Do Flies Really Vomit and Poop When They Land on You

Lets get to the bottom of a common belief about flies: do they really vomit and poop when they land on you? Where There Are People, There Are Flies First of all, we need to be a bit more specific. Were talking about houseflies here—known by scientists the world around as Musca domestica—the house fly associates with people. Virtually anywhere on the planet where you can find people, you will also find Musca domestica. Anyone who has ever enjoyed a backyard barbecue knows that house flies crash your picnic table, walk all over your potato salad, and attempt to taste your burger, should you dare to leave it unattended for just a moment. And occasionally, those flies will come to rest on you. So you are probably wondering what theyre up to while they sit there. Its a totally understandable and realistic concern. Yes, House Flies Vomit (a Lot) Lets tackle the first bit of this question first. Do flies vomit on you? The answer is a resounding sometimes. House flies do vomit, sort of, and they do so pretty often. Unfortunately for the house fly, it is not equipped to chew solid foods. Most insects that feed on solid food—beetles, for example—have chewing mouthparts, with which they can properly masticate their meals into tiny, digestible bits. House flies were instead blessed with sponge-like tongues. Only in flies, we call their tongues labella (the singular is labellum, but the fly has a matched pair). House flies taste with their feet, so they have no choice but to walk on their food (and ours, should they be sampling our picnic menu). When a house fly comes upon something that seems like it might be yummy—keep in mind that dog poop is the kind of thing house flies find yummy—it will reflexively stick out its labella and press them against the potential food item to investigate. Liquids can be slurped up without much effort. Inside the house flys head is a structure called a cibarial pump (or food pump), which generates a suction to draw the liquid up through channels in the mouthparts (called pseudotrachea). So, how does the house fly make a meal out of meat, or any other solid food (like dog poop)? It uses those same mouthparts to liquefy the entrà ©e. The house fly dabs the tasty morsel with digestive enzymes by bringing up a little regurgitated food and saliva. The enzymes begin breaking down the solid food, gradually turning it into a slurry the house fly can then lap up. Meat milkshake, anyone? House Flies Also Poop (a Lot) Now, think about the last time you had the stomach flu. Anytime you vomit repeatedly, you run the risk of dehydration, so you have to drink a lot of fluids to replace the ones you lost. Flies are no different. This liquid diet means flies require a lot of water. And when you drink a lot of water†¦well, lets just say what goes in, must come out, right? So flies do a lot of defecating, too. Therefore, in answer to the original question, Do flies really vomit and poop when they land on you? Yes, they do, but not every single time they land on you. They void when they land on food. It really depends on whether or not the fly thinks you are a potential meal. If the fly gets a message from its feet saying, Hmm, this guy tastes pretty good. Take a lick! youre probably going to get a little fly vomit on you. And hey, if the fly has got to go, its got to go, so you might just get a little fly poop on you, too. Should You Worry? Yes, you should worry. Houseflies are strongly suspected of transmitting at least 65 different diseases to humans, including typhoid fever, dysentery, cholera, anthrax, leprosy, and tuberculosis. A single housefly can carry over one million bacteria. Before modern antibiotics were invented, flies were definitely deadly. It is important to control any type of fly that may be indoors or in your backyard, by killing the individuals and by eliminating the food waste in which they feed and reproduce. Practice good sanitation, indoors and outdoors, and wash your hands frequently.

Captain Americ The First Avenger Essay - 983 Words

The movie, â€Å"Captain America: The First Avenger,† involves two posthuman characters, which Marvel Comics created. Captain America is a super hero, who is known as the world’s first super soldier and many humans look up to him all over the planet. Red Skull is a super villain and is known to create havoc and terror in the lives of humans. Post humans can challenge the idea of community in several ways, but one factor that tends to stay the same, relating to posthumans, is that humans can easily be persuaded to follow in the footsteps of someone they believe is superior to them, such as Captain America or Red Skull. To begin, a doctor, named Dr. Erskine, from New York, New York created Captain America in 1941. This was a time when Americans were very proud of their nation and centered everything around World War II. The community was mostly anti-German, since Germany was one of the three countries America was battling during World War II. Captain America, who was known as Steve Rogers before he transformed over, was a scrawny boy who failed to meet the requirements to join the military. Eager to join, Steve Rogers volunteered himself for an operation that Dr. Erskine planned to conduct, which would alter his physique to that of a super human. After ingesting the â€Å"Super Soldier Serum,† Steve Rogers transformed into Captain America. His muscles and reflexes were greatly enhanced, as well as his height and frame. An agent from Nazi, Germany assassinated Dr. Erskine because he

Write About the Ways Love Is Explored in Two Soliloquies free essay sample

Shakespeare expresses the theme of death throughout Romeos soliloquy to enable the audience to empathise and feel pathos toward Juliet â€Å"Death that hath suck the honey of thy breath†. The word â€Å"breath† is ironic and is symbolic of how Romeo cannot bare to be without Juliet, so much so that he feels the sensation of suffocation. Dramatic irony is also apparent as the audience knows that Juliet is still alive; this sentiment provokes emotion as the audience is willing for Romeo to notice that she is not dead. Also the fact that love is blind plays an ironic almost humorous part here as Romeo is failing to see Juliet is still alive. The theme of death continues as Shakespeare personifies death throughout the soliloquy to present it as a more sinister force and rival for Juliet’s love: â€Å"shall I believe that unsubstantial death is amorous? And that the lean abhorred monster keeps thee here in the dark to be his paramour? † The negative language negative language used to personify death, â€Å"lean abhorred monster†, illustrates Romeos sense of disgust but more importantly, the fear that death has taken Juliet from him. Romeo’s fear is clearly expressed when Shakespeare writes: â€Å"For fear of that I still will stay here with thee/here i will remain†. The repetition of â€Å"here† conveys Romeos determination to stay with Juliet to the extent that he will take his own life. Therefore, the audience get the impression that Romeo feels he must kill himself to preserve their love, a trait which links with his hamatia. Furthermore, Shakespeare employs the ongoing lexical field of death to create a sense of foreboding and heighten the dramatic irony. The main protagonist Romeo personifies death using a metaphor to express its severity. He explains how death has not â€Å"conquered† Juliet’s beauty â€Å"yet†. The word yet implies that death is inevitable which links to the phrase â€Å"star crossed lovers† that is delivered in the prologue. Elizabethan people were highly superstitious and believed heavily in fate which would have contributed to the many attributes that make Romeo a tragic hero. â€Å"And deaths pale flag is not advanced there. Shakespeare‘s use of nautical language is used to infer how Romeo has almost been â€Å"shipwrecked† (as he says later in the soliloquy) which highlights his solitude and his incomplete sensation he feels without Juliet present. In Addition, the audience so observes that Romeo’s obsessive and unconditional love for Juliet contributes to his fall from grace and greatly adheres to his hamartia. â€Å"Thee here in dark to be his paramour/hereâ €™s to my love†. Dramatic irony and a paradox of light is used her to show Romeo’s possessiveness and impetuousness. The fact that he says â€Å"my† shows his obsessive naivety, as he almost loves Juliet too much so to speak. It is clear for the audience to see that Romeo is ruled by fate, doomed from the start. A contemporary audience would have profoundly disagreed to this ethos as in a modern way we believe that we choose or make our own â€Å"fate†. Contrastingly Shakespeare uses powerful repetition to emphasise the importance and severity of Othello’s opening line. The use of monosyllabic words creates tension, highlighting Othello’s chilling tone. It is the cause, it is the cause my soul â€Å". Here Othello is addressing his soul and conscience, trying to justify the terrible act which he is about to commit; but in his mind he already has established the inevitability of his actions. The fact that Othello uses the word â€Å"It â€Å"shows he cannot bring himself to name the act that Desdemona has supposedly committed. Even this early in the soliloquy, the read er can clearly distinguish Othello’s hamartia (the traits that make a tragic hero). We see his serious errors in judgment (believing Iago without proof) which later leads him to committing the dead (Taking Desdemona’s) that leads to his downfall. Additionally, Othello changes the address of his soliloquy from his inner self, to the â€Å"Chaste stars â€Å". It is a commonly known fact that the Elizabethan era were very superstitious; so it is very understandable that they could empathise with Othello’s â€Å"cause â€Å" and understand his alliance with the stars. â€Å"Let me not name it to you, chaste stars â€Å". This is reminiscent of the prologue in Romeo and Juliet, where it refers to â€Å"star crossed lovers â€Å", the audience can now see a clear correlation between obsessive love and death, which is sad as in both plays the deceased lovers are â€Å" innocent â€Å". Here Othello is further trying to reassure himself that he is doing the just thing; that his actions are almost written in â€Å"alabaster â€Å"inevitable. Referring to the â€Å"chaste stars â€Å" is also part of Othello’s hamartia; the idea of being doomed from the beginning . Also his obsessive, overpowering love for Desdemona, distorts his perception of reality, which is why he failed to detect the lies being fed to him by Iago. Shakespeare uses dramatic irony to highlight Desdemona’s innocence, the fact that Othello says â€Å"chaste â€Å"is almost humorous as the audience knows that Desdemona is completely innocent, never committing adultery in her extremely short life. Just as Romeo speaks of Juliet’s beauty, even in death, to emphasise his love for her, so too does Othello in acknowledging Desdemona’s outward perfection and beauty. â€Å".. hiter skin than snow/And smooth as monumental alabaster.. † Here Shakespeare uses and extended metaphor, which is ironic as Othello is comparing Desdemona to white snow, white being symbolic of innocence and purity which paradoxes the vile dead which he is about to commit. Shakespeare use of figurative language here powerfully reflects Othello’s intense love and adoration for Desdemona. The fact that Othello elevates Desdemona to a position of â€Å"Monumental† perfection shows that he is savouring her beauty before confirming his resolve that â€Å"she must die†. Furthermore, Shakespeare’s clever use of dramatic irony and ability to control the audiences’ emotions through powerful imperative verbs is shown in this part of the soliloquy. â€Å"Yet she must die, else she’ll betray more men†. Othello’s resolve is highlighted by a break in the flow of the verse, emphasised by a colon. This break represents his sorrow, regret and anguish. The fact that Othello is a â€Å"Moore† means he suffered both outwardly (isolation and alienation attacks) and inwardly (tortured conscience). Unfortunately the finality of this statement conveys to the audience the harsh reality that Othello is going carry out this injustice. Also this particular line said by Othello links with what Brabantio (desdamona’s father) says in the beginning of the play â€Å"Look to her, Moor, if thou hast eyes to see: She has deceived her father, and may thee†. This here is very ironic, as Othello is going to murder Desdemona for the exact thing her father warned him about, except she has not committed the act. We the audience feel pathos toward Desdemona as even her father had a false predicament and made an extreme error in judging his own daughters character. Unsurprisingly this links with Romeo and Juliet’s struggle to be together as a result of the â€Å"family feud†. Love is portrayed to be a hardship in both plays, which may be one of the reasons the love is so obsessive and unhealthy. To conclude, I believe that the theme of love is convayed very effectively in both Romeos and Othello’s soliloquy. Both invoked a variety of emotions and allow the audience to really connect with the characters. A great amount of dramatic irony and tension is delivered at pivotal points in both plays where obsessive leads to the suicide of Juliet and contrastingly the murder of Desdemona.

Is China nuclear weapons arsenal a force for stability or instability in Asia

Introduction Different countries have different reasons for possessing dangerous ulcer weapons. Many of the countries in possession of the weapons cite defense as their foremost reason. It proves difficult to ascertain the exact number of the weapons a country possesses due to the high level of secrecy involved. For instance, as revealed by the federation of American scientists, China records approximately 180 full of zip nuclear weaponry but owning 240 of them in summation as recorded in the 2009 statistics.Advertising We will write a custom essay sample on Is China nuclear weapons arsenal a force for stability or instability in Asia? specifically for you for only $16.05 $11/page Learn More Despite of these, China is the â€Å"second smallest country that possesses such weapons as compared to other five major states possessing these nuclear weapons† (Kristensen, Robert, Matthew, 2006, p.53). However, what triggers the minds of many is whether th e Chinese nuclear weapon arsenal is stability or an instability force in Asia. As the paper unfolds, China’s nuclear weapon arsenal stands out as a force for stability in Asia. Discussion China has signed various treaties for its safety use of its nuclear weapons. It is one of the countries, which have signed the nuclear nonproliferation treaty. The treaty, ratified by China in 1992, illustrates the commitment of China in using its nuclear for the purposes of stability of its continent as opposed to causing instability (Kristensen, Robert, Matthew, 2006, p.45). Therefore, the claim alone is a package enough to declare the Chinese nuclear weapon arsenal a stability force in Asia. Furthermore, among the five states, China gave an assurance of security to those countries without possession of nuclear weapons. Furthermore, the Chinese policy â€Å"no first use rule† asserts their concerns on stability. This policy means that the use of their nuclear weapons will come as t he last resort if the circumstances require that they use them. As Michael (2011, Para. 4) observes, â€Å"The white paper of 2005 released by the foreign ministry states that the government would not use its weapons under any circumstances and at any time as its first option† during any time of war. It further postulates that China will under no circumstances use nuclear weapons on a non-nuclear weapon state. Furthermore, China has, of recent had good relations with other countries, the US being among them. For instance, in the status and evolution paper on the china nuclear arsenal, union of concerned scientists assured the world that China had no intention of enhancing any parity with the Us (Michael, 2011, Para.5). Further, the paper raised the concern of its arsenal being able to protect the people of China in order for it to survive any attack and have the ability to retaliate. This therefore, implies that China has no ill intention of its nuclear weapon causing any for m of mayhem but rather fosters stability of its country as well as the safety of its people.Advertising Looking for essay on international relations?

It proves therefore important to note that China is not the only country in possession of such weapons of mass destruction. Although issues have been raised concerning the ill motives of China’s possession of the firearms and secret manufacturing of these weapons, it remains not clear to tell what decision the country can come up with tomorrow. The various treaties signed on usage of the weapons remains the only reference point, but overall, the Chinese nuclear weapons exist purposely to foster stability of the country and only used as the last resort.
