Name: Danielle Title: Unknown Lab Report Introduction: There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics. The experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by Dr. Honer. The appropriate tests were prepared and applied. The

Introduction FIGURE 1 : N-Channel JFET The Junction Field Effect Transistor (JFET) is a three terminal device that consists of drain‚ source‚ and gate. The JFET is a voltage-controlled‚ constant-current device and a unipolar device. For this experiment‚ we used the JFET Self-bias circuit which in particular we use the n-channel. This kind of circuit is simple yet effective and is the most common biasing method for JFETs. The important thing to know is that the gate is essentially

zmosis The IB Lab Report Measuring osmosis 1. Introduction My experiment is about osmosis on a potato and if or the quantity of salt affects osmosis. I would do the experiment with 5 potatoes cut into squares all the potatoes weight the same so the weight can`t be a variable the I put the potatoes on 5 different plastic cups with different amounts of salt and then I weight them again to see if the quantity of salt affected the osmosis of potatoes 1a. Research question ¿Does the quantity

Bioinformatics Lab Report Hypothetical Phylogenetic Tree: Using a cladistic approach‚ we constructed a hypothetical phylogenetic tree of many different plant taxa by comparing their morphologies. We first decided to sort the various types of plants into groups based on morphological features. After sorting these plants into five different groups we began to determine how the plants differed from eachother in the group and what features set them apart. From this we started to create

Lab Report Enzymes (must be typed) Name: Amanda Gallegos Date: 2/15/15 Section: BIOL 101GL What is the Hypothesis of this experiment? (3 points) -The highest temperature will affect the reaction rate of enzymes. What is the dependent variable? (1 point) -Change of rate/product/color/absorbency. What is the independent variable? (1 pt) -The temperature. Explain in detail the procedure that you followed (including amount of substrate‚ enzyme etc‚ and the whole procedure including incubation times)

The objective of this lab was to prepare n-butyl bromide or n-bromobutane‚ which is derived from an alcohol and an acid. In this case‚ n-butyl alcohol and sulfuric acid were the reagents. There were two methods of distillation that was involved in this experiment. The first was by reflux distillation‚ which is used to speed up a chemical reaction without having the reactants/ products evaporate or explode. Data Table 1 indicates the amount of each reagents that was prepared for the reflux apparatus

Introduction In this lab we had to design a system that would test if changing the mass‚ angle of release and length would have any effect on the period of a pendulum. Hypothesis As the length‚ mass and angle of release change‚ the period (T) will change for each one of these factors.

Introduction: Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans‚ mitosis produces somatic cells that are diploid‚ which means they contain two non-identical copies of each of the twenty-three chromosomes. One copy is derived from the person’s mother and the other from the person’s father. Meiosis‚ on the other hand‚ occurs only in testis and ovary tissues‚ producing sperm and ova (eggs). The gametes that

the essential elements required for photosynthesis to take place. The “photo” part of photosynthesis is in reference to the fact that the process requires light. The simplest form of the photosynthesis equation is: H2O + CO2 ----light----> (CH2O)N + O2 As shown in the equation‚ photosynthesis produces carbohydrates‚ but more importantly‚ it produces oxygen. In 1937‚ Robert Hill discovered that chloroplasts in water could release oxygen if light and an electron acceptor are available. In his

flask. Under a fume hood‚ slowly add 30 ml of bleach‚ and oxidizing agent‚ to the mixture and stir for 20 minutes. Acetic acid will react with bleach to make it a better oxidizing agent and form hopochlorous acid. Hypochlorous acid will then oxidize cyclohexanol. The mixture turned cloudy during the process but clear up after a few minutes. The flask will be warm since this is an exothermic reaction. Next‚ the mixture will be tested using potassium iodide-starch test. If the test is positive then proceed
