Observing Mitosis

Lab Report ?3 Title:Observing Mitosis By Yerkebulan Yesbolatov Biology course, tutorial group I October 18, 2012 Lab partner: Azhar Zhaisanova Introduction Experiment is intend to show mitotic stage of cell cycle, phases of mitotic stage, to define predominance in the number of each phases over the others, if it is possible. Objectivity of lab is to observe the different phases of mitotic stage of cell cycle, to get skills for special technique( by using orcein ethanoic stain) designed for making slide enable to observe mitotic stage of cell cycle.The tip of Garlic bulb’s root is suspected to be relevant for that, for observing the cell cycle. Aim To observe cell cycle in definite stage-in this experiment mitosis. To get knowledge of which phase is predominate in cell cycle. Precautions During the procedure it is need to wear eye protection cause hydrochloric acid is irritant It is necessary to wear gloves and coat – Toluidine blue is had ability to ingrain. Don’ t ingest- it is harmful. It is necessary to wear goggles and avoiding of content with orsein ethanoic stain, cause it corrosive, irritant, causing burns, has ability to irritate by vapour. Also read: What Algae Does a Trypanosome Superficially ResembleIn case of making contact immediately necessary to wash with water for 10 minutes. It is necessary to wear eye protection and avoid a skin contact, cause Acetic alcohol is corrosive and highly flammable Methods and Materials First method of staining is cancelled. Second method with 1-st step was provided in advance. First, several root tips was cut off, added to watch glass with acetic alcohol(2cm3) for 10 minutes. Then, specimens transferred to second glass, which contain 5cm3 ice cold water,4-5 minutes are needed to wait after that. Later on specimens, dried off with filter paper.Next step, in order to haven’t damage a specimen ,it was poured with pre-heated hydrochloric acid rather than putting the pattern to test tube and vice versa till 5 minutes. Next step is to repeat step with acetic acid (2cm3) for 10 minutes in a watch glass. After 10 minutes, specimen (one of several) was put to glass slide then poured w ith 1-2 drops of stain called acetic orcein stain, it should cover whole surface of pattern. Note that to stain the wall would be better to leave specimen in a dye more than 2 minutes. Finally, specimen is covered with coverslip and pushed under the filter paper, put to microscope and observed. ResultQuestion 1 is in separate page Question 2 Number of cells viewed under visible area x400. 43 cells 43Ãâ€"4=172 Table of numbers of cells at field of view Total number of cells| Names of mitosis phases| ? in each stage| 172| Interphase| 138| | Prophase| 28| | Metophase| 3| | Anaphase| 2| | Telephase| 1| Question 3. Percentage in each stage of mitosis Interphase =138172Ãâ€"100%= 80. 232% Prophase =28172Ãâ€"100%=16. 279% Metophase =3172Ãâ€"100%=1. 744% Anaphase =2172Ãâ€"100%=1. 162% Telephase =1172Ãâ€"100%=0. 581% Ranking of stages of cell cycle Interpase>prophase>metaphase>anaphase>telephase As it said, preparation freezed at one time.Most of cells, about 90% of cell and consequentl y 90% cycle cell spent in interphase, it is proved by findings. Roughly 20 percent, approximately quarter of interphase are taken by prophase, metaphase, anaphase, telephase. Question 4 Mitotic index Mitotic index=28+3+2+1172=34172= 0. 197 Mitotic index enable to find a tendency to grow of cells. It is mean that how cell is divide, at which rate it is reproduces. Question 5 Reliability and validity If centromeres of chromosomes are draw up at equator, we definitely could say it is metaphase, if we see sister chromatids at inverse poles we could say definitely say as it anaphase.A lot of cells are there with round nucleuses that is why it is – prophases. Telephase is differ by starting of dividing of cells. In interphase cells are as they are swallowed, e. c become bigger. Question 6 Safety precautions Wear goggles to avoid contact with orsein ethanoic stain is corrosive, has ability to irritate by vapour Wear gloves – acetic alcohol is corrosive and highly flammable. Q uestion 7 Treatment with hydrochloric acid It enable to stain the specimen of root tip. It can help to break the hydrogen bonds contain in it. Question 8 Reason Cells are in phase of telephase of mitosis or meiosis stage could start.Discussion There was cells with purple chromosomes on a pink background. There was drawn the each phases of mitosis to make easier the differentiation of phases cause is sometimes difficult to differ. At the beginning, when final stage of slide preparation was done, there was problem, three times with its observing-the image wasn’t enough pure to see a cells in mitosis stage. Cause could be wrong decay of specimen during the pressing. It should be taken into care that pressing of stained specimen should be strong to make image more clear and transparent. To define the number of cells visible t point of view (image which enable objective to see during reviewing without changing the position) of microscope it was calculated the quarter of circle row by row cause cells are not same, so rows are not same. Defining of microscope’s point of view is necessary for further calculating the percentage of each phase of mitosis. So, quarter of visible cells was equal to 43. These cells was multiplied to four. To tell every phase of mitosis:138 of interphases,28 prophases,3 metaphases,2 anaphases, 1 telephase. As shown in calculations, abundance are correspond as follows: Interphase=80. 32; Prophase=16. 279% ;Metophase=1. 744% ; Anaphase=1. 162% Telephase=0. 581% ; As we see interphase is equal to roughly 80%,however in book there was claim that interphase spend 90% of cell cycle. From this point could be proposed that root grown in favorable condition as it is known that in interphase cell is phase of rash activity, cell copy own DNA and energy is create for further mitosis. As shown in mitotic index formula, numerator contain only cells with visible chromosomes, that is mean that interphase is not taken to consideration.Mitotic i ndex enable to find a tendency to grow of cells. It is mean that how cell is divide, at which rate it is reproduces. In this experiment mitotic index is equal to 0. 197 Due to fact that there was not mitotic index scale it is difficult to say anything about tendency. In oncology(study of tuour cells) mitotic index has its special calibration, special standards. Error analysis Probability of error may cause the fact that in some case there was nuclear membrane without changing, but nucleoli had already vanished.So, there was probability of error to take to consideration the stage as a interphase and as prophase. Conclusion It is proved that is visible the dividing (in cell cycle) cells with method using a orcein ethanoic stain. Most of time cells a spend for interphase. This is proved by experiment result-80% of cells was at interphase stage. Most of all it is possible or easy to define exactly the stages such as anaphase, metaphase cause it definite characters are allow to do so. Th e late prophase and beginning of telephase is difficult to differentiate cause processes happened in them are opposite to each other.

Louisiana River Geography - 1904 Words

Louisiana’s Gulf Coast is eroding into the sea, and by 2100 most of Southeast Louisiana could be completely underwater. Not only does this threaten human and animal habitats, but also the energy, shipping, fishing, and tourist industries that have made this region of the U.S. a valuable part of the national economy (Marshall, 2014). In the past 200 years, half of the nation’s wetland habitats have been lost due to natural and manmade processes. Louisiana’s wetlands make up 40 percent of the total wetlands in the continental United States. 80 percent of losses, nationally, are of Louisiana’s coast (Williams).

This village’s small population and its 220 residential and commercial buildings are surrounded by marshes. In Cocodrie, there is no barrier against hurricanes. Local marinas play host to recreational and commercial fishing, and The Louisiana Universities Marine Consortium is located in Cocodrie. This facility of around 100,000 square ft houses laboratories, classrooms, and a research center. Infrastructure that will be affected by coastal erosion includes paved highway, dirt roads, a bridge, water supply systems, and natural gas lines. By 2050, Cocodrie will be surrounded by open water as the marshlands around the village give way to rising sea levels. Another community affected by this issue is Yscloske y, LA in St. Bernard Parish. The most important part of the economy here is fishing, and highways link the parish to New Orleans fishing communities. The Yscloskey area lies outside of the protective levees and is quite vulnerable to storms. Though losses in Yscloskey are not predicted to be as great as those in Cocodrie, a 16 percent loss by 2050 leaves the infrastructure of Yscloskey even more vulnerable (Coast 2050, 1998, p. 64-66).

The Theory By Charles Darwin Theory - 1371 Words

Theories of Motivation The theory by Charles Darwin theory, is where instinct theory is one of the motivational theories that has been applied in various organizations to shape organizational culture and structure. The theory has been applied along Maslow’s theory to enhance an adaptive culture in an organization. This paper evaluates the two theories and gives a deeper explanation on each. The research paper will also focus on providing a precise description and unresolved issues. The difference between the two theories, historical context of the two theories, a brief evaluation on if the theories address the biological, cognitive, and learned components, and to explore their application in a real life situation Maslow took a deeper approach of what motivates people from their personal view point. The scholar came up with the belief that there is always a set of motivation systems that are unrelated to rewards or desires that are unconscious, which triggered the development of Maslow’s need hierarchy theory. This theory is based on human needs, thoughts and the desire to be accepted and fit in society. In this theory, Maslow organizes needs in hierarchical from lower to higher order. The philosopher believed that once a lower need has been satisfied it ceases to motivate the preceding need, therefore changing how a person reacts and functions daily. (Maslow, 1974).

Macbeth 2 Essay Summary Example For Students

Macbeth 2 Essay Summary Responsibility for the TragedyIn Shakespeares classic tragedy of Macbeth the main character Macbeth is driven from his status as a well respected warrior and lord of not one, but two Scottish regions to a dishonest, unloyal murderer. Macbeth gets caught in a web of lies and vile acts of murder in which he brings about his own demise. His criminal actions lead up to his tragic ending of life. They have tied me to a stake; I cannot fly, But bearlike I must fight the course. His great ambition and gullibility of the witches predictions are two of the biggest factors of his downfall;however, Lady Macbeth was probably the biggest influence in the whole tragedy. Early in the tragedy, Macbeth is portrayed as a great leader and hero of many. He was a wonderful soldier who not only for for his country but for his King. During the course of the play though, Macbeth was greatly influenced by the supernatural forces of the witches. All hail, Macbeth that shalt be king hereafter! These witches led him to believe that he could be a King over all of Scotland if he would just do a few dishonest things to get what he wanted. If chance will have me King, why, chance may crown me, without my stir. Macbeth was gullible enough to believe the witches and thus led to his very own deception and demise. He brought himself to an even greater status than he began with but only through a gigantic web of lies which could not be untangled. He then felt lost and alone with nobody left to turn to. Lifes but a walking shadow, a poor player that struts and frets his hour upon the stage and then is heard no more.However Macbeth was not the only influence in this great tragedy. Lady Macbeth played a large role as Macbeths seductress and brainwasher. Lady Macbeth persuaded her husband to kill the King not so that he would himself be King but so that she could be Queen.Although because of her involvement in this web of lies she felt guilty and drove herself insane worrying about what had happened and what would happen to her and her husband for being so dishonest. She was not responsible for the tragedy, she was only a manipulative factor in the scheme of things. Even though it does take two to tango, Macbeth tangoed on his own. After the death of Duncan Macbeth begins to work on his own without the help of his wife. He plans the murders of Banquo and the heir to the throne, Banquos son Fleance. Although it does not turn out as expected Macbeth remains calm until Banquos ghost appears. and keep the natural ruby of your cheeks, when mine is blanched with fear. This was the turning point in the whole story because until this point everything was going great for Macbeth, he had power, fame and fortune, all you could ever want;however, when this ghost appeared Macbeth went on a little insanity trip. He, also like his wife was engulfed with guilt and unable to function properly anymore. This led to another visit with the witches. Showing his overconfidence, Macbeth believed the three apparitions shown to him by the witches and was then extremely calm. He felt that no man could ever harm him thus he had nothing to worry about.

His ambition is crushed and he is portrayed as a dead butcher because he killed so many people to get where he was but he never achieved exactly the status that he had hoped for. Macbeth killed Macbeth. He brought everything upon himself and deserved everything he received. He could blame it on his wife or on the witches but that just would not be justifiable because he did not have to listen to any of them. He killed everyone who in the beginning were his lov ed ones and did not show any guilt or remorse for doing it. Is that a hero? No. A hero is a man of exceptional quality who wins admiration by his noble deeds. Once again, Macbeth killed Macbeth. He tangoed alone this time.

Small Big Man Essay, Research Paper Populating Two Lifes My bosom soars like a hawk. Small Large Man was a adult male of many traits, of many backgrounds. At a immature age his life as he knew it came a drastic arrest when he and his household we attacked by Indians. He was drug from the tattered waggon by a human being and put on his Equus caballus. The Indian had taken Jack back to the others, and non long after, he fell into the folk like he was one of the human existences. His Aunt had escaped during the dark, taking doodly-squat to believe that she would return for aid. Old ages passed and Jack grew with the human existences, going one of them to most utmost. He even painted his tegument a darker colour to fit the remainder of the folk. Jack had grown strong for rolling into the folk, and accommodating their ways, nevertheless, he was ever little for his size, and was invariably teased. We will write a custom essay sample on Little Big Man Essay Research Paper Living or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page His Grandfather had one time told him the narrative of Big Man, and certainly adequate Jack became known as Little Big Man. He incorporated many of the instructions of a white adult male into his manner of life as a human being. He would acquire into fisticuffss with other tribe members, and they would be stunned because they had neer seen this type of contending earlier. He learned to be portion of the folk, though subject, and finding he rose up to be respected member of the group. Although hated by some of his equals, I think it might hold been because some felt that he was portion of the white adult male s cause. After salvaging one member s life this did non even alteration, he knew he must refund Little Big Man, but neer accepted him as one of them. Time flowed like the Waterss of the river, and Little Big Man grew older. The white adult male had come to assail, and the Indians were traveling to learn them a lesson. Small Large Man had joined them, but as they were out, a frie nd of his was shot and Little Big Man tried to assist him. As this went on another white adult male attacked Small Big Man, and knocked him to the land. He was captured and about killed, until he blurted out that he was a white adult male excessively. These were the words that saved his life several times. Now populating with a White household as their boy Jack was back to the white ways of curse, cheating, and discourtesy. I m so proud. The adult female that Jack was remaining with was a really spiritual, and told Jack to disregard the impulses he feels. At a sodium carbonate store that they had gone to, Jack was imbibing from the fountain, while she had left. He went down to the cellar to happen the adult male and her holding sexual dealingss. I think that at that minute Jack realized the truth about the white people, he realized at that clip that the Whites are non all that they appear to be. We live in camouflage, concealing from the truth, in fright of what others will believe. The lowest of the low. When I think of Jack I think of a chameleon, being able to accommodate with the ever-changing environm ent. Once he was a white adult male, so a human being, so back t a white adult male. He made usage of his yesteryear and claimed portion of both groups. Some would name him a coward, but I think he did the smartest thing he could hold. He like many people did non cognize where he belonged. He tried to be portion of the Indians and tried to suit in as a white adult male, but he found himself resiling back and forth merely doing him giddy and baffled. I think there were a twosome of times that he truly knew where he belonged, like when he saw his friends daughter giving birth ( Sunshine ) , or when he saw her and his kid being killed by the white adult male. All of which contributed to his concluding determination to remain with the human existences. A twosome of instances in the film portrayed the white adult male as the barbarian, alternatively of the Native American. As a discovery point in movie devising, Little Big Man took a varying point of view when compared to the old Westerns that can before it. These Westerns would frequently propose that Indians were nil more than waggon attacking, barbarians. Small Large Man takes another measure toward clear uping the fact that it was non the Indians, but instead the Whites that were the barbarians. The Human Beings were peaceable, and respectful of one another, but as the film progresses you see that the Whites are frequently caught rip offing, lying, and scamming their manner to acquire by. This does non even touch on the affluent category, which I m certain, would be worse. The most memorable characters to me, were that of the homosexual Indian, and General Custer. Although they do non look like the largest functions, they do play a critical portion in the film. The homosexual Indian is really of import, in that he symbolizes many things. One thing that he seems to demo is how non even the Indians are perfect. They realize that there are things in life that you cant explicate, but unlike others they except this difference, and see him another homo being. Besides it shows that these are people excessively, and it breaks the stereotype of the male Indian as the strong huntsman type. General Custer is a strong character, because he sums up all that is incorrect with the Whites in himself. He is the psyche of the Satan himself, or so the film advocates. At the terminal of the film during the Battle of Little Horn, it seemed like Custer had lost it wholly, and had flipped. I do non cognize if this is genuinely historically accurate, but he was portrayed as a nut and it truly made him look bad. In the film, they neer did reference anything about them traveling in to reconnoiter for a good location of a garrison ; they merely attacked the Indians. The movie, although entertaining, was missing some of import facts, and I think that is what sort of led the spectator to being bias. If all the facts were included along with the wit, we would hold had a good film, nevertheless, a really long one at that. But so once more look at Dances With Wolfs.
