Use these ideas to create original and relevant topics to find effective solutions as well as present interesting facts. Sample Essay: Reasons Why Animals and Plants Extinct At times, all we need is to see how to compose an assignment with our own eyes. The practice is not the same as the theory. Many theoretical aspects look good only when spoken. They are different when it comes to the writing process. Therefore, you should read some examples to understand how to put the things together. Unfortunately, more and more species of animals and plants are threatened and may potentially disappear. The history of our planet knows multiple grievous cases when we lost the representatives of flora and fauna. What can be done to prevent the extinction? This question should be on the mind of everyone. The humankind should protect animals and plants from extinction, and the first step is to realize the factors that lead to this terrible process. Scholars have grievous predictions. They believe there will take place another extinction of species before the year 2050. This was stated in National Geographic News. The reasons for that are various, and it’ll be triggered naturally and by the human factor. It is well-known that the disappearance of the slightest species may lead to destabilization of the natural processes, and the planet will go through a catastrophe. The negative reflection will be echoed for everyone. Undoubtedly, this process must be stopped at any cost. In order to succeed in this matter, we should understand the possible reasons. One of such is deforestation, which is caused by mass urbanization. People have no place to live in, and they cut the forest. Nevertheless, it leads to a loss of its habitats. Nearly 36 million acres of woods are being cut yearly. This is a huge mistake. Another factor is global warming. The so-called green effect negatively influences temperatures, which induce warming throughout the globe. In turn, this melts down ices and negatively affects plants and animals. Even 1 degree may carry danger. Besides, the amounts of carbon dioxide increase as well. Scholars theorize that the process may lead to the disappearance of 56,000 plant and 3,700 animal representatives. Another great mistake is the introduction of animals and plants that are not native in some regions. Our race wishes to spread them throughout the planet. Nevertheless, they cannot adapt to the new surroundings and pass away. Besides, overexploitation, likewise, makes its deadly contribution. The excess exploitation of definite areas leads the environment to exhaustion, which also kills many animals and plants. This should be done reasonably. All these facts show us that the human race destroys many representatives of flora and fauna. We should recognize and avoid such actions. There is still time to cure the damage done. It’s not possible to stop certain processes as they are needed for the surviving of the humanity. Nonetheless, some alternatives should resolve the issue. Try to remember this sample and craft the similar ones. Of course, one example may be not enough. You are welcome to read other effective samples on the biology themes. This provides you with additional information and helps to compose really meaningful and impressive dissertations. Don’t forget to improve your writing skills. Learn all academic demands concerning dissertation writing and work out every stage with a high level of dedication. Use universal tips to turn your dissertation into the real masterpiece.

Bimetallism Definition and Historical Perspective

Bimetallism Definition and Historical Perspective Bimetallism  is a monetary policy wherein the value of a currency is linked to the value of two metals, usually (but not necessarily) silver and gold. In this system, the value of the two metals would be linked to each other- in other words, the value of silver would be expressed in terms of gold, and  vice versa- and either metal could be used as legal tender.   Paper money  would then be directly convertible to an equivalent amount of either metal- for example, U.S. currency used to explicitly state that the bill was redeemable â€Å"in gold coin payable to the bearer on demand.† Dollars were literally receipts for a quantity of actual metal held by the government, a holdover from the time before paper money was common and standardized. History of Bimetallism From 1792, when the  U.S. Mint was established, until 1900, the United States was a bimetal country, with both silver and gold recognized as legal currency; in fact, you could bring silver or gold to a U.S. mint and have it converted into coins. The U.S. fixed the value of silver to gold as 15:1 (1 ounce of gold was worth 15 ounces of silver; this was later adjusted to 16:1). One problem with  bimetallism  occurs when the face value of a coin is lower than the actual value of the metal it contains. A one-dollar silver coin, for example, might be worth $1.50 on the silver market. These value disparities resulted in a severe silver shortage as people stopped spending silver coins and opted instead to sell them or have them melted down into bullion. In 1853, this shortage of silver prompted the U.S. government to debase its silver coinage- in other words, lowering the amount of silver in the coins. This resulted in more silver coins in circulation. While this stabilized the economy, it also moved the country towards  monometallism  (the use of a single metal in currency)  and the  Gold Standard. Silver was no longer seen as an attractive currency because the coins were not worth their face value. Then, during the  Civil War, hoarding of both gold and silver prompted the United States to temporarily switch to what’s known as â€Å"fiat money.† Fiat money, which is what we use today, is money that the government declares to be legal tender, but thats not backed or convertible to a physical resource like metal.  At this time, the government stopped redeeming paper money for gold or silver. The Debate After the war, the  Coinage Act of 1873  resurrected  the ability to exchange currency for gold- but it eliminated the ability to have silver bullion struck into coins, effectively making the U.S. a Gold Standard country. Supporters of the move (and the Gold Standard) saw stability; instead of having two metals whose value was theoretically linked, but which  in fact fluctuated because foreign countries often valued gold and silver differently than we did, we would have money based on a single metal that the U.S. had plenty of, allowing it to manipulate its market value and keep prices stable. This was controversial for some time, with many arguing that a â€Å"monometal† system limited the amount of money in circulation, making it difficult to obtain loans and deflating prices. This was widely seen by many as benefiting the banks and the rich while hurting farmers and common people, and the solution was seen to be a return to â€Å"free silver†- the ability to convert silver into coins, and true bimetallism. A Depression and a  panic in 1893  crippled the U.S. economy and exacerbated the argument over bimetallism, which came to be seen by some as the solution to all of the United States’ economic troubles. The drama peaked  during the  1896 presidential election. At the National Democratic Convention, eventual nominee  William Jennings Bryan  made his famous  Ã¢â‚¬Å"Cross of Gold†Ã‚  speech  arguing for bimetallism. Its success gained him the nomination, but Bryan lost the election to  William McKinley- in part because scientific advances coupled with new sources promised to increase the supply of gold, thus alleviating fears of limited money supplies. The Gold Standard In 1900, President McKinley signed the  Gold Standard Act, which officially made the United States a monometal country, making gold the only metal you could convert paper money into. Silver had lost, and bimetallism was a dead issue in the U.S. The gold standard persisted until 1933, when the  Great Depression  caused people to hoard their gold, thus making the system unstable; President Franklin Delano Roosevelt  ordered all gold and gold certificates to be sold to the government at a fixed price, then Congress changed the laws that required settlement of private and public debts with gold, essentially ending the gold standard here. The currency remained pegged to gold until 1971, when the â€Å"Nixon Shock† made then U.S. currency fiat money once again- as it has remained since.

Ga Kpanlogo and Ewe.Traditional West African dance and music Research Paper

Ga Kpanlogo and Ewe.Traditional West African dance and music techniques - Research Paper Example Comparison of Ga Kpanlogo and Ewe Drumming culture Ga Kpanlogo and Ewe are more or less Ghanaian cultures and they are West African in nature. Ga Kpanlogo has its origin in the capital city of Ghana, Accra, given this is the traditional home of the Ga people whose culture is manifested here (Lewis 2002, p.5). This type of dance can be termed as the urban youth dance and drumming. In addition, it is mainly a symbol of commitment among the rapidly growing youth in the capital of Ghana. This is due to the advocacy nature of the culture while trying to shape the political vision of the post-colonial Africa (Music 2001, p.10). Ewe music and drumming, on the other hand, are a combination of musical and drumming activities of the Ewe people of Ghana, Togo and Benin. This community throughout West Africa is known for drumming and their mode is in the form of a sophistication of cross rhythms and polyrhythm borrowing some of their similarities from jazz and Afro-Caribbean music. This form of drumming embraces diversity and therefore, the drums and music are played in so many different ways depending on where the group playing it originates. The Ewe drumming culture is composed of several drums, a bell and a rattle, and this will be different from Ga Kpanlogo, which is generally composed of drums. Each group of complete Ewe drumming is composed of a master drum together with other secondary drums and an iron bell (Lewis 2002, p.8). The Ewe people do not only have a complex drumming culture but also a complex way of their living. One of their beliefs is that if one person is good at drumming and dancing, then i t is because they inherited it from an ancestor who was good at it. It is important to realize that for both the Ga Kpanlogo and the Ewe music systems, they exhibit 16 voices in their voice notations in terms of their female and male voices. It is notable that the music and drumming cultures of the two societies have some aspects in common. The two forms of drumming and music relate to the belief systems of their respective societies. For example, in the Ewe people music helps them reconnect with their ancestors as they feel the power of life. The aspect of ancestors is quite fundamental to the people of Ewe as they possess the ability to define an individual’s destiny, hence they must be pleased through music (Music 2001, p.13). Secondly, both the group music and drumming culture are aesthetic. For example, the Ewe considers powerful music as good music. This is as the force of drumming helps people remember their past victories as very important concepts. The drumming and m usic of the two communities are a significant symbol of their history as well. In the past for example, drumming helped the Ewe people achieve their freedom from their captors through the blessings from their ancestors (Burns 2006, p.24-6). According to this culture, music is a destiny manifested as a gift from the ancestors. For the two communities, music is used for and during special functions such as during war, at funerals and for rituals for the ancestors in the society. After such functions are over, other genres are put in place for continuity (Rentink 2002, p.31-8). Ga Kpanlogo, as played by the Ga ethnic group most of whom live in Accra, existed in the recreational dance and music. It has since spread as bushfire throughout the country, which began just as a mere creative dance (Agawu 1987, p.9). As opposed to the Ewe dance and music, which were influenced by Afro-Caribbean music and jazz, this form of

Banking Concept of Education Paulo Freire Essay

Banking Concept of Education Paulo Freire - Essay Example Freire demonstrates that the banking concept is considered by oppressors to be the most suitable method of imparting knowledge on learners. The banking concept is where knowledge is deposited the same as how money is deposited in a bank. Therefore the application of the banking system of education makes students to be treated as if they are empty vessels which need to be filled with knowledge (Paulo 319). The teacher is the subject in the banking method of education while the student is the subject. This shows a relationship between the teacher and the student where the teacher narrates knowledge with the student being expected to be the listening objects. Paul Freire is opposed to the banking education because it is makes education petrifying and lifeless due to the narration process through which students are expected to learn (Mejia 63). The narration which characterizes the banking education involves teachers filling information or content to students. In this method of education , students are disconnected and detached from reality because they may not find the narrated content to be significant. The students are thus made to memorize content without attaching any importance to it. On the other hand, the problem posing method of education involves both the teacher and the student in solving problems during learning. The teacher and the student therefore work together and hence both play equal roles in the process of knowledge acquisition without the student being the object into which information is filled. The student is enabled to engage in the learning process and thus making the problem posing method of education realistic because students are able to engage with the reality of the content being learned. Unlike the oppressive banking method of education, the problem posing approach enables learners to act as thinking beings

Cells Biological Essay Example for Free

Cells Biological Essay I) Observation of starch grains 1. A potato was cut by using a cork barrier to obtain a piece of it. 2. The small piece of potato was placed on the centre of the glass slide and enough pressure was applied with fingers to squeeze it until small amount of juice was force out. The piece of potato was discarded leaving the juice behind on the glass microscope slide. 3. A drop of water was added to the potato juice and the glass slide was then covered with a clean cover slip. 4. The slide was examined: under low power (10X), then high power (40X). A drawing of 4-6 starch grains was made to illustrate the shape and other observable details for each, low power (10X) and high power (40X). 5. The experiment was preceded by staining the grains using the irrigation technique. (Irrigation technique: A drop of iodine was placed at one edge of the cover slip. A filter paper was brought into contact with the water at the opposite edge of the cover slip. As water was absorbed by the filter paper, iodine on the other side of the cover slip was drawn underneath it and the sample was stained.) 6. The iodine-stained mount was examined under low power (10X) and high power (40X). 4-6 starch grains were drawn to illustrate their shape and structure. These drawings were included in the microscope data sheet as results. II) Observation of onion cells 1. An onion was cut into half and one of its fleshy scale petals was removed. 2. The onion petal was snapped backwards and a forceps was used to tear away a piece of thin epidermal lining from inside the onion. A 1cm square piece of lining was placed onto the microscopic glass slide. 3. A drop of water was placed on the onion epidermal lining and the lining was covered with a cover slip. It was examined under a microscope at low power (10X) and then high power (40X). A drawing of the observations was made. The details that were observed in the preparation were included. . The parts of the onion cells were labelled accordingly. 4. The experiment was preceded by staining the onion lining with iodine by irrigation technique as described earlier. 5. It was examined again under low power (10X) and high power (40X). 4-6 onion cells were drawn in the microscope data sheet as observation. The parts of the onion cells were labelled completely. III) Observation of cheek cells 1. A clean glass microscope slide was obtained and a drop of water was placed in the centre of the slide. 2. A flat toothpick was hold against the inner cheek and the inner cheek was gently scraped with the flat edge of a toothpick. The cheek cells were spread in the drop of water on a microscope slide. 3. The specimen was covered with a cover slip and air bubbles were avoided. 4. It was observed under high power (40X) and a drawing of 4-6 cells was made. 5. The details that can be observed in the preparation were included and were labelled accordingly. 6. The experiment was preceded by staining the cheek cell slide with methylene blue by irrigation technique. 7. The cell with structures observed was drawn in the microscope data sheet as part of the results. Nucleus, nuclear membrane and cell membrane were labelled. Discussion: Under microscopic examination, organelles of the cell are enlarged to be observed. In onion cells (plant cell), cell wall, cell membrane, cytoplasm and nucleus are observed. In cheek cells (animal cells), cell membrane, cytoplasm and nucleus are observed. The difference between plant cells and animal cells are presence of organelles and their cell shape. From the observation of onion cells and cheek cells, it there is presence of cell wall in onion cell (plant cell) but it is absent in animal cell .The presence of cell wall contributes to the fixed, rigid shape of plant cell whereas animal cell is irregular in shape. Different types of stain colour for particular parts of a cell respectively so that the translucent parts of the cells can be viewed more clearly and can be studied easily. Iodine is often used as an indicator for starch. Hence, starch grains and onion cells are more clear and visible when iodine stains starch present in the cells. During observation of starch grains, starch is mixed with iodine solution where dark blue solution is observed, representing a starch/iodine complex. Staining a plant cell with iodine allows us to see the onion cell wall. Methylene blue binds well with negative charge molecules (DNA) which allows us to see the nucleus of the cell. It stains nuclei acid found in the nucleus, making nucleus more observable. For precaution, glass slide is make sure is clean and perfectly transparent by holding the slide by its edge. Glass slide is make sure not to be dry so that the cell can be observed under the microscope. During wet mount, air bubbles that will interfere the viewing the organisms’ movement is to be avoided by putting the covers lip gently on the slide. When observing the specimen, adjust the iris diaphragm or light level to achieve optimum contrast. Low power is always to be used first as to know the location of a good area for observation.

Poverty: A Form of Slavery Essay -- poverty essay

Today they say that we are free, Only to be chained in poverty -- Bob Marley This paper will discuss poverty, the different types of poverty and their definitions and who is affected by each type of poverty. It will look at the some of the major reasons why poverty exists and what causes poverty, like such things as inequality, stratification and international debt. Some of the impacts of poverty will also be analyzed from a national and global perspective; things like education, literacy rate, and crime. This paper will demonstrate that poverty affects almost everyone in some form or another and exists because those with power and wealth want and need poverty to exist to force a dependence on the wealthy. A few of the main approaches that this is achieved is through economic systems, influencing government policies, and global stratification. Defining poverty is not a simple task and this is what this paper will tackle first. WHAT IS POVERTY Poverty is difficult to define exactly, as it has different meanings to different people depending on what country they live in, what culture they belong to, and how much income they earn. All these factors and more will change the way poverty is defined by an individual or organization (Seabrook, 2007, p.35). Adam Smith the classical economist had this view of poverty â€Å"poverty is a lack of those necessities that the custom of the country renders it indecent for creditable people, even of the lowest order, to be without† (Richmond and Saloojee, 2005, p.33). Another popular view of poverty is that of Nobel Prize winner Amartya Sen who said the poor â€Å"cannot participate adequately in communal activities, or be free of public shame from failure to satisfy conventions† (Richmond and ... ... of slavery.

Investment Property Essay

The objective of this Standard is to prescribe the accounting treatment for investment property and related disclosure requirements. Investment property is property (land or a building—or part of a building—or both) held (by the owner or by the lessee under a finance lease) to earn rentals or for capital appreciation or both, rather than for: (a) use in the production or supply of goods or services or for administrative purposes; or (b) sale in the ordinary course of business. A property interest that is held by a lessee under an operating lease may be classified and accounted for as investment property provided that: (a) the rest of the definition of investment property is met; (b) the operating lease is accounted for as if it were a finance lease in accordance with IAS 17 Leases; and (c) the lessee uses the fair value model set out in this Standard for the asset recognised. Investment property shall be recognised as an asset when, and only when: (a) it is probable that the future economic benefits that are associated with the investment property will flow to the entity; and (b) the cost of the investment property can be measured reliably. An investment property shall be measured initially at its cost. Transaction costs shall be included in the initial measurement. The initial cost of a property interest held under a lease and classified as an investment property shall be as prescribed for a finance lease by paragraph 20 of IAS 17, ie the asset shall be recognised at the lower of the fair value of the property and the present value of the minimum lease payments. An equivalent amount shall be recognised as a liability in accordance with that same paragraph. The Standard permits entities to choose either: (a) a fair value model, under which an investment property is measured, after initial measurement, at fair value with changes in fair value recognised in profit or loss; or (b) a cost model. The cost model is specified in IAS 16 and requires an investment property to be measured after initial measurement at depreciated cost (less any accumulated impairment losses). An entity that chooses the cost model discloses the fair value of its investment property. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. An investment property shall be derecognised (eliminated from the statement of financial position) on disposal or when the investment property is permanently withdrawn from use and no future economic benefits are expected from its disposal. Gains or losses arising from the retirement or disposal of investment property shall be determined as the difference between the net disposal proceeds and the carrying amount of the asset and shall be recognised in profit or loss (unless IAS 17 requires otherwise on a sale and leaseback) in the period of the retirement or disposal.
