The humor present is this essay is mostly at the expense of men. They are portrayed as klutzy kitchen…

Water is the best aid in attaining large, beautiful, and firm breasts. This was a major secret of the ancient Greek beauty queens. And some historical records reveal their simple recipe: dipping the breasts in cold water for five minutes every night. Nowadays, it is scientifically proven that cold water and repeated hot-icy showers are a must for the breast beauty and health. However, professionals claim that a hot water bath also has good effects on the size of breasts. Due to the excessive…

solution (2 ml) added and stir for 10-15 min. The Solid filtered off and washed with solvent mixture. The combined filtrate concentrated at reduced pressure to remove THF , then the aqueous residue extracted with 2 X 40 ml ethyl acetate. The combined ethyl acetate layers washed with water and dried over MgSO4. To this ethyl acetate layer, 2ml of glacial acetic acid added and stirred the reaction mixture at room temperature to afford acetate salt of 1-(2-amino-1-(4-methoxyphenyl)ethyl)…

the anode (positive electrode) when an electric field is applied across the gel. Agarose Gel Preparation Reagents: 1 X TAE Buffer, Agarose 0.8 % Gel, (Ethidium bromide solution (10 mg/ml in water).  TAE buffer is a buffer solution containing a mixture of Tris base, acetic acid and EDTA) 1 X TAE buffer is prepared by diluting stock solution of TAE buffer which is at a concentration of 50X , by diluting 49 ml of triple distilled water and 1 ml of 50 X TAE buffer. Gel Preparation To prepare 50…

the mixture is then heated to a temperature of about fifty degrees Celsius, and 100g of fine powders of antimony sulfide are added in small amounts periodically to the heated mixture. After all of the crystals of antimony sulfide have been added to the mixture and evolution of hydrogen sulfide has subsided, the temperatures are adjusted to higher levels gradually until the resultant…

Outline of Experiment Title: The effect of phenoxyethanol on plant growth Question: Is phenoxyethanol, a preservative for several cosmetic products, improve the rate of plant growth on lima beans? Hypothesis: If the phenoxyethanol is mixed with the soil that is given to a lima bean plant, the plant will continue to grow. Based on following research I believe the lima bean plant will grow at the same rate as the control group because according to the classification scale of Hodge and Sterner,…

an English geneticist named J.B.S. Haldane came up with this theory in 1920. to test this theory they collected and mixed elements thought to be on earth at the time and sparked the mixture with electricity, The experiment resulted in the creation of amino acids. The reasoning was that life formed because of a mixture of chemicals and the atmosphere. Iron sulfur World: theory that proposes that life began on the surface of iron sulfide minerals.…

majority of these residents were used to the smoke that had emerged or arose due to a local zinc smelter. However, on this day there was an adjustment in temperature and a deficiency of wind that confined a deadly mixture of sulfur dioxide, carbon monoxide, and metal dust. This toxic mixture ends up remaining in the air for five days. Forlornly, due to this environmental disaster, 20 residents had lost their lives and 7,000 other residents agonized from conditions such as: nausea, vomiting,…

Observation, results, and calculations Observations During this experiment, it was observed that sucrose shows a soluble component which physical appearances results to be more crystal in nature and bonded together during the first separation. The separation of dichloromethane and sodium hydroxide reveal two layers of different density liquids solution whereby one is denser in nature than the other solution. The dense solution is referred to as the sodium hydroxide while the bottom layer which…

The role of sodium citrate is to reduce silver nitrate to silver (1). The role of D-glucose was to reduce silver nitrate into just silver, while soluble starch stabilizes the nanoparticles by surrounding them to prevent aggregation (1, 2, 3). The 1 M NaOH, 1 M HCl, and 1 M NaCl caused Batch A to aggregate. The nanoparticles aggregated with these reagents because these are all strong bases or strong acids, which dissociates completely and interacts with the oxidized citrate that separate the…
