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.

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

It disturbs the natural balance. Driving away any living organisms in area‚ prevents land farming and it may wipe out a whole shoreline community. It is danger to the lives and property of residents near to the black sand mining operation‚ massive residential displacement‚ saltwater flooding‚ landslides‚ weakening

Salts Agar (MSA). This media contains salts that most organisms can’t tolerate due to their osmolity ranges. Microbes that normally exist under these conditions are able to grow. MSA is usually used for Staphylococcal species. Differential media provides chemical compounds that bacteria metabolize differently. The difference is observed by a colony or media color change. This media is often used to differentiate between groups of organisms with the same morphology and biochemical resemblances.
