...Richard Ching Biology 141 Exam 1 Study Questions 1-15 1. What is the difference between an hypothesis and a scientific Theory? Between an hypothesis and a prediction? What kinds of hypotheses are useful for scientific investigations that try to explain the natural world, and which are not? Give one or more examples of hypotheses that are and are not scientifically useful. A scientific theory is an explanation for a broad class of phenomena or observations, whereas a hypothesis is a testable statement to explain the workings of a particular scientific theory. In other words, a hypothesis aims to find out how a phenomena occurs. What distinguishes a hypothesis from a prediction is that a prediction is simply a part of a hypothesis, and is an observable or measureable result that must hold true if the hypothesis is correct. A hypothesis is useful to a scientific investigation in the case that it can be tested and have results gathered from experimentation or observation, while hypotheses that cannot be tested and concluded upon are not useful. An example of a useful hypothesis is the question of whether or not cramming increases test performance when compared to consistent studying, and an example of a hypothesis that is not scientifically useful would be the question of whether God truly exists. 2. Two of the greatest unifying ideas in biology (i.e., concepts that account for and are consistent with a very large number of observations) are the Cell Theory, and the Theory...

Human require approximately fifty nutrients for growth and cell maintenance and repair. These nutrients are divided into six classes: proteins, lipids or fats, carbohydrate, vitamins, minerals and water. A diet consisting of a relatively equal combination of terrestrial mammals, birds, shellfish, fish and plant foods would lead to healthier individual than would a diet based solely or primarily on one type of animal food such as terrestrial mammals. Our physiological needs provide the basic determinants of food choice. Humans need energy and nutrients in order to survive and will respond to the feelings of hunger and satiety. Hunger and satiety are the result of complex physiological processes, e.g., blood depletion of nutrients, empty stomach. As food is eaten satiation...

...The following is a modified version of the AMCAS MD/PhD essay. Biomedical research has been an interest of mine for as long as I can remember. The concept of tackling and solving biological mysteries has always been greatly appealing to me and I found the fact that work done on something as microscopic as cells and proteins could be used to cure visible ailments of disease to be astounding. Throughout my primary education, I relished each opportunity to conduct experiments in class, and I eagerly anticipated the day when I could finally contribute towards understanding disease and improving human health myself. My first foray into scientific research occurred during the summer of my second year in high school, from June to August, 2012. As part of the NIH’s summer internship program, I joined Dr. Yingzi Yang’s laboratory under the National...

...disorder which according to the National Institute for Health and Care Excellence (NICE, 2009) guidelines, affects one per-cent of the UK population. Schizophrenia can be classified as an overall category for the mental illness; however, diagnostic tools such as the International Classification of Diseases (ICD-10) and the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) reveal the variations of the psychiatric disorder. This essay will explore and focus on one specific subtype of the mental illness. Paranoid Schizophrenia. According to T.Davies and T.Craig (2009, p45), Paranoid Schizophrenia is one of the most common subtypes of the psychotic illness which affects the individuals variation of emotion, thinking and behaviour. Through extensive research, this essay will uncover the definition of paranoid schizophrenia, its manifestations and possible causes. Key issues such as symptoms, epidemiology, prevalence, co-morbidity, prognosis, treatment and interventions will also be critically reviewed and discussed. Lastly, this essay will also analyse guidelines, policies and regulations that influence interventions and the effects of paranoid schizophrenia on the individual, their families, carers and friends. There are various subtypes of schizophrenia such as undifferentiated, residual, simple, other and unspecified schizophrenia with the three most common being Paranoid, Hebephrenic and Catatonic Schizophrenia (C.Gamble and G.Brenan 2006, p100). Prior to the diagnosis...

...an individual. Unit introduction This unit builds on learner understanding of the principles introduced in Unit 5: Fundamentals of Anatomy and Physiology for Health and Social Care. Improvements in the diet of individuals are increasingly being recognised as a significant factor in maintaining, or effecting improvements, in overall health. It is therefore important that people working in the health and social care sectors, or those who are responsible for the wellbeing of others, have a good understanding of nutrition and diet. This unit gives learners an understanding of nutrition from a science-based perspective and of the role that food plays in social contexts. The unit may also provide useful underpinning knowledge for the study of food hygiene and practical culinary skills. Learners will explore concepts of nutrition using the language of nutritional science. Different aspects of nutritional health will be defined and routine ways of measuring this explored. Other aspects of nutritional data will involve describing the general principles on which nutritional requirements are determined in the UK and how information on the nutrient content of foods can be retrieved. Learners will also explore how the nutritional value of foods may be affected by food processing. The function and sources of the main nutrients will be investigated in relation to the contribution they make to the healthy...

...Nick Montesano Buss 200 Administrative Law Essay The College Of New Jersey Dr. Laura Sanders 9/29/30 A National Dispute In the past decade there has been an increased controversial view of tobacco, alcohol, and marijuana. People have been divided on how to regulate these products in the market, causing much governmental controversy. There have been many groundbreaking and unprecedented court cases that have been shaping the public policy on which these substances stand on. These substances have an immediate and perilous effect on the health of all human beings. Tobacco is the leading cause of preventable death in the United States, alcohol causes impaired judgment and in turn causes people to do things that affect their health physically and emotionally, and marijuana has almost the same effect as alcohol. (New England Law) Health is the ultimate concern when studying these three substances, which would lead to the Family Smoking Prevention Act to survive the Hudson Test. The Granholm case would lead one to believe that states cannot discriminate against outsiders from sales, and the medical exceptions for marijuana are valid on the fact that it has a medical advantage to some citizens. I strongly believe that the federal government has a right to regulate certain aspects of these substances based upon the danger posed to the health of citizens. This paper will discuss certain court cases that shape my opinion for every substance....

...The aim of this essay is to explore an acute deterioration in the health of an adult I have encountered during a clinical placement, in an acute care setting. The essay will begin with a definition of acute care, followed by the introduction of my patient and predisposing factors. This essay will include an explanation of the significant pathophysiological changes and related clinical manifestations and a critical analysis of the nursing interventions implemented during the acute episode of care, focusing on holistic care, rationale and evidence base. It will then describe the actual deterioration in the patient’s condition, and discuss the nurse’s role in the recognition and assessment of the actual deteriorating condition following the trusts policies. Assessment tools, monitoring, detecting and reporting will be considered. Finally this essay will include a discussion of the importance of multidisciplinary team collaboration in the diagnosis and provision of care during the acute episode, and a discussion on whether the deterioration could have been prevented by identifying any areas of practice which could change in relation to evidence based practice. For the purposes of privacy and confidentiality, in accordance with NMC (2008) code of conduct, the name of the patient will be changed to Peter and the placement area will remain as an acute care setting. According to McFerran (2008) the term “acute” is described as a disease of rapid onset, severe symptoms, and brief duration...
