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.
Oppositely to warm up their internal temperatures, snakes lie in the sun for long periods of the day, resting on large hot rocks so the conduction of the heat will increase body temperature and keep them warm during the day. Snakes are said to use behavioural adaptations to regulate their body heat. This explains why they choose to move into a cold or a hot location at different times depending on whether they need to be hotter or colder, the snake has no biological way of regulating temperature, therefore behavioural adjustments have to be made everyday.
