Because they are a country founded on capitalism and the pursuit of prosperity through a free market system. Communism pushes the opposite ideals and back in the day Russia was a military large superpowers that followed a communist system that the US felt threatened by.
Answer:
A) Formulate question,conduct research,propose hypothesis,test hypothesis
Explanation:
The scientific method is pertinent to the success of a scientific experiment. The scientific method is a sequential steps of processes involved in an experimentation. The correct order of steps that determines the process when following the scientific method are:
1) Formulate question: Asking a question about what has been previously observed is the key to starting a scientific method.
2) Conduct research: Research is done based on a previous observation that has been made by in order to gather necessary information.
3) Propose hypothesis: A hypothesis is a predictive statement or explanation to an asked question about the experiment that can be tested. It usually goes in an IF, THEN format.
4) Test hypothesis: As stated in the previous step, a hypothesis must be testable, which is done by conducting an experiment. The outcome of the experiment proves or disproves the hypothesis.

Answer:
The correct answer will be option-D.
Explanation:
Photosynthesis proceeds in two stages: light-dependent and light-independent reaction.
The light-dependent begins when the chlorophyll pigment of the photosystem absorbs light energy. This absorption causes the excitation of the electrons provided by the chlorophyll molecule.
The excited electrons accepted by electron acceptor molecule from reaction center and a chain of electron flow begin called electron transport chain.
This transport of electrons creates a scarcity of electron in photosystem which causes splitting of the water molecule as a result of which oxygen gas is released.
Thus, option-D is the correct answer.
Answer:
Water provides hydrogen and electrons used in producing glucose.
Explanation:
Photosynthesis is process peculiar to green plants and other organisms like algae and some bacteria. Plants synthesize their own food in form of an organic molecule (glucose) by combining carbondioxide (CO2) and H2O in the presence of sunlight. They absorb light energy from the sun to power the first process called LIGHT stage, where NADPH and ATP are produced to be used in the next stage. The electrons used to reduce NADP to NADPH comes from the "PHOTOLYSIS OF WATER"
CO2 is absorbed via the stomata in the leaves of plants. The CO2 is then fixed in the stroma of the CHLOROPLAST when it undergoes series of reactions in the Calvin cycle to produce glucose. However, the glucose molecule (C6H12O6) contains hydrogen which CO2 does not possess, this Hydrogen is provided by water during the light stage where it donated it to NADP+
