Essay about Biology Milk Lab

Got Milk? Well, Austin Powers, Tracy McGrady, Serena Williams, Britney Spears, and even Elvis all do. But, do they know what they are selling in this Got Milk? Advertisements? The Got Milk? campaign was based on a milk deprivation strategy that reminded consumers how inconvenient it was to be without milk. The advertisment made milk a very popular drink because of its attractiveness not because of the nutrients and health issues. It has been believed by many that milk is needed to have a strong and healthy body, when actually milk can be extremely harmful and the nutrients needed for a good body can be found in many other sources.

The purpose of this lab was to test different substances using various procedures to see what biomolecules were present and ultimately find out what restaurant Anna Lyza had eaten at before she died. For the first control test, we used vegetable oil to test for lipids. So, if the solution does not contain lipids, it does not become translucent when placed onto a paper bag square and held up to a light. So, it is a negative result. However, in the presence of lipids, the solution will become translucent when placed onto a paper bag square and held up to a light. Therefore in this case, the result is positive. On the other hand, we used albumin egg to test for proteins in another control test. If the solution does not contain proteins, it will not experience any color change and so it is a negative result. When there are proteins existing in the solution, it will turn bluish/purplish and for this reason it is a positive result. Furthermore in the third control test, we used dextrose to test for simple carbohydrates such as glucose. If the solution does not contain simple carbohydrates, it will not undergo any color change and will remain a blue color. So, it is a negative result in this circumstance. If there are simple carbohydrates present in the solution, the solution will turn reddish and so the result is positive. For the last control test, we used starch solution to test

In the fast paced world of today, advertisers have to keep up with the times. One of the best ways they do this is through the Got Milk ads. Milk is a part of everyday life and the advertisers for Milk show this through modern tactics and popular celebrities. By putting familiar faces on magazine ads and using interesting T.V. commercials, companies sell their products. The ways in which they sell the products is not by just stating that their product is good, they appeal to the human emotions, ethics and most of all what is logical. There are many ad campaigns out there that strongly target one area, such as your emotions, but the Got Milk advertisers campaign has all three of these factors.

The purpose of this experiment was to find out the nutrient content of unidentified food samples and to use chemical reagents to see if the unidentified foods for sugar, starch, protein and fat (lipid) content. After comparing the color changes in each unknown substance then you will be able to see the amount of sugar, starch, protein or fat there is in the unknown substance.

Matos, Ribeiro and Guerra write about the benefits of breastfeeding and breast milk and how the antioxidants within the milk help strengthen a babies immune system. They provide a lot of scientific research and information on the different types of antioxidants, vitamins and other nutrients that are within breast milk.

Before the food lab experiment where we tested milk, crackers, bananas, and egg whites for simple sugars, starch, and proteins I expected to learn about what foods contained any of the three possibilities, if not all of them. The lab provided my group and I information afterwards that can further my education into macromolecules and biology as a whole subject. My group and I predicted that milk will contain simple sugars, crackers will have simple sugars and starch, bananas will have proteins, and the egg whites will contain proteins. If milk does contain simple sugars, during this lab when my group and I test, then the milk should turn from a blue color to a green, yellow, orange, or red color when heated. Crackers should have the same outcome as milk if it does contain simple sugars, but if crackers also have starch the crackers should then turn into a blackish color. We predicted that bananas contain protein and if so, then the solution should turn from a light blue to either a dark blue or a purple. Finally, egg whites are what my group and I finally predicted to contain proteins. If our hypothesis is correct, the solution should do the same as it does for the bananas.

After approximately 2 minutes, the test tubes were removed from the water and placed into the test tube rack for us to observe any changes to the solutions. The resulting states and colors of the test tubes were as follows: The negative control water was clear and blue in color; coconut milk was opaque with a dark orange precipitate in the bottom and orange through the rest of its solution; karo syrup was opaque with a dark orange precipitate in the bottom and orange throughout its solution; potato chips solution remained cloudy with no precipitate and was blue in solution; peanut butter solution was opaque with a brown precipitate in the bottom and brown through its solution; and the banana baby food

Throughout our lives we have been told that milk is good for our body and helps to toughen our bones. Drinking milk started when people domesticated animals for food, which happened around 7500 years ago in the central Balkans and central Europe. By that time consuming milk was not as common as it is today. It was only farmers in some specific regions that were using cow’s milk. Milk’s market grew the mass production of meat in the 15th century. Afterwards in the 17th century, the idea of eating out and going to restaurants was born and fast food industries, started using animal’s meat for producing their meals. The rate of milk users grew with the rate of meat users and milk’s market got bigger and bigger every day. Mothers

We then recorded the initial color. We placed each tube in boiling water for one minute and recorded the color results and gave our conclusion. To test for starch using Lugol’s solution, we reused the test tubes and added a squirt of the solution. We recorded the final color and then our conclusion for each content. To test for lipids using paper towels, we placed a drop of solution and we let it stand for one minute. We then recorded our observation, if it was dry or not dry and wrote our conclusion for each sample. To test for proteins using Biuret’s reagent, we added a squirt of stock solution plus a few drops of Biuret’s solution. We wrote the initial color. We then shook the solution and waited for two minutes before recording the results. After the two minutes, we wrote the final color and conclusion for each content. For the unknowns, we wrote the odor and appearance of each content and then tested the benedict’s, starch, lipid, and protein test and wrote our conclusion.

The results obtained matched what was expected when the experiment was started. The procedure was successful in the fact that the components of the milk were separated and the qualitative tests went

How are you? I was going to send you a message for weeks now, but with the baby things are pretty hectic and I am not always able to stay on top of them. I just want to thank you for the great help your classes are for me as a new mom. If it wasn’t for your support and guidance I am not sure I would have patience to stick breastfeeding Evelyn! Now when I am back to work I am so happy I am able to pump milk and feel the connection with my baby even with being away from her 8 hours a day. It was when I watched the Breastpumps and Briefcases I realized I can do it, no matter how intimidating it might seem at first. The Evenflo pump made the pumping so much easier too! I think I am able to express more milk with it than with

During the Cold War, the Soviets were trying to spread communism throughout Europe and Asia by exalting its achievements, and undermining democracy. Part of their approach was by launching ‘Hate-America’ propaganda. “As the Cold War intensified, the Truman administration launched an aggressive “Campaign of Truth” […] to counter the Soviet Union propaganda machine (Ubah, 2012).” The Campaign of Truth was created to help convince the world that the United States has “no purpose of going to war, except in the defense of freedom. (Vaccaro, 1950)” Truman encouraged the media to show the world that the United States was ‘wholly dedicated to the cause of peace (Vaccaro,

Hi, Kathy! Believe me when I say I got confused too when I reread my entry (hahaha). On my third sentence about the classical conditioning concept, I meant to say the “UCS” or the unconditioned stimuli, is basically something that is causing some kind of unlearned response. In my son’s case, the milk was the unconditioned stimulus, and when he fell asleep after a glass of milk, that was his unconditioned or unlearned response since it was elicited by an unconditioned stimulus (the milk) before I was able to condition him. I couldn't agree with you more, learning about the human mind is truly fascinating. It constantly makes you pause and think and then you’re left with awe by its amazing capabilities. I also love how there is little difference

The method that we used in our experiment deals with a feeding station. An outdoor feeding station was established in Colchester, Vermont on Saint Michael’s College campus. The station was located in a field across the street and behind an astronomy tower surrounded by trees. Our class chose to use red, green, and purple as the prey colors. After a group discussion took place on which colors would best fit this was our conclusion. We chose to use green as the palatable prey, purple as the mostly palatable, and red as the distasteful prey. The mostly palatable prey consisted of ¾ palatable, while the mostly distasteful prey only consisted of ¼ palatable. Flour and lard were the ingredients in the recipe that we used for the prey. The addition of quinine sulfate was given to the distasteful prey to add to the repulsive reaction of the predator (Banschbach, 2012). Next the prey was then colored according to the chosen colors by our class. The red coloring was created using two bottles of red dye in increments of 20 drops, while the green coloring was created using 100 drops of green dye in 25 drop increments. The purple coloring was created in class on the same day but the data for replicating the purple pigment has been misplaced. After the prey was colored the class cut the floury lard prey into roughly (6mm) sections long. They were then labeled in accordance to their palatability. We then randomized the arrays of
