Nouchee Lor Mrs. Kottke IB HL English 11 October 2012 Reflective Statement “He was of medium height. His shapely‚ slim figure and broad shoulders gave evidence of a strong constitution‚ capable of enduring all the hardships of a nomad life and changes of climates‚ and of resisting with success both the demoralizing effects of life in the Capital and tempests of the soul” (Lermontov pg. 50). A true man is a man who takes responsibility. He is a man who takes responsibility

The Physics of Rainbows As we are coming down to the final weeks of winter‚ the days are getting longer‚ and it is slowing starting to warm up. We are all looking forward to springtime‚ with its promises of flowers and rain. Along with this rain brings reminders of rainbows. As Donald Ahrens says in the Meteorology Today magazine‚ “rainbows are one of the most spectacular light shows observed on earth (About).” In fact‚ one of the best ways to view a rainbow at it’s utmost

internal temperature so that the body processes can take place efficiently. The process ensures an equilibrium system is attained for all the body processes. The body temperature of an average individual is 37˚ C. this temperature fluctuates depending on activities one does. A human being is in constant movement unless they are asleep. As such‚ the temperature may increase or decrease thereby varying from this average. Some of the factors that may lead to increase in the body temperature include digestion

Abstract This experiment was designed to answer the question does temperature affect the amount of osmosis? The hypothesis predicted was that the higher the temperature the more osmosis would occur‚ but too high the osmosis would halt due to enzyme and substrate overheating and losing shape. After research and class time it was concluded that osmosis is a passive transport and would not require energy or enzymes due to it going from high to low concentrations with the gradient

Lab #5: Dissolved Oxygen Lab Be sure to read and understand the below instructions BEFORE the lab! Experiment 1: Investigating the Effect of Temperature and Salinity on the Concentration of Dissolved Oxygen in Water Introduction: In an aquatic environment‚ oxygen must be in a solution in a free state (O2) before it is available for use by organisms (bio-available). Its concentration and distribution in the aquatic environment are directly dependent on chemical and physical factors and are

3. Recent technological developments have allowed greater use of the electromagnetic spectrum 1. describe electromagnetic waves in terms of their speed in space and their lack of requirement of a medium for propagation In space (a vacuum) electromagnetic waves travel at the speed of light‚ a constant equal to 3.00108ms1. Unlike sound waves‚ electromagnetic waves do not vibrate particles‚ therefore they do not need a medium (substance) to propagate (move). 2. identify the electromagnetic wavebands

atmospheric pressure is suspended from the ceiling of a large room. The steam temperature entering the pipe is 120 oC‚ and the air temperature is 20 oC. The overall heat transfer coefficient on the outer surface of the covered pipe is 10 W/m2.K. if the velocity of the steam is 10 m/s‚ at what point along the pipe will the steam begin condensing and what distance will be required for the steam to reach a mean temperature of 100 oC?
