if it quacks like duck soup Troy troia
The Troad (/ˈtroʊˌæd/ or /ˈtroʊəd/; Greek: Τρωάδα, Troáda) or Troas (/ˈtroʊəs/; Ancient Greek: Τρῳάς, Trōiás or Τρωϊάς, Trōïás) is a historical region in northwestern Anatolia. It corresponds with the Biga Peninsula (Turkish: Biga Yarımadası) in the Çanakkale province of modern Turkey. Bounded by the Dardanelles to the northwest, by the Aegean Sea to the west and separated from the rest of Anatolia by the massif that forms Mount Ida, the Troad is drained by two main rivers, the Scamander (Karamenderes) and the Simois, which join at the area containing the ruins of Troy...Hedylogos
The Simoeis was a small river of the ancient Troad, having its source in Mount Ida, or more accurately in Mount Cotylus, which passed by Troy, joined the Scamander River below that city. This river is frequently spoken of in the Iliad, and described as a rapid mountain torrent. The river is also noted by the ancient geographers Strabo, Ptolemy, Stephanus of Byzantium, Pomponius Mela, and Pliny the Elder. Its present course is so altered that it is no longer a tributary of the Scamander, but flows directly into the Hellespont.
Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language.
The letter eta (Η,
, originally called hēta) had two different functions, both derived from the name of its Phoenician model, hēth: the majority of Greek dialects continued to use it for the consonant /h/, similar to its Phoenician value ([ħ]). However, the consonant /h/ was progressively lost from the spoken language (a process known as psilosis), and in those dialects where this had already happened early on in the archaic period, Η was instead used to denote the long vowel /ɛː/, which occurred next in its name and was thus, in the /h/-less dialects, its natural acrophonic value. Early psilotic dialects include eastern Ionic Greek, the Aeolic Greek of Lesbos, as well as the Doric Greek of Crete and Elis.
The distribution of vocalic Η and Ε differs further between dialects, because the Greek language had a system of three distinct e-like phonemes: the long open-mid /ɛː/ (classical spelling η), the long close-mid /eː/ (later merged with the diphthong /ei/, classical spelling ει), and the short vowel /e/ (classical spelling ε). In the psilotic dialects of Anatolia and adjacent eastern Aegean islands, as well as Crete, vocalic Η was used only for /ɛː/. In a number of Aegean islands, notably Rhodes, Milos, Santorini and Paros, it was used both for /h/ and for /ɛː/ without distinction. In Knidos, a variant letter was invented to distinguish the two functions: Η was used for /h/, and
for /ɛː/. In south Italian colonies, especially Taranto, after c. 400 BC, a similar distinction was made between Η for /ɛː/, and
for /h/. This latter symbol was later turned into the diacritic sign for rough breathing by the Alexandrine grammarians...In Naxos the system was slightly different: here, too, the same letter was used for /h/ and for a long vowel, but only in those cases where a long e-like sound had arisen through raising from older /aː/, not – as other users of vocalic eta did – also for the older /ɛː/ inherited from proto-Greek. This probably means that while in the dialects of other eta users the old and new long e had already merged in a single phoneme, the raising sound in Naxos was still distinct both from /aː/ and /ɛː/, hence probably an [æ]-like sound...
Region of repetitive nucleotide sequences on chromosomes
For the use of "telomere" in insect morphology, see Telomere (insect morphology). For other uses, see Telomere (disambiguation).
A telomere (/ˈtɛləmɪər/ or /ˈtiːləmɪər/, from Ancient Greek: τέλος, romanized: télos, lit. 'end' and Ancient Greek: μέρος, romanized: méros, lit. 'part') is a region of repetitive nucleotide sequences associated with specialized proteins at the ends of linear chromosomes. Although there are different architectures, telomeres, in a broad sense, are a widespread genetic feature most commonly found in eukaryotes. In most, if not all species possessing them, they protect the terminal regions of chromosomal DNA from progressive degradation and ensure the integrity of linear chromosomes by preventing DNA repair systems from mistaking the very ends of the DNA strand for a double strand break.
EukaryoteDomain of life having cells with nuclei

Eukaryotes (/juːˈkærioʊts, -əts/) are organisms whose cells have a nucleus enclosed within a nuclear envelope. They belong to the group of organisms Eukaryota or Eukarya; their name comes from the Greek εὖ (eu, "well" or "good") and κάρυον (karyon, "nut" or "kernel"). The domain Eukaryota makes up one of the three domains of life; bacteria and archaea (both prokaryotes) make up the other two domains. The eukaryotes are usually now regarded as having emerged in the Archaea or as a sister of the Asgard archaea. This implies that there are only two domains of life, Bacteria and Archaea, with eukaryotes incorporated among archaea. Eukaryotes represent a small minority of the number of organisms; however, due to their generally much larger size, their collective global biomass is estimated to be about equal to that of prokaryotes. Eukaryotes emerged approximately 2.1–1.7 billion years ago, during the Proterozoic eon, likely as flagellated phagotrophs. What sounds like spectrum looks like spectrum is spectrum is not named spectrum...Archaea and bacteria are generally similar in size and shape, although a few archaea have very different shapes, such as the flat, square cells of Haloquadratum walsbyi. Despite this morphological similarity to bacteria, archaea possess genes and several metabolic pathways that are more closely related to those of eukaryotes, notably for the enzymes involved in transcription and translation. Other aspects of archaeal biochemistry are unique, such as their reliance on ether lipids in their cell membranes, including archaeols. Archaea use more diverse energy sources than eukaryotes, ranging from organic compounds such as sugars, to ammonia, metal ions or even hydrogen gas. The salt-tolerant Haloarchaea use sunlight as an energy source, and other species of archaea fix carbon, but unlike plants and cyanobacteria, no known species of archaea does both. Archaea reproduce asexually by binary fission, fragmentation, or budding; unlike bacteria, no known species of Archaea form endospores. The first observed archaea were extremophiles, living in extreme environments such as hot springs and salt lakes with no other organisms. Improved molecular detection tools led to the discovery of archaea in almost every habitat, including soil, oceans, and marshlands. Archaea are particularly numerous in the oceans, and the archaea in plankton may be one of the most abundant groups of organisms on the planet...
Digamma (Ϝ) for the sound /w/ was generally used only in those local scripts where the sound was still in use in the spoken dialect. During the archaic period, this includes most of mainland Greece (except Attica), as well as Euboea and Crete. In Athens and in Naxos it was apparently used only in the register of poetry. Elsewhere, i.e. in most of the Aegean islands and the East, the sound /w/ was already absent from the language.
The shape of the letter varies locally and over time. The most common early form is . Over time it developed in analogy with Epsilon (which changed from to "E"), becoming either the classical "F" or . Early Crete had an archaic form (which resembled its original model, the Y-shaped Phoenician waw ), or a variant with the stem bent sideways ().
The van 't Hoff factor i (named after Dutch chemist Jacobus Henricus van 't Hoff) is a measure of the effect of a solute on colligative properties such as osmotic pressure, relative lowering in vapor pressure, boiling-point elevation and freezing-point depression. The van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non-electrolytes dissolved in water, the van 't Hoff factor is essentially 1. For most ionic compounds dissolved in water, the van 't Hoff factor is equal to the number of discrete ions in a formula unit of the substance. This is true for ideal solutions only, as occasionally ion pairing occurs in solution. At a given instant a small percentage of the ions are paired and count as a single particle. Ion pairing occurs to some extent in all electrolyte solutions. This causes the measured van 't Hoff factor to be less than that predicted in an ideal solution. The deviation for the van 't Hoff factor tends to be greatest where the ions have multiple charges.
Dissociated solutes
The degree of dissociation is the fraction of the original solute molecules that have dissociated. It is usually indicated by the Greek symbol {\displaystyle \alpha }\alpha . There is a simple relationship between this parameter and the van 't Hoff factor. If a fraction {\displaystyle \alpha }\alpha of the solute dissociates into {\displaystyle n}n ions, then
{\displaystyle i=1+\alpha (n-1).}{\displaystyle i=1+\alpha (n-1).}
For example, the dissociation:-:KCl ⇌ K+ + Cl− yields {\displaystyle n=2}n=2 ions, so that {\displaystyle i=1+\alpha }{\displaystyle i=1+\alpha }.
