Objective: To extract caffeine from tea powder using polar - nonpolar solvent extraction technique. Theory: The technique used to separate an organic compound from a mixture of compounds is called Extraction. Extraction process selectively dissolves one or more of the mixture compounds into a suitable solvent. The solution of these dissolved compounds is referred to as the Extract. Here the organic solvent dichloromethane is used to extract caffeine from an aqueous extract of tea leaves

reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent.

Chelex Extraction and PCR Amplification of the Amelogenin Gene For The Purpose of Gender Determination. Abstract The amelogenin gene is a protein involved in the development of the enamel matrix. It is located on both the X and Y chromosomes in humans and can be used as a way to distinguish between males and females. Gender determination of a human has important applications in forensic science‚ prenatal diagnosis‚ etc. This can be done by Polymerase Chain Reaction (PCR) followed by gel electrophoresis

is involved with the cannon being fired then the force of gravity would cause the cannon to start to slow down‚ wouldn’t go as far and the direction or trajectory of the cannon ball would be a curved line going down. Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground &

Discussion: Extraction and crystallization- The purpose of this lab was to extract and crystallize compounds in a mixture using acids and bases. 1 gram of the unknown was dissolved into 30 mL of ethyl acetate. The mixture was then transferred to a separatory funnel. Using aqueous solutions of different pH we were able to separate organic acids‚ bases and neutral compounds from each other. Using three 10 mL portions of HCl‚ we reacted the HCl with the base in solution. This made it possible to
