Love and Neurobiology: Not So Strange Bedfellows :: Biology Essays Research Papers

Love and Neurobiology: Not So Strange Bedfellows "The moment you have in your heart this extraordinary thing called love and feel the depth, the delight, the ecstasy of it, you will discover that for you the world is transformed." -J. Krishnamurti Love is one of life's great mysteries. People live and build their lives around love. For many people, love, or the quest to find love, is a reason to get out of bed in the morning. Love is arguably the most overwhelming of all emotions. Many ideals and religions consider the bond of love sacred. But, why do people fall in love? Is romantic love an enigma, or can it be reduced to the presence of certain chemicals and neurotransmitters within the brain at a given time? In the hit movie Roxanne, Steve Martin plays an articulate, put-together fire chief. However, when he falls in love with Roxanne, he acts crazy and performs dangerous acrobatics on her balcony in an attempt to earn her love. In Titanic, the two lovebirds risk it all in a vein attempt to pursue their love. And, in Shakespeare's classic, Romeo and Juliet, the love struck Venetians deny their families and take their own lives in the name of love. What causes this temporary insanity that most everyone encounters at some point in his or her life? Many believe that love is spontaneous and inexplicable, however many neurobiologists disagree. They stand by the idea that the brain causes all behavior, even love. The scientific definition of love is "having stimulation that one desires" (5). Recent research by two British neurologists concludes that love is linked to certain brain activities. By conducting tests using a magnetic resonance imager, the scientists measured brain activity in 17 people while they were viewing a picture of their loved one, and while they were viewing a photo of a friend of the same sex as their lover. When the individuals see the picture of the person they love, clear activity occurs in four regions of the brain that were not active when the image of the friend was present. The media insula, which is responsible for instinctual feelings, and the anterior cingulate, which acts in response to euphoria-inducing drugs, such as cocaine, are the two areas of the cortex stimulated by pictures of a lover. The striatum, that is activated when we are rewarded and the prefrontal cortex also increase their activity when shown the same picture.

Graduation Speech: We are Blessed to Live in the USA :: Graduation Speech, Commencement Address

Dear fellow students, faculty, friends, and family, My name is Sam Myers and I'm from Albania. Coming here was a great experience for me. I grew up in a poor country where the chances to get a good education were extremely limited. I went to schools with broken windows, and did homework by candlelight because we had no power. I was raised in a simple family by parents who loved me dearly, cared for me, and taught me life values that I carry with me. I wish they were here today. My parents had no educational background and could barely read or write. I had nothing compared to what young people in America have. But my parents communicated to me the importance of a good education, and today I am graduating from Marefat Community College in the United States of America. What a huge difference! The fall of communism in Albania in 1990 brought Albanians hope for the future. As every young man, I had dreams and one of them was studying abroad. God brought me here in a miraculous way. While providing medical care for the Kosovo refugees during the war of 1999, I met the people who provided the financial support I needed to come to America. It was exciting and scary at the same time. I had lived all my life with my family in the same country, but it was time for big changes and new adventures. I cherish the wonderful feelings of my first days on the Marefat campus. The easy access of many resources on campus including the library, computer labs, and many others made my learning process easy. I have learned that the key to success is working hard and focusing on your goal. Despite the many distractions this country offered me, I reminded myself that I had a goal to reach and I was here for a specific purpose. Marefat Community College opened many new doors for my future. One of my greatest experiences was working at the Office of Student Life as a student programmer. I learned to work in a business environment, coordinating events and communicating with students and staff. Working as a team with students from different cultures and backgrounds opened my eyes to get a better picture of the world. For the first time in my life, I met people who did not look like me. As I got to know them, I was able to break the stereotypes I had built growing up in a country that was closed to the rest of the world for 50 years.

The Woman’s Renaissance

Did Women Participate In The Renaissance? Thesis: Women off higher social and economic status had a broader range of opportunities such as reading, writing, and art, but were still expected to do household chores, while women of a lower class were bound even more strictly to their domestic responsibilities. General Info Household chores came first (Cooking, cleaning, sewing, etc. If a woman did not array, she would enter a convent or live with relatives Women would never live alone or be economically self sufficient Applied to all social classes Upper Class More opportunities were available, but women were still very suppressed Mastered multiple languages, wrote, painted etc. Were still expected to do chores despite having servants Education was available but limited Patronized the arts when possible Middle/ Lower Class Chores/children came firstHad to work alongside their husbands at their Jobs Women were not allowed to be outspoken or express themselves in any way The only educatio n they received was on how to be a good wife and mother Examples Isabella detest (1474-1539) Italian renaissance woman Marguerite De Invader (1492-1549) wrote poetry and ruled Spain with her brother Francis I Catherine De Medici (1519-1589) Major political force, patron of the arts, well educated from a young age Topic Sentences 1.While upper class women had domestic duties, they were able to enjoy in a few limited opportunities like education and the arts. 2. The expectations for women of lower classes were primarily to serve traditional household roles, such as chores, rearing children, and often working with their husbands. 3. While upper class women had special opportunities, and lower class women had certain obligations, they both put household chores before any other luxuries or responsibilities.

Impact of Opec Essays

Impact of Opec Essays Impact of Opec Essay Impact of Opec Essay The Organization of the Petroleum Exporting Countries (OPEC), inter-governmental organization, was established at the Baghdad Conference in Iraq in September 1960 by Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela. These five countries were later joined by eight other countries; Qatar (1961), Indonesia (1962), Libya (1962), United Arab Emirates (1967), Algeria (1969), Nigeria (1971), Ecuador (1973), and Gabon (1975). Ecuador and Gabon withdrew from OPEC in 1992 and 1994. The current eleven OPEC members account for about 40 per cent of world oil production, and two-thirds of the world’s proven oil reserves. Note: Iraq remains a member of OPEC, but Iraq’s production has not been a part of OPEC quota since 1998). The purpose of OPEC is to co-ordinate and unifies petroleum policies among the member in order to limit supplies in the hope of keeping prices high. From 1920s to 1960s, the major oil companies colluded to prevent prices from falling. In th e 1960s, OPEC had started as a group of five oil producing, developing countries, seeking out the member countries’ legitimate rights in the international oil market. So the rise of OPEC was tied to a shifting balance of power from the multi-national oil companies to the oil producing countries. The creation of OPEC intensified the need among the Third World countries for closer cooperation in order to achieve their political and economic objectives. Membership grew to ten within the decade. In 1970’s, member countries took control of their domestic petroleum industries and acquired the right to influence the pricing of crude oil on the world market. There were two oil pricing crises, triggered by the Arab oil embargo in 1973 and the Iranian Revolution in 1979. During the 1973 War between Egypt and Israel, Saudi Arabia refused to increase production in order to halt rising prices unless the United States backed the Arab position. When the U. S. government proposed a military aid package for Israel, Arab States began an oil embargo against the United States and later expanded to the Portugal, South Africa, and Netherlands. The first Summit of OPEC sovereigns and Heads of State was held in Algiers in 1975. OPEC acquired its 11th and final current member, Nigeria, in 1971. In 1980s, oil prices peaked at the early period in the decade. Iranian Revolution and ensuing stop of Iranian petroleum exports had caused panic and speculation in the world oil market. This is called Second Oil Shock. Moreover, the outbreak of the war between Iran and Iraq in 1980 affected the oil market. The Iran-Iraq war removed almost 4 million barrels of oil a day from the world market. Since early 1980s, the world petroleum market confronted OPEC with an unfavorable choice such as cutting price to regain market or cutting production to maintain price. But OPEC did not want to reduce oil prices; for fear that they would loose economic and political gains, and their political influence. Environmental issues began to be discussed as an international agenda In the early 1990s, OPEC experienced a third price crisis when Iraq invaded OPEC member Kuwait. Iraq had long claimed the territory of Kuwait. In 1991 the territorial conflict was worsen by the oil issues. One of them was the continued pumping of oil by Kuwait from a field located under both countries and another issue was low oil revenues for Iraq which made playing off its war debts difficult. Iraqi invasion would expand revenues. Iraqi power in OPEC raised oil price and increases war debts to Kuwait. Iraq thought that the United State response would be political and economic sanction. But the Iraqi invasion causes a military response which was supported by a coalition of western and Arab states. The absence of the two major oil producers (Iraq and Kuwait), could have raised the oil price to ceiling. Meanwhile, Saudi Arabia and other oil producers expanded production to keep prices from raising a great deal. Since the Persian Gulf War, Iraq has refused to compliant with the United Nations resolutions; in other words, Iraq invasion has resulted in a long term oil embargo. During the 1990s, OPEC continued to emphasize oil production quotas. Oil prices collapsed at the end of the period, but began to increase in the beginning of 21st century, owing to the greater unification of OPEC members and increasing the well-governed oil company in Non-OPEC countries such as (Mexico, Oman, Russia, and Norway), and also increased tensions in the Middle East, and political crises in Venezuela affected oil prices in the world. OPEC has attempted to develop a coherent environmental policy because the international efforts to reduce the oil consumption have been more significant in this century. Economic Impact of OPEC: Our economy depends on its cost, of which a large part is represented by the cost of energy. The cost of the oil products is affected by the price of crude oil, taxation and other causes. The price of crude oil is influenced by the decisions taken by oil producers, especially the price for which they are willing to sell. Oil prices obviously matter to the world economy and OPEC still has influence on oil price decision. Higher oil prices since 1999 was partly caused by OPEC mal-management of oil supply. We can see that OPEC has influence on global economy, because oil prices remain an important determinant of economic performance of each county. If there is a shortage of oil supplies, oil price will rise. This would have all sorts of implications for industry, such as higher transportation costs. Higher costs can lead to lower economic growth. U. S. oil prices began to increase in the early 1970s when OPEC began to assume a major influence on oil prices. In 1970, OPEC members agreed to set an oil export tax rate of 55 percent, and OPEC members started to nationalize the oil industry. In 1973, Arab’s embargo resulted in that crude oil prices increased from average of $4. 15 per barrel in 1973 to $9. 07 in 1974, which led to the United States recession in 1974. In the late 1970’s, during the Iranian Revolution, declination of oil production led huge price increases. U. S. crude oil prices increased from $12. 46 per barrel in 1978 to $35. 24 in 1981. OPEC had huge impact on the economic industries. In term of oil price development, the cost of crude oil for U. S. refiners was $20 in 1996. Oil prices dropped a little in 1997; the cost fell to $12. 04 per barrel. Countries benefited from the lower cost of virtually oil products. Concerning this issue, OPEC member countries agreed to cut production, and OPEC tried to maintain the crude oil price above U. S. refiner cost in 1999. The production cuts pushed crude oil price up, hitting $30 per barrel in 2000. The production, however, started to increase, because OPEC tried to maintain market stability. Economic impact of OPEC has declined in the decades. The United States and other economies are less dependent on oil than they were 20 years ago. Because U. S. and other nation’s economies produces much more national output for each barrel of oil consumed compare to when they produced before. In 1970s, the U. S. economy generated about $250,000 of national output based on per barrel of oil consumed, but in 1999, economy produced about $450. 000 per barrel. This date shows the improved performance of the U. S. economy based on per barrel of oil consumed. Efficiency improvements, seeking out other energy sources have lessened the dependence of the U. S. economy on oil. Another data shows the declination of economic impact of OPEC, the U. S. economy spent more than 6 percent of GDP in crude oil in 1980 and 1981, when average price of crude oil was $28 a barrel. In 1996 to 1997, the price was $20 per barrel. But the percent of GDP spent on crude oil is less than 2 percent and 1 percent in 1998. These data indicates that oil price increases has less influenced the economy than they had in 1980s. Power of Saudi Arabia: Saudi Arabia’s economy heavily dependent on oil with export oil revenues accounting around 90 percent of total Saudi export earning, 70 percent of state revenues and 40 percent of the its GDP. Saudi Arabia holds the world’s largest petroleum reserves and accounts over one-third and one-half of total OPEC oil production. Saudi Arabia’s oil policy has huge influence world oil pricing. Three basics of its policy are; maintaining stability in oil markets; opposing high oil prices that might discourage demand growth or lead to a rapid rise in Non-OPEC production; maintaining its own dominant market share in the United States. Saudi Arabia has dominated the world oil market by emphasizing the market control and avoiding the new competition and maintaining the higher prices. It is true that the policy has worked well. Saudi Arabia is considered as a dominant firm while many other OPEC countries are price-takers. One thing with the problem that Saudi Arabia is a dominant firm is that its share of OPEC production rose from 24 percent in 1973 to 37 percent in 1980. So Saudi Arabia is in a better situation than other exporters. Within a considerable range of market conditions, Saudi Arabia could stabilize prices by restricting its own production and exports. Saudi Arabia also has a great ability to expand its production, and has wide political influence that reinforces the power that it derives from being the largest exporters of oil. In 1999, Saudi Arabia took a key role in coordinating campaign of OPEC and other oil-producing countries to raise the oil price to its highest level since the Gulf War by managing production and oil supply. Moreover, Saudi Arabia established the Supreme Economic Council to formulate and coordinate economic development policies for institutional reforms. Relationship to Non-OPEC Countries and Prospects: OPEC and Non OPEC countries often agree to reduce oil and gas supply to check prices. This cooperation is rather strange but since both organizations often benefit from high oil price, then each organization may be obliged to cut or increase oil production at the request of the other countries. So oil price is decided based on demand and supply to maximize the profit of producing of OPEC and Non-OPEC. OPEC supplies 40 percent to 45 percent of world’s oil supply and holds 75 percent of proven revenues and Non-OPEC countries produce 60 percent of the world oil (est. 2004). Most Non-OPEC countries have private sectors; there is little government intervention over production level. Non-OPEC productions were more vulnerable to price collapse because Non-OPEC countries’ production costs tend to be higher than OPEC costs. The production of Non-OPEC countries has declined in decades, and OPEC may be more important role to decide oil prices. However, OPEC has actual influence on price, but does not control or set the oil price directly. The world oil market itself appears to be in change of pricing and in a long term the main deciding factor will be substantially of OPEC revenues. The problem of capacity and depletion will be more significant. When oil price increases, countries start to produce more and undersell each other. The question arises as to how efficiently OPEC can implement the long –term strategy? Needless to say, we are faced with the problem â€Å"increasing demand and decreasing supply† in the world oil market. Reduction of oil production in Non-OPEC is also a burden to OPEC. OPEC member countries are aware of growing international need of renewable energy and environmental problems due to use of fossil fuels. But there is no specific alternative energy supply in the near future and there is no significant regulation to control energy consumption in the market based economy. How many people feel it an emergency? How many people know that the United State has refused to sign the Kyoto Protocol? It will not take long before our demand completely exceeds the production capability of the oil countries.

How to End Racial Segregation in the American Church

How to End Racial Segregation in the American Church One of Martin Luther Kings most famous quotes concerns racial segregation and the American church. It is appalling that the most segregated hour of Christian America is 11 oclock on Sunday morning†¦, King remarked in 1963. Sadly, more than 50 years later, the church remains overwhelmingly racially divided. Only between 5% to 7.5% of churches in the U.S. are considered to be racially diverse, a designation meaning that at least 20% of a churchs members dont belong to the predominant racial group there: Ninety percent of African-American Christians worship in all-black churches. Ninety percent of white American Christians worship in all-white churches, noted Chris Rice, coauthor of More Than Equals: Racial Healing for the Sake of the Gospel. †¦Years since the incredible victories of the civil rights movement, we continue to live in the trajectory of racial fragmentation. The biggest problem is that we dont see that as a problem. The racial reconciliation movement of the 1990s, which sought to heal racial divides in the church, inspired religious institutions in America to make diversity a priority. The popularity of so-called megachurches, houses of worship with membership in the thousands, have also contributed to diversifying U.S. churches. According to Michael Emerson, a specialist on race and faith at Rice University, the proportion of American churches with 20% or more minority participation has languished at about 7.5% for nearly a decade, Time magazine reports. Megachurches, on the other hand, have quadrupled its minority membershipfrom 6% in 1998 to 25% in 2007. So, how were these churches able to become more diverse, in spite of the churchs long history of racial divides? Church leaders and members, alike, can help to ensure that members of all backgrounds attend their house of worship. Everything from where a church serves to what kind of music it features during worship can influence its racial makeup. Music Can Draw in a Diverse Group of Followers What kind of worship music is featured regularly at your church? Traditional hymns? Gospel? Christian rock? If diversity is your goal, consider talking to your church leaders about mixing up the type of music played during worship. People of different racial groups will likely feel more comfortable attending an interracial church if the worship music theyre accustomed to is featured on occasion. To sate the needs of his culturally diverse membership of blacks, whites, and Latinos, the Rev. Rodney Woo of Wilcrest Baptist Church in Houston offers both gospel and traditional music during worship, he explained to CNN. Serving in Diverse Locations Can Attract Diverse Worshippers All churches engage in service activities of some sort. Where does your church volunteer and which groups does it serve? Often, the people served by a church share different ethnic or socioeconomic backgrounds from the church members themselves. Consider diversifying your church by inviting the recipients of church outreach to a worship service. Try to launch service projects in a variety of communities, including those where different languages are spoken. Some churches have launched worship services in the neighborhoods where they do outreach, making it easier for those they serve to participate in church. Moreover, staffers at some churches have even chosen to live in disadvantaged communities, so they can reach out to the needy and include them in church activities consistently. Launch a Foreign Language Ministry One way to combat racial segregation in church is to launch foreign language ministries. If church staffers or active members speak one or more foreign languages fluently, consider using their skills to launch a foreign language or bilingual worship service. A major reason Christians from immigrant backgrounds attend racially homogenous churches is that they arent fluent enough in English to understand the sermons delivered at a church not specifically designed for people from their ethnic group. Accordingly, many churches seeking to become interracial are launching ministries in different languages to reach out to immigrants. Diversify Your Staff If someone whod never visited your church were to check out its Web site or read a church brochure, who would they see? Are the senior pastor and associate pastors all from the same racial background? What about the Sunday school teacher or the head of the womens ministry? If the church leadership isnt diverse, why would you expect worshippers from diverse backgrounds to attend services there? No one wants to feel like an outsider, least of all in a place as intimate as church can be. Moreover, when racial minorities attend church and see a fellow minority among its leaders, it suggests that the church has made a serious investment in cultural diversity. Understand the History of Segregation in the Church Churches today arent segregated simply because racial groups prefer to worship with their own kind, but because of  Jim Crows  legacy. When racial segregation was government sanctioned in the early 20th century, white Christians and Christians of color followed suit by worshipping separately as well. In fact, the reason the African Methodist Episcopal denomination came about was that black Christians were excluded from worshipping in white religious institutions. When the U.S. Supreme Court decided in  Brown v. Board of Education  that schools must desegregate, however, churches began to reevaluate segregated worship. According to a June 20, 1955, article in  Time, the Presbyterian Church was divided over the segregation issue, while Methodists and Catholics sometimes or frequently welcomed integration in church. Southern Baptists, on the other hand, assumed a pro-segregation stance. As for Episcopalians,  Time  reported in 1955, The Protestant Episcopal Church has a relatively liberal attitude toward integration. The North Georgia Convention recently declared that segregation on the basis of race alone is inconsistent with the principles of the Christian religion. In Atlanta, while services are segregated, white and Negro children are confirmed together, and whites and Negroes are granted equal votes in diocesan conferences. When trying to create a multiracial church, its important to acknowledge the past, as some Christians of color may not be enthusiastic about joining churches that once excluded them from membership. Wrapping Up Diversifying a church isnt easy. As religious institutions engage in racial reconciliation, racial tensions inevitably surface. Some racial groups may feel that theyre not being represented enough by a church, while other racial groups may feel that they are being attacked for having too much power. Chris Rice and Spencer Perkins address these issues in  More Than Equals, as does Christian film  The Second Chance. Take advantage of literature, film and other available media as you set out to tackle the challenges of the interracial church.

The History of the Human Management of Honey Bees

The History of the Human Management of Honey Bees The history of honey bees (or honeybees) and humans is a very old one. Honey bees (Apis mellifera) are an insect that has not exactly been domesticated: but humans have learned how to manage them, by providing them with hives so we can more easily steal the honey and wax from them. That, according to research published in 2015, happened in Anatolia at least as long ago as 8,500 years. But physical changes to bees that are kept are negligible from those that are not kept, and there are no specific breeds of bees that you could reliably identify as domesticated versus wild. Three distinct genetic subspecies of honey bees have been identified, however, in Africa, Eastern Europe, and Western Europe. Harpur and colleagues identified evidence that Apis mellifera originated in Africa and colonized Europe at least twice, producing the genetically distinct Eastern and Western species. Surprisingly, unlike most domesticated species, managed bees have a higher genetic diversity than their progenitors. (See Harpur et al. 2012) Honey Bee Benefits We are fond of the stinging Apis mellifera, of course, for its liquid honey. Honey is one of the most energy-dense foods in nature, consisting of a concentrated source of fructose and glucose containing approximately 80-95% sugar. Honey contains trace amounts of several essential vitamins and minerals and also can be used as a preservative. Wild honey, that is to say, collected from wild bees, contains relatively higher levels of protein, because the honey contains more bee larva and larva parts than kept bees. Honey and bee larva together are excellent sources of energy fat and protein. Beeswax, the substance created by bees to encase their larvae in combs, was and is used for binding, sealing and waterproofing, and fuel in lamps or as candles. The 6th millennium BC Greek Neolithic site of Dikili Tash contained evidence for the use of beeswax as a binding agent. New Kingdom Egyptians used beeswax for medicinal purposes as well as embalming and mummy wrapping. Chinese Bronze Age cultures used it in the lost-wax technique as early as 500 BC, and as candles by the Warring States Period (375-221 BC). Early Use of Honey The earliest documented use of honey dates to at least the Upper Paleolithic, some 25,000 years ago. The dangerous business of collecting honey from wild bees was accomplished then as today, by using a variety of methods, including smoking the hives to reduce the response of the guard bees. Upper Paleolithic rock art from Spain, India, Australia, and southern Africa all illustrate collecting honey. Altamira cave, in Cantabria, Spain, includes depictions of honeycombs, dated approximately 25,000 years ago. The Mesolithic Cueva de la Araà ±a rock shelter, in Valencia Spain, contains depictions of honey collection, bee swarms, and men climbing ladders to get to the bees, at ~10,000 years ago. Some scholars believe that collecting honey is much earlier than that  since our immediate cousins the primates regularly collect honey on their own. Crittendon has suggested that Lower Paleolithic Oldowan stone tools (2.5 mya) could have been used to split open beehives, and theres no reason that a self-respecting Australopithecine or early Homo could not have done that. Neolithic Bee Exploitation in Turkey A recent study (Roffet-Salque et al. 2015) reported discovering beeswax lipid residues within cooking vessels throughout the prehistoric world from Denmark to North Africa. The earliest examples, say researchers, come from Catalhoyuk and Cayonu Tepesi in Turkey, both dated to the 7th millennium BC. Those come from bowls which also contained mammalian animal fat. Further evidence at Catalhoyuk is the discovery of a honeycomb-like pattern painted on the wall. Roffet-Salque and colleagues report that according to their evidence, the practice became widespread in Eurasia by 5,000 cal BC; and that the most abundant evidence for honeybee exploitation by early farmers comes from the Balkan peninsula. Beekeeping Evidence Until the discovery of Tel Rehov, evidence for ancient beekeeping, however, was restricted to texts and wall paintings (and of course ethnohistoric and oral history records, see Si 2013). Pinning down when beekeeping began is thus somewhat difficult. The earliest evidence of that is documents dated to the Bronze Age Mediterranean. Minoan documents written in  Linear B  describe major honey stores, and based on documentary evidence, most other Bronze Age states, including Egypt, Sumer, Assyria, Babylonia, and the  Hittite kingdom  all had beekeeping operations. Talmudic laws from 6th century BC describe the rules of harvesting honey on the Sabbath and where the proper place was to put your hives relative to human houses. Tel Rehov The oldest large production facility for producing honey identified to date is from Iron Age Tel Rehov, in the Jordan Valley of northern Israel. At this site, a large facility of unfired clay cylinders contained the remains of honey bee drones, workers, pupae, and larvae. This apiary included an estimated 100-200 hives. Each hive had a small hole on one side for the bees to enter and exit, and a lid on the opposite side for the beekeepers to access the honeycomb. The hives were located on a small courtyard that was part of a larger architectural complex, destroyed between ~826-970 BC (calibrated). About 30 hives have been excavated to date. Scholars believe the bees are the Anatolian honey bee (Apis mellifera  anatoliaca), based on morphometric analyses. Currently, this bee is not local to the region.

Animal Assignment Example | Topics and Well Written Essays - 750 words

Animal - Assignment Example The Cycopus Bear is a hairy mammal, in the family of Ursidae. Its body is not large as the common bear. The male bear has brown grey hairy skin with a white strip on the rib sides along the stomach, the tip of the tail, ears and two ticks like white marks on the cheeks below the nose. The female Cycopus bear is dark grey and is more hairy compared to the male (( Hill & Gordon, Pg. 67). The Cycopus bear does not have horns. They have slightly a stocky leg that enables them to sometimes stand on the back two legs. Their paws have claw like nails. A mature Cycopus bear can weight to about 50 - 55 Kg. The lifespan of theses bear extends to even 45 years in a favorable habitant. Just like most mammals, the Cycopus bear gives birth to young ones, within a gestation period of 3 months, and feed their young ones by mammary glands (Kingsolver, 45). This mammal creature is a vertebra. Its body is proportional, with two fore limbs and two back limbs. Standing at a fairly flat ground, this animal will appear to be slightly slanting from the head backwards. This body formationtentatively assists the animal to stand and even walk at its back limps especially when tracing an enemy from a distance ( Hill & Gordon, Pg. 43). This kind of bear has a closed circulatory system, where blood flows in veins and arteries. It has four chambered heart, with all parts of the body connected to the circulatory system by veins, arteries and capillaries which assist in the transportation of blood and oxygen fort respiration.
