The skin consists of two layers and a closely associated layer. View this animation (http://openstaxcollege.org/l/layers) to learn more about layers of the skin. What are the basic functions of each of these layers?

To write:
The different layers composing the skin.
Introduction:
The skin is composed of the three main layers, namely the epidermis, the dermis, and the hypodermis. The epidermis is the outermost layer while the dermis is present just below the epidermis. The hypodermis is the deepest layer of the skin.
Explanation of Solution
The epidermis, which is the outermost layer of the skin, functions as a waterproof barrier. It protects the tissue lying beneath it from infection, chemicals, dehydration and any kind of mechanical stress.
The dermis is present just beneath the epidermis. It is composed of tough connective tissue and include different types of the glands and the cells. The blood vessels in this layer provide nourishment to the tissues.
The hypodermis layer is made up of the connective tissue and fat. It functions by attaching the dermis to the muscles and the bones. Moreover, this layer stores fat as an energy reserve.
The skin is made up of three layers, namely the epidermis, the dermis and the hypodermis. The epidermis act as the protective layer. The dermis contains the blood vessels, and the hypodermis contains the fat.

What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb. Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place. Because protein requirement is a range, please enter two numbers: lower and upper range values, respectively.

Current treatments are focused on highlyactive antiretroviral therapy (HAART). HAART usually consists of an orally delivered drug cocktail containingtwo different reverse transcriptase inhibitors and one other drug, such as a protease inhibitor. Question: Develop a pharmacokinetic model of HAART treatment. Consider all 3 drugs. Make sure to include adiagram that illustrates your thinking, state all assumptions, and define your variables. Whatparameters would you need to know to find the concentration of drug in the plasma?

Marine fish cells are hypotonic compared to their seawater environment; their cells lose water by osmosis and gain solutes. If you add heterotrophic respiration and autotrophic respiration together and then subtract that value from gross primary productivity, then you have a more refined estimate of ecosystem carbon storage than NEE.
