Doc. Anthony Miller, a physicist, and an engineer, with him Doc. Stephen Strange who had the same expertise as Doc. Anthony Miller. They were transported to Area 51 which was a secret military facility, they were brought there to work on a project.…
Goals The goal of the lab was to investigate the properties and structure of an unidentified compound that was discovered in a local landfill. The group was called in to help determine the chemical and physical properties of the compound so we can let the people of the town know so it can be taken care of properly with or without further precautions to be taken. Another goal of this project was to devise the synthesis of the unknown compound. Experimental Design In order to determine the correct identity of our unknown compound, we first started with a couple preliminary tests, which include physical state and smell.…
Materials. Numerous substances in the experiment were used. The most frequently used was the unknown due to the need to test its physical and chemical qualities. When a solution of the unknown was made, 1.000 g of the unknown and 1.0 mL of water was used to make it. To test for the possible ions, 1.0 mL of silver nitrate and 1.0 mL of nitric acid were used for the ion test.…
The study of microbiology requires not only understanding the microscopic organisms, but also the understanding of lab techniques and procedures used to identify, control, and manipulate microorganisms. The identification of microorganisms is not only important in microbiology lab, but also in the medical field to identify an agent of a disease that will help treat the patient by using the correct antibiotics to kill off the host. In this unknown lab report, techniques and procedures learned in the microbiology laboratory during the semester that was performed to test ones practical understanding of microbiology. The sole purpose of the unknown lab is to demonstrate understanding of the experimental methods and lab techniques learned during…
An unknown sample #18 was obtained on November 6, 2017. The sample came in a glass test tube with a cotton swab that contain the unknown sample. To find the identity of the unknown sample, we had to conduct several biochemical tests to eliminate and narrow down possible organisms that fit the biochemical description to accurately identify our unknown organism of interest. These biochemical tests provided insight on the physical color retention of our unknown sample, and through’s the unknown organism’s ability to break down tested compounds to determine if it had the corresponding enzyme that would allow it to do so. The testing of unknown organisms to accurately discover its identity is crucial in the field of health science.…
A pure substance has been isolated in the laboratory. Based on the two characteristics below, how 22)…
The focus of this lab was to identify an unknown organism based on its characteristics and the results from each of the tests. There will be various of test to choose from in order to identify the unknown organism, which will eliminate numerous possibilities and narrow it down to one. All the fundamental skills that we have learned and practiced in the lab will be used to perform on our unknown such as aseptic technique, microscopic examination, the use of differential media, and determining if it’s positive or negative. Performing aseptic techniques is the most crucial step that requires the utilizing of transferring, inoculating, and storing bacterial cultures and media. Aseptic technique is defined as procedures that prevent contamination…
What Does Luminol Do? Luminol is used to reveal traces of blood in crime scenes, using a light producing chemical reaction, between many chemicals, and hemoglobin. It is a powdery compound made up of carbon, hydrogen, nitrogen, and oxygen. Mixing C8H7N3O2 (luminol) with H2O2 (hydrogen peroxide), causes it to become a liquid.…
Problem People with diabetes who cannot make their own insulin. Making synthetic insulin for these patients due to allergic reactions from animal insulin such as from pigs. Introduction The pancreas produces several hormones which balance the sugar (glucose) and salt levels inside the body. One of these hormones produced by specialized cells (beta cells) is called insulin (a small protein).…
Truc-Nhi Do Separation of a Mixture The purpose of this lab was to separate a mixture, calculate the percent composition by mass, and find percent error. I first started out by taking the mass of each component of the lab. I used the infiltration method to allow the salt and water solution, a blended mixture, to pass through the filtration paper and into the beaker. A trick to know if something is a solution is to see is it has the aqueous sign (aq) in the formula, like NaCl(aq).…
The approved request dated November 12, 2015 to create the position(s) Laboratory Specialty Analysis (RD 11-15; RD12-15) indicated a salary range of $35,000.00-$55,000.00 annually. During the recruitment process we identified a candidate that exceeds the qualifications for this position. The candidate possesses professional experience, critical to the execution of complex tasks involving various NIH grants. Specifically, the candidate has over 20 years of post-graduate expertise in virology, molecular and cell biology techniques, nine years of working experience with antigen/ antibody related multiplex immunoassays, with a Master’s degree in Microbiology. The candidate also has hands on experience with: • SDS-PAGE, southern, northern and…
These results do not make sense, which indicates that there was a personal careless error. Some personal careless errors might include not being able to completely dry the flask. These results refute the hypothesis since the density obtained in the lab and the accepted density did not…
In order to determine the identity of two unknown bacteria, I performed a series of experiments over several days. To begin this process I created a dichotomous key that I utilized as a guide to perform a series of inoculations, while using both selective, and differential media. The series of inoculations eliminated bacterium based on test results until the correct bacteria were both positively identified. On day one of this process I received two bacteria, one labeled 7A and the other labeled 7B. I began the experiment with thirteen possible bacteria.…
The purpose of this lab is to understand the effect that dissolved impurities will have on the freezing point of a mixture and what additive will affect the the freezing point the most. The freezing point of a liquid is, the point of a substance when the temperature of the solid and the liquid is equal. When water freezes the water molecules become organized and come closer together forming crystal particles of ice. When a solute (like salt) and a solvent (like water) mix together the salt becomes an impurity and makes it so the solution can’t crystallize.…
Slime is made by mixing together borax, glue, and water. Depending on the amount of borax added to the mixture will determine the density of the slime. For our experiment in class the independent variable was the borax. The dependent variable was slime. The control group was glue.…
