In these few chapters that we read, we have already learned a lot about Okonkwo, his life, and how he shows sympathy to some, but to others he is heartless. Okonkwo is other wise known as an unsympathetic person. Okonkwo is a clan leader of umuofia who holds many titles and is well known among his people. Okonkwo's daily life consists of tending to the three yam farms he has produced and to make numerous offerings to numerous gods and to help himself and his family. Okonkwo's personality is hard driven, since his father did not provide for him and his family Okonkwo had to start man hood early and this led him to be very successful in his adulthood, Okonkwo is an unsympathetic character who only shows sympathy rarely because he believes it's a sign of weakness Okonkwo's family relationships make him a sympathetic character because when his children show signs of manliness or do their jobs right he shows sympathy towards them. He is an unsympathetic character because whenever he get a little mad he has to take his anger out on something and that is usually vented by beating his wife's.
In Achebe’s Things Fall Apart, Okonkwo is an extremely complex character who experiences a variety of emotions which he has a difficult time controlling. He experiences a never ending battle of psychosomatic symptoms, starting with his obsession over the conflict of the past with his father, Unoka. Okonkwo portrays himself as a heroic, strong warrior, only to mask the feelings of intense anger, fear, and selfishness that provokes him, which inevitably leads him down the same path as his father. He feels a strong hatred towards his father because he believes that his father had no masculine qualities, he owed everyone money, and owned no titles. Achebe states:
Okonkwo’s father Unoka “was lazy and improvident was quite incapable of thinking about tomorrow.” Unoka owed everybody money and whenever he had money he would spend it on palm- wine. “He was poor and his wife and children had barely enough to eat.” Okonkwo was very ashamed of his father when he died because he not taken any titles and he was heavily in dept. Okonkwo did not want to be like his father so he worked very hard and at a young age he was a wealthy farmer and had two barns full of yams, and he had married his third wife. Not only that but he had two titles. This was a very tough task but Okonkwo managed to do it and the villages looked up to him.

Though these morphological changes have been known for some time, very little is known about the mechanisms underlying them. The processes that govern cell cycle regulation are of great interest to researchers, as aberrations like improper chromosome segregation and nonfunctional microtubule assembly can result in apoptosis or, if the cell doesn’t undergo apoptosis, cancer. Most evidence surrounding cell cycle regulation comes from studies on embryonic development of amphibians. Amphibian eggs contain many of the proteins required to carry out mitosis, but can only enter mitosis after fertilization. In addition to these proteins, the eggs contain a v...
Microvilli and cilia play a major role in many important biological processes in mammalian cells. They are very small, intricate structures found lining the cells in the body and can only be viewed under a microscope. Microvilli has been derived from the Greek word mikros, meaning “small” and the Latin word villus, meaning “hair”. Cilia means “eyelashes” in Latin(1). They are both types of projections in the plasma membrane, however, only cilia can move(2).
The repetitiveness of the winding of both cilia and flagella provide adequate, constant motility for all types of cells (Lindermann & Lesich 2010, p. 519). These organelles are ‘cellular appendages composed of specialised microtubules’ encased in an extension of a plasma membrane (Linck 2009, p. 1). The core of microtubules has remained unaltered throughout evolution since its origins. Cilia and flagella elongate from a basal body, which itself contains nine microtubule triplets, surrounding a cartwheel that operate as a basis for the assembly of the core structure (Vincensini, Bliscnick & Bastin 2012, p. 109). This core structure (called axoneme) within motile cilia and flagella, consists the typical “9+2” arrangement where nine microtubule doublets are constructed as an outside ring and two microtubule singlets centred within the doublets (Linck 2009, p. 1). Alternatively, the “9+0” axoneme present in primary cilia do not have sets of dynein arms (Vincensini, Bliscnick & Bastin 2012, p. 109). According to Linck (2010, pg. 3), ‘basal bodi...
The purpose of this lab is to observe and discern the properties of two items that we viewed under a microscope. Amongst the criteria we are looking for, we want to find out if the items are living, what makes them living.

At the beginning of the novel Okonkwo was a fairly wealthy and well-respected member of the Igbo society, but it had not always been that way for him. Okonkwo?s father, Unoka, had been a lazy man who would rather play his flute than take care of his crops. Unoka was said to be a charming man, and was able to borrow large amounts of money from his friends, but was never able to pay it back. As a result, Okonkwo has grown up very poor and ashamed of his lazy father. At one point in the book, Okonkwo remembers hearing one of his playmates calling his father an ?agbala,? which was the word for woman, but all described a man who had taken not titles (13). Okonkwo never forgets this, and actually develops a deep-seated fear that people will think that he is weak like his father. As I mentioned, Okonkwo became very well known, and his wealth and prestige rested solely on his own personal achievements. Okonkwo had received no inheritance from his poor father, no land and no money. As a young man, Okonkwo had been very successful wrestler, and as he grew older he became a well-known warrior. He was said to have brought home five human heads, which was a great achievement even for men who were much older that he was. At the beginning of the story, Okonkwo had obtained two titles, and had the respect of every man from all nine villages of Umuofia. Symbols of his wealth and prestige were his family and his compound. As I mentioned earlier, Okonwo had received no inheritance, and at the time of this story Okonkwo is still fairly young, and the fact that he had three wives, several children, and a very productive piece of land showed that Okonkwo was a very diligent worker. ?Okonkwo ruled his household with a heavy hand. His wives, especially...
Okonkwo is “a man of action, a man of war” (7) and a member of high status in the Igbo village. He holds the prominent position of village clansman due to the fact that he had “shown incredible prowess in two intertribal wars” (5). Okonkwo’s hard work had made him a “wealthy farmer” (5) and a recognized individual amongst the nine villages of Umuofia and beyond. Okonkwo’s tragic flaw isn’t that he was afraid of work, but rather his fear of weakness and failure which stems from his father’s, Unoka, unproductive life and disgraceful death. “Perhaps down in his heart Okonkwo was not a cruel man. But his whole life was dominated by fear, the fear of failure and weakness….It was not external but lay deep within himself. It was the fear of himself, lest he should be found to resemble his father.” Okonkwo’s father was a lazy, carefree man whom had a reputation of being “poor and his wife and children had just barely enough to eat... they swore never to lend him any more money because he never paid back.” (5) Unoka had never taught Okonkwo what was right and wrong, and as a result Okonkwo had to interpret how to be a “good man”. Okonkwo’s self-interpretation leads him to conclude that a “good man” was someone who was the exact opposite of his father and therefore anything that his father did was weak and unnecessary.
Evolutionary developmental biology (evo-devo) was instituted in the early 1980s as a distinctive field of study to characterise the new synthesis of evolution hypothesis (Müller, 2007). Evo-devo is regarded as a new rule in evolutionary biology and a complement to neo-Darwinian theories. It has formed from the combination of molecular developmental biology and evolutionary molecular genetics; their integration has helped greatly to understand both of these fields. Evo-devo as a discipline has been exploring the role of the process of individual development and the changes in evolutionary phenotype, meaning the developmental procedure by which single-celled zygotes grow to be multicellular organisms. Alterations in the developmental program frequently cause differences in adult morphology. When these alterations are helpful, they grow to be fixed in a population and can result in the evolution of new phyla. Evo-devo seeks to figure out how new groups happen by understanding how the method of development has evolved in different lineages. In other word, evo-devo explains the interaction between phenotype and genotype (Hall, 2007). Explanation of morphological novelty of evolutionary origins is one of the middle challenges in current evolutionary biology, and is intertwined with energetic discussion regarding how to connect developmental biology to standard perspectives from the theory of evolution (Laubichler, 2010). A large amount of theoretical and experiential effort is being devoted to novelties that have challenged biologists for more than one hundred years, for instance, the basis of fins in fish, the fin-to-limb change and the evolution of feathers. The biology of development promises to formulate a main contribution to these...
The labium occupied the ventral region of the head. Both maxillae fuse together from their base with the labium and hypopharynx-maxillary complex to form the labial hypopharynx-maxillary complex (Fig.7). The labium is divided into three regions; prementum, mentum and submentum. The mentum is large and lightly sclerotized. The submentum consists of two triangular sclerites. The prementum carries the spinneret and the hypopharynx is covered with a large number of spines (Hps). The labium has a pair of labial palps (Lbp) and the spinneret (Sp) lies between the bases of these palps. The spinneret situated on flat triangular region appears as long tube-like. The spinneret role is releasing the silk secreted by the glands of larvae. The labial palp takes the form of a long cylindrical segment bearing one long styloconic sensillum (20.2 μm) and a short sensillum chaeticum (9.58 μm). The sensillum styloconicum has a cylindrical base and a spine-like apical portion. At the lateral side of the labium, two pairs of long chaetic sensilla (Cs1-Cs4) (66.31-71.76 μm) were observed in figure 8. Additionally, a pair of sensilla chaetica (Cs5-Cs6) at the base of labium (54.95 μm) was observed.
