the four different pigments types of a leaf. As the filter paper with the solvent will separate the pigments in terms of solubility‚ a clear segmentation of each is expected to show off. As various chemicals were used in the whole process of this lab‚ certain variables might have influenced the results in terms of the purity of each chemical or purity of the used filtrate. Background The chloroplast‚ basically‚ is the organelle responsible for photosynthesis. Structurally it is very similar to

2014 Authored by: Cody Appleby‚ Gregory Harmeling‚ and Joseph Pernici May 26th‚ 2014 Lab section: C014 Monday 11am-1:50pm TA: Eduardo Castillo Work station 8 1 Abstract This lab consisted of three different measurements; measuring length‚ flow rate‚ and resistance. The reason for this lab was to use statistical concepts learned in lecture to analyze data and to become more familiar with the lab equipment. Repeatability measurements were taken on a bolt to get the total length‚ and

during the lab session Procedure Part A This lab was performed by the group members as they closed both low and high flow rotameters (Fig-2) and filled the tank with water. Then‚ the large rotameter was opened when the water in the tank had reached the internal baffle‚ so the flow from the tank was reduced by doing so. One member was in charge of adjusting the level of the water so it was always maintained over the baffle’s level during the lab (Fig-1). The first part of the lab was done

Biofuel Enzyme Kit Katie Adamson Biochemistry Laboratory‚ BIO124L 1/29/15 Abstract The objective in this lab was to determine the effects different conditions had on the enzyme cellobiase. We examined reaction rates in the presence or absence of an enzyme‚ the effects temperature and pH changes on the enzyme and the effects enzyme concentration and substrate concentration had on the enzyme. As expected results showed us that cellobiase works optimally when conditions are favorable. We see this

Adol Condensation Introduction: This reaction is carried out by adding benzaldehyde and acetone into a flask. The product created is a 1‚5-diphenyl-1‚4-pentdiene-3-one‚ which includes two double bonds‚ and two benzyl ring functional groups. This is a dehydration reaction that occurs twice in order to form the diene. After obtaining the product‚ via vacuum filtration‚ it will be recrystallized and then analyzed for purity by determining both products’ melting point. The two products will be

The Effects of Individuals’ Detection of Changes in Images on Reaction Time Abstract The purpose of this current study was to examine how individuals detected or noticed change when viewing images on their level of attentiveness. The experiment consisted of 22 participants who had to detect change across conditions for 20 minutes. These conditions were importance of change (marginal and central) and change type (color‚ location and disappearance and reappearance of images). These

The Effect of Metal Ions on Lichens Casey Stinnett ESC 1510 October 30‚ 2014 Introduction Lichens are a sybiotic association of fungus (mycobiont) and algae (Pediastrum boryanum . The fungus engulfs the algae‚ then supplies carbs‚ nitrogen‚ and vitamins while the algae photosynthesizes. This unusual relationship enables the lichen to grow in environments where neither fungus nor algae would normally be able to solely survive. They are found on every continent‚ ranging all the way from

A. ENG237-02: Transients in RC and RL Circuits 0. Introduction The objective of this experiment is to study the DC transient behaviors of RC and RL circuits. This experiment has divided into 6 parts: 1. Charging curve from measured data ( R = 10M Ω and C = 4 mF ) 2. Draw the charging curve by the graphical method 3. Discharging curve from measured data ( R = 5M Ω and C = 4 mF ) 4. Draw the discharging curve by the graphical method 5. Display of the charging and discharging

Boys’ Code of Conduct In the article “How Boys Become Men”‚ written by John Katz‚ he analyzes situations he experienced while growing up. Katz believes that boys become men by not showing fear or feelings and not ratting on others. As in the novel‚ The Other Wes Moore‚ both Weses are forced to become men at an early age. They experience events that push them to make decisions that make them grow and think like men do. Katz details the maturation process for boys‚ as the book‚ The Other Wes Moore
