Discuss the Process of Osmo-Regulation in Paramecium - 550 Words

Discuss the Process of Osmo-Regulation in Paramecium (Coursework Sample) Content: Studentà ¢Ã¢â€š ¬s NameProfessorà ¢Ã¢â€š ¬s NameCourseDateParamecium and OsmoregulationParamecium is a unicellular organism belonging to genus, Protozoa. Like many other Protozoa, paramecium has ciliated body that aids in locomotion. The habitants of protozoa vary from fresh water bodies, marine water, brackish and stagnant waters in in basins and ponds, (Ladenburger 7). Some species of paramecium can easily be cultivated and induced to conjugate. Due to these characteristics, paramecium has been used in laboratories for research purposes. The body of a paramecium is covered by cytoplasmic structures which are called cilia. Cilia are hair like structures which helps the organism in movement. The flickering movement of cilia propels the organism hence enables it to move. Paramecium has got cellulose cell-wall which enables it to have distinct shape. Unlike amoeba, paramecium has distinct permanent shape. Each and every cell organelle in paramecium cell has a distinct purpose; they occupy specific area of the cytoplasm, (Ladenburger 13).Osmoregulation is a process by which an organism maintains a homeostatic balance between the body fluid and the surrounding environment or cells. Single-cellular organisms have to maintain homeostatic balance between the cytoplasm and the surrounding habitat. Paramecia are adapted in a way to help them maintain the concentration of the body fluid so that it does not become too dilute or too concentrated. To maintain osmoregulation, paramecium has a contractile vacuole where water absorbed as a result of the osmotic gradient, accumulate, and move towards the cell wall and release the water through the pores (Wassmer 18). The organism ingests the food through cytostome. Paramecium reproduces through binary fusion. This is an asexual reproduction where the mature organism divides to form new organisms. After feeding on single celled algae and fungi, paramecium absorbs the food for energy and cell division. The waste material is produced in form of urea, calcium, potassium, sodium, etc. The figure 1 below shows a diagram of a paramecium.Figure 1: A diagram of Paramecium: D G Mackean. Biology Teaching Resources. Educational Articles, 2016: -resources.com/paramecium-01.htmlThe waste materials from paramecium, after digestion, then accumulated in the cytoplasm. Because plasmodium lives in fresh water, there will be high concentration of solute in the body of the plasmodium than the outer environment. This great concentration gradient between the body of the plasmodium and the surrounding causes osmotic potential to the plasmodium cell, (Wassmer 25). Due to osmosis, we expect that water will be drawn from the surrounding into the plasmodium cell making it burst. However, plasmodium is well adapted to the condition which enables it to survive such great osmotic difference.The contractile vacuoles of ciliates are permanent structures that theoretically squeeze out excess water through a tiny pore. I n some paramecium the contractile vacuole have conspicuous feeder arms. But in most ciliates, the canal system is less apparent and the contractile vacuole appears as a simple sphere, (Ladenburger 21). After some time, the concentration of the waste materials reaches a level that has ...

Review Of Related Literature On Classroom Management

Chapter 2 Review of Related Literature Introduction to Classroom Management In the field of teaching, teachers are known to have multiple titles such as a lesson planner, teacher, and a classroom manager. It is important that teachers have a year where the students are learning rather than the teacher having to discipline the class over again about the classroom and school rules. Therefore, teachers need to establish an appropriate classroom management tool for the classroom where students are ready to learn each day. What is classroom management anyways? Classroom management can mean a lot of things too many different people depending on how it is seen in school. In elementary schools for instance, schools typically use a common†¦show more content†¦When it came time for punishing students for misbehaving they turned away from using corporal punishment and used their own approach to punish students (Kaliska, 2002). Those who failed to follow the rules either had a wooden log placed around their neck as a pillory, put in sacks, baskets, or even hung from the school roof (Reigart, 2012). Parents and others were still not happy with the way students were being disciplined in schools so again classroom management changed in schools. In the end of the 19th century students were separated by their age rather than by how smart they were in school. This became known as the bureaucratic discipline were teacher introduced different teaching techniques with bureaucratic discipline. Students that we re misbehaving in class were still being punished by a wooden paddle and other devices (Summerville, 2014). This is similar to the type of classroom that we see today in schools, but teachers and administrators took away punishing students with wooden paddles to focus on learning. Schools and teachers began to look at the school environment and saw that the environment the students were coming to became unsafe for them to learn. In the 20th century, intrinsic and extrinsic motivation became the new focus in the education world. Teachers began to learn how to motive students to learn through positive rewards. One motivator is called intrinsic motivation which engages the student in the behavior that is personallyShow MoreRelatedAmerican Educational System1220 Words   |  5 PagesArticle Critique EDT 660 Fall, 2005 Your Name: Monroe, C.R., Obidah, J.E.

Know All about UCC In Contract Law

Question: Describe about the UCC in Contract Law. Answer: What is the UCC and when does it apply? UCC can be defined as the uniform commercial code, which is a large body of regulations governing and administering the business transactions. Usually Uniform commercial code deals in those transactions, which are related, to personal property but not to real property. The code was initially published in the year 1952 (Speidel Schott, 2013). Universal Commercial Code is applicable to supplemental bodies of law. Universal commercial code was drafted as the background of the prevailing bodies of law, which generally consists of common law and equity. However, UCC cannot be used to complement the provisions of Universal commercial code. If there is no statutory provisions provided under law it allows the common law and equity principles to act as supplement to UCC. What warranties are provided by the UCC? Warranties provided by UCC are as follows Express Warranties: Express warranties are affirmative statements by a seller to a purchaser in relation to the goods sold. Express warranties are usually taken in the form of advertisements or certificates (Speidel Schott, 2013). However, it must also be noted that express warranties can also be in the form of oral and written format. Implied warranties: These are those warranties, which automatically exist in the goods when it is sold to a buyer without the need of any specified affirmations. However, implied warranties consists of two forms which are as follows Implied warranty of merchantability: Article two of the Implied Warranty of merchantability states the general standards where goods are merchantable. Disclaiming Implied Warranties: Under the disclaiming implied warranties sellers can exclude or modify the implied warranties. However, in order to do so the sellers usually provide the exclusion record in a printable form of document. Uniform Fraudulent Conveyances Act and Fair Debt Collection Practices Act are the laws that offer legal aid to debtors and creditors. As such, they ensure fair trading practices in the domestic market and international market. These laws play a pivotal role in the maintenance of fairness and transparency during the trading of goods and services. Reference list: Ayres, I. (2012).Studies in Contract Law. Foundation Press.
