Murder And A Meal Lab Report Essay

Our results showed mainly sugar, oil, and starch in the happy meal. I observed the color changed in all the tests, but the protein test. My hypothesis was “I predict the McMush will have all the biomolecules

2. Four unknown samples were included in the lab kit: flax seed meal, potato starch, egg whites, and dried milk. Using the results of the biochemical testing, determine which number corresponds to the correct unknown. (8 points)

The main goal of this lab was to figure out what a murder victim's last meal was, so we could question the people that the victim last came in contact with. Our materials included a brown paper bag, a stirring rod, pipettes, test tubes,biuret solution, bro blue solution, vegetable oil, 5% gelatin solution, 5%glucose solution, 5% starch solution, and the contents of the victim's stomach. We started with a positive control test of each solution. For the positive lipid test we spread a small drop of the vegetable oil onto a paper bag and held it up to the light, the vegetable oil soaked in and became transparent. For the positive proteins test we added a full pipette of 5% gelatin solution into a test tube along with 5 drops biuret solution

Therefore, this is where all solutions are extracted in ethyl alcohol or as the control in the experiment. The following tested for low concentration (pale color) of lipids: wheat flour, white flour, soy flour, egg yolk and the unknown A3. This is because these certain breads with flour have a high content of protein which lowers the content of carbohydrates, therefore has a low lipid value. Soy flour and egg yolk, especially, have the highest protein. Solutions such as cream, honey, margarine, salad oil, skim milk, coconut milk, 2% milk, whole milk, soy milk and butter varied from medium to high (strong) amounts of lipids present. Ethyl alcohol and egg white had none present.

Then we added 5 drops of Lugol’s solution and recorded results. Discussion: The results of the class were: Burger: Positive for fats/oils, negative for all the other tests, three groups got positive for protein. The data says that the burger has a low amount of protein in it. When we know that it has a higher amount of protein.

We tested for simple sugars, starch, protein, lipids, and pH.

A good law should be clear so both the judge and jury can apply it in

The objective in this experiment was to detect saccharides in different samples. The null hypothesis constructed is when a ketone and an aldehyde are in the presence of Benedict’s reagent or Lugol’s solution the appearance of the sample will change. The samples that were chosen to test consisted of distilled water, glucose, sucrose, bread, and salad dressing. The negative control of this experiment was water, and the positive control for this experiment was glucose. The independent variables of the experiment are the Lugol’s solution, and Benedict’s reagent. The dependent variable of the experiment are the ketone and aldehyde color change.

The purpose of this lab was to identify the presence of macromolecules in the food we eat and include in our diet. The three different macromolecules we tested for include carbohydrates, better known as sugars and starches, lipids(fats), and proteins. The results of such tests were not surprising as the contents used, typically contained only one of the products tested for. For example, when I tested albumen(egg whites) for protein, it confirmed positive. In contrast, potato juice- another of the contents- did not contain enough protein for the test to prove positive.

I believe the motion to suppress should be granted. The officer was on the right track with this encounter until the search and discovery of the 3x3 inch “container” in Tommy’s pants back pocket.

The lab 's intention was to discover particular nutrients in an array of foods, typically found in the American diet. Of course, humans need a certain percentage of carbohydrates, fats, and proteins for preserving energy. Before beginning the study, research was needed. The authors stated that while it 's impossible for energy to be made or destroyed, it can change form. Energy can be found in carbohydrates, lipids, and proteins. Carbohydrates, such as starch and glucose, store energy. Lipids (oils and fats) have double the amount of energy as carbohydrates, making them ideal for an energy boost. Important lipids, like polyunsaturated fats, contribute in regulating blood clots and maintaining healthy cholesterol levels. Proteins are vital in most physiological processes. Simple and complex proteins are critical in accelerating reactions. In this lab, there were three hypotheses: Does food coloring affect the nutritional analysis through reagent testing; what food item has proportional composition for all six food compounds; and are foods that have proportional composition for the six food compounds equate to the most reliable source of energy. Reagents were used as indicators to detect the presence of certain nutrients, with the reagents changing the color of the known solution, resulting in a specific color indicating the positive response. Each of the food

“Any country that accepts abortion is not teaching its people to love, but to use violence to get what they want,” by the religious sister Mother Teresa. This quote shows that places where abortion is legalized women have the freedom to make abortion behind the name of law without feeling pity on their unborn baby. Based on USA abortion statistics, women give three reasons why they choose abortion. The statistics show that, “3/4 say that having a baby would interfere with work, school or other responsibilities; about 3/4 say they can not afford a child; and 1/2 say they do not want to be a single parent”(Loxafamosity Ministries). However, these reasons are not enough

     The Nazi's were infamous for their cruel and unusual experiments on humans. Although they played a small part of Nazi Germany's attempt at racial hygiene, these experiments desecrated and exterminated thousands of humans (Lifton 269). "The Nazi medical experiments of the 1930's and 1940's are the most famous example of recent disregard for ethical conduct " (Polit & Hungler 127). For the sake of science, thousands lost their lives "I have no words. I thought we were human beings. We were living creatures. How could they do things like that?" (Auschwitz survivor as quoted in Lifton 269). Was it really science, or was it murder?

“Hello—is this the uh, anonymous police tip line? I think I have some information regarding the murder of that kid, two days ago. You have to understand, I – well, I wasn’t in my right mind. An unreliable witness they’d call me, but I’m fairly sure of what I saw. There were four guys - no five – darting from the alley that he (Andy) was found in. I don’t remember the time, it was probably around eleven. Anyways, they came out of there looking smug and I heard one yell “That’s for you Royal”. I’m not sure exactly what it meant, but that’s what was said. I could have helped him, I saw him and I thought nothing of it. Of course, alcohol was involved. It was a rough night. I didn’t even recall what happened until it came back to me while the
