Because the Germans were Taking on a attitude of imperialism and they were sinking American ships
Grain storage gave people security and the ability of planning ahead. It means that they could store what they produced for the winter and not fear the winter. They could make long term plans and not just live day by day, fearing whether they would have enought to eat the following day
Additionally, it allowed for distribution of grain according to the wishes of those in power
I think the most reasonable answer would be the second option, B. “Critical value”
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:
higher
Explanation:
because during that same year the individual maybe still getting used to marriage and paying accumulated debt ,on the other hand they still trying to get used to the working environment with demanding hours.they also have to think about the baby.the stress levels become higher because all of the challenges are new facing one person at the same time.
