I will pay for the following article Potasium. The work is to be 2 pages with three to five sources, with in-text citations and a reference page.

POTASSIUM Potassium Potassium element plays a pivotal role in the body and plant systems. According to Roza, (2007), Humphrey Davy discovered the element 1807. He managed to isolate this element through electrolysis method making it the pioneer the use of this approach in isolation of other elements (Shaposhnik, 2007). To date, the element is acquired through electrolysis of hydroxide or chloride because it is not found freely in nature (Roza, 2007). It was until the eighteenth century that Potassium and sodium were distinguished.

Potassium is an essential dietary mineral. Regulation of potassium levels inside and outside of cells affect normal bodily functions. Potassium is a chemical element represented by the symbol K and atomic number 19. Elemental potassium is a silvery-white metal, oxidizes quickly in the air, and reacts with water (Shaposhnik, 2007). During reaction with water, hydrogen is emitted and the heat generated is sufficient to ignite the hydrogen and burns with a lilac flame (Woodford, 2002). Potassium and Lithium are the least dense known metals.

Interestingly the composition of the element makes up about 1.5% the earth crust’s weight. It is one of the most common mineral elements though it is rarely found naturally. It is found in crystalline form as feldspars or micas (Woodford, 2002).Roza (2007) ascribed that people used plant ash to make soap. Later on scientists discovered that plant ash is composed of potassium (Roza, 2007). The main applications of potash were the production of glass, soap, bleach, and gunpowder as potassium nitrate.

The discovery of potassium chloride mineral deposits in Germany led to the mass production of potassium-containing fertilizers.The humans require this element for proper functioning of the system. There are events that leads to abnormal functioning that relates to deficiency of the element for instance consumption of coffee, alcohol, severe stressing of the body, excess strenuous physical and using potassium-wasting diuretics deprives the system of this element leading to hypokalemia (Roza, 2007. Woodford, 2002).

Potassium deficiency leads to muscle weakness, severe fatigue, cardiac arrest, nervous disorders and poor reflexes can occur. Other conditions that influence the risk of hypokalemia include severe vomiting or diarrhea, abuse of laxatives, anorexia or bulimia, Magnesium deficiency and congestive heart failure. Excess potassium in the body could lead to dehydration. The kidneys regulate the concentration of potassium in the body (Roza, 2007. Woodford, 2002). Potassium is the most absorbed mineral element by plants than other mineral elements and is essential for growth and metabolic processes (Woodford, 2002).

Potassium and sodium work together for several purposes. The combination aids in the regulation of body waste, control heart rhythms, and blood pressure (Roza, 2007. Woodford, 2002). It also sends oxygen to the brain thus clear thinking. Being an electrolyte, it regulates the balance of fluids in cells, including blood.It helps the plants in the growth of vegetation. It regulates and maintains the body system. Therefore, having adequate quantities of potassium helps the system performs its functions accordingly.

It must be regulated, excessive or deficiency could be hazardous to health.In conclusion, potassium is a vital element for both animal and plants because it plays essential regulatory function. Deficiency of this element can lead to problems that would be costly to manage. Its discovery was a breakthrough not only for the medical and industrial application but also for subsequent studies that aims to improve living condition.Table showing the properties of potassium elementPhysical properties of the elementColourMetal with silvery and white colour (Roza, 2007.

Write a 2 pages paper on cognitive development: information processing. How important is “rote/drill” in teaching? How important is discovery -based teaching/learning important over direct teaching?

Rote/drill in teaching is simply defined as making the students to memorize the information by mere repetition. Most of the teachers in the today’s world employ this technique without even realizing the fact that they indeed are employing this technique. The biggest examples of rote learning are the alphabets, mathematical tables and statistical formulas. Rote/drill way of teaching indeed plays an important role in the today’s learning climate. It is the most easiest and efficient way to instill knowledge in students. It forms a solid foundation and base within students on which one can build intellectual superstructures. There is no way to learn arithmetic facts other than rote learning. It is also important in learning to read, for example helps read an alphabetic writing system to produce a phonetic reflex. Most of the time, rote/drill learning is used by teachers to make students learn difficult poems, drama scripts, music lyrics and symbols. Thus, it may be considered as an ancient technique, it is still prevalent in the today’s education system (Blumenfeld 34).

Discovery learning. an instructional and student driven model, provides an active and hands-on learning opportunity for students as compared to direct learning. teacher based, doesn’t involves students to a larger extent and is already formulated according to the teacher’s will. On the other hand, in discover learning, the students take on an active role to create, generate and integrate knowledge. This type of learning further aids students to learn at their own pace. Thirdly, students are made to learn new knowledge by affiliating scenarios with their past experiences ( Castronova 2).

2. What are the common learning disabilities that you find in your classrooms? Do you think culture has a role in terms of identifying and labeling disabilities?

Every now and then, we hear about students suffering from learning problems/disabilities in their respective classrooms. Some of the common learning disabilities are as follows. Dyslexia is defined as difficulty in reading, dyscalculia relates to difficulty with doing math’s, dysgraphia is recognized as students facing difficulty with writing, dyspraxia relates to difficulty with fine motor skills of students, aphasia is known as difficulty with language, auditory processing disorder is defined as problems in hearing differences between sounds and visual processing disorder relates to difficulty in interpreting visual information. All these are some of the renowned learning disabilities students’ face in their classrooms (Kemp, Smith and Segal 4).

Culture indeed has an effective role in terms of identifying and labeling disabilities. It greatly depends upon the society’s culture how they view different kinds of disabilities. They are various stereotype societies whose culture consider LD students as stupid and retard which actually is not the case. The society’s culture should inculcate “cure and relief” for all the people having disabilities rather than treating them as mentally retarded students. Culture can make or break students having learning disabilities so it should play a positive role instead of de-motivating such students (Bakken, Obiakor and Rotatori 50).

Compose a 500 words assignment on the advantages and disadvantages of social media. Needs to be plagiarism free! Technological advancement has not only improved development through industrialization but also social life. The invention of social media remains one idea that has been applauded for various reasons. Evidently, social media offer a platform for various advantages. To start with, it opens communication, hence promoting information delivery and discovery. Indeed, the 21st century has people with the highest access to information as compared to other generations. They read news through Facebook, updates on Twitter and other social sources. Apart from communication, social media has also improved the working environment. It allows employees and employers alike to post ideas, ask questions and share good links that either improve relationships or the working environment. Notably, this has helped in facilitating business growth. Additionally, social media open the playing field for business contacts. Certainly, this is because of the wide audience ranging from adults to youths. Additionally, it has served as a recruitment tool that expands market research instruments, direct clients to specific websites, and most propel marketing campaigns. In the professional fraternity, social networking initiates a like-minded platform where academicians and scholars share ideas and important research. According to Bozarth, “a blog can even be used to host an entirely online course.” (Bozarth 84) From this perspective, the process has expanded the horizon of knowledge leading to more discoveries and exposure.

Among the many disadvantages, one cannot fail to capture the social ills associated with the discovery. Notably, hackers have been on the rise mainly in social media. They commit fraud, initiate virus attacks and launch spam problems that expose personal information. People have also fallen prey to online frauds leading to identity theft and other online swindles. Identifying genuine users of social media is currently the main challenge in the social media fraternity. Conceivably, this is because of people targeting unsuspecting users hence reducing ethical levels of the modern trend. Interestingly, social media is not only a communications site but also a legal playing field. The legal consequences of postings between employees and employers in social media in many instances have resulted in lawsuits. In as much as social media has introduced discussion forums in the education sector, it has done more harm. Students are no longer interested in research but concentrate on social media (Bozarth 91). Moreover, it can affect productivity when employees are keen on updating profiles instead of concentrating on the assigned roles.

In conclusion, social media remain one of the great interventions with both advantages and disadvantages. It has improved access to information, promoted a serene work environment, and most importantly helped research. On the other hand, it opened floodgates for social ills ranging from scams, pornography, online prostitution, and identity theft. Additionally, it has shifted the attention of students and employees from their focus leading to poor productivity. In essence, social media is both a blessing but a curse in disguise.

The BDI, on its development and the application, was meant to pinpoint, detect, access, analyze, and monitor alterations min depressive symptoms amongst persons in a mental health care dispensation. Health care practitioners use it to additionally detect depression symptoms in a primary care institution. Moreover, the BDI assessment tool normally takes from five to ten minutes to complete in the course of medical or psychological examinations and analyses (Groth-Marnat, 2011). With regard to precautions on its application, it is notable that the BDI is only for application by learned and trained professionals.

However, it is pertinent to let administrative and knowledgeable health practitioners. who are thoroughly qualified in its application and interpretation, people can administer it on self.Beck innovated and developed the BDI assessment tool in 196 1. Furthermore in the course of its development, health practitioners in this field formally adapted it in the year 1969, and they copyrighted it in 1979. A second version of the inventory referred to as BDI-II was innovated to reflect and embody revisions of the fourth edition revision of the text of the Diagnostic and statistical manual of mental disorders.

This is a resourceful handbook that mental health practitioners apply in diagnosing mental disorders (Ward, 2002).Furthermore, the long form of the BDI assessment tool comprises twenty-one queries or items, each inculcating four probable responses. Besides, each response or answer is assigned a distinct score value that spans from zero to three. Additionally, it indicates the severity or seriousness of the tested symptom. A version is meant for application by the primary care practitioners, BDI-PC, inculcates seven self-administered items or queries (Ward, 2002).

Each of the questions correlates to a symptom that is part of radical depressive disorders. It analyses in terms of personal experiences over the past two weeks.In the BDI test, the individual assessments and evaluations include issues surrounding mood, sense of failure, punishment, work adversities, self-esteem, physical preoccupation, fatigue, a decrease of libido, and punishment. Moreover, it assesses aspects such as social withdrawal, suicidal thoughts, dissatisfaction, and personal accusation, feelings of guilt, and irritability of a person.
