Microbes Essays - Microbiology, Bacteria, Bacteriology, Extremophile Microbes Can All The Microbes Be Destroyed? Tina Marie Partin Somerset Community College Bio 226 Principles Of Microbiology Dr. Md. Jahurul Karim 2/07/2012 Can All The Microbes Be Destroyed? With all the emerging technology which allows us to study and understand microbes, it is now imperative to ask ourselves if destroying all the microbes on earth would be a possibility. The answer is no. Destroying all microbes on earth would not only be impossible, it would be impractical. Microbes assist humans and the earth in many ways, such as making food edible, maintaining normal flora in the human body, microbes are also used in many modern medicines, and lastly microbes are involved in cycling vital elements such as carbon and nitrogen, breaking down wastes and dead organisms into simpler substances plants can use in photosynthesis (Cohen 2002). Although microbes benefit us in so many ways, many scientists today have pondered destroying all microbial life. Thankfully, due to the hardiness and the will to survive, most microbes have certain characteristics which would allow them to survive extinction. Not only would microbes have the ability to fight back, microbes behave so d ifferently that destroying them with one source would be impossible. If the world did have all the technology needed for the destruction of all microbes including infectious diseases, it would become a deserted waste land that would not be suitable for life. In order to understand why microbes would survive an assassination attempt, we must understand what characteristics microbes have that would ensure their survival. Destroying all microbial life is impossible due to the characteristics of most microorganisms. Like most living things, microbes have many characteristics that would allow them to survive destruction. For example, some of the most extreme survivors of microbes are known as extremophiles. These microbes have been found living in a few inches below the surface in suspended animation without water. The microbes that can survive without water have activated a sequence of DNA, which compensates for lack of water. Scientists have also found microbes that survive beyond -100? F; these psychrophiles have a remarkable cellular ingredient that prevents the formation of ice crystals, while others huddle together into mats of biofilms. Other microorganisms however have evolved a love for heat. Miles below the ocean?s surface, scientis ts have recently discovered organisms thriving in unforgiving territories where temperatures exceed 600? F. In this kind of dark landscape photosynthesis is not a possibility so certain kinds of single-celled archaea have developed a unique alternative called chemosynthesis: a means of converting inorganic hydrogen sulfide dissolved from rocks into food. And finally when it comes to acidity, human?s blood has to stay between 6.8 and 7.8 to support life. But scientists have found microbes in Yellowstone National Park that were adapted to a pH of 10. These microbes have the ability to keep the pH inside their cells neutral. With extreme characteristics such as these, microbes are determined to ensure their survival (Cohen 2002). After understanding some of the extreme characteristics of certain microbes, it is imperative that science must understand that destroying microbes by one source would be impossible. It is estimated that microbes have been around for billions of years, so they have endured some of the most extreme types of life. When we look around we don?t see microbes but they are everywhere. They around us, they are on us, they are in us. Most of us understand that if we destroy microbes, we destroy ourselves. Let?s just pretend for a moment that human life does not need the imperative essentials provided by microbes and we can do without them. So now the question is: How are we going to destroy them. From the information above we see that some microbes have the ability to survive the most extreme of heat, some survive the most extreme of cold, some doesn?t need water at all, and some live in the most extreme of acidic levels. Also many viruses live inside our own cells, so we could not kill them without destroying ourselves. It seems that evolution has solved many problems, except immunity against viral or bacterial invaders. Another thing that some microbes due to ensure their survival against attack is that they will shed their pathogenicity even under dire conditions

Nigerias Business Environment Essay Example | Topics and Well Written Essays - 1250 words

Nigerias Business Environment - Essay Example Misrule compounded by corruption and uncertainty are wrecking chances for development in Nigeria (Iba, Louis; 2009). The image of Nigeria is one of poverty and anarchy. This is largely due to unemployment and political uncertainty. Except for oil and gas the country is known for little else although natural resources are in abundance. Population below poverty line is shown as 70%. The country keeps showing results and returning to shambles in turns. Nigeria has not shown consistency in economical reforms although it has made attempts to project oil and other natural resources for potential foreign investments (Doing Business in Nigeria, 2007). There is inconsistency in the business environment. It has not shown any progress in clearing IMF debts. IMF had instructed stringent measures to revive economy that included reforms in the banking sector (Nigeria Economy 2010). Well-informed Nigerians rue the years of instability since the 1950s when oil was discovered in Nigeria. However, people are poor and spend more time on earning for their daily necessities. Revenues from oil are spent on balancing for various loans taken for infrastructure. Talking of infrastructure, the country's aspirations for establishing railway network has not resulted in any concrete action. This has given rise to facilitating transportation by roads. However, majority of the roadways are in poor shape resulting in traffic snarls. The civilian government of the day is doing all it can to project the country as a safe and conducive destination for business. However, their clarion call is not yielding the desired effects. Western powers are cool to investing in a nation where political status is still seen as unstable (Nigeria Economy 2010). Western economies have shied away from directly doing business in Nigeria leaving it to Asians. Asians have been more forthcoming from the 1970s and enjoyed the fruits of doing business in Nigeria. Japan has showed some interest in doing business in Nigeria (Bala, Dr Julius J; 2003). Today, Nigeria is a progressive economy. However, the country is experiencing setbacks so it is unable to meet projected economical targets. The country needs to act on its initiatives for economical turnaround with gender-based schemes to attract greater foreign investment and participation (Nwoye, May; 2007). In spite of the political and economic status, Nigeria has a vibrant and innovative population. It is this effervescent attitude that provides the best hope for appropriate business environment in a country torn by decades of mistrust among its two main communities Islamic and Christianity. Business Prospects in Nigeria When President Olusegun Obasanjo was sworn in on 29 May 1999 his reformative measures instilled confidence and attracted foreign investments. Obasanjo quietly

Media imperialism PowerPoint Presentation Example | Topics and Well Written Essays - 750 words

Media imperialism - PowerPoint Presentation Example Media imperialism and cultural imperialism pose great negative effects not only to the local media but also the consumers of the content. The local media stand to lose since they may be swallowed or taken over by large media corporations. According to (Desai and Agrawa 2009, p. 19) cultural –media imperialism theories had predicted that the importation of television channels would lead to demise of local cultures and cultural industries without considering complex patterns of television production, distribution and consumption. Generally, a perception of cultural consequence of the control of various media products is based on a view that mass media as primarily manipulative agents capable of having direct, unmediated effects on the audience behavior and world view (Tomlinson 2002). He asserts that there are also good reasons for cultural-media imperialism especially for the Marxists in understanding domination of the media. The consumers tend to be influenced by the cultures of the dominant media. Such culture influence may be a threat to the National security of a Nation especially where the culture of terrorism is inculcated in the minds of the local consumers. In addition to this effect, the contents of the dominant media can also be biased. The media content may not capture the more pressing issues of the home country instead focus on the world news. In most cases world news coverage may not be of importance to the consumers of the home country. Such a state is dangerous to a state.

An examination of the attitudes of parents towards the impact of play Essay

An examination of the attitudes of parents towards the impact of play in the Foundation Stage - Essay Example (Wiltshire, 2002). This paper considers whether parents are aware of the educational importance of play in the foundation stage curriculum. Interviews were used to collect data from parents of children who attended either a nursery, or reception class of a foundation stage setting in one infant school. Results indicated that although parents were aware of the social benefits of play, in some cases they were unaware of the other areas of a child’s development. Findings were organized and analysed according to four themes namely behaviour, educational and spontaneous, play and learning, and the social benefits of play. These were related to current literature in the area of early years education, and recommendations for future practice are also considered. This enquiry will seek to determine the extent of parents’ awareness and understanding of the educational value of play in the Early Years Foundation Stage (EYFS) curriculum. Furthermore, the enquiry will specifically outline and discuss concerns with how parents of children in an early years setting, understand and value the importance of play in the early years curriculum. In addition, the enquiry will review the academic literature in the area of early year’s education and seek opinions of some regarding the current definitions of play. As an early year’s specialist, it is important to be aware of the importance of play in the early year’s sector. From personal experience it has been observed that although parents are often very supportive of the play-based curriculum for nursery children, many parents become overly concerned about the lack of reading books and homework when their child reaches reception. Therefore the enquiry will discover how parents believe children benefit from play and will attempt to gain insight into how much parents understand about the value of play. Finally, this enquiry will be significant in

Effects of Water Temperature on Plant Growth

Effects of Water Temperature on Plant Growth Abstract   Test the affect of microwave water and boiled water on plants. No major difference of the plants growth between boiled and microwave water, shown in the results. 1.0 Introduction The following experiment was conducted over a period of 5 weeks testing 2 different plant species on the affects of microwave water, behind the theory of microwave radiation altering the chemical composition of water. Based upon this theory the plants were experimented to see if microwave radiation alters the structure of DNA affecting the growth of plants. [Research Centre, 2006] Two hydrogen atoms and one oxygen atom is the very simple atomic structure of water. Causing it to have unique electrochemical properties. A slight positive charge on the hydrogen side of the molecule, with a negative charge on the other side. Water is a powerful solvent and is responsible for its string surface tension, as the molecular polarity causes water molecules to arrange themselves in patterns when a physical phase changes in water molecule. Specific heat is the energy amount required to change the temperature of a substance and wast has high specific heat. Large amount of heat energy, before it begins to get hot as its high specific heat. Helps organisms relate their body temperature as it releases energy slower and more effectively when caused to cool. Neither acid or basis with a neutral pH. The pH changes if substances are dissolved in it. Good heat conductor, conducting easily than any other liquid. Uniform vertical temperature profile for large bodies of water is due t he easy heat conduction. With a temperature range of 0 to 100 ° Celsius, allows the water molecule to exist in most places around the world. Being able to dissolve many different compounds and chemicals as its an universal solvent with a high surface tension. Adhesive, elastic and in aggregate drops is what water tends to be. Despite the downward of gravity the phenomenon causes water to stick to the sides of vertical structures. It also allows waves and water droplet formation and for plants to move water dissolving nutrients from their roots to their leaves. [Pidwirny, M. 2006.] A group of living organism with some 300, 000 different species characterised by their green colour, are plants. Trees, herbs, flowers and ferns are some common groups of plants. Sprout, seedling is the meaning of planta a Latin word in which plant originated form. [R, Conan-Davies. 2009] Each part of the plant plays a different role. Absorbing from the soil, water and minerals are the roots which act like straws. Extra food for the future is stored and helps anchor the plant, the tiny root hairs assist in the nutrients absorption. Acting like the plumbing system for the plant and supporting it, is the stem. In the form of glucose water and nutrients is conducted from the leaves to different parts of the plant. Being either herbaceous and bendable or woody. The small stalk which attaches the leaf to the plants stem is called the petiole. The leaves are where majority of the plants food is made, through the process of photosynthesis. The leaves are designed to capture sunlight for the photosynthesis process to work. The reproductive section of the plant is the flower. Pollen and ovules are contained in the flower, after the pollen fertilizes the ovule through pollination, fruit develops. Providing seed covering is the fruits role and is also edible to humans and animals. The seed is the basis of a plant. [Botanical Garden, 2009] Carbon fixation and photosynthesis conducted by plans and algae is the energy and organic material source in all habitats. The earths 20% composition is changed radically by the plants process. Internal energy which relies on oxygen to move and grow is aerobic organism such as animals. The nutrients of animal and humans rely heavily on plants. [R, Conan-Davies. 2009] Petunia is scientifically known as; Petunia x hybrida. [NC State University, 2010] popular low lying annuals provide a brilliant display and attractive colours and green foliage in garden beds or containers. Blooming all summer long. Growing best in full sunlight with soil the is peat based which contains vermiculite. Petunias will survive in the shade that at least 6 hours of full sunlight daily. With ranging colours from whites to yellows, petunias can be the main attraction in a garden bed with minimal maintenance. There are several varieties of petunias. Water the plants pior to planting them and allow for drainage. Fertilising with a liquid fertiliser or soluble on every two weeks will help keep plants healthy. [Garden Guides, 2010 information peg] Calendula officinalis is commonly known as the marigold. [Eco India, 2008] Easy to grow and provide bright large displays in the garden. With a strong unpleasant scent, its effective for repelling garden pests. Coming in yellow, orange colours, can be planted in pots or gardens. Being able to be grown anywhere in all but cold climates. To help conserve moisture in the plants mulch and fertilise to keep them healthy. Regular water and will bloom throughout the summer and autumn and will keep pests away. [Garden Guides, 2010 information peg] The largest component of plants is water. 80 to 90% of water is the growing tissue part of the plant, lower water percentage parts are the woody, between 45 and 60% by weight of the water. Transporting minerals acting as a solvent and carbohydrates dissolved. Excellent solvent due to its unique chemical properties. A reactant in many chemical reactions throughout the plant. Oxygen we breathe everyday is the result of water acting as electron in the reaction of photosynthesis. Maintaining pressure in the plant so the leaves are literally inflated is an important role of water, as wilted plants is a lack of water. The water pressure is necessary for cell enlargement, growth and maintenance. [John Peterson, 2010] The net movement of atoms or ions of a higher concentration to a lower is diffusion. Until a state of equilibrium, diffusion will continue. Temperature, molecule density are the affect in which diffusions rate is, occurring through the stomata into the atmosphere. Through a sem i permeable membrane, the diffusion of molecules. Pressure can prevent osmosis. The minimum pressure required for the fluid to be prevented from moving due to osmosis is call osmotic potential. Until the osmotic potential is balance fluid will enter the cell via it. To help keep the plant cell turgor, any water gained by osmosis is kept. As a result of water entering the cells vacuole developing against the wall is turgor pressure. The water potential is made up by the pressure potential combined with the osmotic potential. Water will move from the cell with higher water potential to the cell with lower water potential if there next to each other. Water moves due to the soils higher water potential than the roots and plant parts. The plant will die if there is no net movement in the plants. The loss of water via osmosis is plasmolysis and the shrinkage of protoplasm. If the cell is placed in fresh water this process can be reversed, as the cell is allowed to regain turgor pressure. Permanent damage can occur to the cell. Alive or dead tissue, swelling is imbition. It can swell to several times their original volume. Minerals, cellulose and starches in suspension, attraction highly polar molecules is due to this. The initial germination of the seeds is this swelling process. Movement energy of substances is active transport. Enzymes and a pump in the plasma membrane are required for this process. ATP molecules energize the face. [Biology online, 2010] Transpiration is where 90% of water that enters the plant is loss. Through the leaves is the loss of water vapour, this is transpiration. Loss if water through the cuticle is less than 5%. Not just for the pressure reason, vital to plant life is water and the cellular activities that occur in water molecules presence. The internal plants temperature is regulated by water. From the smallest root all the way up to the smallest leaf is the xylem pathway, internal plumbing system paired with phloem. The plants water needs and resources are maintained in the nutrient transportation system or internal plumbing. Columns of water in the plant form as the water molecules adhere to the xylem and tracheids walls and vessels to cohere each other allowing an overall tension. Water that enters the roots via osmosis, water content from the soil travels up these columns. Enough force to transport water through the plant is the water potentials of the soil and the stomata, from bottom to top. Externa l input is the minerals in the soil, affects the growth rate and quality. Hydrogen, carbon, nitrogen, potassium, iron, calcium, cobalt, zinc, sulphur, sodium, manganese, chlorine, oxygen, phosphorus, molybdenum and boron are essential mineral in the plants growth. Minerals vary from plant to plant in which helps them to survive. If the soil is lacking these nutrients and fertilizer isnt used to compensated, the plant will demonstrate mineral deficiencies symptoms. The ratio of nitrogen, potassium and phosphorus compensate the deficiencies. [Biology online, 2010] 2.0 Hypothesis Microwave radiation water will affect the plants growth. Boiled water will have minimal impact on the plants growth. 3.0 Aim To investigate the effect of microwave and boiled water on plants. 4.0 Materials Used Gardening spade 4 black P.E.T pots Searles real premium potting mix Microwave Oven Boiling jug/kettle 2 petunia x hybrid 2 Calendula officinalis Pen and Paper Ruler Gloves 2 measuring jugs 5.0 Method Potting Plants: Group names and plant type experiment were labelled on the pot. Pot was half filled with potting mixed. Plant was removed from seedling tray. Roots of the plant were spread out. Plant was placed into the pot. Pot was then filled with soil surrounding the plant and compacted. Steps 1 to 7 were repeated for each plant. Measuring Plants: Plant height was measured from the base to the highest point and recorded. Number of flowers and buds on the plant were counted and recorded. Stems of the plant were counted and recorded. Heating Water: Measuring jugs were labelled, boiling water and microwave water. Kettle was filled with tap water and boiled. Glass proof jug was filled with tap water. Jug was placed in microwave for approximately 2 to 5 minutes on high. Water was left to cool. 500ml of both boiled and microwave water were measured out. 1 of both the boiled and microwave experiment plants was watered. Steps 6 and 7 were repeated for the remaining 2 plants. Each week the method of heating the water measuring were carried out recording the plants development and growth. 6.0 Discussion The results of the experiment showed the aims outcome. Two plants Calendula officinalis and petunia x hybrid were tested for the affect that boiling water or microwaving it had up it. The stimulus was that microwaving water altered the DNA affecting plants. The water travel up the transport system of the plants, known as the xylem like a circulatory system. This is how the water and the dissolved nutrients throughout it is dispersed throughout the plant. If microwaving water alters its DNA and affects the nutrients which dissolve itself from the soil, the reason it affects the whole plant is due to its transport system. The plants werent affected that much by the two different waters, although the microwave marigold wilted and died. However there shouldnt be much difference between the boiled and microwave water. The hypothesis was based upon the stimulus of the experiment stating, microwave radiation water will affect the plants growth. Boiled water will have minimal impact on the plants growth. Although the results didnt support the hypothesis, as there wasnt any major difference between the boiled and microwave petunias and marigolds. Although the microwave marigold welted in our experiment other groups may have had boiled plants that welted. The variables would have been the reason as to why we received the results we did. As there was no fertiliser added to the plants and some of them demonstrated the characteristics of lacking nutrients, as fertiliser can assist in this and supply the plant with the nutrients to help its deterioration the plants werent helped. The dying plant couldve have been easily prevented if a substitute nutrient like fertiliser was given to it. Many errors throughout the experiment can be improved. When potting the plants the soil could have been compacted more so there were no air pockets and the water soaked in more. It also wouldve prevented the plants to die. Measuring the data, could have been more accurate by having more than 3 standard measurements, things such as the plants width could have been measured and the plants weight. The standard error ranges which mean the way in which every group maintained their plant was different and play a major affect on them. Such as accidently pouring the wrong water into the incorrect plant would have affected the outcome even though there shouldnt be much of a difference between microwave and boiled water. The environment in which the plants were in also affected them as they were open and exposed to rain and bad weathers. Many things of the experiment could have been improved to get a more accurate result. 7.0 Conclusion The hypothesis wasnt supported nor was it wrong as there wasnt a massive difference between the microwave water and boiled water results, it seems that the microwave water plants were growing better than the boiled plants, although only by a minimal amount. The results can lead to further experimentation upon humans and wether microwaving makes us susceptible to cancers and harmful diseases. Tests on animals and if over a period of time that microwave radiation can affect you and deteriorate the body. Does microwave radiation alter foods DNA and prevent our bodies from registering it. The experiment has answered the hypothesis and reached the aim, it has also left many further possible investigations about microwave radiation and its affects. 8.0  Acknowledgements I would like to acknowledge the year 10 biology class, Mr. Fesuk the teacher, Ms. Mason student teacher and my group buddies; Caitlin, Dorine and Shadae.

Gallipoli :: essays research papers

Gallipoli Gallipoli, a favorite war movie of mine, is an Australian movie of the fateful First World War battle of Gallipoli. Directed and co-written by the talented Australian native Peter Weir; Gallipoli is a wonderfully written drama about two best friends, Archy Hamilton and Frank Dunne, who put aside their hopes and dreams when they join the war effort. The first half of the film is devoted to their lives and their strong friendship. The second half details the doomed war efforts of the Aussies, who are no match for the powerful and aggressive Turkish army.   Ã‚  Ã‚  Ã‚  Ã‚  The story begins in Australia during the early stages of the War in 1915 where two young men become friends and decide to enlist together. They pursue their goal, go through training in Egypt, and wind up in Turkey at Gallipoli, one of the early and important engagements of the conflict. The first main character is country boy rancher named Archy Hamilton played by Mark Lee, who is being trained by his uncle as a world-class runner, but Archy who dreams of romance and excitement is eager to run away from the center of nowhere and become a soldier.   Ã‚  Ã‚  Ã‚  Ã‚  Archy meets the city kid Frank Dunne, who is played by Mel Gibson, when he beats him in a track meet. Archy convinces Frank of the advantages of enlisting for God and and the country, and they decide upon joining the Light Horse Cavalry. The only trouble is that Archy is not old enough to enlist and Frank can't ride a horse. Overcoming these obstacles, Archy finally signs up against the wishes of his family. The second half of the film recounts their exploits just before and during the fateful battle of Gallipoli. In Egypt, Frank and his friends are camped near the Pyramids and spend their free time in the city of Cairo, drinking, getting ripped off by merchants and visiting brothels. During a chaotic training exercise, Frank and Archy meet once again and Frank is able to transfer to the light horse because they are now being sent to the Gallipoli peninsula as infantry and not have to ride the horses. Frank and Archy arrived at Anzac Cove and endure the hardship and boredom of trench warfare that went on for much of the campaign. Frank's infantry friends fought in the evening battle of Lone Pine, which was talked about but not shown.
