The victory of the United States against Great Britain in the Revolutionary war was‚ and continues to be one of the biggest upsets militarily. The Superior British army seemed to have every advantage‚ however the United States experienced key political‚ diplomatic‚ and military advantages that led to the success of the Revolution. Politically the colonies had gone through many key changes in ideology that gave the idea of revolution the traction that it would need to gain public support. The people

Then you get it when you eat the plants or if you also eat animals you Nitrogen from the meat also. These bacteria in the root nodules have an enzyme called ___nitrogenase____ that helps them split the Nitrogen molecules into other forms. 6. The process the microbes go through to break the mainly toxic ammonia molecule into __nitrite__ (NO2- ) and ___nitrate__ (NO3-) is called ___nitrification__. 7. When these smaller molecules are taken up into plant tissue the term is __Assimilation__

1. Living organisms play an important role in the recycling of many elements within an ecosystem. One such way this idea can be proven is through the study of carbon in an ecosystem. Plants‚ for starters‚ are a major part of this carbon cycle. During photosynthesis‚ plants remove carbon dioxide from the atmosphere and release oxygen as a waste product. Another major contributor to this vital cycle is the human being. The average human being goes through respiration each day to help maintain

AP Biology notes: Chapter 2- The Chemical Context of Life 1. Overview * The bombardier beetle fights the ants that plague it by using chemistry. * The natural systems and environment that organisms live in involves chemistry and physics. * Biology is not the only category of science. There is also chemistry‚ physics‚ and engineering. * Organization of life is separated into a hierarchy of structural levels. 2. Elements and Compounds * Matter- anything that takes up
