The roles water in living organisms and water as a habitat for organisms
The roles water in living organisms and water as a habitat for organisms Introduction Water is the most abundant liquid on the planet. It covers 2/3rds of the earth's surface, and at least 60% of living organisms is water. This value may be as large as 99% - in a jellyfish. The reason for such a large amount of water making up organisms is the fact that it is a major cell constituent - more on that later. Water is a simple molecule yet has many interesting properties which contribute to its importance. Structure The molecule is polar, because the electrons in the bonds between O and H are pulled slightly toward the O. this means that the O atom is slightly negative and the two H atoms are slightly positive (shown by ?+ and ?-). The electrons are shown as small dots; note they are closer to the O. These properties are described more in the solvent section. db. Water is made up of two hydrogen atoms bonded to one oxygen atom. They are covalently bonded and the intramolecular covalent bonds are very strong. The structure is non-linear, due to the electron pair repulsion of the two lone pairs of electrons on the oxygen atom. Major cell constituent Often 2/3rds or more of living cells are water. The water is found mainly in the cytoplasm, and it plays a vital role in many functions of the cell: in all organisms - metabolism, and in plants photosynthesis and support. The
The Psychodynamic Approach.
The Psychodynamic Approach The first man who began to study the Psychodynamic Approach was Sigmund Freud. When you talk about the Psychodynamic approach you can consider it as focusing on the role of internal process in shaping personality. As Robinson (1979) stated, concerns about motivation are always linked together with the psychology of personality. According to this, psychoanalysis is both a theory of motivation and a theory of personality. However, who was this Freud and what did he do to be this famous? Sigmund Freud (1856-1939) was born in Moravia in the Czech Public. He lived in a middle class family and was the eldest of eight children. He studied in Vienna and most of his life he spent in this town. Later on he became a doctor and during that time he learned about hysteria disorders and techniques of hypnosis. These two were to play a big role in his career. Soon he became more specialized in neurological disorders and became a leading figure in the area. Freud became famous for his writings on psychoanalysis. In 1919 he granted the title of professor at the University of Vienna. Later on in his life he underwent a series of surgeries for cancer in the jaw. He died in London in 1939 at an age of eighty-three. Freud has become one of the most famous psychologists of all time. One of Freud's most fundamental assumptions, Physic determinism, was partially based
The Psychodynamic Perspective.
The Psychodynamic Perspective. One of the key beliefs of the psychodynamic approach is that our adult personality and behaviour are determined by our childhood experiences. Sigmund Freud chiefly initiated this approach. Although Freud continually revised many of his theories, three of them remained constant. These were; firstly, that a vast majority (about 6/7) of the mind is unconscious and contains our instincts, drives and repressed memories. The only ways to discover the contents of the unconscious mind are dream analysis, word association and hypnosis. Secondly, that the mind is made up of three parts, the ID, the EGO and the SUPEREGO. The ID works on the pleasure principle. It contains the psychic energy of all our drives, instincts and repressed memories; it requires immediate satisfaction without any regard for reality. It was referred to by Freud as, 'a cauldron of seething excitations' (cited in Hill 2001, pg 73). The EGO works on the reality principle. It aims to fulfil the ID's desires whilst keeping them in line with what is possible in the real world. The SUPEREGO pressures the EGO to keep the ID in line with moral ideology. It sets ideals and consists of the conscience, which makes us feel things such as pride and guilt. To enable the EGO to deal with the demands of the ID and SUPEREGO, it uses a number of defence mechanisms. Some of these are
"Who is the Real Monster in Frankenstein, Victor or his Creation?"
"Who is the Real Monster in Frankenstein, Victor or his Creation?" Mary Shelley wrote the novel Frankenstein in the early part of the nineteenth century. The novel was written at a time when Mary Shelley and her husband Percy were staying at the home of Lord Byron on the shores of Lake Geneva. Mary Shelley was born in 1797, her mother died shortly after her birth. As a child the idea of republicanism was implanted into her by her father. Her mother had been an early women's rights campaigner and had written several books on the subject. Her father, on the other hand, was very interested in alchemy and Galvanism. Galvanism was the idea of running electric currents through a body to restore it to life, invented by Luigi Galvani. In Frankenstein we are told of a man who creates a life. This creation is perceived by society and his creator to be a monster. Mary Shelly's Frankenstein explores a wide variety of themes, and raises some serious ethical issues. One such issue that comes up time and time again is that of who the real monster is, but what is a monster? The word monster can be described as behaviour crossing the boundaries of acceptability or seeking knowledge which should remain a mystery. For example in the novel Victors curiosity to follow ambitions no matter what the consequence. Stereotypically monsters appear ugly or abnormal. Over time the meaning of the word

The Supernatural in "Macbeth"
Macbeth Supernatural, no matter if you believe in it or not it still attracts the audience's heart. In the time of William Shakespeare there was a strong belief in the existence of the supernatural. Thus, the supernatural is s recurring aspect in many of Mr. Shakespeare's plays. In "Macbeth", the supernatural is an integral part of the structure of the plot. Not only do witches appear but also a floating dagger transforms into reality. Shakespeare intelligently introduced the elements of the supernatural in Act 1, Scene 3. Shakespeare located his scene in a mysterious marshy, deserted "heath" on a day with "thunder", perfect for paranormal activity. Thunder and lightning was believed to be associated with evil, and when the play was presented in Shakespeare's time, cannonballs would be rolled to create the sound effect. Three characters are introduced; immediately we knew that they are involved with the supernatural because the second witch told the others that she was "killing swine". Witches tried to hide from humans in fear of being burned at stakes, so they had to be in an empty heath to meet Macbeth. Back in the day, witches were blamed for the death of animals. Also, the witches repeated phrases three times. "I'll do, I'll do, I'll do" and instead of any other number of witches, there were three of them. The number three was regarded as a magic number. The
Was The Treaty Of Versailles Justified?
Was The Treaty Of Versailles Justified? The Treaty Of Versailles was an agreement between 32 nations deciding the fate of Germany. It was needed badly as war torn Europe was in turmoil. France had been devastated by the effects of war and sought to cripple Germany. The British Prime Minister, Lloyd George, realised the severe implications that this could have and so wanted a more lenient peace treaty. The American public had little interest in Post War Europe but their President, Woodrow Wilson, wanted a Germany that would make a good neighbour in Europe, hence his fourteen points. To reach a compromise a meeting was needed at the small palace of Versailles, not far from the French capital, Paris. Here the leaders of 'The Big Four', Orlando, Clemenceau, Wilson and George, representing Italy, France, Britain and America respectively, tried to find a lasting peace for Europe. This meeting was intended to bring stability ad peace into a crippled Europe. The date set was June 28th, 1919 and the members of 32 nations met up, in a council of 10, to agree on terms of peace for Germany, however none of the defeated nations were present at this meeting including Russia whose Government was not acknowledged by the Allies. The treaty was to last for 12 months and was to be a long and arduous task, even impeding Wilson's health, but what was the outcome and was the treaty justified?
