regarding price and quantity discussed in the paragraph starting “Dazzled by…” in 2011 and 2012 (so far) using a different diagram for each year. Also explain why‚ using economic analysis‚ the article links cotton‚ food‚ and fuel. During 2011 many farmers swapped their food crops for cotton crops. This could be shown using a PPF (Production Possibily Frontier) diagram. A PPF diagram illustrates what an economy can produce using the given resources (in this case cotton crops and food crops).

Choose one of the following models of psychosynthesis: (a) subpersonalities‚ (b) ‘I’ and the sense of identity‚ (c) the egg diagram. Discuss and critique its usefulness as a tool for understanding your own development and its possible application to clinical work. This essay will choose to discuss model (b) ‘I’ and the sense of identity‚ particularly in relation to the work of John Firman. This essay aligns with the definitions of “I” and Self as outlined by Assagioli (1965)‚ that “I” is one’s

Question: Explain how human activities can interrupt or modify the nutrient cycles in the coniferous forest. Refer in detail to examples you have studied. Attempt to show as annotated diagrams the altered minerals nutrient cycle. Essay: The coniferous forest occurs in cold climates to the poleward side of 60 N in Eurasia and North America as well as high attitudes in more temperate latitudes and in Southern Chile. It has an average NPP of 800g/m/yr. There is usually only one layer of vegetation

The traditional TOK diagram indicates four ways of knowing. Propose the inclusion of a fifth way of knowing selected from intuition‚ memory or imagination‚ and explore the knowledge issues it may raise in two areas of knowledge. Our whole life is a continuous process of gaining information. This information is our basic knowledge about the world. It is coming in different forms‚ from different sources. And it is vitally important to store this information‚ in order to understand your own present

axes. An electron in the d X2 - y2 and dz2 orbitals is therefore most effected by the field of the ligands and is raised in energy relative to an electron in the dxy‚ dyz and dzx orbitals. The combined energy level diagram is therefore composed of two upper orbitals‚ of equal energy‚ and three lower orbitals‚ which are also degenerate (Figure 4.1). The energy zero is conveniently taken as the weighted mean of the en ergies of these two sets of orbitals; the lower trio are thus stabilized by -2/5
