Ques:Information:  - Cassius Dio or Dio Cassius was a Roman statesman and historian of Greek origin. He published 80 volumes of history on Ancient Rome, beginning with the arrival of Aeneas in Italy. The volumes documented the subsequent founding of Rome (753 BC), the formation of the Republic (509 BC), and the creation of the Empire (31 BC), up until 229 AD. Written in Ancient Greek over 22 years, Dio's work covers approximately 1,000 years of history. Many of his 80 books have survived intact, or as fragments, providing modern scholars with a detailed perspective on Roman history.  - Aelius Herodianus ( Greek :   ) or Herodian ( fl . 2nd century CE ) was one of the most celebrated grammarians of Greco - Roman antiquity . He is usually known as Herodian except when there is a danger of confusion with the historian also named Herodian . He was the son of Apollonius Dyscolus and was born in Alexandria . From there he seems to have moved to Rome , where he gained the favour of the emperor Marcus Aurelius , to whom he dedicated a work on prosody .  - Elagabalus , also known as Heliogabalus (203  March 11, 222), was Roman emperor from 218 to 222. A member of the Severan dynasty, he was Syrian, the second son of Julia Soaemias and Sextus Varius Marcellus. In his early youth he served as a priest of the god Elagabal in the hometown of his mother's family, Emesa. As a private citizen, he was probably named Sextus Varius Avitus Bassianus. Upon becoming emperor he took the name Marcus Aurelius Antoninus Augustus. He was called Elagabalus only after his death.  - Herodian or Herodianus of Syria, sometimes referred to as "Herodian of Antioch" (c. 170  c. 240), was a minor Roman civil servant who wrote a colourful history in Greek titled "History of the Empire from the Death of Marcus" (    ) in eight books covering the years 180 to 238. His work is not entirely reliable although his relatively unbiased account of Elagabalus is more useful than that of Cassius Dio. He was a Greek (perhaps from Antioch) who appears to have lived for a considerable period of time in Rome, but possibly without holding any public office. From his extant work, we gather that he was still living at an advanced age during the reign of Gordianus III, who ascended the throne in 238. Beyond this, nothing is known of his life.    After reading the paragraphs above, we are interested in knowing the entity with which 'aelius herodianus' exhibits the relationship of 'date of birth'. Find the answer from the choices below.  Choices: - 11  - 170  - 180  - 203  - 218  - 22  - 240  - 31  - 80

Ans:180

Ques:Information:  - Proteins (or ) 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, 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.  - In chemistry isomerization (also isomerisation) is the process by which one molecule is transformed into another molecule which has exactly the same atoms, but the atoms have a different arrangement e.g. A-B-C  B-A-C (these related molecules are known as isomers ). In some molecules and under some conditions, isomerization occurs spontaneously. Many isomers are equal or roughly equal in bond energy, and so exist in roughly equal amounts, provided that they can interconvert somewhat freely; that is, the energy barrier between the two isomers is not too high. When the isomerization occurs intramolecularly it is considered a rearrangement reaction.  - In computer science, ACID ("Atomicity, Consistency, Isolation, Durability") is a set of properties of database transactions. In the context of databases, a single logical operation on the data is called a transaction. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction.  - Aconitase (aconitate hydratase) is an enzyme that catalyses the stereo-specific isomerization of citrate to isocitrate via "cis"-aconitate in the tricarboxylic acid cycle, a non-redox-active process.  - 3 - Isopropylmalate dehydratase ( E.C.4.2.1.33 ) is an aconitase homologue , which catalyses the isomerisation of 2 - isopropylmalate to 3 - isopropylmalate , via dehydration , in the biosynthesis of leucine .  - Leucine (abbreviated as Leu or L; encoded by the six codons UUA, UUG, CUU, CUC, CUA, and CUG) is an -amino acid used in the biosynthesis of proteins. It contains an -amino group (which is in the protonated NH form under biological conditions), an -carboxylic acid group (which is in the deprotonated COO form under biological conditions), and an isobutyl side chain, classifying it as a nonpolar (at physiological pH) amino acid. It is essential in humansmeaning the body cannot synthesize it and thus must obtain from the diet.  - Redox (short for reductionoxidation reaction) is a chemical reaction in which the oxidation states of atoms are changed. Any such reaction involves both a reduction process and a complementary oxidation process, two key concepts involved with electron transfer processes. Redox reactions include all chemical reactions in which atoms have their oxidation state changed; in general, redox reactions involve the transfer of electrons between chemical species. The chemical species from which the electron is stripped is said to have been oxidized, while the chemical species to which the electron is added is said to have been reduced. It can be explained in simple terms:    After reading the paragraphs above, we are interested in knowing the entity with which '3-isopropylmalate dehydratase' exhibits the relationship of 'instance of'. Find the answer from the choices below.  Choices: - amino acid  - bond  - carboxylic acid  - chain  - chemical reaction  - computer  - data  - database  - dna  - enzyme  - humans  - key  - location  - process  - rearrangement reaction  - science  - sequence  - set  - side  - six  - state  - structure  - three  - two
