Plants and Life on Earth Essay

Plants are the only organisms that can convert light energy from the sun into food. And plants produce all  of the food that animals, including people, eat. Even meat. The animals that give us meat, such as chickens and cows, eat grass, oats, corn, or some other plants. Plants make oxygen One of the materials that plants produce as they make food is oxygen gas. This oxygen gas, which is an important part of the air, is the gas that plants and animals must have in order to stay alive. When people breathe, it is the oxygen that we take out of the air to keep our cells and bodies alive. All of the oxygen available for living organisms comes from plants. Plants provide habitats for animals Plants are the primary habitat for thousands of other organisms. Animals live in, on, or under plants. Plants provide shelter and safety for animals. Plants also provide a place for animals to find other food. As a habitat, plants alter the climate. On a small scale, plants provide shade, help moderate the temperature, and protect animals from the wind. On a larger scale, such as in tropical rainforests, plants actually change the rainfall patterns over large areas of the earth’s surface. Plants help make and preserve soil In the forest and the prairie, the roots of plants help hold the soil together. This reduces erosion and helps conserve the soil. Plants also help make soil. Soil is made up of lots of particles of rocks which are broken down into very small pieces. When plants die, their decomposed remains are added to the soil. This helps to make the soil rich with nutrients. Plants provide useful products for people Many plants are important sources of products that people use, including food, fibers (for cloth), and medicines. Plants also help provide some of our energy needs. In some parts of the world, wood is the primary fuel used by people to cook their meals and heat their homes. Many of the other types of fuel we use today, such as coal, natural gas, and gasoline, were made from plants that lived millions of years ago. Plants beautify Plants, because of their beauty, are important elements of out human world. When we build houses and other buildings, we never think the job is done until we have planted trees, shrubs, and flowers to make what we have built much nicer.

Chinas Population Problem essays

China's Population Problem essays The Chinese government has taken the enforcement of family planning and birthrate laws to an extreme by violating the civil rights of its citizens, which has had bad effects on the morale of its people (Whyte 161). China's population has grown to such an enormous size that it has become a problem to both the people and government. China, the most populous country in the world, has an estimated population of about one thousand-one hundred-thirty three point six million (Hsu 1). Ninety-four percent of the population thrives in the eastern half of China, which composes about forty-three percent of China's total area (Hsu 1). The eastern half of China contains its most populous cities like Beijing, Shanghai, and Tianjin. However these cities have a low fertility rate due to recent bandwagons of birth control. The average density in the eastern half of China averages around two-hundred and thirty-six people per square kilometer, whereas the density in the west half averages around ten poi nt six people per square kilometer (Hsu 1). Current enforcement of Chinese laws prevents migration between provinces without proper authorization, as the citizens in the west half of China have a desire to live in a more urban life where jobs can be found easier, and the citizens in the more populous eastern half have a stronger desire to live in the more rural western China (Hsu 4). The Chinese have always had a large population (Hsu 1). Even in ancient times where the population would never fall below sixty million (Hsu 1). Later, in the eighteenth century the population rose exceedingly and China became the strongest and most economically wealthy (Hsu 1). By the time the Qing Dynasty ruled, the fertile people of China had reached a population of three-hundred million (Hsu 1). The birthrate in China did decline in the nineteen-fifties due to campaigning by the government on birth control (Hsu 1). However, after the population decreased the government t...

Comedy Club essays

Comedy Club essays The Comedy Club was a presentation by Steve Kent in which it dealt with comedy as a mean of medicine. He called it the medicine of the soul. Researches suggest that comedy raises the immunes level of T cells. This in its self is a scientific phenomenon in which research is being gathered to try to explain why this is taken place physiologically. During his presentation, Steve talks about the power of humor in which he states it both gets you into trouble and out of trouble. For example, when someone falls to the ground they often use humor to avoid as much embarrassment as possible. It is in a sense your bodys protection tool from emotion. He also dealt with the use of humor to lighten the seriousness of situations. Studies support that people who laugh a lot while diagnosed with a terminal illness, they are more likely to live longer then people who laugh less (personal I have no idea how this was researched). I feel that humor is of great importance. If the world was without humor, I think that it would be an unbearable place to live in. The problem is that not everyone has as much to laugh at. That is why it is important for people like Steve to travel and teach people what comedy is all about (of course he does this in a humorous way). During his performance, he used the audience as his props and his story line. This was one way which he got the audience involved and demonstrated the meaning of improv. He was incredibly funny and he did achieve is directive by doing two things: 1. Teaching us about the effect that humor has; 2. He made us laugh. I would recommend Steves seminar on humor to anyone interested in learning more about the nature of the body and the delighting of the soul. ...

Four Criteria for Identifying a Rock

Four Criteria for Identifying a Rock What is a rock, exactly? After some thought and discussion, most people will agree that rocks are more or less hard solids, of natural origin and made of minerals. But to geologists, all of those criteria have exceptions. Are All Rocks Hard? Not necessarily. Some common rocks can be scratched with your fingernails such as shale, soapstone, gypsum rock, and peat. Others may be soft in the ground, but they harden once they spend time in the air (and vice versa). And there is an imperceptible gradation between consolidated rocks and unconsolidated sediments. Indeed, geologists name and map many formations that dont consist of rock at all. This is why geologists refer to work with igneous and metamorphic rocks as hard-rock geology, opposed to sedimentary petrology. Are All Rocks Solid? Some rocks are far from completely solid. Many rocks include water in their pore spaces. Many geodes   hollow objects found in limestone country hold water inside them like coconuts. Two rocks that are barely solids include fine lava threads known as  Peles hair  and the fine open meshwork of exploded lava reticulite. Then theres the matter of temperature. Mercury is a liquid metal at room temperature (and down to -40 F), and petroleum is a fluid unless its asphalt erupted into cold ocean water. And good old ice meets all the criteria of rock-hood too...in permafrost and in glaciers. Are All Rocks Natural? Not entirely. The longer humans stay on this planet, the more that concrete accumulates. Concrete is a mixture of sand and pebbles (aggregate) and a mineral glue (cement) of calcium silicate compounds. It is a synthetic conglomerate, and it acts just like the natural rock, turning up in riverbeds and on beaches. Some of it has entered the rock cycle to be discovered by future geologists. Brick, too, is an artificial rock in this case, an artificial form of massive slate. Another human product that closely resembles rock is slag, the byproduct of metal smelting. Slag is a complex mixture of oxides that has many uses including road-building and concrete aggregate. It has found its way into sedimentary rocks already. Are All Rocks Made of Minerals? Many are not. Minerals are inorganic compounds with chemical formulas and mineral names such as quartz or pyrite. Coal is made of organic material, not minerals. The various types of stuff in coal are instead called macerals. Similarly, what about coquina...a rock made entirely of seashells? Shells are made of mineral matter, but they arent minerals any more than teeth are. Finally, we have the exception of obsidian. Obsidian is a rock glass, in which little or none of its material has gathered into crystals. It is an undifferentiated mass of geological material, rather like slag but not as colorful. While obsidian has no minerals in it per se, it is unquestionably a rock.

Reflective Report includee 2 tasks M Essay Example | Topics and Well Written Essays - 1750 words - 1

Reflective Report includee 2 tasks M - Essay Example I also expected to combine work and study in order to finance my personal needs, acquire valuable work experience as well as improve my professional network. I have learned how to live in a multicultural environment since I came to the UK even though there were a lot of challenges in adapting to the life in UK. I have also become a more sociable and confident person from interacting with individuals from diverse backgrounds. I have been exposed to different experiences and cultures of which I wouldn’t have if I was not in the UK. Before I came to the UK I was very shy unlike now. It was not easy for me to make major decision all by myself but the experience here has made me more independent. Among the things I have learnt at Greenwich is how to combine both the theoretical and practical aspects of my studies in real life situations. This has been very helpful to me since theory doesn’t always aid one in getting a placement, an internship or a job. Given that English is not my first language, communication proved quite an uphill task for me at first but I eventually had to learn how to use it fluently. I have learnt to improve my English by wide range of educative books such as those which target international student learning English. This was very useful in the beginning since English in such books is written in a manner that is somewhat simplified. This made it easy for me to learn and understand English. I also sharpened my skills by frequently watching English TV episodes. This made learning more fun. I also engaged in discussions with my fellow student. This improved my communication skills since I can now confidently express myself in English. Since I started learning at the Greenwich University, my study skills have greatly improved. I have learnt to always prepare for my classes at the most appropriate time. For classes that involve recitation, I spend time making questions regarding previous recitation, brushing up on the

Nursing Practice Act Requirements Essay Example | Topics and Well Written Essays - 250 words

Nursing Practice Act Requirements - Essay Example On joining the profession, Nurses should perform their duties with due diligence and care. Every action of a nurse should point to the well being of a patient. For instance, a nurse may deceive patients about improvement of their health to avoid unnecessary fear.A code of ethics guides the nurses to act professionally, honestly, and with integrity. This calls for a nurse to be knowledgeable of their work, compassionate, flexible, patient centred, have people skills, and think critically. Unlike in the nursing profession where every nurse owes a duty of care to patients entrusted to them, celebrities do not owe a duty of care to their fans. They give their views in songs, poems, and speeches and expect their fans to make good judgements and pick what concerns them. Most of celebrity’s profession have no code of ethics and thus they operate on good morals.In conclusion, even after due care is taken in selecting persons to join nursing profession where proper education is given, some nurses still practise in the dark side.
