Why Do Bugs Die On Their Backs

Youve probably noticed a variety of dead—or nearly dead—crawly critters, from beetles, cockroaches, flies, crickets—and even spiders—in the same position: flat on their backs with their legs curled in the air. Lots of bugs die in this particular pose but have you ever wondered why? This phenomenon, common as it is, has sparked plenty of debate among amateur insect enthusiasts and professional entomologists alike.  In some respects, its almost a chicken or the egg scenario. Did the insect die because it was stranded on its back and was unable to right itself, or did the insect wind up on its back because it was dying? Both scenarios have merit, and either might actually be correct, depending on the circumstances of a particular bugs demise. Dead Insects Limbs Curl When They Relax The most common explanation for why bugs die on their backs is something called the position of flexion. When a bug is dead or dying, it cannot maintain tension in its leg muscles and naturally falls into a state of relaxation. (If you rest your arm on a table with your palm up and relax your hand completely, youll notice that your fingers curl slightly when at rest. The same is true of a bugs legs.) The argument goes that in this relaxed state, the bugs legs curl or fold up, causing the insect (or spider) to topple over and land on its back before it expires. But why would the bug simply fall over rather than face-plant? The explanation has to do with gravity. The heavier mass of the dorsal side (back) of the bugs body falls hits the pavement, leaving the lighter side where the legs are to push up the daisies. Blood Flow to the Legs is Restricted or Stops Another possible explanation involves the flow of blood—or lack thereof—in a dying insects body. As the bug dies, blood flow to its legs ceases, causing them to contract. Again, as the critters legs fold up beneath its considerably heavier body and the laws of physics take over. Ive Fallen and I Cant Get Up! Although most healthy insects and spiders are quite capable of righting themselves should they inadvertently wind up on their backs—very much like turtles and tortoises—but they do sometimes find themselves irreversibly stuck. A diseased or weakened bug might be unable to flip itself over and subsequently, it would succumb to dehydration, malnutrition, or predation—although in the latter case, you wouldnt find the bug corpse since it would have been eaten. Insects or spiders with compromised nervous systems likely have the most difficulty righting themselves. Many of the most popular commercial pesticides act on the nervous system, often causing targeted insects to go into convulsions. As the bugs uncontrollably kick their legs, they get stuck on their backs, unable to muster the motor skills or strength to turn over, again, leaving them with their legs pointing toward heaven as they make their final curtain call.

Option #1: Money Doesn’t Buy Happiness. Well, on Second Thought Ashlie Byron HRM400-1– Human Resources Development and Management Colorado State University – Global Campus Jeffery Stevens September 15, 2016 Option #1: Money Doesn’t Buy Happiness. Well, on Second Thought In Case Study 10.1, Economics professor Richard Easterlin asserted that money couldn’t buy happiness. He based his findings of studies conducted in wealthy and very wealthy countries. His theory was that if happiness indeed were a â€Å"commodity† that one could purchase, the wealthiest countries would have more purchasing power for happiness. Easterlin concluded from his research that the wealthier countries were not happier overall. One’s level of happiness did not increase with an increase in money. On the opposite end of the spectrum, individual happiness did not change between rich and poor individuals. This contrast has become known as the Easterlin Paradox. Easterlin asserted that one’s relative income (comparison between one’s income vs. another’s income) was more important than absolute income (income earned in a given time period). Betsy Stevenson has challenged Easterlin’s conclusions along with Juston Wolfers, from Wharton University, using data which included a larger sampling of countries with a more diverse GDP over a longer time span. Stevenson and Wolfers concluded from their findings that absolute income was a definitive predictor of happiness, citing that GDP and â€Å"life satisfaction†Show MoreRelatedHuman Resource Management : Human Resources Development1748 Words   |  7 PagesHuman resource management entails managing recruitment, planning, and implementing a selection of organizational development training within the business.

Ethical Principles John Durham III PSY/305 March 7, 2016 Dr. Daven Salmi Ethical Principles Introduction The ethical issue that I chose to examine was an article about the relationship between ethical and abusive coaching behaviors and student-athlete well-being. I found this article very interesting because not a lot of people are aware of the ethical issues that have been and are currently going on in the athletic background. Believe it or not there are many ethical issues that relate to psychology in the athletic field. Ethical Issues in Collegiate Athletics One of the biggest ethical issues in collegiate athletics was the abusive behaviors of the coaches to the athletes. This is a big ethical issue because the actions†¦show more content†¦A key example of the ethical and abusive behavior from a coach that this article states was the event conducted by Rutgers University previous head basketball coach Mike Rice. Mike Rice was terminated from Rutgers University for verbally (cursing and taunting) and in some instances physically (pushing and throwing the basketball at the players) abusing his players. This incident shows the coach crossing that line ethical and unethical coaching behavior. The article also included how social-cognitive theory has been used to explain the impact of coaching behaviors on athletes. One of the main aspects of social-cognitive theories impact is that individuals learn by observing and imitating the behaviors of models which in this case of course is the coa ches (Brown, Yukhymenko-Lescroart, amp; Paskus, 2015, p. 37). Coaches have highest authority over their student-athletes and control the valued outcome which makes them the most credible models in their athlete’s point of view. Another aspect that is of importance of social-cognitive theory is that individuals are capable of self-regulating their performance. The article list four mechanisms initiated by Bandura (1977) that can affect an individual’s self-efficacy, which is an individual’s belief that he or she is capable of self-regulating their performance, belief.

It all starts as soon as the plane enters this small, yet interesting atmosphere. The landing becomes a brief yet gravity pulling harsh stop. My feelings of relief come about as soon as arrival to this place I call my hometown. The weather affects your entire body as soon as you walk out into this atmospheric, scene filled place. As I step off the plane, I find myself breathing in pure, clean, and crisp air instead of intense use of gases like you would in the state of Arizona. I start to feel many tiny bumps appear on my entire body because of the surrounding sounds, beautiful sights, and the bi polar weather. The surrounding sounds contain the mysterious wind weaving in and out throughout the tall, luscious, and green trees. The sights are breath taking; there are continuous hills that find themselves winding up and down; repeat, mass fields of green grass either tall or short, and best for last are the many streaming creeks full of trickling, clear, and enticing water that is shar ed with mass amounts of crawdads and tiny fish that scatter among disturbance of the smooth water. We will write a custom essay sample on Relief of the World or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The vibe of the people here is a vibe you cannot find in a regular average city, only in a small town. Since it is a town, you know everyone and everything. The citizens of this small town are greatly caring, giving, and entirely friendly only if their crops are not being messed with. This leads to the crazy amounts of farmers. The farmer’s fields either grow crops of corn, hay, wheat and even everyday vegetables. What is farmed is their dinner nightly. People here rely entirely on their crop fields like the Joad family in the book, Grapes of Wrath. Dinners here are always appetizing. Being born here, I was raised on great, healthy meals. A lot of frying is done here. If it is a taco shell, you fry it. I mean what I say! This only happens in the Midwest which is where this small yet mighty town is located. At dinner, there are many rules: first and for most, the man of the house is the first one to get his plate filled and the first to eat, second there are NO elbows on the t able (consequences if so) and the best for last is that the women who make the meals and prepare them are the ONLY ones who clear and clean the kitchen while the men go out and do what needs to be done outside. Yes, indeed everyone has an accent. Country accents are very strong out here. Here, Church is life. You arrive early every Wednesday afternoon and Sunday morning, you are not allowed to miss unless bedridden with an illness or disease. Even though my family is separate in religion, I do still participate in their expressive activities that teach through the eyes of Mormonism. Many who abide here are of the religion, Mormon. Yet, as a family we still do many activities involving the church and mostly congregate outside; that is as if the weather has not changed its mood from sunny to drastic rain and gloomy. The weather here may be very bipolar at times, especially the summer; June through August. This time is when the monsoons and rain storms hit at any given moment with no warning! A storm may even carry some damaging hail with it. It may be sunny at the moment until a massive grey clouds roll in rapidly from no where, at least it seems that way. Sometimes the clouds can carry hail and release that hail from the cloud for five minutes or longer. If the weather continues to storm, a tornado warning may be issued. When a warning is broadcasted (radio or TV), the family and I will go to the basement and play card games until further notice of safety. Within an hour this tornado can destroy the nine-hundred acres of my grandparents land. Now, I know why some people call this state â€Å"misery† instead of its actual name. The feelings I experience here are quite unexplainable at times. When I am here, I feel many senses but one that stands out to me is the sense of relief and freedom; I’m finally home again. To me, there is no better feeling in the world when all the mistakes made, scars left, and all negativity is suddenly gone. Not a care in the world is given when I’m bridge jumping into the deep, luscious creek below. To understand beauty in nature is hard, but when you are here; you experience every ounce of love of this land. The best are the morning runs that I take. Adventuring and maneuvering through the muggy, misty forest located in the center of Plato, Missouri. This is my home; I feel whole again, I’ve missed it here.
