The Effect of Varying Molecular Weights on the Rate of Diffusion of Substances August 22‚2012 ABSTRACT The effect of molecular weight on the rate of diffusion was verified by the 2 tests: the glass tube setup and the water agar-gel setup. In the glass tube setup‚ two cotton balls were soaked in the solutions of hydrochloric acid (HCl) and ammonium hydroxide (NH4OH) and were simultaneously placed on both ends of the tubing.NH4OH had a lighter molecular weight of 35 g/mole which diffused

Sleep enables our brains and bodies to rest‚ equipping us to take on the next day. A normal sleep cycle consists of 5 stages‚ 1‚ 2‚ 3‚ 4‚ and REM. If sleep is disturbed it can cause problems with health and everyday life. Stage 1 is when sleep is light and one can be awakened easily. In this stage we begin to drift in and out of sleep‚ the eyes move slow and muscle activity slows. Stage 1 lasts about five minutes and is followed by stage 2. Stage 2 eye movement stops and brain waves become slower

they will stop breathing repeatedly as they try to sleep. In some cases‚ people with severe sleep apnea will stop breathing hundreds of times a night. Every time they stop breathing‚ they are denying their body and brain the oxygen that they need. What Is Sleep Apnea? There are two main types of sleep apnea‚ although it is possible to have a blend of both conditions. The main types of sleep apnea are: Central Sleep Apnea: This type of sleep apnea occurs when the brain forgets to tell the muscles

The gilded age was a time after the American Civil War and it sprung an economic power house. The development of factories which were built by the union to defeat the confederacy remained open and were not shut down they were remodeled and converted into peacetime purposes. Even though big industries existed before the war the most significant portion of economy which was agriculture was what represented American economy the most. Following the war the production of

ABSTRACT The effect of molecular weight on the rate of diffusion was measured using two tests namely: the glass tube test and the agar-water test. The set-up of the glass tube test used two cotton balls of the same size. One cotton ball is moistened with hydrochloric acid (HCl) and the other one is moistened with ammonium hydroxide (NH4OH). The two cotton balls were inserted in both ends of the glass tube. NH4OH which has a lighter molecular weight (35.0459 g/mole) diffused with a faster rate (dave=20

Transfer of Food Preference in Rats after Initial Taste Preference ---------- --------------- Abstract Rats are animals known to be neophobic‚ fearful of new experiences and tend to show behaviors of avoidance to eat novel foods. However‚ there are high chances that rats will eat novel foods if they have reasons to expect that the food is safe to consume and not harmful. The social transmission of food preference paradigm (STFP) was tested in 28 male rats that were about 5 months old
