...whom. An example of a food chain that is part of the ecosystem would be how a hawk eats lizard, scorpion, tarantula, and insects. “Many animals get their energy by eating plants, but desert plants give up the fruit of their production very reluctantly. Sharp spines and chemical-laden leaves discourage plant-eaters….. Many are small and look like grains of sand. With sensitive front paws a kangaroo rat sifts sand to find seeds by touch eats them and transforms them into animal tissue.” -Desert Ecosystem. (n.d). Retrieved from http://digital-desert.com/joshua-tree-national-park/ecosystems.html For centuries, humans have affected biogeochemical cycles in many different ecosystems. Some of the impacts we have made on them are within the carbon, nitrogen, and phosphorus cycle. A desert like the Mohave Desert is affected from carbon cycles like when people are driving at 75mphs and they surprise a helpless creature that is trying to cross a highway and gets struck by a speeding car. The dead creature on the side of the road releases large quantities of carbon dioxide that eventually ties up biological tissues and is released again into the atmosphere. When the animal dies its tissues decay. Another...

...Tatiana Tikhomirova Marcio Pre-Degree I 3 March 2014 Life Cycle of a Frog Despite the fact that the frog is a small animal, in terms of symbolism, it is of some interest. In ancient Egypt, because of its fertility, as well as a striking transformation from egg to a tadpole, and then in the quadruped animal, the frog was considered strange creature and was a symbol of emerging and ever-renewing life. Often, the ancient gods of care arising out of the mire, depicted with frog heads. Goddess of child-birth, who was a good helper of the popular religion, looked like a frog. (“Heqet”) This essay will describe frog’s transformation from egg to adult frog by three steps. First of all, frogs lay eggs. When multiple eggs stick together, they are collectively known as frogspawn. After fertilization, the innermost portion liquefies to allow free movement of the developing embryo. Most eggs are black or dark brown, and it has the advantage of absorbing heat from the sun, which holds the insulating capsule. Frogs lay a lot of eggs because there are many dangers between fertilization and grown frog. Those eggs that die turn white. Life starts right as the central yolk splits in two. It then divides into four, then eight, etc. Soon, the embryo starts to look more and more like a tadpole, getting longer and moving in egg. Usually, about 6-21 days after being fertilized, the egg will hatch. Most eggs are found in calm or static waters. When the rain comes along, after development of 7 to 9 ...

...trees, birds, water, microorganisms, soil, and people. Lake Mead National Recreation Area (NRA) located in Nevada provides spectacular scenic vistas of Lake Mead and rugged and isolated backcountry. Amazing and drastic physical features include deep canyons, colorful soils, sheer cliffs, distant mountain ranges, dry washes, the lakes, and rock formations and mosaics of different vegetation (National Park Service, 2012). In this essay I will be discussing the major structural and functional dynamics of Lake Mead National Recreation Area (NRA) on Roger Spring and Black Canyon Springs and how the human being have affected this ecosystem by interacting with its biogeochemical cycles. I will show how knowing the ecosystem structure and function could help in its management and restoration of the ecosystems as well. Black Canyon Spring is located downstream of Hoover Dam. Here, we can find springs of both the thermal (hot) and non-thermal (cold) variety with water temperatures ranging from about 55° to 136° Fahrenheit. Rogers Spring is located on “North Shore Complex” of the Lake Mead National Recreation Area. This area comprises of the terminal discharge areas for the regional carbonate-rock aquifer system from eastern Nevada (National Park Service, 2012). Chapin and colleagues (1996) recently extended this framework to develop a set of ecological principles concerning ecosystem sustainability. They defined “...a sustainable ecosystem as one that, over the normal cycle of disturbance...

You will also learn the carbon and nitrogen cycles. Last but not least you will learn about natural and anthropogenic disturbances and how to recover them. There will also be examples of each. THE DESERT The desert can be one of the most beautiful places to visit. It also can be one of the hottest places every. The desert Al Kharj is in Saudi Arabia. Al Kharj is in the middle of Saudi Arabia. Al Kharj has a lot of small towns. Location The ecosystem the desert can be found in many places. One example were you can see the desert is Al Kharj, Saudi Arabia. I still remember the day that I stepped off the airplane. The desert has its surprising moments. One of them is when it is cold it is very cold. Abiotic and Biotic Components1 The abiotic components of the desert are non-living. The desert abiotic components are sand, sunlight, water, air, and temperature to name a few. When I was in Al Kharj, there were a couple of sand storms. The sand storms actually hurt. We were not allowed to drink the water over there. The temperature was over 100 degrees every day. The sunsets and sun raises were beautiful. The biotic components of the desert are all living things. The desert biotic components are scorpions, coyotes, snakes, spiders, and cacti to name a few. I saw a dead scorpion...

...Running Head: Essay Paper Fruit & Seeds nita brown Strayer University Mr. Kenneth Jones May 28, 2010 1 Why are some fruits sweet and some sour, whereas others have no specific taste? Each fruit has its own distinct taste, which will differ in some way form the taste of any other fruit. Fruits having more of fructose taste sweeter, while those having more acids taste sour. There are many fruits, which almost equal quantities of fructose and acids. In general raw fruits contain more acids but on ripening, the quantity of acid in them decrease and the amount of sugar increase. Fruits contain fructose, certain acids, vitamins, starch, proteins and cellulose. Fruits that are sweet are, watermelon, guavas, and apples. The fruits that are sour are, lemon, raw mango, and limes. How does the ripening of a fruit affect the process of seed dispersal? Fruit development and ripening are very unique to plants. They represent an important component of human and animal’s diets. Analyses of fruit –ripening mutants and ripening –related gene expression suggest higher levels of a development that remains to be defined. A fruit not only protects the seeds inside it, but also may aid in dispersing those seeds away from the parent plant. The dispersal of seeds is important because it reduces competition for sunlight, soil, and water between the parent plants. The role of sunlight signaling in fruit carotenoid may be examined...

...We hear the term “greenhouse gas” a lot—but what is it? Humans add various gases to the earth’s atmosphere every day; these gases (known as “greenhouse gases”) consist primarily of carbon dioxide, ozone, chlorofluorocarbons, nitrous oxide, and methane, and tend to warm the earth. Trees help counter greenhouse gas production during photosynthesis, by taking in carbon dioxide as waste material and producing oxygen, which of course we all need to survive. Scientists predict that the daily addition of greenhouse gases to the atmosphere, combined with daily removal of large portions of the world’s forests, will raise the earth’s average temperature by several degrees in the next century. This in turn will raise the level of the sea and potentially create significant changes in weather patterns on a global scale. As we move into the future, many climatologists expect that most of the United States will warm. What we do not know yet is how to scientifically predict which parts of the nation will become wetter or drier. We do know there is likely to be an overall trend toward increased precipitation and evaporation, and more intense weather systems, in the form of violent rainstorms, blizzards and sun-baked, drier soils. The Facts—What Do We Already Know About Changing Global Conditions (Global Warming)? Global temperatures are rising. Observations collected over the last century suggest that the average land surface temperature has risen 0.45-0.6°C (0.8-1.0°F) in the last...

...service improvement initiative. The change I propose was to introduce different colour lids for the water jugs to indicate fresh water is being provided twice a day in the ward where I was under going my recent placement. This ward caters “step down” patients who are initially admitted to cardiac care unite, thus involvement of multidisciplinary team and interprofessional working is essential. The paper ‘Making a Difference’ Department of Health (1999) suggests that ‘effective care is the product of interprofessional working. Professionals working in collaboration provide care which is designed to meet the needs of the patient’ I shall use a model of reflection in order to describe the proposed change I have suggested. Reid (1993) suggests ‘that reflective practice is potentially is both, a way of learning and a mode of survival and development once formal education ceases’. I have chosen Gibbs model (1988) of reflection as it incorporates the following: description, feelings, evaluation, analysis, conclusion and an action plan thus Gibbs’ reflective cycle encourages me to think systematically about the phases of an experience and therefore I shall use all the headings to structure my reflection. Discussion under the sub-heading ‘analysis’ will include the process involved in proposing the change in the light of the PDSA cycle (see Appendix 2 ). A conclusion to the essay will then be given which will discuss the knowledge underpinning the reason for the change. I have...

...coined by ancient and medieval scholars. Such scholars included Herodotus, (485-425BC) and Aristotle (382 – 322 BC). Each of these philosophers had reported their own findings regarding diverse geomorphological phenomena. Although the scholars might have agreed on various aspects, there was immense criticism; thus the divergent claims. In this essay, I will briefly compare and contrast Herodotus’ and Aristotle’s arguments in some of the ideas that led to the development of modern geomorphology. River Siltation Both Herodotus and Aristotle present arguments in regards to river siltation. Herodotus first notes that there were yearly increments silt and clay deposits in the Nile River on its flood plains. He explains that the Nile River floods every year, and in the process, it irrigates the flood plain along either bank and deposits fresh silt along its banks. He noted that the Nile has three distinct regions (Rennell, 2011).. He further explained that flood waters from the White Nile flow through an enormous marsh called the "Sudd" in the southern part of the modern country of Sudan, and arrive later and more slowly than the flood waters from the Blue Nile and the Atbara River. This contribution was crucial in determining the modern day irrigation along the Nile as well as determining where people could live. Aristotle had not visited Egypt himself, but he had at hand excellent observations in the works of Herodotus who had visited there in 450 BC, and perhaps reports of...

...“Consider the Lobster” Summary 08/26/2013 David Foster Wallace’s essay “Consider the Lobster” examines the pain that Lobsters feel when they are being boiled alive to be consumed by Humans. He uses the lobster as an example to expand his examination, bringing out the relationship between humans and the animals that we consume. Wallace starts of his essay by mentioning the Maine Lobster Festival and its huge crowd of over 80,000 people that consume over 25,000 pounds of lobster during the 5 days that the festival lasts. He starts off the essay with admiration in his tone as he describes the Maine Lobster Festival to his readers. After he’s done praising the festival, Wallace reveals that his main intention of writing the essay was to question if killing animals is morally acceptable. He explains that Lobsters have nociceptors, invertebrate versions of the prostaglandins and major neurotransmitters that enable human beings to record pain. Lobsters, however, do not appear to be able to absorb natural opioids like endorphins and enkephalins which are what advanced nervous systems use to deal with pain. Wallace examines this information about lobsters and recognizes that lobster either suffer more than a human would because they can’t control pain as well as humans can or they simply can’t comprehend the idea of pain. Wallace sympathizes that if lobsters can’t control their pain, then humans are unnecessarily boiling and eating them, as a result, putting them through immense...

...In this essay I will be explaining “what is hypnosis” by looking through various literature sources, internet sources and by using my own knowledge, I will include a brief history of hypnosis to aid this. I will then go on to describe the psychological and physical aspects of hypnosis, followed by discussing the role of relaxation in hypnotherapy. Hypnosis is a state of mind achieved using a set of techniques. The hypnotic state is natural for all human beings. Hypnosis enhances an individual’s concentration which increases their responsiveness to suggestion; this is due to when being in a hypnotic state the subconscious is the one that is more responsive to suggestion than when you are in a fully conscious state. The suggestion will travel directly to the subconscious where it will help the individual to make the necessary changes in their thought patterns, behaviours or physiological state. The history of hypnosis goes back as far as ancient Egypt, Australian aborigines, North American Indians and Hindu cultures; history indicates that every culture has used hypnosis in one form or another (Chrysalis 2010). In the 1700’s, an Austrian doctor called Franz Anton Mesmer recognised ancient healing techniques and used them in his theories. These theories included animal magnetism and a belief that cosmic fluid could be stored in inanimate objects such as magnets, and transferred to patients to cue them of any illness...
