Answer:
Cotton and Tobacco
Explanation:
It was the most poular prouducts back in that time
Answer:
hypothesis
Explanation:
Hypothesis: The term hypothesis is defined as an explanation or idea that an experimenter test via experimentation or study. A hypothesis is denoted as something less than a well-established theory and more than a random guess. It helps a researcher to better understand the area of study and gives a specific direction to a particular study.
Types: Simple hypothesis, null hypothesis, complex hypothesis, and logical hypothesis.
In the question above, Dr. Birk's prediction regarding students' self-perceptions is an example of a hypothesis.
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.
The statement shows that men and women are alike in many ways yet so different. Or if you want to be funny you could say Men are tails and women are heads because just like in the real world head is something men will never get :))
