What is Acid Rain? First identified in 1872 in Sweden and studied in the U.S. beginning in the 1950s‚ acid rain is precipitation in the form of rain‚ snow‚ hail‚ dew‚ or fog that transports sulfur and nitrogen compounds from the high atmosphere to the ground. Sulfur dioxide (SO2) and nitrogen oxides (NO‚ NO2) are bi-products from burning fuels in electric utilities and from other industrial and natural sources. These chemicals react with water‚ oxygen‚ carbon dioxide‚ and sunlight in the atmosphere

2: Recrystallization and Melting Point Recrystallization (or Crystallization) is a technique used to purify solids. This procedure relies on the fact that solubility increases as temperature increases (you can dissolve more sugar in hot water than in cold water). As a hot‚ saturated solution cools‚ it becomes supersaturated and the solute precipitates (crystallizes) out. In a recrystallization procedure‚ an impure (crude) solid is dissolved in a hot solvent. As this solution is cooled‚ the pure

Homeostasis‚ the tendency towards a relatively stable equilibrium between interdependent elements‚ especially as maintained by physiological processes. Any living creature needs to maintain a constant internal environment in order for their cells to work at optimal levels in order for them to survive and reproduce. Thermoregulation is a type of homeostasis that keeps the internal body temperature at a consistent level despite external stimuli. When the thermoreceptors in the skin/hypothalamus notice

2013/2014 Assignment 1 (10 marks) Answer ALL the questions. 1. Discuss briefly fluid mosaic model for membrane structure. (6 marks) Answer: The lipids and most of the protein in the plasma membrane are free to bob about‚ sliding from one location in the membrane to another. Because lipids and proteins move about laterally within the membrane‚ the membrane is a fluid mosaic of lipids and proteins. The membrane fluid is since the composition of any location on the membrane can change. In the same

February 14th‚ 2014 ACID RAIN 1. Acid rain is rainfall created by pollution in the atmosphere. When the rainfall occurs‚ it almost always causes harm to the environment. 2. Acid rain is caused by the release of certain compounds into the air‚ including sulfur dioxide and nitrogen oxides. These compounds mix and react with chemicals such as oxygen and water and form acid rain. 3. Acid rain can harm the environment by acidifying lakes and streams‚ which greatly affects the water life. It also causes
