Zoology. Mitosis and biglight phases of embryological development Essay

Zoology. Mitosis and biglight phases of embryological development - Essay Example Mitosis is divided into these following phases: prophase, prometaphase, metaphase, anaphase and telophase. Prophase is when the chromatin liquefies into a structure known as a chromosome, which allows the chromatin to become visible. Prometaphase is what happens when the nuclear envelope breaks itself into smaller fragments and then disappears entirely. Metaphase takes place when the chromosomes are situated in the center of the cell prior to splitting into the two daughter cell sets. Anaphase is when the chromosomes separate within the eukaryotic cell. The last phase, telophase, is when the stages and effects of prophase and prometaphase are reversed within the eukaryotic cell. Meiosis takes place when the chromosomes are split into halves, and is an essential part of sexual reproduction. Meiosis has many more complex stages then mitosis, as seen in the following: meiosis 1, prophase 1 (which consists of these further stages: leptotene, zygotene, pachytene, diplotene, diakinesis, and synchronous processes), metaphase 1, anaphase 1, telophase 1, and meiosis II. In meiosis 1, the homologous chromosomes are separated into two haploid cells. During prophase 1, the pairs of homologous chromosomes recombine with other pairs. The following are the phases of prophase 1: leptotene - each separate chromosome condenses into long threads inside of the nucleus; zygotene - the thread-like chromosomes line up with each other;

Analysis on an Operation - Research Paper Example The activities of the operation management mainly range from the strategic, tactical to operational levels. Tactical issues involve the layout of the plant and structure, the selection of equipment and replacement, and the methods of the project management. On the other hand, the operational issues involves the handling of traffic and materials, the equipment maintenance, the quality inspection and control, the inventory management and production scheduling and control. Operation management therefore focuses on the effectiveness and efficiency of the processes. The nature in which it is carried out in an organization depends on the nature of the products or services in the company such as wholesale, retail or manufacture. Shipper manufacturing company has various operational processes that enable efficient production of its products. The operation process entails the type of product or product design, the product process flow, management of quality, supply chain management, project m anagement or operation scheduling, forecasting and the inventory management. Good management of the operation processes contributes to the well performance of the company. It also helps the company to maintain its production supply and increases The Company’s development as a whole. ... The divisions include the material division (MD), Electrical Products Division (EPD), and the Advanced Product Division (APD). These divisions are located in Faribault. Minnesota. The company holds a good position in sales because of the high efficiency levels. In addition, the company has improved growth and is in a good position on productivity. Analysis of the product and product design Shipper manufacturing company manufactures various products. Some of the products manufactured include electrical products, laminated materials and specialty products. Advanced product division (APD), is a division in the company that manufactures the specialty products. Initially, APD manufactured custom products in very low volumes for the consumers. The consumers got very little products that could not satisfy their desires. However, the division plans to increase the volume of production for the multiple customers. Â  The company therefore would require increasing its operational management in order to maintain its competition in the new environment. APD produces specialty products mainly for the custom orders such as helicopter blade liners, and mine stoppers. In addition, shipper manufacturing company produces many aerostats per year which are sold to different communication companies. Furthermore, they are also sold to some foreign countries and the U.S. government mainly for communication purposes. The operation process flow analysis The production flow involves the movement of various items through the production process. Â  The flow structure or the process flow used in production purposes has various impacts on the operation layout, technological decisions, recourses and the methods used in doing the work. The process flow is a very important aspect in Shipper
