I tried out putting chapstick on the side, erasing the side of the scantron, coloring in the bars next to the questions, etc. Scantrons have gotten so much more high tech and it's probably impossible to cheat in ways such as that.o it doesn't work! scantrons optically sense marks made on the scantron sheet and compare the marks to those on the answer key sheet. If anything, the extra marks on the scantron made by the chapstick will cause the grading machine to mark the answer as incorrect even if the answer was correct.
Snakes shed their skin to allow for further growth and to remove parasites that may have attached to their old skin. As a snake grows, its skin becomes stretched. Unlike human skin, a snake 's skin doesn't grow as the animal grows. Eventually, a snake 's skin reaches a point where further growth is not possible.
The fact that snakes shed their skin has suggested that they have a regenerative quality for treating chronic skin problems. As a result, snake skin and whole snake are used in the treatment of skin diseases. This application is similar to the use of sloughed cicada skin for treating skin ailments.Acne, carbuncles, itching skin, and psoriasis are examples of conditions that may respond to snake skin.mong the earliest recorded use of snakes in Chinese medicine was the application of sloughed snake skin, described in the Shen Nong Ben Cao Jing (ca. 100 A.D.) It was originally applied in the treatment of superficial diseases, including skin eruptions, eye infections or opacities, sore throat, and hemorrhoids.
