Bilirubin Blood Test Lab Report

In this experiment, the hypothesis was that if living cells in beef liver is related to the pH of water, then the pH of liver will respond more like water when acid or base is added. According to the data shown above, the pH level declined (from 8 to 1) with the increase number of HCL (acid) drops added to tap water. Whereas the pH level increased ( from 8 to 13) with the increase of NaOH (base) drops added to the tap water. In contrary, the pH recorded in liver did not show this similar pattern as the tap water at all, in fact it showed a constant pH of 7 as drops of HCL and NaOH were added increasingly. The data for liver showed a slight decrease and increase in pH when acid and base was added beyond 20 drops, but was not as significant as tap water. Thus the hypothesis was refuted.

This test is used to detect the hemolytic activity in the bacteria. A darkish green color on the media around the bacteria would represent incomplete hemolysis. A transparent media around the bacteria colony represents complete lysis of the red blood cells. If no change is observed around the bacteria colony then the bacteria is non-hemolytic. For my

Blood type is the type of blood a person has that is passed down from the parents. The goal of this experiment was to find out if all the children were Mr. Johnson’s. The guided question was “Are all of Mr. Johnson’s children his biological offspring?” This relates back to the background information because the group had to find the blood type of each child and relate it to Mr. Johnson’s blood type.

There are four blood types found in humans. These are A blood type which has the genotype either AA or AO, B blood type which has the genotype either BB or BO, AB blood type which has the genotype AB, and O blood type which has the genotype OO. These genotypes show a combination of complete dominance and codominance. A and B traits are dominant to the recessive O trait, however, the A trait is codominant to the B trait. Each blood type codes for certain antigens. A blood codes for the A surface antigen, B blood codes for the B surface antigen, AB blood codes for both the A and B surface antigen, and O blood does not code for a surface antigen. Therefore to determine one’s blood type a test can be performed

The unknown project was an experiment where the student was given a petri dish of unknown bacteria. Tests were performed on it to identify the specific species. The purpose of the experiment was to learn about the identifying tests, and procedures in the identification of specific microbes. The reason the master plate was used to create a working plate is so that if the working plate becomes contaminated, one can resort back to the master plate for the pure strain of the bacteria and create a new working plate. The purpose of the first procedure, the gram stain, was to be able to dye and then distinguish gram negative and gram-positive cells on a smear. The second procedure, the citrate test is used to see if the bacteria can use citrate as

To test the blood, we first dropped two drops of blood into two spots in a micro-well plate, then we added the appropriate serum to both and mixed with a small stick. One side was labeled A, for the A Anti-Serum, and one was labeled B. If the A blood clotted it meant that the A antigen was found, and likewise with B. If both clotted the blood type was AB, and if neither clotted the blood was type O. Some errors made

From the handover received on Max’s current condition, the following care plan was constructed for the upcoming early shift.

Can the angle of a fatal blow be determined by the locations of the victim’s bloodstains? I will be comparing multiple bloodstains to one another and measuring them, trying to determine the angle at which I struck the “victim” (a kitchen sponge). This practice, called bloodstain analysis, is used by forensic investigators to determine the cause, position, and even time of death. I believe that by using trigonometry, I will be able to establish the angles at which I hit each sponge. I will repeat the experiment multiple times, and each blow will be delivered from a different angle.

This is a written reflection of a local health business and an online business. I will discuss how they market and promote themselves, whether they uphold their respective traditions and how the media has influenced their businesses.

Polyploidy variation in chromosomal number due to addition of one or more haploid sets of chromosomes.

An experiment was conducted in Mrs. Lynn's ninth period class on Wednesday, September 28, 2016. The purpose of the experiment was to determine why red blood cells appear smaller when sugar is added to the cell's surroundings. The independent variable in this experiment was the water outside the dialysis tubing (used to represent a cell) while the dependent variable in this experiment was the weight of the dialysis tubing after twenty minutes. Two beakers were filled, one with water and one with a lactose solution. Dialysis tubing that contained water was placed inside both of the beakers, then a timer was started. When the timer read twenty minutes, each cell was extracted and weighed. Each cell was then compared to its weight in grams before

Bilirubin is a component of the red blood cells, the erythrocytes, is made by the reduction of biliverdin by biliverdin reductase. [5] When bilirubin is released from the red blood cells into the circulatory system, the bilirubin will bind to albumin and become indirect bilirubin. This is to allow it to travel through the bloodstream as plasma is of an unsuitable condition for bilirubin to travel though unbound as bilirubin is water insoluble. The level of indirect bilirubin is one of the components measured in this experiment. The ideal range of indirect bilirubin concentration in the body is 0–20µmol/L as according to the practical manual.

1. Hemoglobin is the molecule that carries oxygenated blood from the lungs throughout the body through inhalation and deoxygenated blood from the body to the lungs through exhalation. When the hemoglobin is in the oxygenated state, it is in the R state or relaxed state. When it is in the deoxygenated state, it is in the T state or tense state.

Divine Woodfin Ms. A. Allison Honors Chemistry September 18,2015 What is the effect of different impacts on blood stains? The purpose of this project is to determine the effect of different impacts of blood on the stains that they leave. I chose to conduct this experiment as an extension of a previous experiment which only dealt with the amount of blood splatter within a given height.
