Answer:
The Tigris and Euphrates rivers made it possible to grow wheat on the arid Mesopotamian plains, but the dry climate eventually defeated human engineering. Irrigation brought water to fields faster than it could drain out. As salt-rich groundwater rose and surface water evaporated, mineral salts built up in the soils. Farmers switched to more salt-tolerant grains like barley, but the harder they farmed, the less they harvested. After about 2,000 years, the once-fertile land of southern Mesopotamia was barren.

Answer: Option (D)
Explanation:
Here, in this particular case we can state that Andrew's response signifies <em>role confusion</em>. Under role confusion there tends to be the failure to authorizes a ability of identify oneself within an organization or society. The role confusion mostly includes individuals that are not certain about oneself or the part they play in the society.
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:
Hello, I would say the correct answer is C Medium if I got it wrong just tell me.
Moral reasoning is the subdivision of psychology which involves the fundamental philosophy of moralities and integrities. Youngsters show moral reasoning skills at early adolescent age.
It’s a process by which a person can discriminate what is right and what is wrong. It can occur within one’s own self or between the individuals. It promotes healthy relationship when adhered to.
According to Higgins students from urban high school showcased a high moral reasoning as they were exposed to education from a very little age and they know to distinguish between what is good and what is not good.
