The Evolution Of Human Animals - 1744 Words

Humans, formally known as Homo sapiens, are some of the most fascinating creatures to inhabit this planet. We as human animals possess many traits unique to our species, but one of the most remarkable traits is our upright posture and inherent inclination to walk on two legs. We share this rare trait with few organisms, who even so only express limited bipedal behaviors. Human ancestors first initiated the transition to bipedalism approximately 6 million years ago through the upright steps of the Sahelanthropus. However, Homo erectus was the first human ancestor to express full bipedality, which occurred only 1.9 million years ago. Some of the preceding forms of locomotion used by human ancestors included quadrupedalism or pronograde posture, suspensory locomotion, and knuckle-walking (Watson, 2008). These forms of motion were used not only by human ancestors such as the Australopithecus afarensis, but can also be observed in modern times in some of our close relatives, apes and chim panzees. This transition to bipedalism was facilitated by structural changes comprised of an angled thigh bone, a more sturdy and broad pelvis, a wider patella, an S-shaped spine, and long femurs. The compilation of all of these adaptations allowed hominids to not only support their entire body weight while standing upright, but efficiently take long strides, therefore allowing them to travel greater distances. Though much is known about the implications for the transition to bipedality, theShow MoreRelatedThe Truth About Life On Earth Essay1012 Words   |  5 PagesQuotes†).

Journey Of A Sperm Cell Samples for Students †MyAssignmenthelp.com

Question: Discuss about the Journey Of A Sperm Cell. Answer: Journey of a Sperm cell Sperm cells are formed in the scrotum. It is the scrotum that protects the testicles and helps to regulate the temperature of the testicles. The sperm travels up to the epididymis through the testes to the sperm duct and moves to the vas deferens then to the seminal vesicles. It is where the sperm cell is nourished and goes to the prostate gland. One last stop is made by the sperm cell at the cowpers gland in order to get rid of the acidity of urination. The sperm finally travels up the urethra and is ejaculated out of the penis. At the time of intercourse, the sperm is shooted in to the vagina, which is again a long tube like structure in the female body (Ikawa et al. 2010). It is where the sperm begins their next phase of the race of fertilizing the egg. Throughout the journey the spermatozoa has to cross a number of hurdles making it difficult to get through the fallopian tube and strike the egg. The sperm have to swim a distance of about 15 to 18 cm and it does not take too long to reach the egg once it has been released from the ovary. A spermatozoon is strong enough to remain viable for about 2-5 days inside the reproductive tract of the female. Along the length of the tube, the most powerful sperm, who have been able to overcome the obstacles of the female reproductive system such as the vaginal acidity, immune response, cervical mucus and other physical barriers gain an extraordinary fertilization capacity and the sperm tail becomes stronger and powerful to continue its journey with more energy and efficiency (Moore et al. 2011). The chosen sperm then goes through the acrosomal reaction, where the acrozomal enzyme of the acrozome present in the head of the sperm weakens the Zona Pellucida of the egg and breaks through it. As the sperm enters the egg, the nuclei fuse together and make the fertilization process successful. References Ikawa, M., Inoue, N., Benham, A.M. and Okabe, M., 2010.

Political Environment In International Marketing Essays

Political Environment In International Marketing THE POLITICAL ENVIRONMENT: The critical concern Political environment has a very important impact on every business operation no matter what its size, its area of operation. Whether the company is domestic, national, international, large or small political factors of the country it is located in will have an impact on it. And the most crucial & unavoidable realities of international business are that both host and home governments are integral partners. Reflected in its policies and attitudes toward business are a governments idea of how best to promote the national interest, considering its own resources and political philosophy. A government control's and restricts a company's activities by encouraging and offering support or by discouraging and banning or restricting its activities depending on the government. Here steps in international law. International law recognizes the right of nations to grant or withhold permission to do business within its political boundaries and control its citizens when it comes to conducting business. Thus, political environment of countries is a critical concern for the international marketer and he should examine the salient features of political features of global markets they plan to enter. THE SOVEREIGNITY OF NATIONS From the international laws point of view a sovereign state is independent and free from external control; enjoys full legal equality; governs its own territory; selects its own political, social, economic systems; and has the power to enter into agreements with other nations. It is extension of national laws beyond a country's borders that much of the conflict in international business arises. Nations can and do abridge specific aspects of their sovereign rights in order to coexist with other countries. Like the European Union, North American Free Trade Agreement (NAFTA) are examples of nations voluntarily agreeing to give up some of their sovereign rights in order to participate with member nations for common, mutually beneficial goals. For example the pajama game discussed in global perspective is not unusual for multinational corporations. The pajama caper was a controversy arose over a US embargo forbidding US businesses to trade with Cuba. Wal-Mart was selling Cuban made pajamas in Canadian market. When Wal-Mart officials in US came to know about this, they ordered all offending Cuban pajama's as it was against US law. Canada was incensed with the obtrusion of US law on Canadian citizens. The Canadian citizen's felt that they should be able to buy Cuban-made pajama's if they wanted to. Wal-Mart was caught between a Canada-US foreign policy feud. Wal-Mart Canada was breaking US law if it continued to sell pajamas, and was subject to a million-dollar fine and possible imprisonment. However, if it did pull out pajamas from Canadian market it was subject to 1.2 million dollar fine under Canadian law. The ideal political climate for a multinational firm is stable, friendly environment. Unfortunately, that is never really the case, it's not always friendly and stable. Since foreign businesses are judged by standards as variable as there are nations, the friendliness and stability of the government in each country must be assessed as an ongoing business practice. STABILITY OF GOVERNMENT POLICIES The most important of the political conditions that concern an international business is the stability or instability of the prevailing government policies. Political parties may change or get reelected but the main concern for MNCs is the continuity of the set rules or code of behavior regardless of the party in power. A change in the government does not always mean change in the level of political risks. In Italy the political parties have changed 50 times since the end of World War II but the business continues to go on as usual inspite of the political turmoil. In comparison is India, where the government has changed 51 times since 1945 but however much of the government policies remain hostile to foreign investments. Conversely, radical changes in policies toward foreign business can occur in the most stable of the governments. Some of the African countries are among the unstable with seemingly unending civil wars, boundary disputes and oppressive military regimes. Like one of the region with the greatest number of questions concerning long-term stability is Hong Kong as since China has gained control, the official message is that nothing will change
