I hoped for a bid card from Alpha Phi for many reasons‚ but one of the most prominent was the values the Fraternity stands for. Sisterhood‚ Scholarship‚ Service‚ Leadership‚ Loyalty‚ and Character Development are all values that are important to me. To begin‚ I exemplify sisterhood through many ways. It can be a bigger contribution‚ for example when I help my big push through her Nursing interviews and help her pick out her outfits‚ while quizzing her on the questions she may be asked. There are

Amino acids are the building blocks of proteins. Amino acids bind together to form polypeptide chains‚ and these polypeptides fold and coil together into specific conformations to form proteins. There are 20 different amino acids‚ each amino acid consisting of four distinct partners. The first is a carboxyl group. A carboxyl group has very weak acids that are able to donate hydrogen ions to biological reactions. The second partner is the amino acid group. Amino acid groups act as the base which‚

! Affect of pH on Porcine Pancreatic Alpha-Amylase Activity Introduction Proteins function in a variety of different ways‚ and one of their fundamental tasks is to act as enzymes. Enzymes are extremely important in controlling reaction speed (by initiating and regulating biological activity)‚ cell communication‚ and growth. One particularly significant enzyme is amylase‚ which catalyzes the hydrolysis of alpha glycosidic linkages of amylose‚ starch components‚ and other oligosaccharides (Qian

This paper will discuss Alpha Kappa Alpha Sorority‚ Incorporated‚ and how it started. The sorority was founded by nine educated black college women. By the names of Ethel Hedgeman-Lyle‚ Anna Easter Brown‚ Beulah Elizabeth Burke‚ Lillie‚ Burke‚ Marjorie Hill‚ Margaret Flagg (Holmes)‚ Lavinia Norman‚ Lucy Diggs Slowe and Marie Woolfolk (Taylor). Shortly thereafter they invited seven sophomores to join them in becoming founders and they are Norma Boyd‚ Ethel J. Mawbray‚ Alice P. Murray‚ Sarah M. Nutter

Advantages: Sulfamic acid is the fastest de-scaler - It dissociates into hydroxonium ions more readily in aqueous solution than the others‚ therefore giving a greater concentration of atoms that are able to react with the calcium in lime scale. It is safe to use because it does not produce chlorine gas [5]‚ which can be toxic. Sulfamic acid also has a low volatility. Disadvantages: Sulfamic Acid can be an irritant to eyes or skin and is the most expensive of the de-scalers. Q2) How these de-scalers

Formic acid is known to be the simplest carboxylic acid‚ and it is an important factor in chemical synthesis and occurs naturally. The chemical formula for Formic Acid is CH202‚ and is mostly found in the venom of bee and ant stings. Formic acid is clear and colorless with a pungent odor. Formic acid is used in many ways; Formic acid is used to preserve livestock. It is also sprayed on animal food and fresh hay to reduce the decay rate. It can also be used as a pesticide to protect bee
