Heredity and the Environment Formal Lab

Introduction:
The environment’s effect on genotypes can sometimes affect phenotype expressions, which are traits that are inherited. Phenotype is the physical appearance of a trait, whereas Genotype is the genetic makeup of an allele. A phenotype can be turned off by environmental factors. In this case, the seeds. Some of the seeds are not geneticlly albino, but because the environmental factor of the lack of sunlight, the seeds didn’t show their real phenotypic expression thus made the seeds “albino”. The ability for an organism to respond to its environment is determined to a great extent by its genotype. As some of the seed has chlorophyll in their genes …show more content…
First, we sprinkled the tobacco seeds evenly in two petri dishes, one is clear and the other is opaque. Then the dish was labelled with the student’s initials and stacked with the opaque dish on the bottom, and was placed on a tray under a lighted window. So the sunlight could come in contact with the seeds in the clear dish, and the dishes were checked daily until they germinated within 7 days. Once the seeds have germinated, the number of green and albino seedlings were recorded on a supplied data table. Then the lids of the two dishes were switched, the original opaque dish was stacked on top and placed under sunlight. After 24 - 48 hours, the seedlings in the opaque dish were counted and …show more content…
The data in the clear dish before switch shows a 2:1 ratio of 83 : 47, it also shows the expected value of the green seed before switching is 97.5 but the observed value is 83. Whereas the the expected value of the albino seed before switching is 32.5 but the observed value is 47 which has a difference of 14.5 seeds in expected and observed values of in both green seeds and albino seeds. The data in the clear dish after switch shows a 3:1 ratio of 103:35, it also shows that the expected values matches the observed values. A 3:1 ratio in the clear dish is what we expected in the hypothesis.
For the data in the opaque dish before switch shows a 0 :1 ratio of 0 : 185, it also shows the expected value of the green seed before switching is 138.75 but the observed value is 0. Whereas the the expected value of the albino seed before switching is 46.25 but the observed value is 185. The data in the opaque dish after switch shows a 2.5:1 ratio of 139 : 55, it also shows that the expected values and the observed values has a minor deviation.

History of Psychology

...UNIT 1: THE DEFINITION AND HISTORY OF PSYCHOLOGY QUESTION #1.1: What is the definition of psychology? Psychology is best defined as the "scientific study of behavior in humans and animals." Behavior is what people and animals do: e.g., what a person says about last night's dream, and how long it takes a rat to run a maze. You might think that psychology was the "study of the mind" due to the fact that the prefix psyche is Greek for mind, soul, spirit, and the suffix ology refers to the study of something. Almost a hundred years ago, John Watson decided that psychology should be a science: not just a vague and introspective reflection on our own thoughts and feelings. Watson urged that psychology be defined as the scientific study of behavior. Since about 1920, most university psychologists have accepted Watson's definition. So, think of psychologists as scientists who study behavior. Introspection was the first technique for studying the mind There are some terms related to psychology that are frequently confused with it. Psychiatry is a branch of medicine specializing with mental disorders. Psychiatrists are medical doctors, and have been through medical school, an internship, residency training, and board certification as specialized physicians. The letters M.D. usually appear at the end of the name. The letters at the end of the name of a psychologist may be 1 Ph.D., Ed.D., or Psy.D., and so it may be appropriate to address a psychologist as...

...PART 1 THE STUDY OF HUMAN DEVELOPMENT R esearching the process of human development across cultures provides us with an opportunity to improve the human condition as well as, hopefully, to acquire the knowledge needed to optimize life satisfaction. We therefore begin with an overview of how diverse social science and life science researchers (collectively known as developmentalists) approach the monumental task of studying humans over the course of the life span. Our discussion includes the goals of the scientific community, the recognized framework for studying the life span, what aspects of development warrant extensive examination, and what scientific methods are used to conduct research with humans. Chapter 2 discusses the main developmental theories over the past 100 years, when social scientists, biologists, and chemists focused on studying discrete aspects of human development. Earlier introspective methods about subconscious experience and contemporary measurable evidence about microscopic genetic codes, neurons, and hormones all contribute to our understanding of the human condition. Contemporary researchers are focusing on how to integrate scientific findings and theory from across cultures into a more meaningful whole about human development. CHAPTER 1 Introduction Critical Thinking Questions 1. Developmental change takes place in three fundamental domains: physical, cognitive, and emotional-social. Which domain has been most important for...

Current Trends in Nutrition

...Current Trends in Nutrition The Role of Omega-3 Nutritional Supplements in Treating Childhood Dyslexia Dyslexia is a literacy disorder whose exact cause remains unknown. It does not affect IQ or other cognitive function, but can profoundly impair reading ability. It is believed that heredity plays a role, and several studies have sought to determine whether degree of deficiency of fatty acids in the diet could also be a contributing factor ( Richardson AJ, 2000). Dyslexia has been linked to clinical signs of fatty acid deficiency in adults, so the question of treating developmental dyslexia in children with fatty acid supplements has been raised as a possible safe and effective treatment (Taylor KE, 2000). There is a growing trend among holistic practitioners and drug manufacturers alike, to develop and market supplements to treat dyslexia, and as the disorder has such far-reaching consequences in academic success, self-esteem, and social interaction for those who suffer from it, the market is quite receptive to new treatment approaches. (Evans R 1999) Given that development of nutritional dyslexia treatment is a relatively new endeavor in the scientific community, review of current and recent research on the matter is appropriate. Evaluating proposed treatments and commercially-prepared nutritional supplements will be more effective with a background understanding of the issue. Research studies have reported that dyslexic children are deficient in body stores of...

Epis' Paper on Positivism

...-“Strauss versus Brains and Genes or the postmodern vengeful return of positivism.” This essay first started as an answer to what I deemed very problematic, i.e. the disputation which I found in bad faith (un-authentic to use a philosophical term or an existentialist term), of the mediatic, dashing Harvard cognitivist/linguist, Steven Pinker, in his article “Neglected novelists, embattled English professors, tenure-less historians, and other struggling denizens of the Humanities, Science is not your Enemy—a plea for an intellectual truce,” (The New Republic--August 19). Then the counter-arguments against Steven Pinker’s conception of the “human animal” developed into an essay arguing that the New Positivism, not science, or technology per say, was the enemy of humanism and its avatars as such. The point is not to become a postmodern anti-scientific Luddite. Genomics are changing the world in ways we barely imagine yet and will re-define what it means to be human (a becoming already imagined by science fiction writers, social critics and critical thinkers such as the feminist Donna Haraway with her “Cyborg”). The point is also not to turn “anti-brainiac.” Without a brain we would become vegetative, a vegetal…, i.e. a purely “natural body,” a “zombie.” If we make use of this “computer” allegory which is an analog but not a homologue, and which is used ad nauseam used by psycho-biologists, without a hard-drive there is no software. But is this a reason to say that the software...

...Section A: Basic Microbiology 1 SCOPE AND HISTORICAL DEVELOPMENTS IN MICROBIOLOGY “Science contributes to our culture in many ways, as a creative intellectual activity in its own right, as a light which has served to illuminate man’s place in the uni-verse, and as the source of understanding of man’s own nature” —John F. Kennedy (1917–63) The President of America The bacterium Escherichia coli INTRODUCTION AND SCOPE MICROBIOLOGY is a specialized area of biology (Gr. bios-life+ logos-to study) that concerns with the study of microbes ordinarily too small to be seen without magnification. Microorganisms are microscopic (Gr. mikros-small+ scopein-to see) and independently living cells that, like humans, live in communities. Microorganisms include a large and diverse group of microscopic organisms that exist as single cell or cell clusters (e.g., bacteria, archaea, fungi, algae, protozoa and helminths) and the viruses, which are microscopic but not cellular. While bacteria and archaea are classed as prokaryotes (Gr. pro-before+ karyon-nucleus) the fungi, algae, protozoa and helminths are eukaryotes (Gr. eu-true or good+ karyon-nucleus). Microorganisms are present everywhere on earth, which includes humans, animals, plants and other living creatures, soil,water and atmosphere. Microorganisms are relevant to all of our lives in a multitude of ways. Sometimes, the influence of microorganisms on human life is beneficial, whereas at other times, it is detrimental.

But false views, if supported by some evidence, do little harm. (Charles Darwin, The Descent of Man and Selection in Relation to Sex, 1871)2 Since its publication in 1995, Daniel Goleman’s Emotional Intelligence: Why It Can Matter More than IQ has been the flagship of a fleet of books that Goleman has authored or co-authored, and the foundation text of a world-wide movement that claims that what has been universally regarded as intelligence is merely one type of intelligence – cognitive intelligence – and is not as important as another type of intelligence – emotional intelligence. As the dust jacket of Emotional Intelligence proclaims, it is, “The groundbreaking book that redefines what it means to be smart.” In this document, I will analyze every book and article that Goleman adduced to denigrate the importance of cognitive intelligence, and even more, the tests that measure it. I will demonstrate that not one of them says what Goleman claims it says, and many say the opposite.3 No one denies that emotional strengths and social abilities often contribute to social and occupational success. But Goleman knew two crucial facts about them that he did not tell his readers.
