This weekend you are going camping with your closest friends and family. Thankfully, the layers of your skin will help protect you during this adventure. Discuss at least two ways each layer, the epidermis and dermis, may protect you on this excursion.

Epidermis - barrier or protective layer

dermis- thermoregulator or maintain the temperature.

Explanation:

The two main skin layers that are present on the surface of the skin are the epidermis and the dermis layer (below the epidermis). These two layers are helpful in protecting from the excursion.

The epidermis layer is a protecting layer in general that acts as a barrier to protect the inner body from infection and also acts as the waterproofing layer.

The dermis regulates body temperature in an individual if the outer environment is too hot or cold, by sweat in a hot environment as it regulates the sweat glands.

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]
