Murder And Meal Lab Analysis Essay

Carbohydrates, lipids, proteins, and nucleic acids are organic molecules found in every living organism. These macromolecules are large carbon based structures. The macromolecules are assembled by joining several smaller units, called monomers, together through a chemical reaction called dehydration synthesis. The resulting polymer can be disassembled through the complementary process called hydrolysis.Carbohydrates are made of carbon, hydrogen and oxygen atoms in a 1:2:1 ratio. This means that for every carbon atom present in the carbohydrate there are two hydrogen

Customer C is responsible for murdering Fannin within Ernie’s Lunchroom. Through investigation and gathered evidence it can be determined Customer C is the main culprit for the murder of Fannin. Customer C’s involvement with this murder can be proven guilty due to the left hand dominance, leaving of footprints, and the proven alibies of the other customers.

This paper is based on an assessment of a patient. The assessment underlines the nutritional health status of the patient, by indicating that he is malnourished. This patient has few chronic diseases including hypertension, pernicious anemia, and depression. The mini nutritional assessment finding, labs, and interventions will be further discussed.

In the beginning of her article, Wendell asks the reader a lot of questions to make them think about how much we really know about our food we eat. This makes the reader understand either how much or little they know about the situation people can be in. When we buy food people usually don’t know how fresh something is, if the substance has any dangerous chemicals in it, where the place

Jon Kessel, the author of “Creating the Innocent Killer: Ender’s Game, Intention, and Morality”, a critical essay on Orson Scott Card’s Ender’s Game, has an interesting take on the morality of Ender’s character, and his supposed innocence in general. He compares many things to his own real-life childhood, as the main character is so relatable. Kessel’s essay is an extremely sharp-witted, eye-opening piece, as intended by him, that is important to the more ethically conscious audience. It also allows the reader to understand Ender’s Game on a much deeper level, offering inquisitive, and often antagonizing theories to question Card’s own internal conflict that he reflects in his writing. The purpose of his essay is to “examine the methods Card uses to construct… guiltless genocide, point out some

The purpose of this lab was to use chemical and physical tests to identify indicators of disease in synthetic urine samples. This lab tested samples for protein levels, glucose levels, and pH levels. In a normally functioning individual, proteins cannot pass through the glomerulus; therefore proteins should not be found in urine. However, in the nephrons of individuals with Bright’s Disease, the glomerulus no longer stops all proteins from entering the urine (Giuseppe et al., 2002, pp. 357–358). Bright’s Disease is characterized by a change in the permeability of the glomerulus, which allows proteins to pass through and since the nephron has no way of reabsorbing proteins they are passed into the urine (Giuseppe et al., 2002,

The purpose of this lab is to use control variables to help identify different macromolecules. Biological systems are made up of these four major macromolecules: carbohydrates, lipids, proteins and nucleic acids. Carbohydrates are sugar molecules (monosaccharides, disaccharides, and polysaccharides) which make them the most abundant macromolecule on the earth. Lipids (oils and fats, phospholipids and steroids) are insoluble in water and perform many functions such as energy source, essential nutrients, hormones and insulators (Lehman, 1955). Proteins are made up of peptide bonds holding amino acids together to perform biological functions like enzymes, antibodies, for transport and structure (Asmus, 2007). Lastly, nucleic acids

In class, a series of experiments were performed that pertained to the enzyme known as catalase, which converts hydrogen peroxide into oxygen. Due to peroxide being toxic to the tissues of both plants and animals, both possess the enzyme catalase, which breaks into two non-toxic compounds: water and oxygen gas. Enzymes are proteins that react to certain substrates to create a product, and continue doing so afterwards.

Bio Chem lab Report 04 Enzyme Biochemistry Group Member: Chan Man Jeun Duncan (16002621) Law Sze Man (16000478) Introduction Enzyme is a protein base structure substance in our body. It works at a biocatalyst that will catalyzing the chemical reaction, which helps to speed up the chemical reaction. Enzyme could only function in specific shape, and the shape of enzyme is depending on the environment, therefore it is hard for an enzyme to function well in an extreme environment. The aim of this experiment is to see can the enzyme functions normally in different environment(pH, temperature and salt concentration) via using starch solution, amylase from saliva, 0.5M HCl solution, 0.5M NaOH solution and NaCl solution, and using iodine solution

Being able to identify unknown microbes from systematic testing is what makes the field of microbiology so important, especially in infectious disease control. Using the testing procedure laid out by the microbiology field we are able to identify unknown bacteria present in our everyday lives, and along the way learn a lot about their characteristics that separate them from other types of bacteria. Being able to do this is vital in order for us to understand why microbes are present in certain places, how they are able to grow and what restricts their growth, that way they can be combatted if necessary. These techniques for determining unknowns are also important for isolating and testing infectious disease microbes in order to prevent spreading. Another important aspect of being able to identify unknown microbes is the

Unknown microbial #398 went through several of tests in order to identify its characteristics when isolated from a urine sample of Doris, a 64- year old patient with a kidney infection. To identify unknown #398, must prepare a working and a reserve stock by the inoculation from a broth culture and by quadrant streaking method on a PEM and EMP plates. The following test procedures were incubated at 37°C for 48 hours for observation and identification for unknown #398.

The first technique was to graph the correlation between the body’s advanced state of decomposition, and the pattern of daytime and nighttime temperatures. This technique let to the conclusion that she was killed from October 6 to 16. The second technique was to get soil samples, one from beneath the victim’s body and the other from an uncontaminated control sample. The results narrow the window to October 12 to 15. The last technique used was relatively new and involved using a freshly killed pig and using this pig as a “body double.” The result of this technique indicated that the victim was killed between October 9 and 13. Using three different techniques they obtained very similar data. The last piece to solve this puzzle was to identify the victim. They got a fingerprint from the victim but there was not a match in the database. They move on into the missing people report in which they found a woman name, Darlene Smith who matched all of their forensic evidence. They went into her house and got a fingerprint from a document that she had sign before disappearing and the fingerprint were indeed a match to the

After every 1 min take one drop from the test tubes and place then in the test plate that were

Haiti is considered the poorest and the most densely populated country in the western hemisphere. Because of its topography Haiti is susceptible to soil erosion. Over several years Haiti has faced, high population growth, prominent poverty, significant food scarcities along and alimentary challenges. While rapid population growth has dropped, natural catastrophes, political and societal havoc’s have led to the country’s intense rise in poverty. January 12 2010 an immense magnitude 7.0 earthquake hit Haiti with an epicenter about 15 miles west of the capital, Port-au-Prince. Over 300,000 people were killed and some 1.5 million left to live on the streets. The earthquake was measured to be the worst this region had seen in over 200 years. After

Everything can change from one substance to another, but the creation and the end of some things never happen .On a beautiful day on the fourth of December in 2015, the class of SNC1D5 started a lab on different kinds of molecules. The reason why we did this lab was to investigate the chemical and physical changes between different substances. Substances can change from one substance to another that have alternate physical and chemical properties by chemical reactions or with reactants or with heat. A physical change mixes up molecules but doesn’t hurt their inner structure. An example of physical change is ice turning into water due to heat because it didn’t change the substance’s material. A chemical change occurs when there’s a new arrangement
