Smooth ER: Acts as a storage organelle and is important in the creation of steroids and the storage of steroids and ion Ribosome: where proteins are made. Golgi Bodies: The main function is to package and process proteins and sends it to other parts. They also make and secret mucus. Chromosomes: Chromosomes are made up of DNA and contains genes. Nucleous: is where ribosomes are made. They disappear from the egg cell during reproduction. Haploid Nucleus: This nucleus contains only half of the normal somatic number of chromosomes. Zona Pellucida: Also known as viteline membrane it protects the ooccytes, eggs and embryos. Supports the cell and controls entry into and out of cell. The cell membrane allows the sperm cell in. Follicular Cells: Provides nutrients to the developing ovum for growth and maturation. WHAT MAKES THE EGG CELL SPECIAL? The egg cell has no centrioles. The egg cell has a lot of mitochondria because It has a haploid nucleuses because when the egg cell joins.. It has a zona pellucid which act as a cell membrane for the egg cell.

Franz Kafka :: essays research papers

Franz Kafka was different, a man bent on portraying changes everywhere. Kafka was also a man consumed by death, consumed by the fact that he might eventually die. One man who was greatly affected by his fathers negligence of him, and a social deviance about him which held him back from interaction. Such a man was so afraid about what society thought of his writing, that he never widely published his works, and even asked a friend to burn all manuscripts. Not only was Kafka Jewish, he resented this fact. Once Kafka even stated that “Sometimes I’d like to stuff all Jews (myself included) into a drawer of a laundry basket-then open it to see if they’ve suffocated.'; As anyone can see, Kafka was enormously enticed by death, and the fact that he greatly disliked his own cultural status, and even his family. Even though, this man was one accompanied by great wisdom, which was shown in the writing of Metamorphosis. Kafka was a political genius who showed all his political beliefs through his one great work, Metamorphosis. All of the experiences in Kafka’s life are portrayed through Gregor, a person who wished he was dead at the end of Kafka’s words. Distant from the poor, meager, and mostly un-vivacious reality of life and it’s hardships stands one man, Gregor, a provider of financial resources for his family. Such a young man is making his way in society, and the world in general. Through Gregor’s successes, and his almost workaholic attitude, he has suffered into prospering. Prosperity is an awkward word, for it is one which not only describes a persons wealth, though also his downfalls. The great undoing of prosperity shows itself in Gregor as he becomes a monster, one created by Anti-Marxist society. Since Gregor’s is a society which eventually shuns him, and his great mind for one fact. A fact that I wish to prove, through gazing at the society created in Kafka’s mind. However, a fact that has worth in studying because of it’s multi-faceted grooves and perceptions of society. In taking a glance at Kafka’s complex society, one must also see his society as an extension of Gregor. A person must first look at the meaning of Gregor’s name in German, and its derivation into English. The name Gregor is closely associated to “Gregariously';, which refers to a sociable and jovial mindset.

Trademarks lost in computer crash

Among articles specifically related to fields of e-business and intellectual property that abound in the Internet I found one which I believe is very interesting and at the same time very indicative of possible legal issues that may arise in those fields.This is the article from The Royal Gazette titled â€Å"Trademarks lost in computer crash†. This article describes an accident which happened with the computerized Trademark Registry in Bermuda, which is an island Overseas Territory of the United Kingdom situated in the Atlantic Ocean with internal self-governance. What makes Bermuda special is that it is known as one of the most important offshore financial centers of the world.More specifically, the article in The Royal Gazette reports about the computer database crash which caused the loss of records about approximately half of the 37000 trademarks registered in Bermuda, discusses ensuing consequences of this mishap, and mentions some legal issues and troubles that arose fr om this apparently unexpected event.In general, one of the accents that the article makes is on the mess that accompanied the problems with the computer hardware and the corresponding suspension of activities in the large trademark sector of Bermuda.Interestingly, the author of the article pays attention also to the roots of the technical problem itself, and mentions facts which suggest an involvement of a human factor as one of the causes of the problem.Now, among legal business issues raised in the article we may identify the following ones. Firstly, since for a prolonged period of time registration of new trademarks was suspended and because the whole trademark sector wholly relies upon the Trademark Registry, lawyers who represented companies with trademarks registered in the Trademark Registry in Bermuda could not be sure that their intellectual property had been protected or that no conflicting marks or infringements on property would emerge after the manual recovery of the da tabase.At the same time, the article draws our attention to the fact that the computer crash, while being a gross embarrassment for Government which has been promoting Bermuda as a leading centre of e-business and intellectual property, also serves as an example of what types of encumbrances e-business may encounter from time to time.Indeed, if such an accident has happened once, it may happen as well in other countries, and as the author of the article points out that trademark sectors of for instance the United States and Britain is much larger, it is easy to imagine what mess could arise there in a similar situation.In this way, one of the main legal issues that e-business faces is the creation of additional legal mechanisms which, of course along with the increased protection of important and private data, would ensure protection of intellectual property even during such crisises as the one that happened in Bermuda, and, importantly, endow participants involved into e-business a nd therefore especially susceptible to negative consequences of problems akin to the one in Bermuda with a sense of security.On ground of this, we may conclude that legal issues affect business in direct and indirect ways. For example, the suspense of related business activities during the period of time needed for the manual restoration of the database had some concrete economic costs.On the other hand, even though the problem with the computerized Trademark Registry in Bermuda was solved in a relatively fast manner this accident surely had struck a blow to the image of Bermuda. Indeed, the problems could, and for that matter should, have been avoided in the first place by merely paying more attention to the maintenance of the hard discs with the stored information, and by making sure that back-up systems worked properly.And even though I think that it is unlikely that such a problem will reoccur in the future in Bermuda, I believe that the realistic solution for the Trademark Regi stry to make most use of this trouble is not only to strengthen their computer system, but to compensate to companies, which have trademarks registered in Bermuda and which experienced inconveniences caused by the loss of data, in both a direct way, and in an indirect manner by assuring them in an increased protection of security of their intellectual property in the future.SourcesBreen, S.
