Alcedo, Mara Mae Q. Ledesma, Chandy Mae T. Marable, Krystel Marie P. Riego de Dios, Ancel B. Thian Nun Mawi, Sarah Chapter I The Problem and its Background Introduction Language is one of the liberal arts on which education in every school offers is based. The school wants to help the students to improve their abilities to communicate their thoughts and feelings effectively in English, for it is the second official language of the country. There are two types of communication, the verbal communication and the non- verbal communication. Being a Filipino it is the “lingua franca” of social, professional and the business world as to develop one’s proficiency in English. However, what are the factors that affect poor communication skill among students especially on PCU. In addition, what is the importance of communication in their future field of work? As English Major Students, one studies literature, language, culture, history and develop skills and knowledge on the four aspects of communication arts namely: listening, speaking, reading and, writing. Communication is the most important tool humans have to interact with each other. Effective is required to learn, succeed in business and relate well with others in personal relationships...

...write a chemistry paper for the final assignment. When I started thinking about a topic the wheels started to turn. I than found myself asking the question, what is chemistry exactly? Chemistry is the scientific study of interactions of a chemical substance that are constituted of atoms or the subatomic particles that include protons, electrons, and neutrons. Atoms combine the produce molecules or crystals. Chemistry is often called "the central science" because it connects the other natural sciences such as astronomy, physics, material science, biology, and geology. The genesis of chemistry can be traced to certain practices, known as alchemy, which had been practiced for several millennia in various parts of the world. Then I wonder that a chemical reaction is. A chemical reaction is a transformation of some substances into one or more other substances. It can be symbolically depicted through a chemical equation. The number of atoms on the left and the right in the equation for a chemical transformation is most often equal. The nature of chemical reactions is that a substance may undergo the energy changes that may accompany it are constrained by certain basic rules, known as chemical laws. So what is a chemical law? Chemical laws are those laws of nature relevant to chemistry. The most fundamental concept in chemistry is the law of conservation of mass, which states that there is no detectable change in the quantity of matter during an ordinary chemical reaction. Modern physics...

...Regulatory Behavior Paper Debra Sebastiano PSY/340 May 18, 2015 Professor Mark Schmitz The nervous system is accountable for organizing the body's daily actions. It not only controls the upkeep of regular roles but also the body's capability to deal with emergency circumstances. When talking about the nervous system we are talking about three overall functions, the first function is the sensory function, the second is an interpretative function and the third is a motor function. The sensory nerves collect data from the inside and outside (environment) of the body and then transport that data to the central nervous system (CNS). The sensory information that was transported to the CNS is then processed and interpreted. The motor nerves transport information from the CNS to the muscles and the glands of the body (The Nervous System, 2008). The nervous system is separated into two parts - the first part is called the central nervous system (CNS), the central nervous system is made up of the brain and spinal cord. It is protected by bone and blocked from damage by the cerebrospinal fluid (CSF). The brain is an organ of soft gray matter tissue, which is compacted within the skull of vertebrates. There is also white matter which can be found deep inside the brain, at the border of the spinal cord and the peripheral nerves. The brain is divided into four parts the cerebrum, diencephalons, brain stem, and cerebellum: * Cerebrum – this is the biggest part of the brain,...

...2009 - 2:00 PDT The word malaria comes from 18th century Italian mala meaning "bad" and ariameaning "air". Most likely, the term was first used by Dr. Francisco Torti, Italy, when people thought the disease was caused by foul air in marshy areas. It was not until 1880 that scientists discovered that malaria was a parasitic disease which is transmitted by the anopheles mosquito. The mosquito infects the host with a one-cell parasite called plasmodium. Not long after they found out that Malaria is transmitted from human-to-human through the bite of the female mosquito, which needs blood for her eggs. According to Medilexicon's medical dictionary, Malaria is "A disease caused by the presence of the sporozoan Plasmodium in human or other vertebrate erythrocytes, usually transmitted to humans by the bite of an infected female mosquito of the genus Anopheles that previously sucked blood from a person with malaria…" (Click here to see the complete definition in the dictionary). Malaria is also known as Jungle fever, Marsh fever, Paludal fever Approximately 40% of the total global population is at risk of Malaria infection. During the 20th century the disease was effectively eliminated in the majority of non-tropical countries. Today Malaria causes over 350 million human acute illnesses, as well as at least one million deaths annually. The anopheles mosquito exists in most tropical and many sub-tropical countries of Latin America and the Caribbean, Africa, Oceania, and Asia. According...

...Dinosaur extinction is still a major mystery of earth history. In this review article, extinctions in the geological record will be briefly mentioned. Many of the imaginative theories for the extinction of the dinosaurs will also be presented. Within the uniformitarian paradigm, the meteorite impact theory, once considered ‘outrageous’, now is the dominant theory. However, the volcanic theory is still believed by a majority of paleontologists. Both theories have their strengths and weaknesses. The unscientific behavior of those involved in the meteorite paradigm change will be briefly explored. Evidence that the dinosaurs died in a cataclysm of global proportions will be presented, such as the huge water-laid dinosaur graveyards found over the earth. Occasional nonspecific bone-beds and the rarity of fossils of very young dinosaurs suggest a catastrophic death and burial. The billions of dinosaur tracks recently discovered provide testimony to unusual, stressful conditions. Nests, eggs, and babies are a challenge to a Flood model, but there are enough unknowns associated with the data that solid conclusions are difficult to draw. The part that impacts and volcanism play in a Flood paradigm will be briefly discussed. The question of whether the K/T boundary and the extinction of the dinosaurs should be considered a synchronous event within the Flood will be considered.

Niklas The modern theory of biological evolution: an expanded synthesis Published online: 17 March 2004 Springer-Verlag 2004 Abstract In 1858, two naturalists, Charles Darwin and Alfred Russel Wallace, independently proposed natural selection as the basic mechanism responsible for the origin of new phenotypic variants and, ultimately, new species. A large body of evidence for this hypothesis was published in Darwin’s Origin of Species one year later, the appearance of which provoked other leading scientists like August Weismann to adopt and amplify Darwin’s perspective. Weismann’s neo-Darwinian theory of evolution was further elaborated, most notably in a series of books by Theodosius Dobzhansky, Ernst Mayr, Julian Huxley and others. In this article we first summarize the history of life on Earth and provide recent evidence demonstrating that Darwin’s dilemma (the apparent missing Precambrian record of life) has been resolved. Next, the historical development and structure of the “modern synthesis” is described within the context of the following topics: paleobiology and rates of evolution, mass extinctions and species selection, macroevolution and punctuated equilibrium, sexual reproduction and recombination, sexual selection and altruism, endosymbiosis and eukaryotic cell evolution, evolutionary developmental biology, phenotypic plasticity, epigenetic inheritance and...

...and does not dissolve in water as well as insoluble in protein.. Chicken feather consists of a central shaft (rachis), barb and barbules. Among the most complex integumentary appendages found in vertebrates and are formed at outer skin layer that produce keratin proteins are feathers. The β-keratins in feathers, beaks and claws — and the claws, scales and shells of reptiles — are composed of protein strands hydrogen-bonded into β-pleated sheets. They are then further twisted and cross-linked by disulfide bridges into structures even more tough than the α-keratins of mammalian hair, horns and hoof. Keratin is a fibrous structural protein of nail, hoof, hair, wool, horn and of the epithelial cells in the outermost layers of the skin. Keratin serve important structural material making up the outer layer of human skin. In addition, it is also the key structural component of hair and nails. Keratin monomers assemble into bundles to form intermediate filaments, which are insoluble, tough and form strong unmineralized tissues found in reptiles, birds, amphibians, and mammals. Feather keratin shows the most prevalent amino acids found in keratin are glycine, cysteine, valine and alanine, but lower amounts of lysine, methionine and tryptophan. Keratin protein is ubiquitous in most vertebrates and invertebrates and has several important cellular and extra-cellular functions that are related to protection and survival. It is the most important biopolymer encountered in animals after collagen...

It also increases the accuracy of Fungal protein prediction by 20% and recall by 4% with AD Tree. In case of Human protein, the accuracy is improved by about 25% and sensitivity about 10% with BF Tree. Performance analysis of NcPred clearly demonstrates its suitability over the contemporary in-silico nuclear protein classification research. 1 Introduction Nucleus, popularly known as the control center of a cell, is the central unit of eukaryotic cells [2]. Unlike other organelles, its function is regulated by two genomes due to the presence of an explicit nuclear genome. It performs a plethora of biochemical reactions like oxidative phosphorylation, Krebs cycle, DNA replication, transcription, translation, etc. In addition nuclei are also involved in apoptosis and ionic homeostasis [3]. Because of their multidimensional utility, nuclear proteins are associated with several diseases, including Xeroderma pigmentosum, Fanconis anaemia, Bloom syndrome, Ataxia telangiectasia and Retinoblastoma [4] etc. Md.

...Ask and Answer Paper: Understanding Prions Ask and Answer Paper: Understanding Prions Steven English Ask and Answer Paper: Understanding Prions 1 As its name suggests, Pasteur's germ theory of disease simply states that microbes are the cause of disease. Though it seems obvious now, it was revolutionary at the time of its inception and is central to our modern understanding and treatment of diseases. It replaced the commonly held and relatively complex 'humoral theory' with a simpler concept that boiled down to a relationship between microorganism and host (“Germ Theory,” n.d.). But as our understanding of the disease process grows with more and more diseases continuing to be discovered, we find that while viruses and microorganisms might be the main cause they aren't the only way in which disease can spread. Prions are one such challenge to this simple germ-disease paradigm. In this paper, the following questions about prion diseases (focusing primarily on kuru and Creutzfeldt-Jakob disease) will be examined: “What are they and what does their discovery mean for our understanding of disease and evolution?” The prion protein (PrPC) is a protein seemingly found in the brains of almost all vertebrate animals which...

...* What Is a Blood Disorder? Bottom of Form Blood disorders are physical conditions that prevent the normal function of blood in the body. A disorder may involve factors that interfere with the production of the individual components found in the blood, such as hemoglobin or blood proteins. The nature of a blood disorder may also include situations where the blood does not coagulate properly, or the blood cells themselves are malformed or infected. There is a wide range of blood diseases known today. Anemia is one of the more common examples of a blood disorder. Sometimes referred to as tired blood, a person who is anemic is likely to have a lack of proteins and other elements in the blood. As a result, the blood cannot carry the needed nutrients to various parts of the body and the individual is likely to feel fatigued more often. Over time, anemia can also have a negative impact on the emotions, as the blood is unable to supply proper nutrition to the brain for the production of chemicals that help to maintain an even mood. Sickle cell anemia is one of the more serious types of anemic blood disorder. In addition to fatigue, a person suffering with this disorder is also likely to experience a great deal of pain. The pain may be localized in one part of the body or migrate to different areas throughout the course of the day. Ad Hemophilia is another relatively common blood disorder. Hemophiliacs suffer with a condition in which the blood lacks the normal ability to coagulate...
