Wilmut And Dr Unicellular Organisms
1,428 wordsThe biological definition of a clone is an organism that has the same genetic information as another organism or organisms ("Cloning", 1997). From this definition and from information about the science behind cloning, my current view on cloning is that it is ethical. This statement ignores information about how we can misuse cloning and what consequences occur when the procedure is unsuccessful. I currently do not think cloning should be used until it is perfected. I doubt however that we will a...

Rapid Expansion Blue Green
1,211 wordsUp until 1947, it was believed that the Cambrian Explosion marked the first true abundance of multicellular life. However, this was discovered to be untrue after Sir Douglas Mawson and R. C. Spring mistakenly came across numerous "fossil jellyfish" in the Ediacaran Hills while observing what was originally believed to be sandstones belonging to the lowest strata of the Cambrian. At first, these finding were dismissed as "fortuitous inorganic markings. " (AAS Biographical Memoirs. ) Several years...

Disease Causing Entire Body
448 wordster> The nature of DISEASE CAUSING ORGANISMS and the mechanisms employed by man to combat these organisms. What is disease? A disease is a disturbance in the normal structure or function of an organism, group of organisms or the entire body. Diseases affect different organisms in different ways, they may be temporary, they may be chronic, or they may be terminal. They may even be localized or widespread through an entire body. Many diseases have been eradicated, but, some have no cure....

Ecology The Study Of Plans Animals And Environment
1,134 wordsEcology is the scientific study of the interrelationships of plants, animals, and the environment. In recent years, the word has sometimes been misused as a synonym for environment. The principles of ecology are useful in many aspects of the related fields of conservation, wildlife management, forestry, agriculture, and pollution control. The word ecology (Greek, oikos, "house, " and logos, "study of") is generally believed to have been coined by Ernst HAECKEL, who used and defined it in 1869. T...

Ecology The Study Of Plans Animals And Environment
1,192 words... ugh the changes occur gradually. Eventually a point is reached at which the environmental and species changes are minimal and species diversity is high. This relatively stable community is called a CLIMAX COMMUNITY. ECOSYSTEMS Many ecologists study communities in the context of an ecosystem, which includes interactions involving mineral cycling, energy flow, and population control. The study of ecosystems facilitates a functional approach to ecology. One of the major aims of ecological resea...

The Biological Importance Of Water
1,055 wordsGenerally, the main biological importance of water is that life cannot exist without it. In fact on a percentage basis, the majority of any organism is comprised of water. Additionally, it is believed that life first originated in the bodies of water on the earth. The importance of water is seen in such third world countries as Kenya. Where the inhabitants are forced to drink water so dirty and contaminated that they know it might kill them. However they still drink it because its essential for ...

Type Of Cloning Cloning Of Humans
1,762 wordsCloning Cloning as a concept has been recently launched by scientists and adopted by contemporary popular language. In 1997 biologists together with genetic and medical specialists of Roslin University in Scotland managed to produce the cloned sheep Dolly and officially publicized its existence. [ 2 ] Since those times the idea of cloning became a subject of intense interest and permanent discussions all around the world. For the last decade it remains to be one of the most emotional and controv...

Million Years Ago 65 Million Years
3,666 wordsIntroduction To Evolution What is Evolution? Evolution is the process by which all living things have developed from primitive organisms through changes occurring over billions of years, a process that includes all animals and plants. Exactly how evolution occurs is still a matter of debate, but there are many different theories and that it occurs is a scientific fact. Biologists agree that all living things come through a long history of changes shaped by physical and chemical processes that ar...

Wilmut And Dr Unicellular Organisms
2,092 wordsThe biological definition of a clone is an organism that has the same genetic information as another organism or organisms. Thus, an elaboration on the history, techniques, ethics, and reasons for researching the technology of cloning is necessary. A clone is an organism derived asexually from a single individual by cuttings, bulbs, tubers, fission, or parthenogenesis reproduction. Parthenogenesis reproduction is the development of an organism from an unfertilized ovum, seed or spore. Hence, clo...

Crown Of Thorns Coral Reefs
3,746 wordsCoral reefs are among the most varied and productive communities on Earth. They are found in the warm, clear, shallow waters of tropical oceans worldwide. Reefs have functions from providing food and shelter to fish and invertebrates to protecting the shore from erosion. Unfortunately, as our understanding of corals and coral reefs increases, it becomes apparent that the effects of the human population on these communities may be increasing as well. Reef-building (or hermatypic) corals are of th...

Living Organisms Magnetic Field
910 wordsCould icy moons of giant planets, such as Europa and Callisto, provide possible habitable environments for living organisms? Until such task is actually accomplished, scientists and researchers all over our world will forever be trying to find life in other parts of both our galaxy, and the Universe. Such fascination with extraterrestrial life has been brought to somewhat of a peak with the recent findings on two of Jupiter's so-called Galilean Satellites: Europa and Callisto. The findings from ...

Petri Dishes Flowering Plants
3,855 wordsIs there an effect on Rhizobium bacteria by changing its pH? Steve Lincoln Period 3 12 / 7 / 98 Question What are the effects of varying pH levels on Rhizobium bacteria, and can a pH resistant Rhizobium culture be grown? Hypothesis Alterations of the balanced habitat such as the change of pH levels can drastically alter the life of bacteria and can directly affect chemical reactions of enzymes released by the bacteria. Using this information the change in pH will have an effect on the Rhizobium ...

Million Years Ago Mass Extinction
10,014 wordsEarth probably began Extinction Introduction Earth probably began about 4. 5 billion years ago. A history of this life on Earth is recorded in fossil remains and traces of past life. It is a record of evolution for both life and the planet. Life and the planet have co-evolved, with life causing changes to the planet which in turn drive changes in life. The Fossil Record A history of these changes is recorded in the layers or strata of rock laid down over the millions of years, and by changes in ...

Asexual Reproduction Molecular Biology
872 wordsAll living organisms are composed of cells. A cell is a small, membrane-bound compartment that contains all the chemicals and molecules that help support an organisms life. An understanding of the structure of cells is one of the first steps in comprehending the complex cellular interactions that direct and produce life.

Paleo Ecological Reconstruction Paleo Ecological Evidence Organisms
1,100 wordsOne of the principal objectives of geologists studying sedimentary rocks is the reconstruction of the environment in which the rocks were deposited. Correct reconstruction may result in the discovery of oilfields, deposits of salts, or base metals, and provide insight to our earths past. As evidence to ancient environments the geologist has the structures, textures, and composition of the grains that make up the sediments, and the fossils preserved in them. Organisms are far more sensitive to, a...

Darwin Theory Earth Surface
2,710 wordsEvolution, a process of change through time, is what links together the enormous diversity of the living world. A lot of evidence is present that indicates that the earth has had a very long history and that all living things arose in the course of that history from earlier, more simpler forms. In other words, all species have descended from other species and all living things share common ancestors in the past. Basically, organisms are what they are because of their history.
