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

A red velvet cake is a cake with a dark red‚ bright red or red-brown color. It is traditionally prepared as a layer cake topped with cream cheese or cooked roux icing. The reddish color is achieved by adding red food coloring. Common ingredients include buttermilk‚ butter‚ flour‚ cookie dough for the filling‚ cocoa‚ and beetroot or red food coloring. The amount of cocoa used varies in different recipes. Cream cheese frosting and buttercream frosting are commonly used. History: James Beard’s

How did they do that‚ well you will find out in a few short minutes.Today you will learn about the history of it‚ when different flavors were invented‚ and other different questions you may have about cake. Now let’s get straight into this article. The first cake was made in the early times of the Egyptian era. The Egyptians didn’t create cake‚ they were just the first ones to start

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

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

The OSI model has seven layers‚ with each having different types of security responsibilities. The seven layers are application‚ presentation‚ session‚ transport‚ network‚ datalink and physical with control being passed down from layer to layer starting with application. The biggest threat to these layers is through people‚ sometimes known as the 8th layer of the OSI model. Companies should take the time to educate their employees on the security threats that each individual brings to the company

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’
