbers.The complex is markedly different from those built during the 4th Dynasty (c. 2613–2494 BC) in its size, architecture and location, being at Saqqara rather than Gizah. As such, Userkaf's pyramid complex could be a manifestation of the profound changes in the ideology of kingship that took place between the 4th and 5th dynasties, changes that may have started during the reign of Userkaf's likely immediate predecessor, Shepseskaf. Some 1500 years after its construction, the pyramid complex was restored under Ramses II. During the much later Saite period (664–525 BC), it was used as a cemetery.

Question: Who succeeded Shepseskaf as king of ancient Egypt?
Answer: Userkaf

Question: Userkaf's pyramid was next to another pyrimad belonging to whom?
Answer: queen Neferhetepes
While the forward part of the angel shark's body is broad and flattened, the rear part retains a muscular appearance more typical of other sharks. The eyes and spiracles are on top and the five gill slits are on its back. Both the pectorals and the pelvic fins are large and held horizontally. There are two dorsal fins, no anal fin and unusually for sharks, the lower lobe of the caudal fin is longer than the upper lobe. Most types grow to a length of 1.5 m (5 ft), with the Japanese angel shark, known to reach 2 m. While they may grow very large, some angel sharks develop spinal abnormities which include scoliosis.  Landings of Pacific Angel Shark increased through the mid-1980s and reached over 1125 tonnes in 1986, becoming the shark species with the highest total reported landings off the US West coast that year. Angel sharks possess extensible jaws that can rapidly snap upwards to capture prey and have long, needle-like teeth. They bury themselves in sand or mud lying in wait for prey, which includes fish, crustaceans and various types of mollusks. They are ovoviviparous, producing litters of up to 13 pups. Pacific Angel Shark pups are born from March to June in deep water — generally 180 to 300 feet (55 and 90 metres) — possibly to protect the tiny pups from predators.Angel Sharks usually reside in depths of 1–200 m and can be seen on muddy or soft bottom substrata where they can easily blend in

Question: What does a typical diet of a Angel shark consist of?
Answer: fish, crustaceans and various types of mollusks

Question: How many gills does the angel shark have?
Answer: five
Federer was born in Basel, Switzerland. His father, Robert Federer, is a Swiss-German from Berneck in the Canton of St. Gallen, and his mother, Lynette Federer (née Durand), is an Afrikaner from Kempton Park, Gauteng, in South Africa.

The island has fewer than 200 people, scattered around the coastline. The largest settlement is Port Howard on the east coast, which has an airstrip. Other settlements include Albemarle, Chartres, Dunnose Head, Fox Bay, Fox Bay West, Hill Cove, Port Stephens, and Roy Cove, most of which are linked by road and also have airstrips and harbours. In 1986, the population was 265, in 2001, it had fallen to 144.Because West Falkland is outside Stanley or RAF Mount Pleasant on East Falkland it is considered part of the "camp", a Falklander term for the area outside the main settlement.

Question: How many people live on the island?
Answer: fewer than 200
The lowland regions used to be covered by swaths of oak, beech, and hornbeam, which have since been cleared.There are two main entrances into Abkhazia. The southern entrance is at the Inguri bridge, a short distance from the city of Zugdidi. The northern entrance ("Psou") is in the town of Leselidze. Owing to the situation with a recognition controversy, many foreign governments advise their citizens against travelling to Abkhazia. According to President Raul Khajimba, over the summer of 2015, thousands of tourists visited Abkhazia.

Question: Which country do foreign governments warn their citizens against visiting?
Answer: Abkhazia

Sunbirds are a tropical Old World family, with representatives in Africa, Asia and Australasia. In Africa they are found mostly in sub-Saharan Africa and Madagascar but are also distributed in Egypt. In Asia the group occurs along the coasts of the Red Sea as far north as Israel, with a gap in their distribution till Iran, from where the group occurs continuously as far as southern China and Indonesia. In Australasia the family occurs in New Guinea, north eastern Australia and the Solomon Islands.  They are generally not found on oceanic islands, with the exception of the Seychelles. The greatest variety of species is found in Africa, where the group probably arose. Most species are sedentary or short-distance seasonal migrants. Sunbirds occur over the entire family's range, whereas the spiderhunters are restricted to Asia.The sunbirds and spiderhunters occupy a wide range of habitats, with a majority of species being found in primary rainforest, but other habitats used by the family including disturbed secondary forest, open woodland, open scrub and savannah, coastal scrub and alpine forest. Some species have readily adapted to human modified landscapes such as plantations, gardens and agricultural land. Many species are able to occupy a wide range of habitats from sea level to 4900 m.

Question: What country other than Africa can Sunbirds be located?
Answer: Egypt
The nests of sunbirds are generally purse-shaped, enclosed, suspended from thin branches with generous use of spiderweb. The nests of the spiderhunters are different, both from the sunbirds and in some cases from each other. Some, like the little spiderhunter, are small woven cups attached to the underside of large leaves; that of the yellow-eared spiderhunter is similarly attached but is a long tube. The nests of spiderhunters are inconspicuous, in contrast to those of the other sunbirds which are more visible. In most species the female alone constructs the nest. Up to four eggs are laid.  The female builds the nest and incubates the eggs alone, although the male assists in rearing the nestlings. In the spiderhunters both sexes help to incubate the eggs. The nests of sunbirds and spiderhunters are often targeted by brood parasites such as cuckoos and honeyguides.

Question: What color are the ears for one of the spiderhunters mentioned?
Answer: yellow
The sunbirds and spiderhunters make up a family, Nectariniidae, of passerine birds. They are small, slender passerines from the Old World, usually with downward-curved bills. Many are brightly coloured, often with iridescent feathers, particularly in the males. Many species also have especially long tail feathers. Their range extends through most of Africa to the Middle East, South Asia, South-east Asia and southern China, to Indonesia, New Guinea and northern Australia. Species diversity is highest in equatorial regions.

Question: What kind of birds are sunbirds and spiderhunters?
Answer: Nectariniidae

Question: What part of Australia are they living?
Answer: northern Australia
Because the Romans had to fight against the Franks, who plundered Cologne and Trier in 435, and because of other events Theodoric saw the chance to conquer Narbo Martius (in 436) to obtain access to the Mediterranean Sea and the roads to the Pyrenees. But Litorius, with the aid of the Huns, prevented the capture of the city and drove the Visigoths back to their capital Tolosa. Theodoric's offer of peace was refused, but the king won the decisive battle at Tolosa, and Litorius soon died in Gothic imprisonment from the injuries which he had received in this battle. Avitus went – according to the orders of Aëtius – to Tolosa and offered a peace treaty which Theodoric accepted. Perhaps the Romans recognized at that time the sovereignty of the Visigoth state.

Question: Access to which sea was Theodoric trying to gain by attacking Narbo Martius?
Answer: Mediterranean
Some recent scholars doubt that Theodoric issued legislation, as it was assumed in earlier times.

Question: What did the scholars doubt?
Answer: Theodoric issued legislation
The body of Theodoric wasn't found until the next day. According to Gothic tradition he was mourned and buried by his warriors on the battlefield. Immediately Thorismund was elected as successor of his father. Other sons of Theodoric were Theodoric II, Frederic, Euric I, Retimer and Himnerith.

Question: Who else was son to Theodoric?
Answer: Theodoric II, Frederic, Euric I, Retimer and Himnerith
Theodoric was also an enemy of the Suevic king Rechila in Iberia, because Visigoth troops assisted the imperial commander Vitus in his campaign against the Suevi in 446. But the ability of this people to conduct a strong defence and the better relations between Geiseric and the Roman Empire led Theodoric to change his foreign policy. He therefore, in February 449, married one of his daughters to the new Suevic king Rechiar, who visited his father-in-law at Tolosa in July 449. On his return – according to the author Isidore of Seville - Rechiar, with the assistance of Visigoth troops, devastated the area surrounding the city of Caesaraugusta and managed by guile to take Ilerda.

Question: Who did the people build a better defense and relationship with?
Answer: Geiseric and the Roman Empire
David Ben-Gurion was born in Płońsk in Congress Poland – then part of the Russian Empire. His father, Avigdor Grün, was a lawyer and a leader in the Hovevei Zion movement. His mother, Scheindel (Broitman), died when he was 11 years old. Ben-Gurion's birth certificate, when rediscovered in Poland in 2003, indicated that he had a twin brother who died shortly after birth. At the age of 14 he and two friends formed a youth club, Ezra, promoting Hebrew studies and emigration to the Holy Land.

Question: Who left David Ben Gurion's life when he was 11 years old?
Answer: His mother
On 14 May 1948, on the last day of the British Mandate, Ben-Gurion declared the independence of the state of Israel. In the Israeli declaration of independence, he stated that the new nation would "uphold the full social and political equality of all its citizens, without distinction of religion, race".

Question: What year did Ben-Gurion declare independence?
Answer: 1948
Discovering the tertiary structure of a protein, or the quaternary structure of its complexes, can provide important clues about how the protein performs its function and how it can be affected, i.e. in drug design. As proteins are too small to be seen under a light microscope, other methods have to be employed to determine their structure. Common experimental methods include X-ray crystallography and NMR spectroscopy, both of which can produce structural information at atomic resolution. However, NMR experiments are able to provide information from which a subset of distances between pairs of atoms can be estimated, and the final possible conformations for a protein are determined by solving a distance geometry problem. Dual polarisation interferometry is a quantitative analytical method for measuring the overall protein conformation and conformational changes due to interactions or other stimulus. Circular dichroism is another laboratory technique for determining internal β-sheet / α-helical composition of proteins. Cryoelectron microscopy is used to produce lower-resolution structural information about very large protein complexes, including assembled viruses; a variant known as electron crystallography can also produce high-resolution information in some cases, especially for two-dimensional crystals of membrane proteins. Solved structures are usually deposited in the Protein Data Bank (PDB), a freely available resource from which structural data about thousands of proteins can be obtained in the form of Cartesian coordinates for each atom in the protein.Many more gene sequences are known than protein structures. Further, the set of solved structures is biased toward proteins that can be easily subjected to the conditions required in X-ray crystallography, one of the major structure determination methods. In particular, globular proteins are comparatively easy to crystallize in preparation for X-ray crystallography. Membrane proteins and large protein complexes, by contrast, are difficult to crystallize and are underrepresented in the PDB. Structural genomics initiatives have attempted to remedy these deficiencies by systematically solving representative structures of major fold classes. Protein structure prediction methods attempt to provide a means of generating a plausible structure for proteins whose structures have not been experimentally determined.

Question: What is the variant called tat produces high resolution information in Cryoelectron microscopy?
Answer: electron crystallography
Most proteins consist of linear polymers built from series of up to 20 different L-α- amino acids. All proteinogenic amino acids possess common structural features, including an α-carbon to which an amino group, a carboxyl group, and a variable side chain are bonded. Only proline differs from this basic structure as it contains an unusual ring to the N-end amine group, which forces the CO–NH amide moiety into a fixed conformation. The side chains of the standard amino acids, detailed in the list of standard amino acids, have a great variety of chemical structures and properties; it is the combined effect of all of the amino acid side chains in a protein that ultimately determines its three-dimensional structure and its chemical reactivity.

Question: How many different amino acids make up a protein?
Answer: 20
Proteins are assembled from amino acids using information encoded in genes. Each protein has its own unique amino acid sequence that is specified by the nucleotide sequence of the gene encoding this protein. The genetic code is a set of three-nucleotide sets called codons and each three-nucleotide combination designates an amino acid, for example AUG (adenine-uracil-guanine) is the code for methionine. Because DNA contains four nucleotides, the total number of possible codons is 64; hence, there is some redundancy in the genetic code, with some amino acids specified by more than one codon. Genes encoded in DNA are first transcribed into pre-messenger RNA (mRNA) by proteins such as RNA polymerase. Most organisms then process the pre-mRNA (also known as a primary transcript) using various forms of Post-transcriptional modification to form the mature mRNA, which is then used as a template for protein synthesis by the ribosome. In prokaryotes the mRNA may either be used as soon as it is produced, or be bound by a ribosome after having moved away from the nucleoid. In contrast, eukaryotes make mRNA in the cell nucleus and then translocate it across the nuclear membrane into the cytoplasm, where protein synthesis then takes place. The rate of protein synthesis is higher in prokaryotes than eukaryotes and can reach up to 20 amino acids per second.The process of synthesizing a protein from an mRNA template is known as translation. The mRNA is loaded onto the ribosome and is read three nucleotides at a time by matching each codon to its base pairing anticodon located on a transfer RNA molecule, which carries the amino acid corresponding to the codon it recognizes. The enzyme aminoacyl tRNA synthetase "charges" the tRNA molecules with the correct amino acids. The growing polypeptide is often termed the nascent chain. Proteins are always biosynthesized from N-terminus to C-terminus.The size of a synthesized protein can be measured by the number of amino acids it contains and by its total molecular mass, which is normally reported in units of daltons (synonymous with atomic mass units), or the derivative unit kilodalton (kDa). The average size of a protein increases from Archaea to Bacteria to Eukaryote (283, 311, 438 residues and 31, 34, 49 kDa respecitvely) due to a bigger number of protein domains constituting proteins in higher organisms. For instance, yeast proteins are on average 466 amino acids long and 53 kDa in mass. The largest known proteins are the titins, a component of the muscle sarcomere, with a molecular mass of almost 3,000 kDa and a total length of almost 27,000 amino acids.

Question: What does AUG stand for?
Answer: adenine-uracil-guanine

Question: How many nucleotides does DNA contain?
Answer: four

Question: What is the average mass of yeast proteins?
Answer: 53 kDa
Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific three-dimensional structure that determines its activity.

Question: What is another name for large biomolecules?
Answer: macromolecules
Proteins can be informally divided into three main classes, which correlate with typical tertiary structures: globular proteins, fibrous proteins, and membrane proteins. Almost all globular proteins are soluble and many are enzymes. Fibrous proteins are often structural, such as collagen, the major component of connective tissue, or keratin, the protein component of hair and nails. Membrane proteins often serve as receptors or provide channels for polar or charged molecules to pass through the cell membrane.A special case of intramolecular hydrogen bonds within proteins, poorly shielded from water attack and hence promoting their own dehydration, are called dehydrons.

Question: What type of protein is usually always soluble?
Answer: globular
Proteins were first described by the Dutch chemist Gerardus Johannes Mulder and named by the Swedish chemist Jöns Jacob Berzelius in 1838. Mulder carried out elemental analysis of common proteins and found that nearly all proteins had the same empirical formula, C400H620N100O120P1S1. He came to the erroneous conclusion that they might be composed of a single type of (very large) molecule. The term "protein" to describe these molecules was proposed by Mulder's associate Berzelius; protein is derived from the Greek word πρώτειος (proteios), meaning "primary", "in the lead", or "standing in front", + -in. Mulder went on to identify the products of protein degradation such as the amino acid leucine for which he found a (nearly correct) molecular weight of 131 Da. Prior to "protein", other names were used, like "albumins" or "albuminous materials" (Eiweisskörper, in German).Early nutritional scientists such as the German Carl von Voit believed that protein was the most important nutrient for maintaining the structure of the body, because it was generally believed that "flesh makes flesh." Karl Heinrich Ritthausen extended known protein forms with the identification of glutamic acid. At the Connecticut Agricultural Experiment Station a detailed review of the vegetable proteins was compiled by Thomas Burr Osborne. Working with Lafayette Mendel and applying Liebig's law of the minimum in feeding laboratory rats, the nutritionally essential amino acids were established. The work was continued and communicated by William Cumming Rose. The understanding of proteins as polypeptides came through the work of Franz Hofmeister and Hermann Emil Fischer in 1902. The central role of proteins as enzymes in living organisms was not fully appreciated until 1926, when James B. Sumner showed that the enzyme urease was in fact a protein.The difficulty in purifying proteins in large quantities made them very difficult for early protein biochemists to study. Hence, early studies focused on proteins that could be purified in large quantities, e.g., those of blood, egg white, various toxins, and digestive/metabolic enzymes obtained from slaughterhouses. In the 1950s, the Armour Hot Dog Co. purified 1 kg of pure bovine pancreatic ribonuclease A and made it freely available to scientists; this gesture helped ribonuclease A become a major target for biochemical study for the following decades.

Question: Which assiciate of Mulders came up with the word protein?
Answer: Berzelius

Question: Who named proteins?
Answer: Jöns Jacob Berzelius
Short proteins can also be synthesized chemically by a family of methods known as peptide synthesis, which rely on organic synthesis techniques such as chemical ligation to produce peptides in high yield. Chemical synthesis allows for the introduction of non-natural amino acids into polypeptide chains, such as attachment of fluorescent probes to amino acid side chains. These methods are useful in laboratory biochemistry and cell biology, though generally not for commercial applications. Chemical synthesis is inefficient for polypeptides longer than about 300 amino acids, and the synthesized proteins may not readily assume their native tertiary structure. Most chemical synthesis methods proceed from C-terminus to N-terminus, opposite the biological reaction.

Question: How many amino acids does it take for Chemical Synthesis to become inefficient?
Answer: 300
Tertiary structure: the overall shape of a single protein molecule; the spatial relationship of the secondary structures to one another. Tertiary structure is generally stabilized by nonlocal interactions, most commonly the formation of a hydrophobic core, but also through salt bridges, hydrogen bonds, disulfide bonds, and even posttranslational modifications. The term "tertiary structure" is often used as synonymous with the term fold. The tertiary structure is what controls the basic function of the protein.

Question: Protiens have a hydrophobic core, but have other mehtods to control the basic protein function called what?
Answer: tertiary structure
