Римское право - это правовая система Древнего Рима, включая правовые разработки, охватывающие более тысячи лет юриспруденции, от Двенадцати таблиц (около 449 г. до н.э.) до Corpus Juris Civilis (529 г. н.э.), предписанного императором Восточной Римской империи Юстинианом I. Римское право составляет основу гражданского права, наиболее широко используемой сегодня правовой системы, и эти термины иногда используются как синонимы. Историческое значение римского права отражено в продолжающемся использовании латинской юридической терминологии во многих правовых системах, на которые она влияет, включая общее право.
После распада Западной Римской империи римское право оставалось в силе в Восточной Римской империи. Начиная с VII века юридическим языком на Востоке был греческий.
At a fundamental level, water provides electrons to replace those removed from chlorophyll in photosystem II. Also, water produces oxygen as well as reduces NADP to NADPH (required in the Calvin cycle) by liberating H+ ions
During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen. The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas (O2).
Water also has another important role of being an electron feeder. In the process of photosynthesis, water provides the electron that binds the hydrogen atom (of a water molecule) to the carbon (of carbon dioxide) to give sugar (glucose).
Water acts as a reducing agent by providing H+ ions that convert NADP to NADPH. Since NADPH is an important reducing agent present in chloroplasts, its production results in a deficit of electrons, resulting from oxidation of chlorophyll. This loss of electron must be fulfilled by electrons from some other reducing agent. Photosystem II involves the first few steps of the Z-scheme (the diagram of the electron transport chain in photosynthesis) and therefore a reducing agent that can donate electrons is required to oxidize chlorophyll, which is provided by water (acting as a source of electrons in green plants and cynobacteria). Hydrogen ions thus released create a chemical potential (chemiosmotic) across the membrane that finally results in synthesis of ATP. Photosystem II is the primary known enzyme that acts as catalyst in this oxidation of water.
Silk Road:
The Silk Road specifically refers to the trading land routes that connects East and Southeast Asia to South Asia and Persia followed by Arabian Peninsula, East Africa and finally Southern Europe.
This network was regularly used from 130 BCE and part of that road is still in existence as a paved highway that connects Pakistan and the Uygur.
Chinese are the one who first started trading in this road and as its name indicates it is mainly used as a trade route for trading silks.
Hence this ancient road played a major role on times when it was constructed.
