Natural resources- Exam questions
Natural resources- Exam questions ) Natural resource's are those environmental 'goods', including the so-called 'free' goods such as air and water, which are available in nature. It refers to a stock (e.g. A forest), which produces a flow of goods (e.g. New tress). Natural resources can be divided into renewable and non-renewable; the level of flow on non-renewable resources(e.g. fossil fuels) is determined economically and politically. Natural resources are culturally defined- we can change our minds about what to use as well as Changing our technical ability to exploit the environment 2) A resource is any physical or virtual thing of limited availability, or anything used to help one earn a living. As resources are very useful, they have a value to them. Resources help to produce goods so they have economic value. Natural resources like forests, mountains etc. are very beautiful so they have aesthetic value. On the other hand, resources have an ethical value as well because it is our moral duty to protect and conserve them for the future generations. There are 3 Main types of resources these are: Natural resources, Human resources and Capital/Material resources. We can assume that there is an extent to which natural resources are essential to a countries economic development. There are numerous examples where this extent is shown, the first being the Middle East. The
Describe the global growth and geographical distribution of human population. Discuss the impacts that this growth has on both land and water resources?
Environmental Science 36E1 People and the Environment Autumn 2002 Student 1117083 Environmental Science 36E1 People and the Environment Autumn 2002 Student 1117083 Essay Title: Describe the global growth and geographical distribution of human population. Discuss the impacts that this growth has on both land and water resources? In the year 1999 the worlds population reached the 6 billion mark and the United Nations predict that by the year 2025 this will rise to 8 billion with a further rise in 2050 to 9.3 billion before it starts to stabilise at about 10.5 / 11 billion. (Fig 1.0) This exponential growth is a phenomenon that has only really come about during the last three hundred years or so. During prehistoric time the growth of the global population was very slow. However in the last 350 years, human population has dramatically increased, with most estimates indicating that about 90% of the worlds population growth has occurred during this time. Looking at the growth rate on a global scale we can form many opinions relating to the reasons for such an increase. The population growth can be directly attributed to advancements in health care, and hygiene that has resulted from scientific developments that have occurred from the mid eighteenth century to the present day. Such advancements have enabled crude mortality rates to decrease and life expectancy to increase
Business resources D1
D1, Evaluate how managing resources and controlling budgets can improve the performance of a business. If a business manages its physical and technological resources well this would the performance of the business it will give Sainsbury the full benefits of the resources. If Sainsbury manages and controls its budgets effectively then it can improve the performance and success of the business. If a business manages to maximise it income and minimise it cost then it would improve the business profits level which would improve the business performance. If a business manages it cost and budgets properly by purchasing the right stock level which it needs and knows it would sell with a specific period of time then this means that the business would benefit by making substantial sales revenue from those stock as a result. Another benefit is that the business would be saving money from the space needed to hold the stock in the stockroom. Another benefit would be that the business would be making good profits level from the sales. This would improve the performance and success of the business overall. If a business manages its costs efficiently then it would improve the success and performance of the business. If a business employs the right amount of workers it needs then it would reduce the cost of the business. Another benefit if the business employs the right amount of staff
The Human Genome Project
Amira Nicola January, 2001 The Human Genome Project The Human Genome project is a scientific research effort to analyse the DNA of human beings and that of several other types of organism. The project began in the United States in 1990 under the sponsorship of the U.S. Department of Energy and the National Institutes of Health. It was scheduled to be completed in 15 years. The project's goal is to identify the location of every human gene and to determine each gene's precise chemical structure in order to understand its function in health and disease. In the nucleus of every cell in the human body, there are 23 pairs of chromosomes, each of which is composed of several genes. Genes are discrete stretches of nucleotides that carry the information the cell uses to make proteins. The most important component of a chromosome is the single continuous molecule of DNA. This double-stranded molecule, which is shaped as a double helix, is composed of linked chemical compounds known as nucleotides. Each nucleotide consists of three parts: a sugar known as deoxyribose, a phosphate compound, and any one of four bases-adenine, thymine, guanine, or cytosine. These parts are linked together so that the sugar and the phosphate form the two parallel sides of the DNA ladder. This double-helical structure of the DNA molecule was discovered Watson and Crick in 1953, for
Human Impact on the environment
Human Impact on the Environment Both graphs show a positive correlation which means there is a strong relationship between the rises in global temperature to the level of carbon dioxide in the air. It shows from the year 1800 - 2000 the air temperature has increased from -0.1°c to 7°c. This is an important change for the earth's average temperature, although it does not seem like much. The graph is varied where by between the years 1940 to 1980, it decreases and then increases, but the main trend it is that the global temperature is increasing. The second graph, which shows the rise in carbon dioxide, definitely confirms that there is a link between air temperature and carbon dioxide levels in the air. Because the rise in carbon dioxide, creates a greenhouse effect which forms an external layer around the earth, this prevents any of the earths heat to escape, the more this layer thickens the more it will be a disadvantage to the environment. From the year 1880 to 2000, there has been an increase of carbon dioxide in the atmosphere. As you can see on the bar chart above, there has been a major decrease of the thickness of ice in different parts of the arctic sea and in some parts; it has almost reduced half its original size. For example in Canada Basin the thickness of the ice was 3.5 between the years 1958 - 1976 and reduced to 2.1 between the years 1993- 1997. if this
How Do Human and Natural Factors Affect the Global Population Distribution?
Population Distribution-Essay "How do human and natural factors affect the global population distribution?" There are many factors that can affect the way a population is spread over the earth's surface, these factors are what make the spread of the population un-even. The factors are split into two sub categories: human and physical factors, within each of these there are positive and negative factors. I am going to look at a wide range of factors that are thought to affect population distribution and see whether they are positive or negative affects or, they could have both affects. Areas such as Japan which are wealthy and industrial are densely populated, areas like Antarctica which are hostile environments are likely to be sparsely populated. The initial reason for people settling where they do is the resources that were originally available to them. A good example of somewhere which had resources readily available when people first settled there is the south east of England a good example being around London. People settled along the river Thames so there was water available, also the river could be used to transport goods up and down the river, there was `protection because the area was quite woody, the wood also provided fuel also being near to the coast there were good communication links. These basic factors that were there 100's of years ago influenced where
Human Cloning Assignment
Haretha Aydi Access I.T Human Cloning Assignment Introduction: In this assignment, we are to choose a specific subject and write out and argument with and against it. We should also include background information and carry out a research on that specific topic, lastly a conclusion should be set out. Background Knowledge: )- Human cloning: First explored by Spemann in the 1920's to conduct genetics research, nuclear transfer is the technique currently used in the cloning of adult animals. A technique known as twinning exists, but can only be used before organism's cells differentiate. All cloning experiments of adult mammals have used a variation of nuclear transfer. Nuclear transfer requires two cells, a donor cell and an oocyte, or egg cell. Research has proven that the egg cell works best if it is unfertilized, because it is more likely to accept the donor nucleus as its own. The egg cell must be enucleated. The nucleus is removed from the egg cell This eliminates the majority of its genetic information. The donor cell is then forced into the Gap Zero, or G0 cell stage, a dormant phase, in different ways depending on the technique. This dormant phase causes the cell to shut down but not die. In this state, the nucleus is ready to be accepted by the egg cell. The donor cells nucleus is then placed inside the egg cell, either through cell fusion or transplantation.
Explain and illustrate the roles played by profit in allocating scarce resources within the economy over time.
(a) Explain and illustrate the roles played by profit in allocating scarce resources within the economy over time. [10m] Profit being a form of return from risk-taking and entrepreneurship, plays a significant role in allocating limited factors of production (land, capital, entrepreneur, labour) in the economy over time. It acts as a signaling mechanism in the free market system and funds capital investment so as to generate more returns in the future. Furthermore, it serve as an indicator to producers on what and how much to produce, how to produce and for whom to produce. This allows them to allocate scarce resources effectively and hence, maximize profits. Traditionally, the objective of every firm is to maximize their profit. This can be done by producing at the output level where marginal revenue=marginal cost (MR=MC). At this point, the additional revenue that a firm would earn by selling one more unit of good would be equivalent to the additional cost required to produce it. Hence, firms would allocate their resources to increase output till this point as reflected in the diagram A. As shown in Diagram A, producing at output level, Q1 would result in a profit earned reflected by the blue border box. However, the firm is not producing at the optimal output level of Q2 which generate the highest
Human Reproductive System
The Human Reproductive System Structures of the male reproductive system Bulb of penis The bulb of penis is the expanded posterior part of the corpus spongiosum of the penis. It lies in the interval between the crura of the penis. It contains slightly dilated and angulated portion of the urethra. Bulbourethral (Cowper's) gland The bulbourethral gland is pea-sized structures located on the sides of the urethra below the prostate gland. It produces a clear, slippery fluid that empties directly into the urethra. These fluids lubricate the urethra and neutralises any acidity that may be present due to residual drops of urine in the urethra. Corona The corona is a rounded projecting border that forms the circumference of the base of the glans. It is located behind the penis and overhangs a deep retroglancular sulcus Corpora cavernosum penis The corpus cavernosum penis is one of the pair of sponge-like regions of erectile tissue in the penis. It contains irregular spaces which are filled with blood during erection. These spaces are lined by endothelium and separated by connective tissue septa. Corpus spongiosum penis The corpus spongiosum penis is the median column of erectile tissue located between and ventral to the two corpora cavernosa penis. Posteriorly It expands into the bulb of penis and terminates as enlarged glans penis anteriorly. Ductus (vas) deferens The
Human Growth and Development
Social Science and professional Practice Human Growth and Development. In this assignment I will explore psychological theories and how they assist in social work to better understand and work positively with clients. In accordance with the GSCC codes of practice, (2.3) pseudonym names have been used to protect the identity of the family. Robert describes his upbringing being very happy and largely contributory to him developing into a well-adjusted responsible young man. Howe (1995) believes when viewing parent-child interactions, the quality of this relationship can assist in determining the 'level of social competence and developmental pathway through life. Robert reports he was raised feeling loved, secure and trusting of his mother throughout his childhood. As Robert is hoping to become a relative carer for his siblings Camilla and Daley, it is important to acknowledge the grief they may all experience from being separated from their mother. Separation and loss can be seen in the simplest form of '...young children who are separated from their prime caregiver' (Bowlby 1973, p56). Attachment is not the same as dependency and although the intensity of attachment between parent and child decreases with age, it is still significant throughout the life cycle particularly during times of distress and uncertainty and needs to be acknowledged and supported for Robert to
