Starved Fruit Flies

The mechanism that triggers food foraging of wide variety of animal species has been studied for a long period of time. The significance of studying genetics and behaviour of flies or other organisms is that it would be used to understand other complex animals such as humans. “almost 75% of genes responsible for human diseases are observed to have homologs in Drosophila fly” (Pandey, U. B., & Nichols, C. D. ,2011).
Moreover, one of the most available and favourable animal model used to study is the fruit Drosophila melanogaster. “Drosophila has been a key experimental subject in genetics since the early 1900s. It was initially chosen to study by T.H. Morgan because it can be raised easily in laboratory, and the life cycle and mating can be arranged inexpensively.” (Scott F., Mike H., & Joan S, 2014).
Furthermore, “Drosophila has ~ 68 …show more content…
The main objective of this experiment was to determine whether the starved fruit flies would feed on a poor diet nourishment such as banana flavoured sucrose regardless of their gender. The hypothesis to be tested, in other words the null hypothesis (was that the foraging of the fruit flies is independent on their gender and therefore the responses would be equally distributed through all possibilities. Rover and sitter fruit fly larvae perform different patterns of hunting behavior when searching for food. Rovers show longer foraging marks on food and have a greater tendency to leave a patch of food than sitters do. This behavioral alteration is shown only in the existence of a food source. (M.B. Sokolowski,2001). The Drosophila in this research that fed on sucrose were identified by the red color on their abdomen and those feeding on banana were identified by a blue color on the abdomen, as both these food pieces were marked with the respective food color. Later on, the flies were investigated using snapshots and

Central America Neertruda Stuffa Analysis

...of our land, yet here we see the opposite mindset. The U.S. had “crowned” the rise of many dictators who were pro-U.S. With rising debt in Central America, capitalism was presented as the means to prosper like us causing envy. The aim was not UFCO, but a fight against communism, and creating free trade. Trujilo, Tachos, Carias, Martinez, and Ubico were all U.S. backed dictators that came to power. (Dominican Republic, El Salvador, Guatemala, Honduras, Nicaragua) Neruda calls them flies which is fitting. Flies are attracted to rotting things and corruption is certainly rotten. These dictators twisted and turned the laws and people for their own gain like acrobats at a circus. They wisely paid off the debts of their country and lined their own pockets at the expense of the masses. Dictators continued to slaughter those who chose to rebel. This is the meaning of submissive blood. Marmalade refers to the export of sugar and fruit. Mix the two together and you get marmalade. Here you see fruit woven into the mix...

Compare and Contrast the Ways in Which the Authors William Shakespeare, George Orwell and Jeanette Winterson Examine the Effects of Control in Their Texts the Taming of the Shrew, Nineteen Eighty-Four and Oranges Are Not the Only Fruit

...of control in their texts The Taming of the Shrew, Nineteen Eighty-Four and Oranges Are Not the Only Fruit. William Shakespeare’s comedy The Taming of the Shrew attempts to present a comedic mockery of 16th century values. Shakespeare presents to the audience the farce of marriage values, the treatment of women and the control employed to tame those who were deemed ‘unruly.’ Shakespeare uses this technique in order to highlight to his audience the ridiculousness and brutality of their actions and, furthermore, to present to a modern audience the upheld expectations and beliefs of 16th century society and the ridiculousness of said societal values. The very title of the play alone – “The Taming of the Shrew” – through the language “taming” and “shrew,” indicates that there is something undesirable about a women acting of her own accord and thus she requires ‘taming.’ In the 1949 novel Nineteen Eighty-Four, George Orwell uses control in an attempt to warn the reader of the dangers of totalitarianism after having witnessed the harrowing lengths that governments were willing to go to in order to sustain sovereign authority. Orwell was deeply disturbed by the cruelty and oppression that he had witnessed in Communist countries and was concerned by the increasing use of technology as a means of control; as presented by his use of the telescreen.

Case Study

...Corn Integrated Pest Management     ​​ Integrated Pest Management (IPM) is a holistic approach to monitoring pest lifecycles and prevalence in farmer’s fields to determine the best pest control methods to protect crop yield potential in the current and following growing seasons. IPM is a continuum of pest management evaluations, decisions, and controls that encompass pest lifecycles and prevalence, agronomic practices such as crop rotation, seed selection, soil management, and timely use of pesticides to minimize pest damage and protect environmental resources. Red Root Rot a Late Season Disease of Corn * Roots and basal stalk tissue infected with red root rot characteristically have reddish-pink, rotted roots. * Stalks are weakened and susceptible to lodging. * Premature plant death is common and can occur quickly and yield losses can be as high as 15-20%. * Genetic resistance to red root rot is uncommon and breeding for disease resistance is difficult. Management Management options are limited.  Crop rotation with a non-host such as soybean can provide some control.1 Genetic resistance has been difficult to incorporate into corn products, although the rate of disease development varies greatly between corn products. Research on inheritance of disease resistance indicates that it is a polygenic trait with additive gene action, which has complicated breeding efforts.1 Environmental stress during the season may contribute to disease infection and severity...

...CASE STUDY Brand Kingfisher : Creating a Lifestyle Brand -- Lekha Ravi Team Leader, The Icfai Research Center, Chennai. The author can be reached at lkhravi@yahoo.co.in The United Breweries (UB) group today (2008) boasts a diverse portfolio of businesses - alcoholic beverages, life-sciences, engineering, aviation, agriculture, chemicals, information technology and leisure. The man behind this potent diversity is none other than India's flamboyant tycoon Vijay Mallya (Mallya). Mallya's association with the rich, trendy and the luxurious seems to have rubbed off on his brands. All through his glitzy forays into various fields, Mallya has fastidiously endorsed Brand `Kingfisher'. His entry into aviation with the glamorous launch of Kingfisher Airlines drew a lot of its brand equity from Mallya himself. Media reports often analyze how Mallya promotes the `Kingfisher' brand by associating it with lifestyle events like horse-racing, Formula 1 racing and prestigious launches. Reflecting on how he contributes enormously to it through his own flamboyant lifestyle, it is pertinent to probe into the prospects of Kingfisher's brand extension. The Kingfisher brand has come to epitomize a lifestyle that encompasses some of the finest things in life and is today synonymous with delivering a premium experience. - Vijay Mallya Brand Kingfisher I am the brand ambassador; I am the `King of Good Times',said Mallya, the brainchild of Kingfisher brand launched in the year 1980.

...“You will know them by their fruits.” Mt. 7:16 CHRISTIAN PURITY By Randolph Sinks Foster FOREWORD The past generation produced some outstanding leaders and writers among the advocates of the Wesleyan doctrine of entire sanctification. The writings of these authors are of such high rank and their value has been so tested by time that today their books are worthy to be recognized as classics in this field of religious literature. That these writings, all of which are now out of print, may be preserved and made available to the people of the holiness movement today, the publishers are presenting this series of Abridged Holiness Classics. The abridged message is that of the original author from which has been deleted material mostly applicable to the previous generation. The man called upon to undertake the task of abridgment for the first four volumes in the series is the Rev. John Paul, who is well known as a Bible scholar and as an authoritative preacher and teacher of the doctrine of entire sanctification. That Doctor Paul has done an admirable work will be recognized by the reader of this series which starts with the following titles: “Purity and Maturity,” and “Perfect Love,” by J. A. Wood; “Possibilities of Grace,” by Asbury Lowrey; “Christian Purity,” by Bishop Foster. It is the sincere prayer of the publishers that these classics in abridged form will be the blessing to the readers of this generation that they were to the generation to which they were written originally...

Talks

...Compiled Talks of Swami Vivekananda KARMA IN ITS EFFECT ON CHARACTER The word Karma is derived from the Sanskrit Kri, to do; all action is Karma. Technically, this word also means the effects of actions. In connection with metaphysics, it sometimes means the effects, of which our past actions were the causes. But in Karma-Yoga we have simply to do with the word Karma as meaning work. The goal of mankind is knowledge. That is the one ideal placed before us by Eastern philosophy. Pleasure is not the goal of man, but knowledge. Pleasure and happiness come to an end. It is a mistake to suppose that pleasure is the goal. The cause of all the miseries we have in the world is that men foolishly think pleasure to be the ideal to strive for. After a time man finds that it is not happiness, but knowledge, towards which he is going, and that both pleasure and pain are great teachers, and that he learns as much from evil as from good. As pleasure and pain pass before his soul they have upon it different pictures, and the result of these combined impressions is what is called man's "character". If you take the character of any man, it really is but the aggregate of tendencies, the sum total of the bent of his mind; you will find that misery and happiness are equal factors in the formation of that character. Good and evil have an equal share in moulding character, and in some instances misery is a greater teacher than happiness. In studying the great characters the world has produced, I dare...

From forth the fatal loins of these two foes A pair of star-cross'd lovers take their life; Whose misadventured piteous overthrows Do with their death bury their parents' strife. The fearful passage of their death-mark'd love, And the continuance of their parents' rage, Which, but their children's end, nought could remove, Is now the two hours' traffic of our stage; The which if you with patient ears attend, What here shall miss, our toil shall strive to mend. SCENE I. Verona. A public place. Enter SAMPSON and GREGORY, of the house of Capulet, armed with swords and bucklers SAMPSON Gregory, o' my word, we'll not carry coals.

The hole was barely large enough to admit his hand and he thrust it out to feel of the air. A small soft wind blew gently from the east, a wind mild and murmurous and full of rain. It was a good omen. The fields needed rain for fruition. There would be no rain this day, but within a few days, if this wind continued, there would be water. It was good. Yesterday he had said to his father that if this brazen, glittering sunshine continued, the wheat could not fill in the ear. Now it was as if Heaven had chosen this day to wish him well. Earth would bear fruit. He hurried out into the middle room, drawing on his blue outer trousers as he went, and knotting about the fullness at his waist his girdle of blue cotton cloth.
