Green Man Lab Report

Begining by labeling 7 different 2.0 ml tubes 0 thru 6 for each compound. Then add 1ml of extract to tube 0. Then add 0.5 ml of DMSO to tubes 1 thru 6. Now make a 1:2 serial dilution from 0(pure extract) to 6(1:16)

The oxidation number of an atom of any free element is ZERO. Means to say there is only one kind of atom present, no charge.

Station one: Station one shows that when a small piece of magnesium metal is placed over the flame of the Bunsen burner, the magnesium metal ignites, giving off a bright, white light. Once the flame has extinguished itself due to the lack of fuel, the magnesium metal turned from a metallic strip to a crumbled white powder. It can be decided that station one is a combination (redox) reaction, as a new product is synthesised by the combination of two reactants. The reactants, magnesium and oxygen gas in the air bonded together to form the product of magnesium oxide.

Ionic compounds are soluble in water to a certain point depending on the compound. The level of solubility changes among different compounds. Some ionic compounds can completely dissolve in water and appear to be a homogeneous mixture. Although, some ionic compounds dissolve very little, and could be considered insoluble, since it does not dissolve fully. Depending on the compound, the level of solubility can be high or low. However, ionic compounds could dissolve to a certain degree. If the solution appears to be a heterogeneous mixture, many may assume through visual representation that it may be insoluble. As stated previously, the smallest amount of solubility should be considered. To confirm whether or not the substance is soluble, observe the efficiency when conducting electricity. Due to practical reasons, the slightest solubility could be considered insoluble by people.

Who Killed John Lee? A Biology 111 Forensic Investigation By: Lauren Mendoza Lab Group: Liz Sanchez and Estelle Makobi Introduction The purpose of this lab is to find out who is the culprit of the murder of John Lee. The victim was found in the CCA Lab Prep room on Monday morning.

The purpose of the PGLO lab was to be able to perform a procedure known as a genetic transformation. We used a procedure to transform bacteria with the gene that codes for a Green Fluorescent Protein (GFP). The actual source of the GFP gene that we used in this complicated experiment is the bioluminescent jellyfish Aequorea victoria. This protein causes the jellyfish to glow under a UV light that was provided in the dark. After the transformation procedure, the bacteria showed their newly acquired gene from a jellyfish and produced the fluorescent protein, which as a result, causes it to glow. If the bacteria glowed in the dark, that was the initial sign that the experiment was successful.

The atom of an element has electrons that are found around the nucleus in regions known as orbitals. When energy is absorbed by the electrons of an atom they begin to jump to higher energy levels. When this happens the electrons are in an excited state. However when the electrons begin to release the energy and drop in energy levels they emit electromagnetic radiation. If the radiation that is emitted falls between 400 to 700 nanometers then the electrons emit photons which we can see as visible light.

The purpose of this lab was to identify unknown bacteria cultures using various differential tests, and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways, each was used in a way to help recognize those specifics and identify the unknown cultures. The differential tests used to identify the unknown cultures were Gram stain, Catalase, Mannitol Salt Agar (MSA), Blood Agar, Novobiocin, Coagulase, and DNAse (Alachi, 2007).

When looking over my results, I found that the pH level increased from a neutral pH to a basic level of pH. The Miracle- Gro fertilizer that I used is supposed to have a pH of 7. This surprised me because I would think that adding a 10% fertilizer solution would make the water acidic. I thought that the fertilizer would be more acidic because when we learned about rivers, we found out that acid rain decreased the dissolved oxygen levels; also, Eutriporication results in low dissolved oxygen levels. Therefore I believed that the fertilizer would be acidic because of my background knowledge of dissolved oxygen in water. Regardless, the basic water killed the algae, elodea plant and the snails in the water. I also thought that eutrophication would occur in the water when

The experiments conducted for this lab report focused on water contamination and filtration. Experiment 1 was effects of groundwater contamination. Oil, vinegar, and laundry detergent were added to clean water with no means of filtration. The clean water was found to be contaminated. A filtration system consisting of cheesecloth and 60 ml of soil was created and the contaminated samples were filtered through it. The soil and cheese cloth did not affectively filter the contaminants. Experiment 2 focused on

The mean voltage of the battery terminals while connected to the identification resistors is presented in Figure ‎4 12. These samples have been pulled out from the voltage sensor of the PEB panel. The voltage decreased as expected from 12.53 to 12.5 during first 20 seconds of connection to the

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

Photosynthesis is essential to all living organism such as animals and plants. Photosynthesis is a process used by plants and other autotrophs to capture light energy and use it to power chemical reaction that converts carbon dioxide and water into oxygen, carbohydrates and water. (Textbook: Principles of Biology). The reactants and the products of photosynthesis are:

An association between enzyme production, gene copy number, and gene evolution was explored by conducting analysis of the salivary amylase enzyme, AMY1A gene copy number, and the ancestral starch consumption in Homo Sapiens (Tracey 2017, p.22). It was hypothesized that the relative amount of starch consumption was very high for my personal ancestral diet, thus my AMY1 diploid gene copy number in my genome and salivary amylase concentration would be significantly higher than the population mean. With a population of 28 subjects (n=28), individual saliva samples were collected and compared to a calibration curve to determine the approximate amylase concentration by analyzing absorbance values. Individual samples of buccal cheek cells were
