Atticus Finch Biography

Atticus Finch Biography Atticus Finch is one of the greatest fictional figures in American literature. Both in the book and in the film, Atticus stands larger-than-life, bold-and-courageous against the falsehood and injustice. He risks his life and his career (seemingly without care), as he defends a black man against charges of rape (which were based on lies, fear, and ignorance). Where Atticus Appears (and Inspiration for This Character): Atticus first appears in Harper Lees only novel, ​​To Kill a Mockingbird. He is said to have been based on Lees own father,  Amasa Lee, (which puts a possible autobiographical slant to this famous novel). Amasa held a number of positions (including a bookkeeper and financial manager)he also practiced law in Monroe County, and his writing explored race-relations topics. When he prepared for the role of Atticus Finch in the film version,  Ã¢â‚¬â€¹Gregory Peck went to Alabama and met Lees father. (He appears to have died in 1962, the same year the Academy-Award-winning film was released). His Relationships During the course of the novel, we discover that his wife died, though we never find out how she died. Her death has left a gaping hole in the family, which has been (at least partially) filled by their housekeeper/cook (Calpurnia, a stern disciplinarian). There is no mention of Atticus in relation to other women in the novel, which seems to suggest that he is focused on doing his job (making a difference, and pursuing justice), while he raises his children, Jem (Jeremy Atticus Finch) and Scout (Jean Louise Finch). His Career   Atticus is a Maycomb lawyer, and he appears to be descended from an old local family. Hes well-known in the community, and he appears to be well respected and liked. However, his decision to defend Tom Robinson against the false charges of rape lands him in a great deal of trouble. The Scottsboro Case, a legal court case involving nine black accused and convicted under extremely dubious evidence, occurred in 1931when Harper Lee was five-years-old. This case is also an inspiration for the novel.

Cell Biology

Cell Biology Cell Biology What Is Cell Biology? Cell biology is the subdiscipline of biology that studies the basic unit of life, the cell. It deals with all aspects of the cell including cell anatomy, cell division (mitosis and meiosis), and cell processes including  cell respiration, and cell death. Cell biology does not stand alone as a discipline but is closely related to other areas of biology such as genetics, molecular biology, and biochemistry. Key Takeaways As its name implies, cell biology deals with the study of the cell, the basic unit of life.There are two cell types: prokaryotic and eukaryotic cells. Prokaryotes do not have a defined nucleus while eukaryotes do.The invention of the microscope was pivotal in scientists ability to properly study cells.A number of career paths, like a clinical researcher, a medical doctor or a pharmacologist are open to those who have studied cell biology.Many important developments have taken place in cell biology. From Hookes description of a cork cell in 1655 to induced pluripotent stem cells advances, cell biology continues to fascinate scientists. Based on one of the basic principles of biology, the cell theory, the study of cells would not have been possible without the invention of the microscope. With the advanced microscopes of today, such as the Scanning Electron Microscope and Transmission Electron Microscope, cell biologists are able to obtain detailed images of the smallest of cell structures and organelles. What Are Cells? All organisms contain cells. Viaframe/Corbis/Getty Images Plus All living organisms are composed of cells. Some organisms are comprised of cells that number in the trillions. There are two primary types of cells: eukaryotic and prokaryotic cells. Eukaryotic cells have a defined nucleus, while the prokaryotic nucleus is not defined or contained within a membrane. While all organisms are composed of cells, these cells differ among organisms.  Some of these differing characteristics include cell structure, size, shape, and organelle content. For example, animal cells, bacterial cells, and plant cells have similarities, but they are also noticeably different. Cells have different methods of reproduction. Some of these methods include: binary fission, mitosis, and meiosis. Cells house an organisms genetic material (DNA), which provides instructions for all cellular activity. Why Do Cells Move? Cell movement is necessary for a number of cell functions to occur. Some of these functions include cell division, cell shape determination, fighting off infectious agents and tissue repair. Internal cell movement is needed to transport substances into and out of a cell, as well as to move organelles during cell division. Careers in Cell Biology Study in the field of cell biology can lead to various career paths. Many cell biologists are research scientists who work in industrial or academic laboratories. Other opportunities include: Cell Culture SpecialistClinical Quality AuditorClinical ResearcherFood Drug InspectorIndustrial HygienistMedical DoctorMedical IllustratorMedical WriterPathologistPharmacologistPhysiologistProfessorQuality Control SpecialistTechnical WriterVeterinarian Significant Events in Cell Biology There have been several significant events throughout history that have led to the development of the field of cell biology as it exists today. Below are a few of these major events: 1655 - Robert Hooke gives first description of a cork tree cell.1674 - Leeuwenhoek views protozoa.1683 - Leeuwenhoek views bacteria.1831 - Robert Brown was first to identify the nucleus as an important cell component.1838 - Schleiden and Schwann introduce what would become the Cell Theory.1857 - Kolliker describes mitochondria.1869 - Miescher isolates DNA for the first time.1882 - Kock identifies bacteria.1898 - Golgi discovers the Golgi apparatus.1931 - Ruska builds the first Transmission Electron Microscope.1953 - Watson and Crick propose structure of DNA double-helix.1965 - First commercial Scanning Electron Microscope produced.1997 - First sheep cloned.1998 - Mice cloned.2003 - Human genome DNA sequence draft completed.2006 - Adult mouse skin cells reprogrammed into induced pluripotent stem cells (iPS).2010 - Neurons, cardiac muscle, and blood cells created directly from reprogrammed adult cells. Types of Cells The human body has a multitude of different types of cells. These cells differ in structure and function and are suited for the roles they fulfill in the body. Examples of cells in the body include: stem cells, sex cells, blood cells, fat cells and cancer cells.

Apply the Three-Step Writing Process to business communication Essay

Apply the Three-Step Writing Process to business communication. Establish brief and effective business communication routines - Essay Example Persuasive messages have also been used in this trade. They have been used to get different parties interested in the projects and dealings they are in. This paper will review the importance of persuasive messages in attaining the desired results. When projects are about to be started in any organization, it is the manager’s job to persuade others to follow. Without effective communication as to how the project will help them, it is almost impossible to have the task done (Stiff & Mongeau, 2003). This is where the manager or person in charge will employ the three step writing process. It will be used to write a persuasive message to the subordinates or other parties pertinent to the project. With the employment of this method of writing, the person in charge should be knowledgeable on how to reach the audience (Perloff, 2010). Trying to convince the managers at whole foods market about the new program will require a persuasive e-mail. This may be used to have them excited about helping with the expanding of the project. The following is an e-mail that will be addressed to the managers at the Whole Foods Markets trying to get them interested in the program developed to help the market reach to more people and also, be appreciated more. Hello, hope your days are filled with good tidings. The reason for writing this message is to find the best solution to the program we developed earlier. The program was about the donation of food to many more parts than the occasional parts usually reached. As seen earlier, the program has been much appreciated by all the people who have sampled some of your products. It will be of great importance if a far broader outreach was created to get to them on a more occasional basis. The project may help benefit this program more with all the places we may get to take your products. Some of your ideas are welcome to ensure that we come up with the best possible way to go about this project. We appeal to
