Mitosis Quiz on Mitotic Cell Division

Mitosis Quiz on Mitotic Cell Division Mitosis Quiz This mitosis quiz is designed to test your knowledge of mitotic cell division. Cell division is a process that enables organisms to grow and reproduce. Dividing cells go through an ordered series of events called the cell cycle. Mitosis is a phase of the cell cycle in which the genetic material from a parent cell is divided equally between two daughter cells. Before a dividing cell enters mitosis it goes through a growth period called interphase. In this phase, the cell duplicates its genetic material and increases its organelles and cytoplasm. Next, the cell enters the mitotic phase. Through a sequence of steps, chromosomes are equally distributed to two daughter cells. Mitosis Stages Mitosis consists of several stages: prophase, metaphase, anaphase, and telophase. Finally, the dividing cell goes through cytokinesis (dividing of the cytoplasm) and two daughter cells are formed. Somatic cells, cells of the body other than sex cells, are reproduced by mitosis. These cells are diploid and contain two sets of chromosomes. Sex cells reproduce by a similar process called meiosis. These cells are haploid and contain one set of chromosomes. Do you know the phase of the cell cycle in which a cell spends 90 percent of its time? Test your knowledge of mitosis.

Waste to Energy Technology Research Paper Example | Topics and Well Written Essays - 1000 words

Waste to Energy Technology - Research Paper Example Undoubtedly, the waste to energy technology will address the waste disposal issues as well as the growing energy needs of the world. Waste to Energy Technology Waste to energy, or interchangeably energy from waste, can be referred to the process of generating energy in the form of heat or electricity through the incineration of waste materials. Incineration is â€Å"the process of reducing combustible waste to inert residues by high temperature combustion† (Lettsome, 2008, p.191). However, many countries have set strict emission standards for this process as many traditional WtE plants released huge amounts of sulphur dioxide, nitrogen oxides, and dioxins. Modern incineration plants are eco-friendly and they release little toxic gases or other pollutants. As Ramboll (2006) points out, modern incinerators are capable of reducing the original waste volume by 95 to 96 percent depending on the type of waste material under incineration. The use of incineration technique for the con version of municipal solid waste to energy is a conventional application of waste to energy technology. In the incineration process, generally an RDF is burned to boil water and thereby power stream generators for the purpose of generating electricity for home and business use. However, the method of incineration of municipal solid waste for the generation of electrical energy was widely criticized since this process has been damaging the environment by causing acid rain. In response to this environmental concern, companies used technologies like lime scrubbers on smokestacks. The modern incineration plants are eco-friendly, because â€Å"many times more dioxin is now released from home fireplaces and backyard barbecues than from incineration† (Rosenthal, 2010). Today, a number of new and improved technologies have been developed to produce energy from waste materials without combusting them directly. Majority of such technologies can generate more amount of electric power fr om the same volume of waste materials than through direct combustion method. As described in Bio Earth (2009), in new waste to energy technologies, corrosive components are separated from the converted fuels and therefore, this process contributes to higher combustion temperatures in internal combustion engines and boilers. Hence, they are more productive than conventional WtE plants. Some of those technologies have the potential to convert energy into liquid or gaseous fuels. As reported in World News Inc (2012), gasification, thermal depolymerization, Pyrolysis, Plasma arc gasification PGP are some of the thermal WtE technologies whereas anaerobic digestion, fermentation, mechanical biological treatment are non-thermal technologies. The popularity of waste to energy technologies has considerably increased over the last decade. During this period, industrially important countries like China and Japan built a number of WtE plants in order promote their national productivity. Global Group Consulting Services LLC operates across America and Caribbean in order to promote the application of potential waste to energy technologies and to resolve Municipal Solid Waste issues in small to mid-size cities. As Herndon (2011) reports, Fulcrum BioEnergy, Inc has been scheduled to commence the operations of its new $180 million WTE plant in 2010; and the project designers forecast that the plant may produce

Investment Enhancement Paper Research Example | Topics and Well Written Essays - 1000 words

Investment Enhancement - Research Paper Example This type of investment strategy might be attractive for a senior citizen investor who is looking to minimize or eliminate investment risks since he will be retiring within a few years and needs to lock in his retirement’s benefits. For the typical investor there is variety of benefits to utilizing international investments to improve financial portfolio performance On the other hand most investors are looking to maximize their return on investment therefore are willing to accept an increased level of risk in order to benefit from the possibility of much higher returns. Although studies have shown that the benefits of direct international investments to achieve adequate international portfolio diversification are limited for U.S. investors partly due to the fact that U.S. investors can invest in domestic multinational corporations, country funds. Another reason is possibly because the U.S. both the economy and its stock market are much more developed and diversified than other countries. The benefits of international investments are more easily realized in underdeveloped countries than in developed countries. Investing internationally makes sense to a lot of potential investors since for example foreign investment mutual funds provide the opportunity for individual investors which typically lack the necessary financial resources to buy a large number of stocks on their own to benefit from the expertise of a professionally administered international investment mutual fund. Recently national economies have become more closely linked due to globalization, growing international trade, and investment capital flows. This might lead to realize that the benefits of international portfolio diversification might be overstated. Despite significant interdependencies between markets, there is still room for international diversification. A recent tendency has been for investors to look into emerging economies as good candidates for international diversification. Sinc e ongoing research suggests that since emerging economies are not closely correlated to industrialized there are still considerable opportunities to benefit from international diversification. There are various investment vehicles investors can use to build up a portfolio in the equity and money markets. The most popular form of investment is common stock. The price ticker investors’ track on Wall Street represents common stock investments. Common stocks are equity investment that represents a right of ownership. People that invest in common stock have voting rights over certain corporation decisions. There are different types of common stocks. Two types of common stocks are blue chip and penny stocks. Blue chip stocks are stocks that are issued by a well-known company with an established record of making money and paying dividends (Teweles & Bradley & Teweles, 1992). An example of a blue chip stock company is Microsoft Corporation. Within the category of common stock blue ch ips are considered the safest type of investment. On the other side of the spectrum are penny stocks. Penny stocks are can be defined as stocks that trade at a relative low price and market capitalization typically outside the major marketplaces (Investopedia, 2011). Penny stocks are very risky and on many occasion the stocks go into default as these penny stock companies run out of business. Another popular type of investment that is often

Change for the better Essay Example for Free

Change for the better Essay Describe a situation in which critical and creative thought could have been used for a better outcome. Describe why it is important to think critically and creatively in similar situations. A situation that critical and creative thought could have been used for a better outcome is when buyers were making choices about buying real estate. There was a time back in 2006 thru 2007 that the real estate market was showing significant weakness where previously to that year it was thriving, but buyers were not thinking critically and creatively. Instead investors were being avaricious and they let their greedy ways of thinking make decisions for them. To make things poorer, lenders were very hostile in their lending procedures while nobody in the government was watching. Investors continue to buy properties at high prices. They were even paying over the listed prices for certain properties. Then there went it was ruined, and investors were trapped with nearly valueless properties. This is why and how thousands of properties started going into foreclosure. This was a hard lesson to learn but today the lending rules have changed thanks to a revamp of the lending practices. By thinking critically and creatively the government has constricted an improved unsupervised system. Define free will, truth, knowledge, and opinion. Explain how we use them to form thoughts. The moderate definition of free will is when people have choices when it comes to decisions like whether to attend an event or finish an assignment. Another example is getting up to go to work, although it may look uncontrollable, it really is a choice you make every day. For this reason, it is ironic that so much confusion exists about truth (Ruggiero, p. 27, 2009). Even otherwise intelligent people can be heard saying things such as â€Å"Everyone makes his or her own truth,† â€Å"One person’s truth is another person’s error,† â€Å"Truth is relative,† and â€Å"Truth is constantly changing† (Ruggiero, p. 27, 2009).All of these ideas undermine thinking (Ruggiero, p. 27, 2009). Knowledge can change as new information is becomes accessible. Ideas do not constitute knowledge unless they correspond to reality (Ruggiero, p.28, 2009). â€Å"Opinions are i ntensely personal, so it is understandable that people have strong feelings about theirs (Ruggiero, p. 34, 2009). But many people carry those feelings beyond the boundaries of good sense (Ruggiero, p. 34, 2009). They take the valid idea â€Å"Everyone has a right to his or her opinion† to the ridiculous extreme of â€Å"Everyone’s opinion is right† (Ruggiero, p. 34, 2009).

Battle of Conformity and Non-conformity Essay

In Tom Schulman’s Dead Poets Society a group of bright students are enrolled in a prestigious New England private school named Welton Academy. This school stresses conformity and tradition as one of its trademarks. In order to survive in this school one must never challenge the institution. Dead Poets Society is a powerful example of the constant battle between conformity and non-conformity. Mr. Keating, a teacher at Welton, fights on the side of non-conformity and free- thinking. On the first day of school, he shows them a picture of past classes. He tells them that they are all in the Earth now, and they have a message for his current students. The message was â€Å"carpe diem†, or â€Å"seize the day†. He is telling them that one-day they will be dead, so it is imperative that they â€Å"make their lives extraordinary† and to â€Å"carpe diem†, seize the day. Carpe diem is important because he tells them to follow their dreams, but in many cases their dreams went against the principles of the school. Through his unorthodox teaching style he taught them that conformity was not necessary. Many of the poems he taught them all preached carpe diem, such as the following: Gather ye rosebuds while ye may Old time is still a flying And this same flower that smiles today Tomorrow will be dying. â€Å"Gather ye rosebuds while ye may† means that make your dreams come true before you die. However, they could never live their dreams if they conformed to what their parents wanted, or what their principal wanted. Another example of how his teaching promoted free thinking and non-conformity was the way he ripped out the introduction by J. Evans Prichard. He didn’t want his students to conform to Prichard’s views on poetry he wanted them to form their own views. He called the introduction â€Å"excrement† and yelled â€Å"rip it, rip it out†. Everyday in his classroom there would be a lesson that preached against non-conformity along with poetry. After reading a poem, Mr. Keating stood up on the table and said, â€Å"Why do I stand here? To feel taller than you? I stand on my desk to remind myself that we must constantly force ourselves to look at things differently.† He then invites his students to stand up. This is obviously a lesson in free thinking and non-conformity. He is saying that there is more than one view to everything, and he is inviting them to be unconventional. Mr. Keating  helps almost all of his students become free thinkers and non-conformists. This is illustrated at the end, when they all stand on their desks. Mr. Nolan, the principal at Welton, is a man who believes that tradition and conformity should be upheld in all cases. From the first day of school, he teaches them never to diverge from tradition. In the opening assembly, every word spoken by the students is done in unison. They all recite the four pillars, which are tradition, honor, excellence, and discipline. Neil Perry is a victim of society’s need for conformity. He is a Welton student, who has been entrapped in his father’s web of restrictions.

The Benefits Of Non Renewable Energy Essay - 1832 Words

TOPIC 1 The term, â€Å"non-renewable energy,† is at its most basic form, means that the sources of energy will eventually one day run out and not replenish itself. Non-renewable energy comes in many forms. For example: coal, crude oil and natural gas. These sources are categorized as fossil fuels, meaning that they were formed in the past due to natural processes from dead organisms. Non-renewable energy has been proven to be very beneficial to the US, however, many people argue the negatives are not worth the benefits. These fossil fuels serve to be very beneficial for our use and need for energy. The accessibility of these energy sources are relatively abundant in our environment. These sources of energy, specifically crude oil for example, are found in abundance underground in certain areas. For example, while there is not huge oil sources underground everywhere, there are large rigs in certain areas of the world that supply an astronomical amount of crude oil for our use. Places such as Saudi Arabia and Canada have been the 2 largest providers of non-renewable oil for the US. Similarly, there are many places in the US that non-renewable resources like oil and coal have been tapped into. These oil rigs and coal mines are being used at a rate that some worry is not sustainable, or responsible. The oil rigs, in particular, produce a real economic boom as well as the benefit to fulfill our energy needs. For example, back when gasoline was 4 dollars a gallon, itShow MoreRelatedBenefits Of Non Renewable Energy788 Words   |  4 PagesNon-Renewable energy is the energy which is taken from the sources that are available on the earth in limited quantity and will vanish fifty-sixty years from now.
