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 treatment for a snakebite is as variable as the bite itself. The most common and effective method is through antivenom (or antivenin), a serum made from the venom of the snake. Some antivenom is species-specific (monovalent) while some is made for use with multiple species in mind (polyvalent).ll snakes are strictly carnivorous, eating small animals including lizards, frogs, other snakes, small mammals, birds, eggs, fish, snails or insects. Because snakes cannot bite or tear their food to pieces, they must swallow prey whole. The body size of a snake has a major influence on its eating habits.
