A Membrane-Enclosed Nucleus Essay They are very smallindividually not more than one single cellhowever there are normally millions of them together, for they can multiply really fast. A number of bacteria cause disease, these are called pathogenic bacteria. Fortunately our immune system knows how to deal with them. However not all bacteria are bad guys. We need bacteria to stay alive. Bacteria are prokaryotes (single cells that do not contain a nucleus). Microbiology is the study of prokaryotes, eukaryotes and viruses. Did you know that bacteria can get sick too. Bacteriophages are able to attach themselves to certain types of bacteria and inject their genetic material in the bacterial cell. Then, using the bacterial machinery, the DNA multiplies itself. Eventually from this multiplied genetic information so many new bacteriophages are formed that the cell bursts. The offspring of the bacteriophage has destroyed its bacterial host, and in so doing millions of new bacteriophages are released. These can attach themselves to new bacteria to complete their life cycle. With our immune system we defend ourselves against a bacterial infection. Antibiotics can help us win the battle. When you report a bacterial infection to your physician, you are probably prescribed antibiotics. The term antibiotics (literally against living things) is mainly used for substances that kill or prevent the growth of bacteria, as opposed to antiviral or antifungal substances. Antibiotics are not active against viral infections. Antibiotics are extremely important in medicine, but unfortunately bacteria can become resistant to them. Antibiotics have probably been around nearly as long as microorganisms have, and nature has provided bacteria with means to overcome their action. Resistance to antibiotics can become problematic, for it makes these powerful medicines completely ineffective. Some bacteria have learned to deal with practically all types of antibiotics we have available, and this can cause real problems in health institutions. Strict quarantine measures are needed to prevent the spread of such superbugs for we have little weapons left against them.

Literary Analysis of Dr. Seuss Essay -- Dr. Seuss Books Literature chi

Literary Analysis of Dr. Seuss Theodor Seuss Geisel, better known as Dr. Seuss, is perhaps one of the most beloved children’s authors of the twentieth century. Although he is most famous as an author of children’s books, Geisel was also a political cartoonist, advertisement designer, and film director (Kaplan). He used the power of imagination to produce unforgettable children’s books and helped solve the problem of illiteracy among America’s children. By using his experiences in life as a foundation for most of his books, Theodor Geisel created a unique writing style that incorporated various elements and techniques, enabling his books to appeal to people of all ages.   Ã‚  Ã‚  Ã‚  Ã‚  The animated life of Theodor Geisel is evident in his literary masterpieces. He was born on March 2, 1904 in Springfield, Massachusetts to Theodor and Henrietta Geisel (Ford 14). Geisel grew up speaking German and English, and his fascination with quirky words began at an early age due to his family. For example, his sister, Margaretha, called herself Marnie Ding Ding Guy, and his first creation was the Wynnmph with ears three yards long (Kaplan). During his childhood, Geisel read widely and often - developing his voracious reading habit at an early age. By the time he was six years old, Ted was already reading Charles Dickens and Robert Louis Stevenson (Kaplan). However, college education never interested him. Labeled â€Å"Least Likely To Succeed† by his fellow classmates at Dartmouth University, Theodor often got in trouble for partying and was forced to resign from the school humor magazine. This gave birth to numerous pseudonyms of Geisel, such as L. B urbank, Thomas Mott Osbourne, Ted Seuss, Seuss, Dr. Seuss, and Theo LeSieg (Hurst). In his adult life, Theodor created various political cartoons for Judge, a humor magazine, and PM, a noted political magazine. The illustrations in these early cartoons foreshadow the quirky illustrations found in his children’s books (Kaplan). Geisel turned to writing children’s books when creating numerous ads for the popular insecticide, Flit, left him with little to do during the winter months (Hurst). By 1990, Dr. Seuss had written over forty books, two of which were Caldecott Honor books, and won two Academy Awards for his documentaries (Krull 39). Unfortunately, battling glaucoma and cataracts became too much for Theodor; he died on September... ...hors who got away with moralizing. The quirky illustrations and creative wordplay enable his readers to enjoy his books, while at the same time recognize morals (Hurst). Because of his innovative approach to writing books for children, Dr. Seuss has influenced American society immensely. The Oobleck he created in Bartholomew and Oobleck became the green, slimy gunk now seen on popular television networks, such as Nickelodeon (Ford 66). Furthermore, his publishing company, Beginner Books, produced a new series of children’s books called the Berenstein Bears, enabling children to enjoy more reading (Kaplan).   Ã‚  Ã‚  Ã‚  Ã‚  Dr. Seuss revolutionized children’s literature and instilled in children the desire to read. According to literary critic Clifton Fadiman, â€Å"Theodor Geisel Seuss provided ingenious and uniquely witty solutions to the standing problem of illiteracy among children (qtd. in Kaplan).† Due to various influential figures and profound experiences during his lifetime, as well as expert use of creative literary techniques, Theodor Seuss Geisel’s children’s books continue to compel readers of all ages – allowing them to escape into different worlds filled with nonsense.   Ã‚  Ã‚  Ã‚  Ã‚  

Comedy of Errors Essay

â€Å"The Comedy of Errors† Plato states that: â€Å"The measure of a man is what he does with his power. † But is this true? Or does it depend on a person’s money and possessions? Perhaps it is the family they were born into, or even their gender. And how can reputation affect your class standing? In â€Å"The Comedy of Errors† William Shakespeare explores the interplay of these various possibilities that can determine a person’s class. Shakespeare shows us that a persons family can determine their social status. As well as affect how they are treated. Taking for example the twin Dromios, they came from an extremely poor family. â€Å"A mean woman was delivered / Of such a burden, male twins, both alike. † (?.?. 54) Because their mother was so poor they were adopted by Egeon, however as opposed to becoming his children they became servants for his biological children (also twins) with each twin receiving his own minion. Throughout the Dromios lives they remained servants, even when they were split apart they stayed with their master. Being servants for different masters meant that they were treated differently. Dromio of Ephesus was beaten and kept uneducated â€Å"I have some marks of yours upon my pate, / Some of my mistress’ marks upon my shoulders, ( I.?. 83) While Dromio of Syracuse was given an education and treated like a brother as opposed to a servant, Antipholus of Syracuse demonstrates: A trusty villain, sir, that very oft, When I am dull with care and melancholy, Lightens my humor with is merry jests. (I. II. 19) If they had had wealthy parents with much more power then they would never have become servants and would most likely have servants of their own. Another and perhaps more common way to define a person’s social status is by their wealth, that is their money and possesions. Even though in our modern society wealth has little to do with your social status, in William Shakespeare’s time the more money you had the more power you had. For example Adriana and her husband Antipholus of Ephesus, clearly their money and possessions greatly benefited them in life. All this wealth leads them to have a very good reputation. However if their reputation gets tarnished they will lose their money and in consequence their power: If by strong hand you offer to break in Now in the stirring passage of the day, A vulgar comment will be made of it; And that supposed by the common rout Against your yet ungalled estimation. (III. I. 47) Looking at this quote it is clear that if Antipholus goes through with his threat, his reputation will be tarnished. Therefore he decides against it. â€Å" You have prevailed. I will depart in quiet / And, in despite of mirth, mean to be merry. (III. I. 156) An additional example is Solinus the duke of Ephesus. When he is ready to execute Egeon he uses the power he has to grant him one day of freedom. Duke: Now trust me, were it not against our laws, Against my crown, my oath, my dignity, My soul should sue as advocate for thee. But thou art adjudged to the death, Yet will I favor thee in what I can. therefore, merchant, I’ll limit thee this day. By giving Egeon a day of fr eedom the duke boosts his reputation in Ephesus as a sympathetic and selfless leader. All the while knowing that there is no way Egeon will accomplish his goal. The third and perhaps most prominent way of defining a person’s social standing is their gender. A factor that is still entrenched in our modern society. In â€Å"The Comedy of Errors† there are many obligations women have to fill that men do not. For example as Egeon is telling the duke his tragic story he mentions that although his wife was not in love with him and did not want to marry him, they clearly ended up married. â€Å"In Syracusa was I born and wed / Unto a woman happy but for me. (I. I. 37) This quote demonstrates that as a woman one of her obligations was to get married, even if it was to someone she did not love. This also makes evident the fact women were not free to make their own decisions. Furthermore women were often considered lesser beings than men, they were not allowed as much freedom as their spouse was. â€Å" Good sister, let us dine and never fret. / A man is master of his own liberty. † (II. I. 6) This quote highlights that fact that men were free to come and go as they pleased whereas women were not.
