Answer:
In order to express the results as a percent, divide the nutrient content (which is expressed in ppm) by 10,000. For example, if the reported value for P2O5 is 2,690 ppm, the calculation to convert to percent would be: 2,690 ppm ÷ 10,000 = 0.269%.
The answer is a shift from human and animal energy to energy from other sources.
Answer:
The three predominant universalizing religions between the first and twelfth centuries CE were Christianity, Buddhism, and Islam.
Universal religions are religions that attempt to gain conversions from anyone, regardless of race, ethnicity, or geographic area.
Answer:
Importance of Greenhouse Gases
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat trapping causes changes in the radiative balance of the Earth—the balance between energy received from the sun and emitted from Earth—that alter climate and weather patterns at global and regional scales.
Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years.1 Natural factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.
