Light Bulb Grolier Multimedia
1,351 wordsOn October 22, 1879 Thomas Edison created the electric light or what we know of it today as the light bulb. To make a statement like this that Thomas Edison invented the light bulb is both a huge hyperbole and a huge understatement all at the same time. A more correct view is that he perfected a practical light bulb and that his real plan and accomplishment was the invention of an electrical system to produce and distribute electrical power. He did in fact invent a light bulb with the correct fi...

Sheet Of Cellulose Nitrate Sheet Of Cellulose Polymers
571 wordsPolymers have been around longer than we have. In fact, polymers are as old as life itself, as all life on earth is based on three types of polymers, namely DNA, RNA, and proteins. But this report is about some of the earliest synthetic polymers, that is, polymers made by humans, specifically, the cellulose derivatives. The very first synthetic polymer was of course leather, a modified natural polymer, an artificially crosslinked form of the proteins found in animal skins. Leather tanning was di...

Epithelial Cells Blood Flow
571 wordsNot all animals have lungs. Many animals live in environments where lungs would be efficient enough for survival. Gills are another type of respiratory system, which are very efficient at removing oxygen from water: there is only 1 / 20 the amount of oxygen present in water as in the same volume of air. Gills greatly increase the surface area for gas exchange and they occur in a variety of animal groups including arthropods (including some terrestrial crustaceans), annelids, fish, and amphibians...

Muscle Contractions Skeletal Muscle
875 wordsThe musculoskeletal system is made up of bones, joints, and muscles. This system gives the body form and support, and protects the body while allowing it to move. Basically, the muscles in this system perform three important body functions: the movement of body parts, maintenance of body parts, and production of body heat. These muscles all consist of a mass of protein fibers grouped together, and most are of mesoderm al origin. And almost all of the muscle fibers you will ever have or need were...

Dead Or Dying Based On Domination Fish
908 wordsOur categorizations of nature are based on domination. The world is divided ecologically into predator and prey, or bigger more advanced animals versus smaller simpler creatures. One category is superior which dominates the second category which is inferior. But this dualism based on dominance represented by the demand of a preferred human order upon nature is in fact contradictory. As an obvious example, carnivorous plants like the Venus flytrap consumes insects, and the bigger and more taxonom...
