...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 ecology...

...together, so that I could see how each piece, however unimportant the piece seemed, fit together to create a working object. As I progressed in my school life, my interest in applying this in real life increased. It always fascinated me how even the lack of the smallest organism could tamper the ecosystem just like a spring toy that does not work properly if the spring is slightly bent. After Grade 10, I took up pure sciences- Biology, Physics and Chemistry as well as Mathematics and English. My passion for biology was keenly supported by all my chosen subjects. Chemistry helped me understand the molecular structures while Physics and Mathematics helped me understand the dynamics and statistics that we were provided with. Being an avid reader, has led to the formation of many ideas which I feel can be expressed on gaining more insight. A degree in Biological Sciences will help me reach my dream. Earlier this year, three of my friends and I participated in NTU Science Symposium. We had to write a research paper in any field of science. The four of us love biology and felt that we would be able to express our skills and knowledge through the paper and came up with the topic 'External Factors Affecting Bacterial Growth'. The research paper certainly tested our abilities to work as a team. We had to submit the paper in May and all of us had many other commitments apart from the research paper. Like every group has someone to keep all the interpersonal relations intact, this task was an...

...subsequently, the invention of the internet, the science community particularly has had a drastic shift in the scientific publication process. Journals that took months to publish, print and be delivered, are now instantly made available through online websites. Moreover, modernizing resources results in the increase in the available, accessible information for the community. Since the beginning of the century, online science journals have made the scientific community cohesive by providing with the most up to date findings for research being conducted in particular fields as well as all are new ways to “interact” amongst individuals. For this report we have chosen four online resources that provide information on the area of biomolecular biology and neurology, we will enumerate their usefulness to our particular field of interest and their incidence in our future professional careers. In the 1850’s, an Austrian monk Gregor Mendel discovered that he can manipulate plant offspring to breed plants selectively with traits that he wished to see; he cross-bred two tall pea plants and found that the offspring almost certainly expressed the "tall" feature. At the time, the scientific community was ignorant with genetic and DNA comprehension, but Mendel's work would prove to be a precursor to Darwin's evolutionary theory and eventually a foundation for all medical practice performed today. While our understanding of genetics is superb at best, new ideas and practices keep the medical...

...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 of."[3][4] The...

This young adult novel by Laurie Anderson about the 1793 yellow fever epidemic ignited my passion for bacterium and prokaryotic cells. By the time I reached tenth grade I was deeply entrenched in this minuscule world. It was then my biology teacher shared a story with us about the parasite Toxoplasma gondii. It was researchers at the University of Pennsylvania School of Veterinary Medicine that discovered how this parasite crosses the blood-brain barrier. That was the moment that I became aware of the University of Pennsylvania. Since then I have come to realize the in-depth...

Over a long period of time, personality has been researched and studied. Theorist for decades have tried to conclude how much of our genetic make-up dictates who we are, but determining its role in our personality as we grow into adults, has been very controversial. According to the theorist Hans Eysenck, he believes that a biological factor influences our personalities. This paper will take a look at the biological theory of Hans Eysenck and what percentage of biology determines our development as adults. As for me, growing up in a very religious home is all too familiar. My grandfather was a preacher, my grandmother an evangelist as well as my mother. So to everyone else, it was only a matter of time that I was passed the torch of preaching and follow in my family’s footsteps. However, to my surprise, as I began to grow, my growth took me far away from the direction of the church. As an adult, even mid-teens, there was no interest (at the time) to be in church or return. Therefore, I began to question myself, why am I so different? Why don’t I have the same desire to preach God’s word? Why doesn’t it bother me not to be a part of a church? Is it because...

...Biology is a huge subject with many sub branches, application and tools that have helped in the improvement of humanity. Bioinformatics is one of the many Biology branches, that is currently helping in medicine and other areas related to science. One of the ways it is doing it, is by improvement and be able to sequencing DNA (genome). Bioinformatics can be described as a science tool in which use computer technology to analyze, collect, storage, and retrieval of genomic data. There are different methods to sequence the genome of an organism, store and evaluate the information obtained. Sanger and Next Generation Sequencing are the most known methods. Sanger involve several steps, which includes the used electrophoresis, cloning large fragments...

...ecology of life, can be both beneficial as in the decomposition of waste products and harmful in the way that they can cause illness, diseases and even death in animals and humans. The purpose of this study was to identify two unknown organisms from a single mixed culture broth by using biochemical tests and procedures learned in the microbiology laboratory and the Biology 2420 Laboratory Manual for Microbiology by Mary Hearron, Ed. D. and Brenda Deming, Ph. D., M, T. (ASCP) (1). Materials and Methods On November 5, 2014, unknown #13, a mixed broth containing two unknown organisms was obtained from an arrangement set up by Dr. Deming. Each student chose an unknown from the arrangement and was not assigned a particular number to ensure that the project was blind and not rigged in any way. From that point, streak plates and biochemical testing was conducted to determine, the A and B unknowns. All media and biochemical tests were labeled with the name date, time, unknown A or B, and the test being conducted to eliminate confusion and errors. All procedures used unless otherwise noted were taken directly from the Biology 2420 Laboratory Manual for Microbiology by Mary Hearron, Ed. D. and Brenda Deming, Ph. D., M, T (ASCP) (1) and verified with A Photographic Atlas for the Microbiology Laboratory, 4th Edition by Michael J. Leboffe and Burton E. Pierce (2). Once unknown #13 was obtained, the first procedures performed was labeling and streaking a Tryptic Soy Agar (TSA) plate, a media...

Discuss how physical anthropologists examine/investigate evolution Paleoanthropology is a branch of paleontology that falls under physical anthropology. Paleoanthropologists study extinct primates and fossils. They use these examinations to further investigate the evolution of humans. They examine ancient humans, like the anthropoids. Anthropoids are considered humans closest relative and have been linked to human evolution (Coyne, 2009). 3) Find at least one outside source related to your answer for Question 2 (e.g. the genome project for DNA).

...PUT AN END TO Animal Abuse Animal testing is animal cruelty. I am an animal lover and also the adopted mother to a short hair tabby named Dutch. When I look at my cat I see a living being. In feel his energy, I feel a soul. Why is it that their lives are looked upon as less valuable than ours? People who run experiments and tests on animals should be punished the same as those who mistreat and/or are cruel to animals. YES, I believe all animal testing should be banned in the United States. These animals do not have the answers. They cannot even speak for themselves to express how they feel. They are in no position to give their consent to have experiments preformed on them. These animals are living creatures as we are and they should be treated as such. They deserve a loving, caring, and safe place to call home. As I researched this topic I came across a lot of material about the testing of cosmetics on animals. I guess people are blind to the fact that it is not just cosmetics that are tested on animals but household products and many other substances as well. “In the cosmetics and household products research, painful experiments are carried out on hundreds of thousands of animals every year around the world, including dogs, rabbits, pigs, mice, rats, guinea-pigs, fish and birds. This includes tests for skin or eye irritation, skin sensitization (allergy), toxicity (poisoning), mutagenicity (genetic damage), teratogenicity (birth defects), carcinogenicity...
