2.2.1 Food Testing with chemical indicators
Scientist use chemical indicators to analyze the chemical components of a substance. An indicator is a substance that changes to indicate the presence of a particular compound. This lab used chemical indicators to test for the presence of sugar, starch, protein, and lipids in three different foods that were listed in Anna's food diary. This lab required writing a detailed and reproducible lab using chemical indicators. The skill of writing and preforming labs is important in the biomedical sciences.
Glucose Tolerance Testing- Activity 2..1..1 Diagnosing Diabetes
Glucose Tolerance Testing monitors the amount of sugar in the liquid portion of blood called plasma. It is tested over a set time period and givers doctors information as to how the body utilizes sugar. This skill required the use of glucose paper and interpret the results. The results were then recorded and used to make a line graph in excel. This skill is important in the Biomedical Sciences because it requires the skill of interpreting results and putting them into a graph.
Activity 1.2.3 Gel Electrophoresis
After DNA fragments are cut by the restriction enzymes, they are mixed in a solution so they can be separated. This is done by passing the fragments through an agarose gel. The larger fragments don't travel as far as the smaller ones do. So the larger ones are near the top and the smaller pieces are near the bottom. In Biomedical Sciences, they work with DNA; whether it's solving crimes or performing DNA analysis.
Activity 2.2.4 How much energy is in Food?- Calorimetry
This lab required the skill of setting up and using an apparatus called a calorimeter. The calorimeter is used to measure the amount of energy in a variety of food samples; such as peanuts or marshmallows. The purpose of weighing and recording the temperature was to accurately calculate the amount of energy is in a food sample. This skills of calculating energy and using a calorimeter is important in the biomedical field. Food chemist and biochemist work with food to help better our understanding of nutrition and make us healthier.
Activity 2.2.4 How much energy is in Food?- Graph Experimental Data using Logger Pro
This lab required the skill of using the program Logger Pro. This program can record temperature over a set amount of time and create a graph from the data. The data is collected from a probe connected to the computer while the program is opened. This skill is important in the biomedical sciences because experiments often require the use of recording data in a new program. If food chemist want to figure out how much energy is in a food, then use this program to get data from the food sample.
Activity 3.4.1 Family Inheritance- Analyze Pedigrees
Activity 3.4.2 What's the Probability?- Analyze Pedigrees
Pedigrees are graphic organizers that show the occurrence of a particular trait form one generation to the next. They make it easier to visualize relationships within families and are used to determine the mode of inheritance of genetic diseases. This activity looked at Anna Garcia's pedigree depicting the occurrence of sickle cell anemia within her family. They are important in biomedical science by determining whether a trait is dominant or recessive gene. Pedigrees help couples who want to start a family predict what kind of genetic diseases their future offspring could have.
Activity 4.1.1 Path of Blood in the heart- describe blood flow through mammal heart
Activity 4.1.2 Anatomy of the Heart- describe blood flow through the mammal heart
This skill required describing the blood flow path through the heart as oxygenated blood is pumped to all the parts of the body. We investigated the basic structures of the heart and identify the major blood vessels that bring blood in and out of the heart's main chambers. A diagram was used to memorize the pattern of blood flow to and from the heart, lungs, and body. This is importance in biomedical science to help determine if something were to go wrong with the blood flow in the heart. The knowledge of blood flow in the heart is importance while repairing the heart back to functioning normally.
Activity 5.1.5 Bacterial Identification- Using/comprehending an Enterotube
This skill required the use and reading of an Enterotube. This test helped identify Gram negative bacterial samples by testing what growth media the bacteria will grow on and identify the end products of their metabolic processes. This system incorporates 15 standard biochemical tests combined in a compartmented tube designed to be run and viewed in 24-28 hours. After the incubation period, the results are recorded and translated into a five-digit number. Knowing the code will allow the unknown bacteria sample to be identified.
