Bacteria is a organism that is present in most habitats‚ as well as human bodies and other living organisms such as plants and animals. Bacteria multiplies by its self to progress and spread. Unlike other infections such as viruses‚ fungi or parasites bacteria is not always harmful in fact in many cases bacteria can be useful to the living organisms‚habitats or plants that it infects. Viruses are a small infectious agent that can only multiply inside the cells of living organisms although unlike

the idea that different organisms were related by descent‚ he devised a system that placed these organisms in a hierarchy. Through classification systems‚ scientist have found it easier to find answers to important questions. This way things are broken down more and easier to learn. Classification is the systematic grouping of organisms into catagories on the basis of evolutionary or structural relationships between them. The benefit of classifying organism is it makes the study

Water and me Water is a colourless‚ transparent and odourless liquid which forms the seas‚ lakes‚ rivers‚ and rain and is the basis of the fluids of living organisms. It is a chemical compound whose formula is H2O. It covers 71% of the earth’s surface and is necessary for every known organism to live. 97% of the total water found on the earth lies in the oceans. The rest of water is in the form of glaciers and ice caps (2.1%)‚ ground water (0.6%)‚ inland water (0.2%) and water vapours (0.001%).

Two important systems for classifying living organisms exists‚ the Linnaean system and the Cladistic system. Today’s older adults most likely learned of the Linnaean taxonomy system while in elementary and high school. The Linnaean taxonomy system‚ named after Swedish botanist Carl Linnaeus‚ is a rank-based system of classification used to categorize living things. Started in 1735‚ the Linnaean system categorized organisms into seven major ranked categories. These specific levels are‚ Start with

Physiology is the scientific discipline that deals with the processes or functions of living things. It focuses on how organisms carry out the chemical or physical functions that exist in a living system. 3. What does Homeostasis mean? Homeostasis is the tendency of an organism or a cell to regulate its internal conditions‚ usually

Biotechnology? Biotechnology can broadly be defined as the art of understanding and manipulating living organisms’ genes (code of life) and their products for the production of food‚ medicine‚ drink‚ or for other benefits or useful purposes to mankind and other organisms. Basically‚ it is a field of applied biology that involves the using of living organisms to create useful products for mankind and other organisms. BIOLOGY + TECHNOLOGY = BIOTECHNOLOGY Biotechnology can be used to solve many biological

Applied Ethics “Is it morally impermissible to use animals medically for human sake?” To begin with‚ we have to point out that under which situation is permissible to use animals for human sake. We believe we can only use animals when it exerts constructive and affirmative influence to human beings which means it might save lives and enhance the quality of living on a general basis and most importantly‚ when there is no existing alternative. Using animals medically for human sake is morally
