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

Introduction Prior to OSI‚ networking was largely either government-sponsored or vendor-developed and proprietary standards such as SNA and DECnet. In the UK work on the Experimental Packet Switched system circa 1973‚ the need to define so called higher level protocols above the HDLC link level communications protocol and the content of an NCC publication ’Why Distributed Computing’ resulting from considerable research into future configurations for computer systems resulted in the UK presenting

Subsidiary assignment C: The election and values All the three presented enclosures are about the parliamentary election in 2011. Enclosure C1 is written by Rune Engelbrecht Larsen‚ enclosure C2 is written by Ida Auken and Astrid Krag (SF) and enclosure C3 is written by Bo Lidegaard. What all the three enclosures has in common is‚ that they all have immigration policy in focus. According to the enclosures‚ it is therefore the immigration policy that determines the content of the value policy in

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 good news about the ozone layer is not always frequent. On International Ozone Day‚ the report came in that the ozone levels have decreased above Montreal and other residents of southern Canada. The ozone layer shields the earth from most of the harmful radiation and light coming from the sun. The ozone reflects

Visual‚ Auditory and Kinesthetic (VAK) learning style model A common and widely-used model of learning style is Fleming’s (2001) Visual Auditory Kinesthetic (VAK) model. According to this model‚ most people possess a dominant or preferred learning style; however some people have a mixed and evenly balanced blend of the three styles: 1. Visual learners 2. Auditory learners 3. Kinaesthetic learners Visual learners tend to: • Learn through seeing • Think in pictures

There are many different layers within the Earth. The core is at center of the Earth. The Earth’s core takes up sixteen percent of Earth’s volume‚ containing thirty-three percent of its Mass ..Pressure rises steadily inside the earth because of the weight of overlying rock. Therefore ‚the Pressure at the outer boundary of the core reaches 1.37 million atmospheres‚ 3.7 million Atmospheres. The core is made mostly of iron and nickel and possibly smaller amounts of lighter elements including sulfur

The ozone layer is a deep layer in the stratosphere‚ encircling the Earth‚ that has large amounts of ozone in it. The layer shields the entire Earth from much of the harmful ultraviolet radiation that comes from the sun. Interestingly‚ it is also this ultraviolet radiation that forms the ozone in the first place. Ozone is a special form of oxygen‚ made up of three oxygen atoms rather than the usual two oxygen atoms. It usually forms when some type of radiation or electrical discharge separates

Ozone Layer It acts as a sun block and filters out the dangerous ultra-violet rays from the sun ("The Chemistry of the Ozone Layer"). The Earth ’s atmosphere is broken up into two layers that have to do with ozone ("Ozone Layer"). The troposphere is the lowest layer ("Ozone Layer"). It extends from Earth ’s surface up to about ten kilometers in altitude ("Ozone Layer"). All most all human activities happen in this layer ("Ozone Layer"). The next layer is the stratosphere ("Ozone Layer"). It

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’
