Name the three layers of the skin and give a brief description of each layer. Epidermis- the outermost layer which depending on the body location has several layers. The stratum coreum which is thinnest outermost layer consisting of dead keratinized cells protect underlying cells and tissue from dehydration and stop entry of certain chemicals agents. The stratum basale

OZONE LAYER The Earth ’s ozone layer protects all life from the sun ’s harmful radiation‚ but human activities have damaged this shield. Less protection from ultraviolet light will‚ over time‚ lead to higher skin cancer and cataract rates and crop damage. The ozone layer is one layer of the stratosphere‚ the second layer of the Earth’s atmosphere. The stratosphere is the mass of protective gases clinging to our planet. Ozone is only a trace gas in the atmosphere only about 3 molecules for every

LANG/COMP 14 September 2012 Advancement of Aviation Technology of the Post-War period After the conclusion of World War two (WW2)‚ aviation took off and became one of the largest industries in the world. Over 300‚000 aircraft were produced. The post-war period was a time where the aviation industry became a multi-billion dollar industry. At the end of WW2 the U.S. government founded the Army Air Corps which was the United States Air Force. Commercial aviation also advanced significantly‚ allowing people

Skin Layers 1. Epidermis The epidermis is the outer most layer of skin. It is built up of 5 layers (from the outside in) - stratum corneum is made of dead flat skin cells - stratum licidum - stratum granulosum - stratum spinosum - stratum basale Where cells divide and push previously formed cells into the upper layers. As the cells travel into the higher layers‚ they flatten and die‚ eventually. Specialized Epidermal Cells - melanocyte - produces pigment (melanin) - Langerhans’

Aviation Aviation Aviation is a field of study for science‚ math‚ and engineering‚ a career path‚ and a source of obsession for many people. It shapes the world people live in today‚ often without them even knowing‚ or rather thinking about it. Winston Churchill once said “Air power may either end war‚ or end civilization” (“Air Power”). This quote represents aeronautics’ importance in the aspect of military endeavor‚ which is a major part of the world. Aviation is

and various trace gases make up the remainder. Scientists divided the atmosphere into four layers according to temperature: troposphere‚ stratosphere‚ mesosphere‚ and thermosphere. The temperature drops as we go up through the troposphere‚ but it rises as we move through the next layer‚ the stratosphere. The farther away from earth‚ the thinner the atmosphere gets. 1.TROPOSPHERE This is the layer of the atmosphere closest to the Earth’s surface‚ extending up to about 10-15 km above the Earth’s

The ozone layer is a layer in Earth’s atmosphere which absorbs most of the Sun’s UV radiation. It contains relatively high concentrations of ozone (O3)‚ although it is still very small with regard to ordinary oxygen‚ and is less than ten parts per million‚ the average ozone concentration in Earth’s atmosphere being only about 0.6 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere from approximately 20 to 30 kilometres (12 to 19 mi) above Earth‚ though the
