  • Freezing Temperature Essay

    Varying environmental climates require organisms to develop defense mechanisms to survive. For conditions under freezing temperatures, each animal has a response. If an animal is unprepared for the extreme situation, the formation of ice leads to a destruction of tissues and most organisms are unable to tolerate even frostbite; which make animals adapt to stay warm and out of the cold. Biochemical studies have examined why amphibians can tolerate freezing temperatures. Many amphibians, though have learned to adapt specifically to these extreme cold environments. The adaptation is freeze tolerance, and many amphibians have undergone this adaptation to protect themselves from the harsh temperatures Freeze tolerance is the ability to regulate and endure the formation of ice in extracellular compartments while preserving the liquid state of the cytoplasm (Costanzo, Amaral, Rosendale, and Lee, 2013). Freeze tolerance has problems and challenges the amphibians have to overcome to be able to use it. The most difficult problem is the formation of ice and the challenges that…

  • Freezing Point Lab Report

    Freezing point is the temperature for a particular compound where the liquid freezes to form a solid (Chemistry Dictionary). If salt is added to water, it freezes at lower temperatures. If there are fewer water molecules, then freezing occurs at a slower rate (Salt and the Freezing Point of Water). Pure water freezes at 0º Celsius, but water that is combined with salt will freeze at a temperature less than 0º Celsius (Oleson, Andrew and Daly, Terik). A solvent is something in which other things…

  • To Build A Fire 'And Left For Dead'

    Many examples of naturalism are shown in the fictional short story, “To Build a Fire,” by Jack London, and in Beck Weathers’ non-fictional memoir, “Left for Dead.” In London’s fictional story, we learn of a man who went adventuring in the Yukon, looking for new trade routes. Unfortunately, the man was stopped short when the weather took a turn for the worst and got so freezing he could not even start a fire and eventually froze to death. In Beck’s story he gets caught up in a huge blizzard on…

  • Creative Writing: My First Vietnam War

    was made of paper. Red had stained the countryside, along with the limbs from soldiers that had been blasted off by explosives. These sights made me sick, the queasy feeling I had learned to live with due to the lack of food often grew worse, making me double up in pain, the bully beef and biscuits they served were nothing compared to my mother's homemade stew and bread. Thinking about this made me miss home even more and I pushed the thought out of my mind. I reached my resting place for the…

  • Dehumanization In The Holocaust Essay

    In these camps “the death rates were so high, from malnutrition, typhus and exhaustion that the disposal of corpses became a serious problem.” (THE CAMPS) The treatment in transporting and caring for the victims is probably one of the main factors in the dehumanization of people during Holocaust. The victims were treated inferior simply because of their nationality. The Nazi’s made it a point to degrade these people in every way possible by taking away their rights and free will.…

  • Blanching Research Paper

    Freezing is an essential preservation method in the food industry. When fresh fruits and vegetables are harvested the enzymes in them begin to change the fruit. They can lose color, nutrients, and their desired taste if not preserved. Along with freezing there are other strategies used to inactivate these enzymes. Vegetables are blanched before freezing and fruit can be dipped in a sugar syrup before freezing to keep them at their best. One of the main problems faced with freezing is a change in…

  • Experiment Freezing Point Experiment

    purpose of this experiment was to learn techniques to determine the freezing point of a pure benzophenone, a solvent. Furthermore, methods for determining the freezing point depression in relation to the solute, cyclohexanone, concentration were employed in addition to learning what molality is and how it related to the colligative properties being studied. These objectives were achieved by melting both pure benzophenone and benzophenone/cyclohexanone solutions (two solutions with different…

  • Does Sugar Affect The Freezing Of Water

    The Freezing point of water is 32° fahrenheit, But does anything affect the freezing point of water? The effect of salt and sugar lowering water’s freezing point is called Freezing Point Depression(FPD). When water freezes, its molecules slow down and “stick” together, and eventually slow down so much they stay in place and become a solid. However when salt or sugar is added, it “interferes with the formation of the crystalline bonds between water molecules that give ice its solidity”, Written…
