The cuticle plays an important role in the health of your nails. They provide a protective cover for the tissue that grows new cells that build the nails. As you know, your nails are constantly growing -- that's why you have to keep clipping them.he cuticle is the piece of skin that overlaps the hard nail and touches the lunula. You may be wondering what they do, or why you need them. If you get frequent manicures, they may be smooth and even, pushed back as far as they'll go.

An emission line spectrum can only be produced by a hot, tenuous (low-density) gas. Importantly, the wavelengths of the emission lines depend on the type of gas; e.g., Hydrogen gas produces different emission lines than Helium. Absorption lines can be best thought of as the opposite of emission lines. While an emission line adds light of a particular wavelength, an absorption line subtracts light of a particular wavelength. Again opposite of emission lines, absorption lines are produced by a cool gas. Naturally there must be some light to subtract, so absorption lines can only be seen when superimposed onto a continuum spectrum. Thus, for absorption lines to be seen, cool gas must lie between the viewer and a hot source (case âcâ).
