The transition metal group of the periodic table exhibits a wide array of different colored compounds. The complex ion tetraamminecopper(II) contains four ammonia molecules covalently bonded to a copper(II) ion. In aqueous solutions, Cu2+ ions will bond to four water molecules in a square planar geometry. The solution is a light blue color. The water molecules can be displaced by ammonia molecules, which form more stable complex bases than water.

Solution Formula: Transmittence= 10^(-Absorbance) T=10^(-A) T=10^-1.5 T=0.031623 %T=3.1623% This means that 96.8377% light has been absorbed and only 3.1623% has been transmitted. Detection of such low value of transmitted by the detector will increase the chances of error. Also, because transmittence decreases logarithmically, linearity is lost at high concentration of sample. .

You do not have to write them all out. ow many tetra peptides can be formed by combining alanine, serine, glycine and How does glyphosate inhibit weed growth, explain in simple terms involving essential amino acids and simple enzyme catalysis? 23. 24. What is the cause of cyele cell anemia? 25. Zidovudne (aka AZT) was the first drug approved to treat HIV. How does it work the molecular level? ?? 9 Solution Answer 24.) Sickle cell anemia is an inherited form of anemia in which there aren\'t enough healthy red blood cells to carry adequate oxygen throughout your body. Sickle cell anemia is caused by a mutation in the gene that tells the body to make the red, iron-rich compound that gives blood its red color (hemoglobin). Hemoglobin allows red blood cells to carry oxygen from your lungs to all parts of your body. In sickle cell anemia, the abnormal hemoglobin causes red blood cells to become rigid, sticky and misshapen. After the hemoglobin molecules give up their oxygen, some of them may cluster together and form long, rod-like structures that become stiff and assume a sickle shape. The sickle cell gene is passed from generation to generation in a pattern of inheritance called autosomal recessive inheritance. Two genes for the sickle hemoglobin must be inherited from one\'s parents in order to have the disease. A person who receives a gene for sickle cell disease from one parent and a normal gene from the other has a condition called \"sickle cell trait.\" Sickle cell trait produces no symptoms or problems for most people. Sickle cell disease can neither be contracted nor passed on to another person. .

Answer the below in your own words: What were the reasons for the decolonization movement after WWII? Solution The Second World war greatly weakened European colonial rule, forcing the allies to abandon many of their colonial possessions in the face of invasion. When the European powers tried to return to rule again they found that the local nationalists had encouraged the population to reject European rule in favor of self-determination. A good example of this was Indonesia where the Dutch had ruled for over 150 years. In 1948, Indonesia declared Independence, and Netherlands found themselves without any support. Another reason was that when the war ended, one of the themes of the United Nations was encouraging self-determination and ending colonial rule, which was one of the main causes of the First World War. But i think that the most important factor is that the world, particularly the United States, refused to help or support European powers re-establish colonial rule. One of the reasons for this was that the U.S saw European colonial rule as deterimental towards its own global economic aspirations. A good example of this was the U.S attitude towards Britain, which had used the Imperial system to exclude the U.S from favourable trade with Australia, Canada, and New Zealand. The U.S was also reluctant to use money and manpower to fight guerilla wars to support European rule. The U.S was more than aware that the world would also reject any war fought to uphold colonial rule. When the nationalists in Vietnam tried to overthrow French rule, the French had no allies and lacked general support. Another reason was that with the spread of communism in Europe and SE Asia, the U.S was more than aware that European colonial rule provided fertile ground for anti-European sentiment, which invited communist sympathies. .

Answer in your own words: Would you agree with Karl Marx in saying that the Industrial Revolution and its capitalistic foundations negatively affected the working classes? Solution The Industrial Revolution advance capitalism to its final stage, which Marx saw as an ultimate evil. Before the industrial revolution feudalism existed which is a society run by land owners when the aristocracy gives land to the peasants and those landowners scrape and consume the profit the peasants make by taxation and taking of food using the knights as the collectors. Financial capitalism was a growing idea taken from the Greeks and Romans who believed that most individuals had a right to sell things to gain profit and to run businesses. This idea was reintroduced to Europe during the Renaissance, but it was still applied using feudal methods. The American and French revolution helped strengthen capitalism and the end of the great French war made England one of the richest nations in the world. Advances in technology and new inventions brought about the Industrial Revolution. The Idustrial Revolution created factories and housing for the peasants and it created a better market and made intelligent men big business men who exploited hundreds making themselves very wealthy. Because of the system lots of money could be made buying labour to make products that could be sold to other workers. Marx saw this new capitalism as unfair where the intelligent ruled the poor and created a new aristocracy who made workers got to work doing a job that was degrading, unfulfilling and where you were not paid a fair wage to make a living. So he came up with the idea of communism where capitalism is destroyed as is any other type of inequality and where the state and all institution disappear. so the Industrial Revolution not only gave birth to progress, wealth and democracy it also gave birth to communism. .

Analyze the role of credit rationing in both a developed country and a less-developed country. How does the role of credit rationing influence economic growth and employment in these two countries? Solution Credit rationing is an action taken by lending institutions to limit or deny credit based on a borrowers\' creditworthiness and an overload of loan demands. Interest rates trending either up or down lead to credit rationing. An example of credit rationing is increasing interest rates about current market rates. Credit rationing IS a pervasive phenomenon. There are two different forms of quantity constraints: micro credit rationing, this places credit limits on borrowers, and macro credit rationing, this randomly denies access to any credit to a fraction of borrowers. The second form has asymmetric treatment of otherwise identical agents. Both forms of rationing can coexist, and play complementary yet distinct roles. It becomes clear that the second form of rationing gains in importance when the information flow within the lending community is poor (thus defaulters have a fair chance for escaping detection). One lesson that comes from both debt overhang and enforcement theories is that the distribution of bargaining power among lenders and borrowers has strong implications for the degree of credit rationing, effort levels as well as efficiency. The effect is similar in both cases .

Encapsulation process. Explain this process giving specific detail at each layer of the OSI Model. Be sure to explain the different PDUs at each stage and include the most significant fields for each pdu. (20 marks) Solution Its dvided into seven layers. Encapsulation happens seperately at different levels. Starting frm Application layer, application running on source device creates some kind of data.Then next comes Presentation layer where encryption gets added to the data. Then the session layer where session id is applied.Upto this point information is still one block of data. Next layer is transport layer where bock of data gets break down into segments and gets a port number. This segment is then passed to Network layer where source and destination IP address are appended and now the segment becomes packet.This packet is then passed to next level called Data link layer where destination MAC address and CRC is added.Now the resulting thing is Frame. The Frame then is sent to the physical device where it is translated into some kind of a signal, whether itâ€™s electrical, radio wave, light or other signal. This Frame then becomes some kind of a signal that represents a series of zeros and ones. This is why at the Physical layer we often call it Bits .
