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’

Layers of the Atmosphere The envelope of gas surrounding the Earth changes from the ground up. Five distinct layers have been identified using... • thermal characteristics (temperature changes)‚ • chemical composition‚ • movement‚ and • density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics‚ chemical composition‚ movement‚ and density occur. Troposphere The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20

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

1. What model(s) of addiction do you prefer and why? Were there some ideas you agree or disagree with? I believe the causes of addiction vary considerably and are still yet to be fully understood. The model I preferred was the comprehensive model as it addresses the nature of Addictions as being generally caused by combination of physical‚ mental‚ environmental factors. As there are several factors that can influence the development of addiction the Comprehensive Model is the only one out of

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

The social model of gerontology refers to the “impact of social and sociocultural conditions on the process of aging and its social consequences‚” (Hooyman‚ 5.) So what exactly does this mean? Simply put‚ social gerontologists mostly study the ins and outs of the older generations (across many decades of aging) and how those lives are affected on a day to day basis by social constructs. When we use terms like “older generation‚” we do not mean it in a degrading way. As our textbook accurately points

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

Of Imagery and Detail Over the summer‚ my family took a trip up to Monterey. There‚ I noticed many tributes towards John Steinbeck. It ranged from statues‚ to restaurants named after him.
