Changes in Tourism
Geography Essay- Factors Affecting Tourism Describe the changes in the growth in tourism in recent decades. Explain the factors responsible for this. In the 1950s, there were 25.5 million of international tourist arrivals and mostly were Europeans, which were 16.8 million arrivals. However, in the 1990s, international tourist arrivals increased to 455.9 millions. The significant changes were 280.6 million arrivals were from middle-east and 57.7 million arrivals were from Asia-pacific. First of all, transportation is one of the major factors seriously affecting each country's tourism because countries without high efficiency of transportation, it would lower tourists preferences to visit a specific country. For instance, development of the High-speed rail industry in Europe attracts more tourists from Europe continent of even internationally because High-speed trains were also quite fast, which can travel more than 250km/h in average. And travelling by trains was relatively cheaper compared to travel by planes because roundtrip tickets from London to Paris in Euro star cost $1575.6 HKD. However, air roundtrip tickets from London to Paris cost $2484 HKD in British Airways. Secondly, development of infrastructure- both roads and airports in More Economic Developed Countries (MEDCs) and Less Economic Developed Countries (LEDCs) were improving, which allowed more large sizes of
Tropical Rainforest Case Study
Sasha Zouev IB, 16/11/05 Tropical Rainforest Case Study, Amazonia Introduction Tropical rainforest, temperate coniferous and deciduous woodland forests are the three main categories of forest type. Tropical rainforests are considered a much richer species that the other two, and temperate vegetation is one that grows fastest. The rainforest ecosystem is very weak and easily unbalanced, making this type of forest more "permanently destroyed" than the other two. The importance of tropical rainforests lies within the fact that they are the earth's richest source of life as they play a vital part in the earth's natural cycles of soil, water and air through the process of photosynthesis. In this case study we will be looking closely at the tropical rainforest in the Amazonia region of South America. Where is this Rainforest? The term, Amazon rainforest, is used to basically talk about the moist and broadleaved region of what is known as the Amazon Basin, which is around 7 million km squared and covers areas of mainly Brazil, Colombia, Peru and many more South American countries. This rainforest accounts for around 50% of the world's remaining rainforests. Amazonian rainforests contain the biggest and most species-rich tract of tropical rainforest that there is to be found. It is the world's greatest natural resource - the most powerful and bio-actively diverse
Experiment to investigate the effect of different antibiotics on the bacteria Bacillus subtilis:
Experiment to investigate the effect of different antibiotics on the bacteria Bacillus subtilis: Aim: To see which antibiotic (Chloramphenicol, Erythromycin, Fusidic Acid, Oxacillin, Novobiocin, Penicillin, Streptomyan and Tetracycline) reacting with the Bacillus subtilis has the largest zone of inhibition in mm (+/- 0.5mm) and so which has the biggest effect on the bacteria. Introduction: Gram -positive bacteria are bacteria that are dark blue or violet when gram staining. Gram-positive organisms are able to keep the crystal violet stain because of a high amount of peptidoglycan in the cell wall. This makes up about 90% of the thick, more than 20 layers of peptidoglycan together. Gram-positive organisms normally do not have the outer membrane, whereas Gram-negative organisms do. Gram-positive bacteria include many well -known genera like Streptococcus and Bacillus. Most pathogenic bacteria in humans are Gram-positive organisms and these are used to manufacture antibiotics. Bacillus subtilis, also known as the hay bacillus or grass bacillus is a Gram- positive bacterium, which is mostly found in soil. Bacillus subtilis is not a human pathogen and it can contaminate food but rarely causes food poisoning. Bacillus subtilis spores can survive the extreme heat during cooking and Bacillus subtilis is responsible for causing a sticky, stringy consistency in spoiled bread
Examine the strategies used in the transfer of capital between core and peripheral areas
Geography HL Essay: Examine the strategies used in the transfer of capital between core and peripheral areas. There are various strategies which are made use of when transferring capital between the core and peripheral areas. These are mainly loans and debt repayment, remittances, foreign direct investment and the repatriation of profits. Loans and debt repayment is used worldwide in which the developing countries collectively owe $2.3 trillion to foreign creditors. The advantages brought by such a transfer of capital between core and peripheral areas is the opportunity countries get to finance necessary resources in order to build up and develop themselves by improving their education and housing in Sub-Saharan Africa for example. The total money owed has however been cut due to the HIPC plan which reduced the 218$ billion owed to $180 billion. As a result of these loans and repayments, food, clothing, housing, medicines and medical care became cheaper and simultaneously, their quality improved since earlier times. This as a result makes it easier and better for LEDCs to afford such resources, benefiting their standard of living and development of their economy. The loans and debts still however need to be repaid, and as a result countries will need to pay interest on this and pay back the principal. Even bad loans will have to be repaid, and especially for LEDCs this can
How far do Trotsky(TM)s own misjudgments account for his failure in the power struggle which followed Lenin(TM)s death?
"How far do Trotsky's own misjudgments account for his failure in the power struggle which followed Lenin's death?" Following Lenin's death in 1924, a power vacuum appeared for the leadership of the Communist Party in Russia. A collective leadership was proclaimed, however competition for individual authority between Trotsky, Stalin, Kamenev, Zinoviev, Bukharin, Rykov and Tomsky led to a fierce struggle for power, ending in Stalin's triumph and the beginning of his tenure as the leader of the Communist Party. The strongest contenders in the power struggle were Stalin and Trotsky, however a number of unfortunate decisions and lack of support on Trotsky's part, coupled with Stalin's tactics and power base, led to Trotsky's defeat and exile. It was the latter of the two factors that contributed more to Trotsky's ultimate failure, due to the fact that Stalin's initial position was stronger, and his opportunism allowed him to take advantage of Trotsky's misjudgments, thereby allowing him to take power. However, it is worth noting that the term 'misjudgments' is relative to the historian, since a number of Trotsky's unsuccessful decisions were deliberately made to avoid certain outcomes, therefore cannot accurately be termed 'misjudgments'. Trotsky, although he had a limited power base made up of mostly radicals and students, was in a position of adequate leverage immediately
Examine the causes and the effects of biodiversity loss in the Tropical Rainforests
Examine the causes and the effects of biodiversity loss in the TRF Biodiversity can be defined as the variety of all forms of life on earth (plants, animals and micro-organisms). The tropics are the richest areas for biodiversity as tropical rain forests contain over 50% of the worlds species in just 7% of the worlds land. They account for 80% of the world's insects and 90% of its primates. Even though biodiversity benefits us humans in countless ways we tend to be oblivious to this fact and instead, the biodiversity on earth is gradually diminishing. There are many reasons for the loss of biodiversity and the most prominent include Globalization & Cattle Ranching, Hydroelectric Power (HEP), Migration and Logging. Similar to how there are numerous causes for the loss of biodiversity, these causes also have many drastic effects. As mentioned in the introductory paragraph, globalization and cattle ranching is one of the major causes for the loss of biodiversity. Globalization can be defined as the world coming together for trading purposes. This contributes to the loss of biodiversity as globalization is directly linked with deforestation. For instances, huge global corporations like McDonalds own countless amounts of cattle which are often located in deforested areas. In addition to this, much forest land in the Brazilian Amazon is also deforested in order to enable the
Population Case Study - Japan
Sasha Zouev Geography IB, 13/09/05 IB Case Study: Japan (MEDC) Population, Distribution, Density Introduction: Japan is a great example of an MEDC with a particular population pattern and distribution. The country, located on the western edge of the Pacific Ocean lies to the east of Asia and is made up of about 3,000 smaller islands. There are several large main islands including, from top to bottom, Hokkaido, Honshu (the biggest), Shikoku and Kyushu. Japan is also interestingly rated 10th in the world by population count and has an area of about 377,835 km². The aim of this case study is to examine, section by section, the different factors that affect Brazilian population growth and distribution by looking at areas such as geographical positioning, politics, history, and generate some sort of conclusion Distribution: Japan's population is mostly concentrated alongside the south and west coast (figure 1). Japan's population density is ranked 18th in the world, and has assisted in advertising very expensive land prices. From the years 1980 to 1987, prices of land in the six largest cities nearly doubled. This prevents many poorer families from ever purchasing or renting housing in the central cities. Because of this, daily transportation for many workers became a real lengthy hassle. For example some daily commuters had to travel up to four hours total to reach
Effect of substrate concentration on catalase activity (Biology IA)
Title Effect of substrate concentration on catalase activity Aim To prove that at different concentrations of hydrogen peroxide, the rate of catalase activity in chicken liver differs. Hypothesis When chicken liver is exposed to hydrogen peroxide, the higher the concentration of the solution, the faster the activity of catalase because the decomposition rate of hydrogen peroxide increases when its concentration is higher (in the presence of chicken liver). Variables Independent Variables * Concentration of hydrogen peroxide Dependent Variables * Time taken for coloured liquid to rise by 5cm against different concentrations of hydrogen peroxide Controlled Variables * Amount of chicken liver used - cubes cut with a scalpel to approximately 1cm x 1cm x 1cm * Amount of hydrogen peroxide used - 5cm3 measured with a syringe before addition to the chicken liver * Temperature of liver (not controlled) * Age of liver (not controlled) * Source of liver (not controlled) Materials and Apparatus Materials: Apparatus: * 6x Chicken Liver Pieces - 1cm x 1cm x 1cm * 5% Hydrogen Peroxide Solution (5cm3) * 4% Hydrogen Peroxide Solution (5cm3) * 3% Hydrogen Peroxide Solution (5cm3) * 2% Hydrogen Peroxide Solution (5cm3) * 1% Hydrogen Peroxide Solution (5cm3) * 0.5% Hydrogen Peroxide Solution (5cm3) * Coloured Liquid * Distilled Water * 3x 20cm3 Syringes * 1x
The effect of temperature on amylase activity
Kiu Yi, IP 13M The effect of temperature on amylase activity Introduction The purpose of this experiment is to investigate if temperature will affect the amount of starch broken down as enzyme activity can change by different temperature. This is because as temperature rises the rate of chemical reactions increases due to the temperature increases the rate of the molecules' motion. More interactions will be existed between an enzyme and its substrate. The enzyme used in this lab exercise is amylase, which is commonly found in saliva and germinating seeds, catalyzes the breakdown of starch. It also reacts quickly when heat is present during the process of it reaction. However, if the temperature is higher than the optimum point, enzymes can be denatured and they can no longer bind to a substrate and catalyze reactions. My hypothesis is therefore the amylase activity would increase as the temperature rise, until a certain high temperature at which the amylase would denature and be non-functional. In this experiment, I will observe the activity of amylase by using iodine as iodine reacts with starch to form a dark brown/purple color. After adding in iodine, when amylase breaking down starch, less and less starch will be present and the color of this solution will become lighter and lighter. Equipments • 0.1% Amylase 0.5 ml • 1% Starch 5ml • 10 Test tubes and
Describe and explain how the improvement in transport over the last 50 years has increased the global interactions between countries.
Describe and explain how the improvement in transport over the last 50 years has increased the global interactions between countries (10 marks) Transportation is one of the main influences of the development of global interactions between countries. Over the years, transportation allows urban areas to expand, permit regional economic development and overcome the effect of distance -further developing universal communication. There are many forms of transport -road, rail, ocean, air and pipelines. In this essay, by comparing both ocean and air transportation and analysing the various advantages, we can see how the improvements in transport over the last 50 years has increased the global interactions between countries. First of all, although water transportation is considered to be quite expensive, however, it is fairly at a reasonable price as ocean shipping is able to bear more cargos than other forms of transport. The higher capacity enables more goods to be shipped at once which further improves trading activities, making it faster and more efficient. Besides that, free ports are available now in certain countries which attract more imports that can be manufactured into goods that are than exported without having to pay duties or tax. This allows more trading activities to take place without having to fuss over taxes and other additional payments. Moreover, more imports
