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.
Answer:
The further people are from the earthquake source, the more warning time they will have, as the waves will take longer to reach them
Explanation:
Fatal accidents during an earthquake can happen in the matter of seconds. Sometimes, rooftops can fall on top of the victims' head. An explosion could occur from leaked gas, etc.
Even if earthquakes can't be predicted, having that additional seconds from the warning can be all it takes for a person to get out from their house and go to some place safe.
Answer:
Islam includes the Jurisprudence of belief, such as faith in Allah and faith in the Last Day and Judgement. B. It includes the Jurisprudence of morality, such as honesty and forbidden lie.
- The Profession of Faith—The Shahada. The Profession of Faith, the shahada, is the most fundamental expression of Islamic beliefs. It simply states that “There is no God but God and Muhammad is his prophet.” It underscores the monotheistic nature of Islam.

All of these acts increased taxation on the colonies, and did so without the permission or discussion from the collonies, so were one-sides.
Stamp Act said that the paper used in the colonies for media would have to be produced in London, the Tea Act validated local taxes on tea and the Sugar act imposed a high act on imported sugar.
A strong dollar makes imports less expensive and foreign travel cheaper. A weak dollar makes imports more expensive and foreign travel more expensive.
