ABO blood grouping system
According to the AB0 blood group system there are four different kinds of blood groups: A, B, AB or 0 (null). Blood group A
If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma. Blood group B

If you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma. Blood group AB

If you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma. Blood group O

If you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma. Rh factor blood grouping system

Many people also have a so called Rh factor on the red blood cell's surface. This is also an antigen and those who have it are called Rh+. Those who haven't are called Rh-. A person with Rh- blood does not have Rh antibodies naturally in the blood plasma (as one can have A or B antibodies, for instance). But a person with Rh- blood can develop Rh antibodies in the blood plasma if he or she receives blood from a person with Rh+ blood, whose Rh antigens can trigger the production of Rh antibodies. A person with Rh+ blood can receive blood from a person with Rh- blood without any problems.

...Assignment 1: Biology Article Cinthya Jacobo Professor: Dr. Francie Coblentz Introduction to Biology: SCI115 11/08/2015 The article “Therapeutic Cloning, and stem cell Research” by Gena Smith is about how we can extract stem cells from replicated human embryos and use them for medical and therapeutic purposes. The stems cells are perfect because they are what the article calls “master cells” which with the help of science, can be manipulated to become anything from brain cells to kidney cells. The article also revolves around the amount of controversy over the issue of cloning. The article mostly reviews the medical side of cloning rather than the reproduction side which can one day lead to the cloning of individual people. The article has high hopes for the potential use of cloning stating that “Down the road, scientists believe it will be possible to create complicated structures such as blood vessels, liver tissue, and whole kidneys. In fact, ACT scientists have already succeeded in building tiny cow kidneys that could be used for kidney transplants. It isn't hard to envision, Lanza says, a future where pretty much any kind of organ or tissue could be engineered to replace those damaged by age, injury, or disease.” Overall, this new study of cloning could help clone new body tissues which can help regulate, maintain and potentially replace importance body organs that could then lead to the salvation of millions of lives.

...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 field in constant progression. "Gene Editing Could Make Pig-to-Human Organ...

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 spring...

Model Organism

...Model Organisms Model organisms are very important to the scientific community. They are primarily used as a standard for comparison to other organisms. If a model organism is recognized then the organism can be useful for many different fields of research. Rice (Oryza sativa) is a model organism that has been introduced and has several essential attributes. When using a model organisms some qualities that should be chosen are a short life cycle, small adult size that makes it easy to grow in a small space, small genome that is well described genetically, high reproductive outcome, already have a large assembly of mutants, and be able to out cross or be self-fertile. When looking for a model organism consideration has to be taken into account for a few things too. Some of the benefits can become a hindrance. In 2010 a new model organism for studying C4 photosynthesis was suggested, a grass (Setaria viridis), by Brutnell et al. S. viridis is a C4 photosynthesis plant. Because of the C4 functions, it will be useful to aid in further research, with having its genome sequencing known, in comparison to other organisms that are not C4 plants. By having these qualities it makes it a good model organism. Some of these good attributes include its life cycle length. In short-day growth conditions it can be grown to full maturity in about six weeks. As an adult the plant is relatively short, less than 10 centimeters and takes up very little space about 50 plants can be grown in one...

Feasibility of Sweat as a Gas

...HISTORY OF BIOLOGY Though biology is generally regarded as a modern science with late origins in the early to mid-nineteenth century, it drew on varied traditions, practices, and areas of inquiry beginning in antiquity. Traditional histories of biology generally target two areas that merged into modern biological science: medicine and natural history. The tradition of medicine dates back to the work of ancient Greek medical practitioners such as Hippocrates of Kos (b. 460 B.C.E.) and to figures such as Galen of Pergamum (c. 130–c. 200), who contributed much to early understanding of anatomy and physiology. The tradition of natural history dates back to the work of Aristotle (384–322 B.C.E.). Especially important are his History of Animals and other works where he showed naturalist leanings. Also important is the work of Aristotle's student Theophrastus (d. 287 B.C.E.), who contributed to an understanding of plants. Aristotle and Theophrastus contributed not only to zoology and botany, respectively, but also to comparative biology, ecology, and especially taxonomy (the science of classification). Both natural history and medicine flourished in the middle ages, though work in these areas often proceeded independently. Medicine was especially well studied by Islamic scholars working in the Galenic and Aristotelian traditions, while natural history drew heavily on Aristotelian philosophy, especially in upholding a fixed hierarchy of life. The Roman naturalist Caius Plinius Secundus...

Biology Article

...Biology Article Isaac Ayers Professor Carol Hoban SCI115012VA016-1136-001 Introduction to Biology August 2, 2013 * The title of the article that I have chosen for this assignment is “The Era of Memory Engineering Has Arrived”. The article begins by explaining a basic plot of a sci-fi movie in which the main character has had his memories altered by scientists using electrode caps. The article then goes into detail about how a new set of experiments, led by MIT neuroscientists Steve Ramirez and Xu Liu in Susumu Tonegawa’s lab, shows that by using a stunning set of molecular neuroscience techniques. Scientists have captured specific memories in mice, altered them, and shown that the mice behave in accord with these new, false, implanted memories. The scientists needed a way of labeling neurons that were active during a specific experience, and a switch to make them work. It has been found that by using by using the molecule Channelrhodopsin, in already genetically modified mice. Scientists could see recent events that had been recorded to specific brain cells in those mice (Castro 2013). The article then states how with the use of doxycycline, the scientists were able to turn off the labeling or recording process of the experiment. This is important because the scientists were able to label memories in specific times and places. Once the scientists had labeled a memory to the mice, and were able to re-awaken that memory by using light that was shone...

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 head...

Politics

...natural sciences is perhaps the most heated of debates and research into neurotheology such as the existence of the ‘god spot’ shows how vast the subject is. The subject encompasses many of the life sciences and would allow me to gain knowledge of several different disciplines. Combining knowledge of physiology from biology and with the structure of substances learnt in chemistry provides me the rigorous scientific background that is crucial in the neuroscience course. My understanding of molecules and chemical concepts developed in ‘A’ Level Chemistry will prepare me for this degree as the same knowledge can be applied to understand how simple neurotransmitters can impact on human behaviour. In class, we undertook a module called “What’s in a medicine?” where we learnt about the importance of medicines in curing diseases. This entire unit focuses on the mechanisms of action and the clinical significance of drugs such as aspirin or penicillin. This unit links well with the pharmacology aspects of the neuroscience degree as I believe that the knowledge I have gained thus far in this topic will prepare for the concepts introduced at university level. The human biology aspect of the neuroscience degree is an area that intrigues me the most as learning the mechanisms of some of our most complex systems is something I find fascinating and highly enjoyable. Learning about the process of photosynthesis in greater detail was exciting to me as it highlighted how many complex processes...
