Bakery The apple is the pomaceous fruit of the apple tree‚ species Malus domestica in the rose family Rosaceae. It is one of the most widely cultivated tree fruits. The tree is small and deciduous‚ reaching 5â?"12 m tall‚ with a broad‚ often densely twiggy crown. The leaves are alternately arranged simple ovals 5â?"12 cm long and 3â?"6 cm broad on a 2â?"5 cm petiole with an acute tip‚ serrated margin and a slightly downy underside. Flowers are produced in spring simultaneous with the budding

A. Title – Acid-Base Extraction with Separatory Funnel B. Introduction – The main objective of the experiment was the extract an acid‚ a base‚ and a neutral compound from a 2:1:1 compound of benzoic acid‚ p-nitroaniline‚ and azobenzene. In theory‚ an extraction technique based on phase distribution should allow two immiscible solvents to separate with a portion of the solute distributed into each. Using a separatory funnel‚ acids were extracted with bases (NaOH)‚ and bases were extracted

Purpose This experiment deals with separating substances. The objective was to become familiar with the methods of separating substances from one another using decantation‚ extraction‚ sublimation techniques. Brief Introduction This experiment was set to teach research students different methods of separating substances from one another. Materials that are not uniform in composition are set to be impure or heterogeneous and are called mixtures. The separation of the components of mixtures is

Drosophila Melanogaster feed on fresh or decomposed fruit. We use a 1:1 ratio of instant medium to distilled water for the medium in culture vials that the flies will have to develop in. After making the medium‚ they have to be sprinkled with one or two grains of dry yeast to feed the flies. For the P1 and

Preparation of SKEO The extraction of S. khuzistanica was performed by hydro distillation and clevenger apparatus for 5 hours. Once extraction was completed‚ the resulted essential oil was dehydrated using sodium sulfate (Merck). The essential oil was stored at temperature of 4ºC until using (12). In order to provide different concentrations of the extract‚ Dimethyl sulfoxide (DMSO) was used. Gas chromatography/mass spectrometry analysis of essential oil Isolation and measurement of the sample
