Problem: Article: The most beneficial undergraduate degree is one in pre-dentistry or a science. Degrees in science-related fields help you meet any prerequisites you will have when entering dental school. While in school, you should focus on getting good grades, learning as much as you can, and developing good study habits.  All US dental schools have undergraduate course requirements, which will be published on their websites. For example, most require that you take prerequisite courses in many sciences, including biology, chemistry, physics, anatomy, biochemistry, and physiology. You should also consider taking art and business classes. When you are applying for dental school, you will need to submit letters of recommendation along with your application. You should choose people who know your work ethic and characteristics, so they can provide strong and supportive letters for you. You can get letters from professors and any dentists you have shadowed or worked with during your undergraduate studies. Most applicants apply to more than one dental school. You should only apply to dental schools that are accredited by the ADA's Commission on Dental Accreditation or a similar accreditation organization for your country. Your undergraduate grades, score on the DAT, recommendations, extracurriculars, and interviews are considered in the admission process. When you go to dental school, you will receive a doctorate degree. A standard program is four years, which includes coursework and clinicals. You can get a Doctor of Dental Surgery (DDS) or Doctor of Medical Dentistry (DMD). These are the same degree. The only difference is the name. The dental school you go to will give out one or the other. You can also become a specialist, which will take a few years longer. The most important thing to make sure that you do is choose a program accredited by a dental organization, like the Commission on Dental Accreditation. After you finish dental school, you may decide that you want to do something more specialized than general dentistry. If this is your wish, you will need to become a specialist. Becoming a specialist requires acceptance into a residency or postgraduate program. Then, you will continue with postgraduate education for two to six years, depending on the specialty.   The competition for dental specialty programs is rigorous and only the very top candidates will earn a position. You will need to need to be at the top of your class in dental school and be involved in research or other extracurricular activities. There are nine recognized dental specialties: Dental Public Health, Endodontics, Oral and Maxillofacial Pathology, Radiology, or Surgery, Orthodontics and Dentofacial Orthopedics, Pediatric Dentistry, Periodontics, and Prosthodontics.
Summary: Get a bachelor's degree in a science-related field. Gather letters of recommendation. Apply for admission to a dental school. Complete coursework at a dental school. Take the required steps if you want to become a specialist.

INPUT ARTICLE: Article: Some forms of denaturation are permanent, while others can be undone. Cooking an egg or meat, for example, cannot be undone, but a protein that has been exposed to a high pH may regain shape when put in a more neutral environment. Whether or not the protein can refold will depend on its DNA. The DNA will hold the information needed for the protein to return to its native state. Return the environment around the protein to stasis and remove the denaturing element. Remove the acid or base, for example, or bring the protein back to a more reasonable temperature. Many laboratory supplies companies sell renaturation kits that allow you to screen for the best parameters to encourage renaturation. Such kits can be especially helpful if you are looking at proteins in a laboratory or experimental setting.

SUMMARY: Determine if a protein can refold. Remove the denaturing factor. Use a renaturation kit.

In one sentence, describe what the following article is about: Pink comes in many different shades, ranging from very pale to very dark. Each shade has its own benefits and will do different things for your overall look. For example:  Try a light shade if you want something that is easy to work with and maintain. Examples include: baby, cotton candy, pale, and pastel. Try a bright, neon-shade if you want a longer-lasting dye job. Examples include: atomic, carnation, cupcake, flamingo, magenta, and shocking. Stick with a deep shade if you have dark hair and can't bleach it light enough. Examples include: bordeaux, eggplant, violet gem, and virgin rose. In most cases, you should match your hair's tone to your skin's undertone. For example, if your skin has warm (yellow) undertones, choose a warm shade of pink that has orange or yellow tints to it. If your skin has cool (pink) undertones, stick with a cool shade of pink with hints of violet or blue. If you can't decide on a color, go to a wig shop and try on wigs in various shades. In most cases, you will need to bleach your hair. Keep in mind, however, that you can only bleach your hair so much. In these cases, you may have to settle for a darker shade of pink. For example, if you have dark brown or black hair, you may not be able to bleach it light enough in order to get a pastel pink shade. You may have to settle for a darker shade of pink instead. If you work in a professional environment with a strict dress code, that bright shade of pink may not be the best choice and may earn you a citation--the same goes for schools. If you work in an environment that allows for creativity (i.e. an art studio or an art school), then you might look right at home with your hot pink locks.  If your school or job has a strict dress code, consider a more natural shade of pink, such as rose gold. Ask your principal/employer if the color your want will be acceptable.
Summary: Decide how light or dark you want your hair to be. Choose a shade that flatters your skin's undertones. Be willing to compromise and choose a darker shade if you have dark hair. Select a shade that complies with your school or work dress code.

In one sentence, describe what the following article is about: In Safari, add-ons are referred to as "plug-ins". Click Help → Installed Plug-ins. This will open a new page that lists all of your installed plug-ins. You will be shown the file name for the plug-in (for example the QuickTime file is called "QuickTime Plugin.plugin"). You won't be able to uninstall the plug-in from within Safari, so make note of the file name. OS X has hidden the Library folder, which is where the add-on files are stored. You will need to unhide the Library folder to find the plug-in file.  Open your Home folder in Finder. Click View → Show View Options. Check the "Show Library Folder" box. Refer to the file that you noted in Step 2. Navigate to the folders that contain the plug-in files. The plug-in files may be located at Library/Internet Plug-Ins/ or ~/Library/Internet Plug-ins/. Click and drag the plug-in file to the Trash. Restart Safari for your changes to take effect.
Summary:
Open your list of installed plug-ins. Find the plug-in you want to remove. Enable your Library folder. Find the plug-in file that you want to remove. Delete the file.
