Biology
Artificial or Real?
The heart is in the center of the body and is the most vital organ in the body and you cannot survive without it. In the stressful environment, lots of strain is put in your heart, which leads to many heart diseases such as a heart attack, leaky valves, blocked coronary arteries causing the demand toward scientific developments to produce more developed artificial hearts and replacement of heart valves to increase.
Though out the years, science has evolved enormously and this helps the people with heart diseases, which currently affect more than 100 million people around the world. Biologists and other scientists have come up with a solution to solve the problem; they have invented artificial hearts and pacemakers to buy time for a patient to receive a real heart from a deceased donor. In 1963, the first artificial heart was made and in 1982, the first artificial heart was implanted in a human. But these implantations did not completely alleviate patients’ suffering. He had to have received an implantation of the heart valves only survived for 112 day. He was unable to go anywhere and was put on a severe bed rest and was in a severe pain until his death. After many technological developments in the medical science, artificial heart technology was improved further and has been put to more people’s usage.
The human body needs oxygen in order to live. The circulatory system is responsible for filtering oxygenated blood and deoxygenated blood from the body. Blood entered the heart through two veins, the superior vena cava and the inferior vena cava. Both of these veins sent de-oxygenated blood into the right atrium, which then went to the right atrium. From there it then went to the lungs through the Pulmonary vein. Within the lungs, the deoxygenated blood becomes oxygenated, which is then sent through left atrium

Ways Biology Plays a Role in Life

...Ways Biology Plays a Role in Everyday Life and Benefits Society A. Biology is used by doctors to treat diseases in humans and animals. Farmers use biology to understand their crops. Marine biologists use biology to protect and understand ocean life. Nutritionists use biology to understand the way bodies interact with food. Health inspectors use biology to set standards for food safety. B. Biology is a person's daily life. The food you eat was produced using biological processes. There are quadrillions of biochemical reactions going on in your body at any given moment. Your environment is affected by biological processes, many organisms and chemicals found in your environment affect you. C. Any drug you ever take to cure your headache or eliminate an infection was developed using biology (and chemistry & etc.). Making breads and cheeses depends on biological processed carried out by yeasts and molds. All the oxygen you breathe was generated by biological processes (specifically, photosynthesis). Virtually all the energy you use was created by biological processes. (Oil and coal are both ultimately derived from plant matter.) D. Biology connects to my life due to many factors; for one my school is almost completely surrounded by a swamp in which, occasionally, I see its various organisms and plant species.  Another way biology connects to my everyday life is the bread I eat, in which before it’s made into a sandwich (or even into bread for that matter)...

...HOW CAN I USE SCIENCE FOR FUTURE DEVELOPMENT OF INDIA ------------------------------------------------------------------------------------------------------------------------------------------ Development at any phase is always linked with technology and technology happens when there is advancement in science. Hence science, technology and development are all proportional to each other. Development is required in every individual to every nation in all aspects and for development to happen, science and technology go hand in hand. Basically science is known as the study of knowledge, which is made into a system and depends on analyzing and understanding facts. Technology is basically the application of this scientific knowledge. For any successful economy, particularly in today’s quest for knowledge based economies, science, technology and engineering are the basic requisites. If nations do not implement science and technology, then the chances of getting them developed becomes minimal and thus could be even rated as an undeveloped nation. Science and Technology is associated in all means with modernity and it is an essential tool for rapid development. Modernization in every aspect of life is the greatest example of the implementation of science and technology in every nation. With the introduction of modern gadgets in every walk of life, life has become simple and this is possible only because of implementing science and technology together.

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...

Life Stages

...stages of the human life cycle. In today’s modern world biology alone no longer controls the life course and huge variety is now found e.g. getting married, having children, where you will live. Life expectancy is an estimate of the number of years a person can expect to live, on average. Developmental norms (developmental milestones) is the average set of expectations for a child’s development, however it is important to remember that each child is unique. Delayed development is when the norms aren’t reached in the certain time they are expected to. Potential causes and effects * Brain damage * Poor social interaction with carers * Disease * Visual disability * Hearing disability * Poor nutrition Arrested development is when development has stopped prematurely. Holistic development is the whole development and growth. All the P.I.E.S are likely to interact with each other.

Inception to Demis

...Jacob Orvidas Ms. Stegenga 9/10/2012 Definition of Life Life: Inception to Demise The question “when does life begin?” has been a topic that has received a large amount of publicity in fields ranging from biology to politics. It almost always leads to an opinion-based argument that does not have a correct answer. But what is often overlooked is the view from the opposite spectrum, “when does life end?”. These two questions go hand in hand but the focus is almost always on Inception. In my mind what truly matters is whether or not the legal definition of life and death coincide with the biological definition, and what your personal opinion on the matter is. First, I would like to address the differences between being biologically dead and legally dead. The Uniform Determination of Death Act (UDDA) has been adopted by all 50 states to legally determine life and death. The UDDA recognizes whole-brain death, or death due to ceased function of the lungs or heart. Whole-brain death is constituted as “irreversible cessation of all functions of the entire brain” (USlegal.com). A person can be legally dead even if his/her cardiopulmonary system continues to function. This is why patients in a coma will be kept alive for long periods of time. The longest being Elaine Esposito, who lived in coma for 37 years and finally died. Which raises the question of whether or not being in a coma should be considered alive? Especially when it is taken into account that “last year, Medicare...

...the electric kettle to boil water for tea, while a jar of milk heats in the microwave. I turn on the gas oven to warm up the brioche I baked yesterday. It smells delicious and it looks even better, golden and spongy due to the work of yeast. And, while the rest of the family comes down to have breakfast, I turn on the radio to listen to the latest news around the Globe. I have been awaken for just some twenty minutes and science is all around me: the movement of planets, the electricity, the water treatment, the transformation and piping of the gas we use to cook and heat out homes, the chemistry behind new fabrics, the radio waves or the power of the small fungi we use for our pastries. Whatever I do, whatever I see, science is at the heart of everything. And the day has just begun.

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...

All Things Bright and Beautiful

...Have you ever heard the poem entitled “All things bright and beautiful” during your grade school? Me, I have memorized this on our English class for recitations’ sake without learning it by heart as advised by our teacher. It’s only during these past days that I appreciated it. It was during my Ecology class, when I was attentively listening to the discussion regarding the cycles taking place in an ecosystem. We talked about the energy flow and material flow that includes the biogeochemical cycles. These cycles connect the biological, geological and chemical aspects of the biosphere. We arrived at the realization that all things on earth are functioning so that our instructor end up our lesson saying “See, how God created things beautifully?” I’ve got a smile drawn in my face. Nevertheless, most people nowadays not actually appreciate such fellow creations around them. They are being susceptible to pin them as “useless” and even question their existence in our planet. There is this group in the social network that ranked the most useless living organism in the world. Some living organisms that are not beneficial to them like the Pandas, bugs, cockroaches, mice, flies, makahiya plants and the like. They aren’t aware of the role of each life form in the setting. They say pandas are lazy thus useless, for it does only eating 9 hours a day, sleeping and getting overweight. I’ll say pandas are to distribute seeds of bamboos throughout an area. They depend on bamboos, just as...

...through life. John was the youngest son of farmer Kenneth Doyle and his wife Mary Doyle. Kenneth, a hard working man, raised his four children in a very disciplined way. It was from here that John learned much of his punctuality. John, after leaving home at age 18, decided to move to a city. He went to Chicago and became a reporter for several years. He enjoyed his job, but yearned to get a college education. He enrolled at the University of Chicago. From there he quickly realized that he loved Health Care and Biology. Soon he made his decision that he was going to study to become a biologist. Years after he graduated, I, his wife Darlene, asked why he felt so akin to his biological work. He always responded "that this is something I enjoy doing and when I feel I am making progress, I realize how beneficial my work is." As you can see, John was a very hard working man. He ended up finishing his work and retiring at the age of 58. After a brief heart attack, John realized he could no longer work as hard a he had done in his younger years. On May 2, 1999 John passed away. Occupation: John at the age of 20 found his true calling in life. John wanted to be a biologist. His whole life he felt a strong connection with different attributes of animal nature. John always believed that we were bound together in the animal kingdom in one way or another. John realized with the discovery of the DNA molecule that he was right in his assumptions. Accomplishments: ...

One of the most fascinating organisms on earth can be found in your very own home. If you own an aquarium or have ever visited an aquarium, lake or ocean, the chances are you have observed a fish. Fish have a very unique anatomy and physiology so that they can thrive in underwater environments. Like humans fish have a closed circulatory systems, but the way that blood flows throughout the body is different and perhaps even simpler. In a fish, blood flows from the heart, to the gills, to the body and back. Gills are analogous to the lungs of humans but the way they take in oxygen is very different. Water flows over the gills and the gills absorb dissolved oxygen. Fish sense their environment in a number of different ways that are unlike humans. Some fish can smell their environment through their skin in addition to using their nares. Additionally fish can sense electric fields and their environment using a structure called a lateral line. These structures are unique to fish and allow them to perceive their environment and live successfully. Have you ever wondered how fish swim? Fish maintain their buoyancy through an anatomical structure called a swim bladder. Essentially this is like a built into...
