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.
Often it is possible to identify snakes by their shed skins alone (you can do so too, here). I have had some pretty serious exercise of this skill this week. In the past three days, I have found three fairly fresh snake sheds on islands in the Matanzas River.ost often, though, a shed is either torn apart by the snake as it sheds, or tears itself apart as a result of drying out (it is wet when the snake sheds it off, as a result of lymphatic fluid excreted by the snakeâs integument to aid in the shedding process).
