Bioindicator
Lichen (disambiguation)
Bioindicator’s are different types of living organisms that responds to different types of effect in the human environment. Lichens are a special type of Bioindicator that are used for air pollution. One main type of pollution is the sulfur-oxide pollution, which they get their personal needs from the atmosphere rather than from the soil in the ground. The lichens also react to the air pollution all- year round rather than a few months at a time. Lichens are also inexpensive to use for evaluating the air pollution. Lichens can also be used for some other things that different organisms can’t be used for. Lichens are closely associated with two very different organisms’ called alga and fungus. They all live in a symbiotic association. Lichens have special abilities that help them survive during extreme temperatures and extreme sources of moisture. Lichens have 3 different types of growth form: crusty which the edges are flat and hard to remove, leafy which the top and the bottom layers are different, then lastly you have the shrubby kind which is kind of similar to the Spanish moss when it’s hanging downwards. Lichens are widely use as environmental indicators and Bioindicator. Just say that the air is badly polluted with the sulfur dioxide then there possibly wouldn’t be any lichens being presented in the atmosphere. If the air is clean then the lichens would become more abundant. Some lichen species can handle some high levels of pollution and some are mostly found on pavement, walls and tree bark in urban areas. Lichens can be sensitive in certain areas; the most sensitive lichen is shrubby and leafy. Some lichens absorb the sulfur dioxide dissolved in water. These lichen species have very l...

...ure. Air pollution an acid deposition has led to problem for lichens on barks, because the tree has become acidic. Lichens and acid doesn’t mix at all, all of the acidity from the rainfall mixed with the sulfur oxide is not good for the lichens, the lichens end up dying from the particles mixed in with the rain. Lichen is a type of symbiotic organism which means it interacts between two different organisms living in close physical association; typically they help each other out. In other words they can share a mutual relationship between one another. Lichens are a special type of specie in its own way. They can also help measure toxins in radioactive metals because they bind these substances in there fungal threads where they concentrate with it over long periods of time. Basically lichens could be used for just about anything that people could use them for.
There are many dangers facing the Pine Barrens today. The most dangerous is the effect industrialization has on it. Many industries contribute to the mass pollution of water, land, and air. This greatly impacts the ecosystem of the Pinelands and the animals that live in it. Industrialization also leads to the building of more houses that are detrimental to the Pinelands because the Pinelands are being destroyed little by little every day. This ecosystem is too precious to waste, it needs to be preserved. Pollution has caused over forty species of birds to become endangered. Acid rain also causes the extinction of many species. Acid rain is the term used to describe the chemicals that are deposited through the rain. These chemicals travel through the soil and affect many plants and animals. Acid rain is a world-wide problem that concerns all ecosystems; acid rain needs to controlled by limiting the amount of pollution let out into the air. Another major issue affecting the Pine Barrens is forest fires. There are as many as four hundred forest fires per year.
This paper focuses on the benefits of stem cell research in the medical and nursing field. New technology is always being created to help us understand the way the human body works, as well as ways to help us improve diseased states in the body. Our bodies have the ability to proliferate or regrow cells when damage is done to the cells. Take for example the skin, when an abrasion or puncture to the skin causes loss of our skin cells, the body has its own way of causing those cells to regrow. The liver, bone marrow, heart, brain, and muscle all have cells that are capable of differentiating into cells of that same type. These are called stem cells, and are a new medical tool that is helping regrow vital organs in our body to help us survive. Stem cells can come from adult cells, or the blastocyst of the embryo. The cells that come from these are undifferentiated, and can be specialized into certain cell types, making them available for many damaged tissues in the body. While using stem cells in the body is a main use, they are also being used to help doctors understand how disease processes start. By culturing these cells in the lab and watching them develop into muscles, nerve cells, or other tissues, researchers are able to see how diseases affect these cells and possibly discover ways to correct these diseases. While researchers have come very far in using stem cells, there are still many controversies to overcome when using these cells.
We live in a world where being medicated has become a societal norm. Modern health care practices have set the stage for the proliferation of direct-to-consumer advertising (DTCA) of prescription drugs by pharmaceutical manufacturers. Some of these practices include the emergence of managed care organizations (MCOs), the legalization of DTCA of prescription drugs, the emergence of the Internet as an alternative promotional channel, the increased desire by patients to become more involved in their own health care decisions, the disillusionment with traditional medicine, and the rise of ‘alternative’ medicine, to name a few. There is an ongoing debate as to the ultimate harm or benefit of this relatively recent practice of pharmaceutical manufacturers to direct their promotional efforts away from the physician and towards the consumer.
Pollution is a massive problem, due to burning excessive amounts of fossil fuels and produces global warming. The rising in temperature of earth has resulted huge melting of polar ice caps, flooding of low-lying areas, and also rise in sea levels. If these conditions conquer the surface of earth it will face radical changes. Hence, the ozone holes are also being created trough this process, that creates a harmful UV rays that enters the earth surface. Apparently it affect human life trough causing diseases like cancer. Melanin that present in the skin reacts trough these high wave radiations. Skin cancer is one of the major forms of disease that known to be caused due to these reactions of the pigment present in the skin and infra-red rays. Besides that, when burnt sulphur, dioxide gas will also be produced. This factor forms acid rain. Acid rain could leads to destructions of most of monuments that were made up of brickwork or marbles. Even a lot of crops are affected due to the acidification of loams.
“Modern man does not experience himself as a part of nature but as an outside force destined to dominate and conquer it. He even talks of a battle with nature, forgetting that if he won the battle he would find himself on the losing side” (E.F. Schumacher, 1974).
Air pollution is known to affect human and animal life. Plants are also affected indirectly as air pollution is known to cause acid rain, an even deeper detriment to plant life than most. Lung related diseases are among the most important features that the world have come
I can never forget the time I wrapped slices of raw onions onto my grandpa's foot. I looked up at his strained face, and very calmly he said to me, "It burns, can you please take it off?" My dad, next to me, told me to ignore his requests. He studied Chinese medicine, and this was an Eastern remedy to lower blood pressure. My grandpa had recently had a spike in blood pressure, and it was terrifying to realize that I could have easily lost him to a heart attack or stroke.
The term bioethics refers to the moral principles used when one is making a decision while in the healthcare field. It is the moral compass that humans use to decide what is the right thing to do versus the wrong thing to do when faced with an ethical dilemma. These decisions may be based on principles, reasoning, personal beliefs, emotions, natural science, or other influential factors.
The Human Genome Initiative is a worldwide research effort that has the goal of analyzing the sequence of human DNA and determining the location of all human genes. Begun in 1990, the U.S. Human Genome project was originally planned to last 15 years but now is projected to be complete in 13 years. This project was started to find the 80,000 - 100,000 human genes and to determine the sequence of the 3 - billion chemical bases that make up human DNA. The information generated by the human genome project is expected to be the source book for biomedical fields, including those such as developmental biology and neurobiology, where scientists are just beginning to understand the underlying molecular mechanisms. The human genome project is expected to immensely benefit medical science. It will help us to understand and eventually treat many of the more than 4000 genetic diseases that afflict mankind, as well as the many multifunctional diseases in which genetic predisposition plays an important role. New technologies emanating from the genome project will also find application in other fields such as agriculture and the environmental sciences.
The term ‘Natural Selection’ was first coined by Charles Darwin in his book, ‘On the Origin of Species’ which was published in 1859. ‘Natural Selection’ is the process by which organisms having traits that empower them to modify to certain environmental pressures, climatic changes, competition for food, and rivalry for mates, will help them to survive and reproduce more than others of their kind and in this way ensures the prevalence of these advantageous traits in the subsequent generations.
Natural selection is the gradual process by which biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. It is a key mechanism of evolution.
Genetic modification is a process of altering the genetic material of an organism by the use of a method that does not occur in nature. Genetic modification involves isolating, removing and manipulating DNA, and then reinserting the DNA into the same organism or into the genetic material of another organism. Which then leads to the creation of a genetically modified organism (GMO). GMOs can be plants, animals or (most commonly) micro-organisms. The use of GMOs in agriculture is rapidly increasing, since it produces a greater yield in crops than the traditional way of farming. Even though the production of GMOs are increasing, that does not necessarily mean it is completely safe for us to consume, companies that produces genetically modified
As everyone knows, the history of human evolution originated from more than five million years ago (Pickrell, 2006). Human is the most intellective living being on the Earth, even in the developed universe. With the development of human being, the beginning of human started to be discovered. This essay will focus on the evolution history of human being. It will explain three most significant time slices of human evolution.
Pollution can have an impact on our health, not only affecting people with impaired respiratory systems such as asthmatics, but very healthy adults and children too. Plants can be a benefit for pollution in the air, trees, bushes and other greenery growing in the concrete-and-glass canyons of cities can reduce levels of two of the most worrisome air pollutants by eight times more than previously believed. The more trees we can plant the less pollution we get and more air than just having a huge land and having abandoned buildings taking up space. To solve water pollution is to conserve soil, the best way to combat soil erosion is to keep the banks of waterways well-covered with soil-retaining plants.
My passion for “original” medicine, also known as natural medicine, will elicit an advancement in the diversity of medicine. There needs to be a paradigm shift in the way the field of medicine is viewed, by both the public and the physician. When I become a physician, I will indubitably utilize the power of natural medicine to offer vitality and true health to my patients. I will be an advocate of diversity and I will be a pioneer of what is seemingly “abstract” medicine, which has technically been around longer than any class of medication; simply, Foxglove (Digitalis Lanata) came before Digox, and Poppy (Papaver Somniferum) before Vicodin-case closed. The reality is that Western medicine is diametrically opposed to the medicine practiced by the cultures of many of America’s inhabitants. It is
