South University Online

Over the past two hundred years there have been a significant number of discoveries that are notable. Some of the most notable discoveries are the cure for syphilis in 1909, the discovery of insulin in 1922. In 1922 penicillin was discovered, the nucleus of an atom was found to be made of protons and neutrons in 1932. Chemotherapy for the treatment of leukemia was developed in 1950. The building block of life, DNA, was discovered in 1953 and then one year later the first kidney transplant that was successful is noted. And most notable in 1997 scientist were successfully able to clone “dolly” the sheep. From the years of 1960 to 1994 the life expectancy increased from forty years to an astounding fifty years. During the same time period the infant mortality rate dropped by forty percent. Also during this time period the percent of population with safe drinking water went from twenty-four percent to forty-two percent. Throughout our time during this Biology class the most interesting topic that was covered was evolution, in my opinion. I was one of those people that was very closed minded about the theory of evolution. I am not a religious person, so I did not have the thought of some higher power creating all organisms, I just did not know what I thought, to be honest. Now that I was able to do research on my own, I do believe that evolution is how organisms came about. It is and will always be a very controversial topic, but if we would all look at facts we can agree that some parts of evolution are true. The same for me I am not religious, but I don’t doubt that a man named Jesus walked around on earth. Since evolution was the most interesting part of my studies I will first be looking at some recent discoveries regarding...

Human Behavior

...Many people overlook the significance of the biological influence on human behavior. They fail to realize what a big impact our biology as humans have on characteristics, views and behavior. Mutations in our biology and neurological systems are the cause of many of the psychological disorders that people suffer today. Our environment as well as the way we think and feel influence our everyday behaviors. These thoughts and feelings are processed by neurons in the brain and nervous system. Neurotransmitters in our brain and nervous system control all of our functions. When these neurotransmitters don’t function properly, such serotonin which controls sleeping, eating, mood, pain and depression, psychological disorders may arise. Molecular genetics seeks to identify specific genes that are associated with behavior and psychological disorders (Feldman, 2009). Research in molecular genetics has helped to identify genetic markers that are linked to many psychological disorders such as schizophrenia and depression. Research into this field may help develop earlier detection and treatment for these disorders and may also lead to effective gene therapy that can be used to potentially treat these same diseases. Aside from psychological disorders that can be genetically identifiable, physical characteristics that result from our biology and genetics can also affect us psychologically. Although environment also plays a role, physical characteristics such as weight, tone...

Why Biology

...Human beings have reached the top of the food chain due to evolution and they have evolved to not only become intelligent but also answer the previously unanswered questions of the universe. I want to be able to study these fascinating creatures and figure out how they have arrived to this point by examining their genes. Apart from the main science subjects (biology chemistry and math) I have also taken economics at AS level as I have always been fascinated by what funds a country and how money keeps the world running. I also realized the importance of money when it comes to scientific research and how it can influence some findings. I also look forward to apply the statistical formulas I learned in math (S1 and S2) in the course. My interest in biology was also consolidated by reading the books such as ‘Genome’ by Matt Riddley and ‘The Man who mistook his wife for a hat’ by Oliver Sacks. Although I found it quite interesting how the writer describe the genome as a language consisting of four letters I believe that it is far more complicated than that. There are still things about this language that we don’t know and these secrets could be the solution to certain problems ( eg. Reduce mutations caused by jumping genes that make certain genes dysfunctional.) Oliver Sacks description of neurological diseases as well as his interaction with his patients was quite inspiring. Certain malfunction in the Occipital lobe of the brain could lead to a person mistaking his wife’s......

Science a N D Human Welfare’

...SCIENCE A N D HUMAN WELFARE’ I BIOLOGY AND MEDICINE M Y SUBJECT this afternoon is “Biology and Medicine,” but I think a more accurate wording would be “Medi- cine and Other Phases of Biology,” for to my mind Medicine is a branch of Biology. Webster’s Dictionary defines medicine as the science and art dealing with the prevention, cure, or alleviation of disease. Biology is the science of life, Disease might well be defined as life out of balance, and is in a strict sense a biological process. Whether it be an attack by microorganisms, or improper functioning of glands, or congenital misformation or maladjustment, or injury by poison or bullets, disease processes are in the last analysis nothing more than cells, tissues, or organs that have suffered injury and so not only fail to perform their normal functions but in most cases interfere with the normal functions of other parts, more often than not of the entire body. Of the two great divisions of medicine dealing respectively with treatment and with prevention, the former is much the older. It is far easier to observe the effects of treatment on a person suffering from a malady than it is t o understand why someone else escaped it. Some knowledge of curative or alleviative medicine was possessed by our cave-dwelling ancestors; in fact, it is instinctive in many lower animals. It gradually grew up as a sort of folklore from a slow process ‘Public lectures delivered a t the Rice Institute on Sunday afternoons in the......

Gender and the Biological Sciences

...Gender and the Biological Sciences Kathleen Okruhlik –Philosophy of science professor and Dean of Arts at Western. –This paper was published in 1994. –Offers a sophisticated feminist critique of the philosophy of science. Feminist critiques of biology are politically important Because biologically determinist arguments are often cited to ‘explain’ women’s oppression. E.g., genes, hormones, and evolution ‘explain’ why it is ‘natural’ for women to function in a socially subordinate role, why men are smarter and more aggressive than women, why women are designed to be homebodies, and why men rape. Thus, promoting a more equalitarian and just society is useless or counterproductive. Feminist critiques of biology are also epistemically important. Because of the status of biology among the sciences. Social sciences are often dismissed as not real sciences, so to criticise them is not as effective. But biology is not easily dismissed as a pseudo-science, and so to criticise it can teach us something about the nature of science (i.e., its rationality, objectivity, degree of insulation from social influences, etc.) Some cases studies: (1) gender and reproduction The Sleeping Beauty/Prince Charming model of the relationship between egg and sperm in reproduction. –Just as women are seen as passive and men as active, the egg and sperm are traditionally assigned these roles. –The sperm is the one doing all the work to get to the egg and penetrate it, while the egg......

What Is Biochemistry

...What is Biochemistry and why you should study it? Biochemistry or sometimes we called it as biological chemistry is defined as a scientific study of the chemistry of living organisms, especially the structure, the behavior of a living thing and the function of their chemical component such as proteins ,carbohydrates, lipids, and nucleic acids. Many of these molecules are complex molecules called polymers, which are made up of monomer subunits. Most people consider biochemistry to be same with molecular biology. Nowadays, biochemistry has become the root for understanding all biological processes. It has provided widely explanations for the causes of many diseases in humans, animals and plants. As a student, we should study it because it give to us many kind of knowledge on understanding the biological processes which are happen around us in every single minutes in our life. Since biochemistry is very important, we must study it to know how this biochemistry contributed for the sustainable of tomorrow in the main field of medicine, agriculture and industry. Biochemistry is applied in many health field such as dentistry, medicine and veterinary medicine. For example, in the field of medicine, biochemistry have contribute in the clinical study to maintain and to give a better and healthy life to the population of human all around the world. This have been done by the scientist on how they use biochemistry to diagnose and control the spreading of diseases, product a......

What Begins People’s Discovery of Science?

...Topic: What begins people’s discovery of science? Thesis: “Hypotheses non fingo,” Newton confidently claimed. Therefore, he arbitrarily excluded the “hypothesis” from the experimental philosophy. Affected by him, more and more remarks neglected the importance of the “hypotheses” since then. As a result, it becomes a common view that discovery should proceed from analytic methods stricto sensu. Then, what is the real definition of hypothesis in Newton’s opinion ? Will he believe in intuition? Therefore, I will try to explain the definition of both “hypothesis” and “intuition”, and then attach significance to the “intuition” to show how the intuition begins a new discovery of science and struggle to prove that sometimes, the intuition can be a quite strong power to lead us to reach our confirmations. Outline: 1. The moment when I realize the importance of the intuition (Faraday) 2. The definition of hypothesis and intuition 3. The supporter- Einstein (using his examples as detailed ones) 4. The other famous successful discoveries in four different fields: Physics, Chemistry, Biology, Geography (describing the main story of each example) 5. How should we treat the intuition? What should we do after the intuition? 6. The conclusion includes 1) The importance of the intuition, 2) The significant role it has acted in the history of science, 3) Its efficiency of finding a certain answer, 4) An interesting analogy to show the role of......

Biology Current Events Assignment

...Biology Current Events Assignment Omar Patel May 6th, 2014 Scientists Discover Cosmic Factory for Making Building Blocks of Life September, 15, 3013 Zita Martins, Mark C. Price, Nir Goldman, Mark A. Sephton & Mark J. Burchell In the article it states that when icy comets collide into a planet, amino acids are created. These are the building blocks of life and from the amino acids. This means that amino acids can be created anywhere in the world with these conditions. The article also states that a couple of moons of Saturn have the perfect environment for creating amino acids if a comet hits them. The researchers stated that the comets crash into the ground, which create shockwaves that create amino acids. The scientists figured this out by using a special gun that replicates the crash of a comet. This article is related to science/biology because it helps us understand how life first formed on Earth. I think this discovery will benefit everyone around the world equally because a common question usually asked is how the world was created in a scientific sense. Scientists will be very happy with this information because it would help them keep researching for ideas to satisfy peoples questions related to this topic. Sep. 15, 2013 — Scientists have discovered a 'cosmic factory' for producing the building blocks of life, amino acids, in research published today in the journal Nature......

...Biology From Wikipedia, the free encyclopedia For other uses, see Biology (disambiguation). Biology deals with the study of the many varieties of living organisms. Clockwise from top left: Salmonella typhimurium, Phascolarctos cinereus, Athyrium filix-femina, Amanita muscaria, Agalychnis callidryas, and Brachypelma smithi Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy.[1] Biology is a vast subject containing many subdivisions, topics, and disciplines. Among the most important topics are five unifying principles that can be said to be the fundamental axioms of modern biology:[2] 1. Cells are the basic unit of life 2. New species and inherited traits are the product of evolution 3. Genes are the basic unit of heredity 4. An organism regulates its internal environment to maintain a stable and constant condition 5. Living organisms consume and transform energy. Subdisciplines of biology are recognized on the basis of the scale at which organisms are studied and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions of systems of biological molecules; cellular biology examines the basic building block of all life, the cell; physiology examines the physical and chemical functions of the tissues, organs, and organ systems of an organism; and......

Biology Introduction

...including their structure, function, growth, evolution, distribution, and taxonomy.[1] Modern biology is a vast and eclectic field, composed of manybranches and subdisciplines. However, despite the broad scope of biology, there are certain general and unifying concepts within it that govern all study and research, consolidating it into single, coherent fields. In general, biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the synthesis and creation of new species. It is also understood today that all organisms survive by consuming and transforming energy and by regulating their internal environment to maintain a stable and vital condition. Subdisciplines of biology are defined by the scale at which organisms are studied, the kinds of organisms studied, and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biologystudies the complex interactions among biological molecules; botany studies the biology of plants; cellular biologyexamines the basic building-block of all life, the cell; physiology examines the physical and chemical functions oftissues, organs, and organ systems of an organism; evolutionary biology examines the processes that produced the diversity of life; and ecology examines how organisms interact in their environment.[2] HistoryThe term biology is derived from the Greek word βίος, bios, "life" and the suffix -λογία, -logia, "study......

...Inquiry Method and Student Academic Achievement in Biology: Lessons and Policy Implications Jacinta A. Opara European School Science Project, 18140 Granada, Spain Abstract: Three research questions with null hypotheses guided the study with the aid of a quasi experimental research design. These students were randomly assigned to two groups (treatment and control group). Treatment group were those taught biology using the sensitized inquiry teaching method while conventional method (lecture) was used for the control group. (1) Biology Achievement Test (BAT) was developed on the following units in biology, flower pollination, muscle structure and function and seed germination. All these were drawn from anatomy and physiology of flowering plants and animal physiology in the biology textbook of SS1, to measure the initial and terminal academic achievement of the students. (2) Lesson notes were prepared on the above mentioned units using the inquiry teaching method and the conventional method using a pre - test, post - test experimental treatment. Thus, it is the contention of the author that the inquiry approach would enhance students’ achievement in biology, hence the thrust of this study. Key words: Inquiry teaching method Conventional method INTRODUCTION Achievement Biology Gender Location explanations from their observations (evidence) by integrating what they already know with what they have learned.
