Passage¡± because it is necessary to be an adult. What is Rite of Passage? It means a ritual or ceremony signifying an event in a person’s life indicative of a transition from one stage to another‚ as from adolescence to adulthood. In the story ¡°Barn Burning¡± by William Faulkner‚ Sarty‚ who was the son of barn burner- Abner Snopes‚ he experienced his Rite of Passage at the end of the story. Although his decision leads to his father¡¯s death‚ it helps him to independent from his father. I think he made

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each

molecule structure to be triphenylmethanol. Introduction: The Grignard reagents are alkyl magnesium halides‚ R-Mg-X were first introduced in 1900. These reagents are usually prepared by reacting one atom with one molecule or by other means magnesium and alkyl halide in the presence of dry alcohol free ether.

The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight‚ hearing these could be attributed to loud noises or too much light going into your eye

Pour the top organic layer into an Erlenmeyer flask and dry with 2 grams of anhydrous magnesium sulfate. Observations: * The isopentyl alcohol and glacial acetic acid turned orange as soon as concentrated sulfuric acid was added. * As time passed while refluxing‚ the solution gradually became darker to a reddish color. * The final

The copper in the compound needed to be dissolved by using hydrochloric acid and then react with magnesium in order to only get copper left in the solution at the bottom of the beaker. The copper should be weighed and then compared with the other compounds (Table 2) in order to find the unknown. This was all performed in the

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas
