Boa Constrictor Facts

Boa Constrictor Facts Boa constrictors are reptiles and reside mainly in Central and South America. Their scientific name, Boa constrictor, is derived from the Greek words meaning type of snake (boa) and to grasp (constrictor). They are known for their gigantic size and for killing their prey by squeezing them to death with their muscular bodies. Fast Facts: Boa Constrictor Scientific Name: Boa constrictorCommon Names: Red tailed boa, boasOrder: SquamataBasic Animal Group: ReptilesDistinguishing Characteristics: Large, heavy-bodied, beige blotches on brown bodySize: 8-13 feet in lengthWeight: 20-100 poundsLife Span: 20-40 yearsDiet: CarnivoreHabitat: Tropical forests, grasslandsConservation Status: Least concernFun Fact: Boas are excellent swimmers, but they avoid water as much as possible Description Boa constrictors are non-venomous snakes best known for their large size and for squeezing their prey to death. They can climb surfaces well, swim, and travel up to speeds of one mile per hour. These reptiles have a life span of roughly 30 years, but the oldest ones have lived to 40 years. They can grow up to 13 feet in length and weigh from 20 to 100 pounds. The colors of their skin, such as pinkish-tan with patterns of brown and red, help to camouflage them well in their environment. Habitat and Distribution Boa constrictors live in Central and South America in habitats such as tropical forests, savannas, and semi-deserts.  Boas hide in the burrows of rodents at ground level during the day to rest. They are also semi-arboreal and spend time in the trees to bask in the sun. Diet and Behavior The tail of a rat hangs from the mouth of a boa constrictor as it ingests the body of the rat.   Joe McDonald/Corbis Documentary / Getty Images Boas are carnivores, and their diet consists mainly of mice, small birds, lizards, and frogs when they are young. As they mature, they eat larger mammals, such as rodents, birds, marmosets, monkeys, opossums, bats, and even wild pigs.   At night, boas hunt using sensing pits on their face that allow them to detect their preys body heat. Because they move slowly, boas rely on ambushing their prey; for instance, they may attack bats as they sleep in trees or as they fly by. They kill by using their powerful muscles to squeeze their victims body. Scientists thought this squeezing suffocates their prey, but recent findings show that the powerful pressure from the snakes actually constricts blood flow in the animal. The pressure is so powerful that the prey’s heart is not able to overcome it and it dies within seconds. Once the animal is dead, these snakes swallow their prey whole. They have special tubes in the bottom of their mouth that allow them to breath as they eat their meal. Boa constrictors digest their food with their powerful stomach acids. After a large meal, they will not need to eat for several weeks. Since they are nocturnal and solitary creatures, boas hide in rodent burrows during the day to rest, but may spend several hours in trees basking in the sun. During colder weather, they can become almost completely inactive. Reproduction and Offspring Boa constrictors reach mating age at around 3-4 years. The breeding period for them is during the rainy season. Males slither across the female’s body to stimulate the cloaca with his vestigial legs. Females produce anywhere from 20 to 60 young. These reptiles are ovoviviparous, which means that they give birth to young that are fully formed. The female eats very little during the gestation period, which lasts roughly 100 days. When the eggs are ready to be born, they push out the cloaca and must break open the protective membrane they are still encapsulated in. At birth, the young are about 20 inches and can grow to 3 feet during the first several months of life. They can survive on their own and demonstrate natural instincts for hunting and hiding from predators. Conservation Status Boa constrictors are designated as least concern under CITES Appendix II, but they have not been assessed by the International Union for Conservation of Nature (IUCN). The biggest threat to boas comes from humans who harvest them for their skin as part of the leather trade. In tropical parts of the Americas, people may bring boas into their homes to manage rodent infestations. Species There are over 40 species of boas. A few examples of species are the rubber boa (Charina bottae), the rosy boa (Charina trivirgata), and the red-tailed boa (Boa constrictor constrictor). Rubber boas live in western North America. As their name suggests, these boas have rubbery skin, and they burrow into the ground. The rosy boa’s habitat ranges from California and Arizona to Mexico. The red-tailed boa is the species of boa constrictor that is most commonly used as a pet. Boa Constrictors and Humans Workers displaying yellow boa constrictor at a festival in Bowie, Maryland.   Tom Carter/Photolibrary/Getty Images Plus In the U.S., boa constrictors are often imported as pets and sometimes bred to produce more colorful snakes. While this pet trade may not pose a threat to boas, an unfortunate risk is that some owners simply release their pets into the environment because they do not realize how quickly these animals grow. This is particularly dangerous because boas can adapt well to new environments so long as the temperatures are conducive to them thriving. As a result, they can become an invasive species and pose serious threats to the new environment, which could lead to the disappearance of other indigenous species.

17th Century Timeline, 1600 Through 1699

17th Century Timeline, 1600 Through 1699 Major changes in the fields of philosophy and science took place  during the 17th century. Prior to the beginning of the 1600s, scientific study  and scientists in the field were not truly recognized. In fact, important figures and pioneers such as the 17th-century physicist  Isaac Newton were initially called natural philosophers because there was no such thing as the word scientist throughout most of the 17th century. But it was during this period that the emergence of newly-invented machines became part of the daily and economic lives of many people. While people studied and relied upon the more or less unproven principles of  medieval alchemy, it was during the 17th century that a transition to the science of chemistry took place. Another important development during this time was the evolution  from astrology to astronomy.   So by the end of the 17th century, the scientific revolution had taken hold and this new field of study had established itself as the leading society-shaping force that encompassed mathematical, mechanical, and  empirical bodies of knowledge. Notable scientists of this  era include the astronomer  Galileo Galilei, philosopher Renà © Descartes, inventor and mathematician  Blaise Pascal,  and  Isaac Newton. Here is a brief  historical list of the greatest technology, science, and invention hits of the 17th century. 1608 German-Dutch spectacle-maker Hans Lippershey invents the first refracting telescope. 1620 Dutch builder Cornelis Drebbel invents the earliest human-powered submarine. 1624 English mathematician William Oughtred invents the  slide rule. 1625 French physician Jean-Baptiste Denys invents a method for blood transfusion. 1629 Italian engineer and architect Giovanni Branca invents a steam turbine. 1636 English astronomer and mathematician W. Gascoigne invents the micrometer. 1642 French mathematician  Blaise Pascal invents the adding machine. 1643 Italian mathematician and physicist Evangelista Torricelli invents the barometer. 1650 Scientist and inventor  Otto von Guericke invents an air pump. 1656 Dutch mathematician and scientist  Christian Huygens  invents a pendulum clock. 1660 Cuckoo clocks were made in Furtwangen, Germany, in the Black Forest region. 1663 Mathematician and astronomer James Gregory invents the first reflecting telescope. 1668 Mathematician and physicist  Isaac Newton  invents a reflecting telescope. 1670 The first reference to a  candy cane  is made. French Benedictine monk Dom Pà ©rignon invents  Champagne. 1671 German mathematician and philosopher Gottfried Wilhelm Leibniz invents the calculating machine. 1674 Dutch Microbiologist  Anton Van Leeuwenhoek  was the first to see and describe bacteria with a microscope. 1675 Dutch mathematician, astronomer, and  physicist  Christian Huygens  patents the pocket watch. 1676 English architect and  natural philosopher  Robert Hooke  invents the universal joint. 1679 French physicist, mathematician, and inventor Denis Papin ​invents the pressure cooker. 1698 English inventor and engineer  Thomas Savery  invents a steam pump.

3M Essay Example | Topics and Well Written Essays - 500 words

3M - Essay Example Contemporary academic settings have acknowledged the need to develop and recognize cultural intelligence as the ability to interpret and understand diverse cultural underpinnings. In this regard, not because the way things are done in Russia are different from what 3M is accustomed to, it should already mean that the organization should not do business there – most especially if there are vast opportunities in the Russian market that could be tapped and ventured on. 3M must simply understand which cultural practices must be respected and could not be changed in their entirety. As a multinational organization that operates in other parts of the world, it already has vast experience and understanding of cultural diversities and how they can adapt and adjust to the way of life to succeed in Russia. Honestly, I strongly believe that 3M could do business in Russia provided that they respect the cultural values and traditions of its people. Being an organization that promotes ethical behavior, I am sure that they have acknowledged which cultural beliefs need to be accepted and could not be meddled with. As such, by respecting the cultural norms and beliefs of the Russians, including business practices, 3M could be assured that they will proceed with smooth business interactions within the ethical standards and moral codes of discipline. The moral codes of conduct, as well as ethical standards in business are more or less universal in perspectives. 3M, as the investing organization in Russia, has the obligation to adhere to moral, ethical and social responsibilities as employer and therefore, could expect employees to conform to these obligations. In so doing, by the rules of being role models, 3M could improve the ethical climate in foreign countries where it does business with. It is one’s contention that a practical middle ground could be established by finding an effective and acceptable balance between American and Russian ways

What is Hobbes account of the good Essay Example | Topics and Well Written Essays - 750 words

What is Hobbes account of the good - Essay Example Therefore, according to him, things are perceived to be good if the repercussions of undertaking it are pleasing to us. There are two forms of motion as described by Hobbes: vital motion, which runs through the entire existence span of a living creature such as the flow of blood and voluntary motion, which is processed through imagination, followed by execution of the thought. In defining what may be perceived as good, Hobbes argues that good usually produces a motion deep inside us; the motion experienced is referred to as ‘delight.’ Sovereign states do play an important role in ensuring harmonious existence of different people. This is because the sovereign states have laws, which people have to abide to, failure to which they are to face punishment. In avoiding punishment, people try to avoid doing any act that is against the stipulated laws; thus, promoting harmony. Absence of such regulating authority would lead to people undertaking different activities based on th eir perceptions. For example, a man could sleep with anyone at any location and perceive it to be good because it brings forth delight to him. How Hobbes’ account of the good is related to his account of the constitutions â€Å"of Man.† Hobbes account of the good is related to his account of constitution of man in that mechanical effects of their senses trigger human actions. According to Hobbes, a man uses his volition to direct his actions away from harmful or evil situations, and towards beneficial situations. Hobbes employs the word appetites as well as aversions to explain conflicting desires of a man. Some human appetites are natural for instance, food desires while others emanate from a man’s experiences. Certain appetites emanate in the body of a man and are experienced as disruptions and sufferings that should be overcome. Therefore, every man is stimulated to act in a way that tends to ease his discomfort, safeguard and enhance his well-being. Similarl y, a man’s actions are dictated by this innate inclination to easy the physical challenges which impinge upon his body. Desires for some ‘good’ changes with time, even though a man cease to survive if he ceases to have desires for good things. In other words, it is the nature of man to search and desire for the ‘good’ such as wealth, power and diet to achieve satisfaction of his desires. A man’s power is a strategy to achieve a better future, ‘the good’. Human power is categorized into one natural power that comes from innate capacities of his mind and body such as strength, ability, artistic capability and brevity. Secondly, instrumental power that emanates from the acquired faculties as well as friends benefits, reputation or resources. The enduring perpetual and endless appetites for power are an essential quality common to all human beings. Similarly, fear of powers and authorities of other people serves as a counterbalance fo r the power desires and prevents human beings from often competing to attain power. Addition, fear of death, war and accidents stimulates men to seek harmony (common good for all). Description of the distinctly social nature of the desires that are common to us There is impossibility for a people to live without desires just like the way they can live without imaginations. Moreover, Hobbes describes happiness to a continual progress of desires, which is derived from one object to another, and achieving a path that leads to other paths in life. Nevertheless, the reasons behind this

Athletes, and Sports - Benefits of Supplements in Athletic Training Ess

Athletic Benefits of Supplements The Development of drugs and supplements used by mankind has evolved from what it once was in its early stages of existence. As with all man-made things, it is said that anything made by man can be improved (Moore, p35). With this concept, almost anything in nature can apply. In this case, the development of anabolic supplements and the human body. In the later years, the usage of supplements in sporting events have helped athletes achieve new goals which could not have been accomplished through training alone. With the Human body, there is only so much room for improvement until a limit has been achieved in the progress of a persons developments. With these limits in the development in the human body, certain frustrations can result from witnessing no benefits in physical training. Even for those individuals who are ill and plague with a disease, the usage of supplements can aid that individual back to health. The same reasoning can be applied to a bodybuilder who has reache d his maximum and can no longer attain new goals. But certain questions arise when the usage of supplements are in to play, "Do they (supplements) actually working?","Are supplements hazardous to the health?","Are the supplements just a waste of money and don't benefit anything?". All of those questions are what the developers of chemist, doctors, and training consultant take into consideration before actually creating a new product or recommending someone to use supplements. The question that I would like to answer for myself, "Are supplements actually beneficial in attaining new gains and do they genuinely produce results?" The answer ... ...d talk to someone who knows and a doctor to see if any of them could prove to be lethal to you. Otherwise, those interested in quick results, see what products work best for you.

African Americans and Slavery Essay

The American Revolution was a time of great turmoil for all men and women in the United States. Great debates came and went during this time; slavery and the freedom of black men being the main problems in these debates. Slaves were used for a great number of things during the American revolutionary period. The arrival of slavery to the American colonies began in the 1600s and started out in Virginia. As the years passed more and more African-Americans were brought into the colonies to be used as labor workers. The beginning amount of slaves continued to grow and by the beginning of the revolution there were about 273,000 slaves spread throughout the American states. With the coming of the revolution all African-Americans, slave or free, knew something was coming and each had a different response to these comings. There were differences in the responses of slaves and free men during the American Revolution. There were also consequences to their choices. â€Å"Gaining freedom in a land of captivity and wresting equality from a society whose founding documents guarantee it has been the consuming desire and everlasting hope that has kept harrowed bodies and weary souls going. † In the southern states African-American slaves were treated harsher than those in the north. The plantations down south required back –breaking hours of work in the sun that White Americans believed could only be done by those they had bought. There was a reason for them to be there and until they could no longer work they were to do all things imaginable for their owners, no questions asked. Some of these slaves thought it was easier to run away from their owners and that in doing so they would have a chance to fight for their country. Slaves could either flee to the north or they could flee to Spanish owned Florida. In cases where a master was called upon to fight, they would send a slave in their place and if they lived long enough to return home they earned freedom. Many of the slaves decided that if they had a chance to gain their freedom by joining the war effort then they would gladly take their masters place. They also believed that with the beginning to the revolutionary period would bring a new deed to the land and when it was over there would no longer be a need for slaves. The consequences for slaves in the south were innumerable. Like many slaves, they took this time to run from slave masters and plantations. If these southern slaves were caught, depending on the owner, the slave could suffer mild to severe consequences. Depending on the demeanor of the owner a slave could be punished in several different ways. Whipping, branding, slapping, being dunked underwater, and kicking were just some forms of punishment. The most severe punishments were to cut off a body part like an ear in the hopes that the slave would learn and never run again. There were also â€Å"nice† slave owners that chose not to punish their slaves. There justification for not punishing their slaves was so that they would continue to work and so that the owner could buy more slaves with the money that they continued to pool in from the work. Because of some owners that continuously harassed Washington, he stopped allowing slaves into his army. But General Washington, fearing rebellion, created an order that stated that all blacks were not allowed to fight. Later he partially reversed the order and allowed only free black men to fight with him. Some slaves believed that taking a chance to flee towards the north was a far-fetched idea. They were seeking freedom in the quickest possible way. Lord Dunmore sent out a proclamation that stated in exchange for freedom any black that came to him would fight against the patriots and become a loyalist. Dunmore’s promise of freedom fueled black slaves to escape and even some patriots fled to fight as a loyalist. After the war, true to his word, slaves gained their freedom. Some of these newly freed slaves went to Britain but many of them stayed in the Americas. On the other hand free men in the north believed the revolution would bring about change for the better. Their idea of the revolution was that they were being given the chance to gain independence from Great Britain and also for themselves. It was a defining moment in history that they were to be a part of. Fighting with white men gave these free black men a sense of honor and it also gave them a job where they could earn a little money to put towards getting homes and things of that nature. Men from the north gradually began to realize that they could fight with their brethren and bring independence to the land. General Washington passed an order stating that no black man was allowed into his army. This order came about because of general angst from some slave owners. These owners believed that there should not be any blacks fighting for the independence because they were only good for being slaves and they would never have say over anything. After some time Washington, fearing not having enough men to fight against the British, partially reversed this order to allow only free black men. Other than this there were not many consequences that are recorded for free black men. These free men not only fought for the independence of the nation but also for their independence and the independence of other black men and women. African-Americans from the north and south chose to join the continental army because they believed that they should help make the place the lived independent from a tyranny that had no say in the matters of a new country. They felt that this tyranny could take their rights and place them under unfair rule once again. Some of the freemen and slaves that had started out in the continental army decided to run to the British army but were not successful in their plights. Nash called the revolution the ‘greatest slave rebellion in American history’ because it was just that. The revolution opened up new grounds for slaves to rebel against owners because it was the most opportune time for them to do so. â€Å"If any group within America’s diversified people came close to answering John Adams’s plea that ‘we must all be soldiers,’ it was black Americans. No part of revolutionary society responded to the call for arms with anywhere near the enthusiasm of those who were black. Proportionate to their number, African American males— and some females— were more likely to join the fray than white Americans. † According to this excerpt from another one of Nash’s books, African-Americans were much more adept to answering the plea of John Adams. If there were more African-American fighters than white that meant that more black males were subject to put themselves in danger in order to gain freedom. They would rather have one day of freedom, not knowing if they would die in the next second, hour, or day, than be a slave for the rest of their lives. This is one of the reasons why Nash called the revolution the ‘greatest slave rebellion in American history’. â€Å"Desperate to fill the thinned ranks of its regiments, states offered freedom†¦ to serve during the continuance of the present war with Great Britain. Every black enlistee would be ‘immediately discharged from the service of his master or mistress, and be absolutely free, as if he had never been encumbered with any kind of servitude or slavery. † If states were desperate to have more men come into their ranks then there was nothing really stopping slaves from escaping their masters and coming to fight. They all wanted freedom from someone. Slaves wanted freedom from their bonds that were tied to the soil they worked and the Americans wanted freedom from Great Britain. Both groups had their reasons to fight and the only way slaves knew how to become free was to rebel and run to an army. This was a time for large rebellions on all fronts not just from the slaves. It was a rebellion against the British from the former colonists and a rebellion against the men and women that were taken from their homes to somehow create new ones. â€Å"It may have been, as Nash says ‘the greatest slave rebellion in American history,’ but for most of the rebels it ended like the others, in death. Slaves who supported the American side fared better, but not much better. Only with great reluctance did Washington allow some to join his army. Other Virginians had another wartime use for them. In 1780 the state legislature offered salves as a bounty for enlistment in the war against British tyranny. The revolution did see enactment of measures for gradual emancipation in the northern states, but the number who benefited was small. † My view on the American Revolution has changed somewhat because of how the African-Americans were treated during and after the period of war. The Americans act as though they had not been fighting alongside each other and because of this withhold distaste for the blacks. The completely disregard the idea that every man is created equal and has certain unalienable rights. They do not extend these ideas that were written down on the Declaration of Independence to the free black Americans. Men that had fought with and under Washington were not looked as the same because the color of their skin and were not given the same rights. Because of how they were treated I see the Revolution more as a war against Britain to save other whites from tyranny rather than to gain independence for all mankind. ——————————————–. [ 1 ]. Gary B.

Second Conjugation Italian Verbs - Conjugating Italian Ere Verbs

The infinitives of all regular verbs in Italian end in –are, –ere, or –ire and are referred to as first, second, or third conjugation verbs, respectively. In English the infinitive (linfinito) consists of to verb. amare to love  Ã‚  Ã‚  temere to fear  Ã‚  Ã‚  sentire to hear Verbs with infinitives ending in –ere are called second conjugation, or –ere, verbs. The present tense of a regular –ere verb is formed by dropping the infinitive ending –ere and adding the appropriate endings to the resulting stem. There is a different ending for each person. Characteristics of the Second Conjugation The  «passato remoto » (historical past) of the second conjugation verbs has two diverse forms of the first and third person singular and third person plural:io temetti/temeiegli temette/temà ©essi temettero/temeronoio vendetti/vendeiegli vendette/vendà ©essi vendettero/venderonoNote! In standard usage the forms –etti, –ette, and –ettero are preferred. The majority of verbs whose root ends in t though, such as battere, potere, and riflettere, take the endings –ei, –à © and –erono.battereio batteiegli battà ©essi batteronopotereio poteiegli potà ©essi poteronoriflettereio rifletteiegli riflettà ©essi rifletteronoThe verbs fare and dire are considered second conjugation verbs (because they are derived from two third conjugation Latin verbs—facere and dicere) as well as all verbs ending in –arre (trarre), –orre (porre), and –urre (tradurre).Verbs ending in –cere (vincere), –gere (scorgere), or –scere (conoscere) have a particular phonetic rule. C, g, and sc of the root maintains the soft sound of the infinitive before the declinations that start with e or i. They take the hard sound before the declinations that begin with a or o:vinceretu vinciche egli vincaspargeretu spargiche egli spargaconosceretu conosciche egli conoscaconosciutocresceretu cresciche egli crescacresciutoMany irregular verbs ending in –cere (piacere, dispiace, giacere, nuocere, tacere) maintain the soft sound by inserting an i before declinations that begin with a or o; if the verb has a regular past participle ending in –uto, an i is also added:nuocereio nuocciotu nuociessi nuocciononuociutopiacereio piacciotu piaciessi piaccionopiaciutogiacereio giacciotu giaciessi giaccionogiaciutoVerbs ending in –gnere are regular and maintain the i of the declinations iamo (indicative and present subjunctive) and iate (present subjunctive):spegnerenoi spegniamoche voi spegniateVerbs endi ng in –iere drop the i of the root before declinations that start with i:compieretu compinoi compiamo
