bio lab 6 essays Microscopy and the Electron Microscope Humans have been magnifying objects for centuries by using lens. Using lens to magnify objects has helped mankind know more about the cell theory and ways of life. Zacharias constructed the first compound microscope. Robert Hooke used the microscope to examine slices of cork. He noticed many little boxes and called them cells. Cells are the building blocks of life. We would not know as much about cells as we do with out microscopes. It is important to know about the different types of microscopes and how they function. CD player, Individualized Biology lab book, pen, and your brain. Objectives: (See page 2 of Individualized Biology Unit 9 Script.) Anton van Leeuwenhoek is considered to be the father of bacteriology. He used a simple microscope consisting of one lens to observe bacteria and other unicellular microorganisms. He grinded the lens he used, so that the lens had great curvature. He reached magnifications of 270 diameters. This was the most reached from his time. Magnification increases the visibility of what ever detail the objective lens can reveal. There is a significant relationship between wave length and resolving power. Wavelength is the distance between corresponding points on two successive waves. The shorter the wave lengths are used, the greater the resolving power is. Two objects that are closer together than one half the wave length of light used can not be seen as separate objects. There are several ways to increase the resolving power. You can use a shorter wave length, project on to screens, use quartz lens, use ultraviolet light, or use an objective lens that can accept a greater cone of light. The wavelength that would give the best resolving power for a light microscope is blue. Light source has a great effect on a microscope. The bright fi ...

Also, the English and Spanish words for particular fruits may not always be an exact match, sometimes because two similar species of fruits may share a name. For example, what is known as un arndano in Spanish goes by several different names in English, such as huckleberry, bilberry, blueberry, and cranberry. One common source of confusion is that a limà ³n can refer to a lemon or a lime depending on the region. The names of many fruits are similar in English and Spanish, either because they have a common origin (such as from Latin) or because the English borrowed a fruit name from Spanish.The trees or other plants that produce sometimes have distinctive names related to the name of the fruit.Some fruits have names that are understood only in certain localities. Common Foods Made With Fruit apple cider - la sidra sin alcoholapple crisp, apple crumble - el crujiente de manzanaapple pie - el pastel de manzanacompote - la compotafruitcake - el pastel de frutafruit cocktail - el cà ³ctel de frutasfruit salad - la ensalada de frutassjam - la marmeladajuice - el jugo, el zumopeach cobbler - el pastel de durazno, tarta de duraznostrawberry sundae - el sundae de fresa, el helado con fresas Fruit Names English and Spanish Share English and Spanish share the names of various  fruits for one of two reasons. Either the English name came from Spanish, or English and Spanish gained the name from a common source. There are no fruits on this list in which the Spanish derived from English, although its likely that kiwi, a word from Maori, was adopted because of U.S. English influence. Here are etymologies of several Spanish-derived fruit names we use in English: papaya - Spanish picked up papaya from Arawak, an indigenous language of the West Indies, and it spread to English via the shipping industry.pear - The English name for the fruit comes from the Latin pera, which is also what its called in Spanish.plantain - Plantain has two meanings - a fruit similar to a banana and a type of flat-leaved weed. Both are called pltano in Spanish. The words with the first meaning probably came to us via Spanish, which picked up the word from the West Indies, while the word with the second meaning came indirectly from Greek.tomatillo - Tomatillo in Spanish is tomate with the diminutive suffix -illo. Other Spanish food words using this suffix include tortilla (omelette or tortilla, from torta, cake), mantequilla (butter, from manteca, lard or some types of butter), and bolillo (bread roll, related to bola, ball).tomato - At one time, the tomato was called a tomate in English, the same as its Spanish name. The Spanish in turn came from Nahuatl, an in digenous Mexican language, which used the word tomatl. The tl ending is very common noun ending in Nahuatl. Sources for some of the other fruit names include Italian (cantalupo and cantaloupe), Latin (pera and pear), and Arabic (naranja and orange). Words for Fruit-Producing Plants Although the words for tree and bush are rbol and arbusto, respectively, many of them that produce fruit have names related to the name of the fruit. Here are some of them: apple tree - el manzanoblackberry bush - la zarzacherry tree - el cerezograpevine - la vid, la parralemon tree - el limoneroorange tree - el naranjopear tree - el peraltomato vine - la rama de tomate

Global Versus Domestic only Mergers and Acquisitions Essay

Global Versus Domestic only Mergers and Acquisitions - Essay Example The strategy of Mergers and Acquisitions (M&A) plays an important role to both sides of the growth path by enabling strong companies to assume faster growth than their competition thereby rewarding entrepreneurs for their efforts and ensuring the weaker companies get swallowed faster and even made redundant through share erosion and exclusion. M&A, therefore, is a crucial fraction of any healthy economy by basically ensuring that shareholders are able to gain rewards from their businesses (Thomson & Martin, 2005). This fact, coalesced with the potential for large returns makes M&A a highly attractive method for entrepreneurs and business owners to capitalize on their company values. It is, therefore, no wonder that the unique business trend of M&A has, in the recent times, become a common occurrence in the business world between firms seeking to achieve strategic value for themselves. M&A deals always make media headlines probably due to the huge amounts of cash that some of them entail, sometimes involving billions of US dollars which may exceed the GDP of some small countries. The main reason for their occurrence is to boost the shareholder value of both firms and this is also used as a performance measure to gauge the success of M&A (Galpin & Herndon, 2007). M&A is used as a survival tactic during tough economic times and in most cases involves strong companies buying out smaller ones to create more cost-efficient, competitive companies. M&A can either take place between firms operating within a country’s borders (domestic M&A) or beyond a particular country’s boundaries (global M&A). This article will provide a general overview of merger and acquisitions and then compare and contrast the domestic and global M&A using a few case studies (Aoki, Jackson & Miyajima, 2007).

Effects of young peoples obsession with physical appearance Essay

Effects of young peoples obsession with physical appearance - Essay Example This research will begin with the statement that Physical appearance has become an obsession. Not only do individuals focus on their appearance but also the society puts a lot of emphasis on this factor. Beauty, fashion and weight are often seen as an obsession of all the youth. Most of the people in the West are obese which is emerging as a common problem and the rule there goes as you should either be super skinny or die.

Athena :: essays research papers

Athena The god to be the topic of discussion in this report is Athena. Athena was an important member of the Olympic pantheon. She was born fully armed from the forehead of Zeus, the chief god. Athena was Zeus's favorite child. He entrusted her with the Aegis, his breastplate, and with his thunderbolt. Athena's role as a goddess varied. She was a major warrior and most images depict her dressed in armor and holding a spear. In Homer's Iliad, she is described as a fierce battle goddess who continually intervened on the side of the Greeks. She also took an interest in handicrafts and agriculture. The olive tree, which she said to have created, is sacred to her. She was noted for her wisdom which explains her close association with the owl, an ancient symbol of wisdom and reason. The most famous temple to Athena was the Parthenon (5th century BC) which was named for Parthenos ("the Maiden"), which still stands atop the Acropolis in Athens. The interior of the Parthenon stands a statue of Athena Parthenos, sculpted by Phidais. When I was reading through myths, I decided I would talk about "The Gift of Athena" which, in my opinion, best illustrates Athena's colorful personality. Here is how "The Gift of Athena" goes: Long, long ago, when this old world was a very young place, and when the few people there were had just begun to live together in groups for their own protection, the great gods selected the places for humans to build the cities. They looked down upon the earth, through the clouds that shrouded their home on the very peak of the high mountain called Olympus, and they chose the sites they thought would provide everything mortals needed to live and prosper. Now, each god and goddess was eager to have a great city built in his or her honor, and so the prime locations-the very best places for the great cities to be built came to cause much bickering and jealousy among the many deities for all wanted a great city built in their honor, a city whose people would worship that particular god or goddess above all others. It happened that great Zeus, the king and ruler of all the gods, had found a spot on earth that appeared absolutely ideal for the building of a noble city; indeed, he foresaw that the city that would be built there would someday become the noblest city on earth. Well, you can imagine that all the gods and goddesses wanted this city for their own, and you would be right.

The Effects Gatorade Has on the Body

When straining your body through physical activity, Gatorade keeps your body hydrated, keeps the electrolytes balanced, and replenishes carbohydrates. However, Gatorade has several negative effects as well, which can be extremely toxic to the body. This very popular drink has both positive and negative effects that the consumer should be aware of. Proper hydration is a key aspect of keeping the body functioning at maximum efficiency. As the human body is composed mainly of water, one can imagine how necessary it is to maintain a proper balance of fluids.According to Dr. Katie Johnson, MD, 75% of Americans are chronically dehydrated. This means that Americans are not consuming enough fluids and their bodies could suffer long term effects, such as kidney failure or worse, coma. When preforming strenuous activities, fluids are rapidly lost through sweat and other bodily processes which can lead to dehydration. Gatorade was designed to quickly rehydrate the human body during these situat ions. The proper amount of electrolytes in the body keep it chemically balanced.Many normal bodily functions are dependent on electrolytes. According to www. dictionary. com electrolytes are any of certain inorganic compounds, mainly sodium, potassium, magnesium, calcium, chloride, and bicarbonate, that dissociate in biological fluids into ions capable of conducting electrical currents and constituting a major force in controlling fluid balance within the body. Whenever a person perspires, electrolytes escape from the body. If too much is lost, the body can’t function optimally.Gatorade is formulated to carefully provide the same electrolytes to keep the body hydrated, balanced, and working properly. The positive effects of Gatorade are clear, but what most do not know is that Gatorade can have just as many negative effects. Gatorade was designed with the athlete’s body in mind, but as any company knows, when the target market expands, the profits expand. With its mult i-colored, variously flavored drink line, Gatorade appeals to more than just the athletic demographic.The sedentary lifestyle of many Americans is not compatible with the intended design of the drink, which can be harmful. The body is affected negatively when a person habitually ingests Gatorade without burning off the excess compounds. The result of this build-up can be fatal as the compounds may reach toxic levels. The amount of sugar in Gatorade has Public Health advocates pushing to ban it in school systems as there is as much as two-thirds the sugar of sodas, and more than three times the amount of sodium.In one 32oz bottle of Gatorade there are 56 grams of sugar and 440mg of sodium. There should be a clear separation between â€Å"healthy alternative† and â€Å"junk food†, but with Gatorade that line is more blurry than one would think. For the person with the active lifestyle Gatorade is an ideal drink. It replenishes the body and keeps the consumer healthy. If someone drinks Gatorade without working out it can be extremely dangerous and even potentially fatal. Gatorade was made with the athlete in mind, so remember this when consuming it.

Critical Analysis of Upton Sinclairs The Jungle Essay

The Jungle is a novel that focuses on a family of immigrants who came to America looking for a better life. The novel was written by Upton Sinclair, who went into the Chicago stockyards to investigate what life was like for the people who worked there. The book was originally written with the intent of showing Socialism as a better option than Capitalism for the society. However, the details of the story ended up launching a government investigation of the meat packing plants, and ultimately regulation of food products. It gave an informative view of what life was like in America at the time. Important topics like immigration, working conditions and sanitation issues of the time were all addressed well in the novel.†¦show more content†¦As they set out on the voyage to America, they were tricked by an officer into taking his passport, and another officer arresting him and charging him for it. They were also cheated out of their savings when they arrived in New York when an a gent forced them to stay in his lodge that was much too expensive for them to afford (18). But when they reached the town, a stockyard called Packingtown where Meat Packing Plants were, it shows just how much advantage was taken of all these immigrants. Real Estate places would build houses out of poor material, then advertise the old houses as brand new for three times the cost it was to build them (69). The houses also had charges on interest, taxes, water and insurance that were not explained up front to the immigrants, who were unable to read and comprehend the deeds they would sign. All the jobs were paid at desperately low wages due to the high number of demand for work, since there were so many people that had immigrated and ended up homeless and poor, and needed a job to survive (83). The working conditions for these immigrants at the meat packing plants were appalling and displayed how badly in need of a change they were. Workers in the factory that did unskilled labor would be paid only somewhere between a mere fifteen to twenty-five cents an hour. They would have to work from early in the morning until it was dark at night, with only a half hour break for lunch.
