Findings Analysis to determine the sex of our case study AFA was done using a physical exam karyotyping and PCR-based sex testing. The results from our physical exams on AFA showed well-developed female external genitalia‚ presence of breasts‚ no menstrual cycle‚ and no facial or chest hair. This led to a conclusion that AFA is a sterile female. The results from the Karyotype Analysis showed presence of 22 pairs of autosomes chromosomes and two X’s revealing that she is female. Lastly the PCR-based

Determining the Enthalpy of a Chemical Reaction All chemical reactions involve an exchange of heat energy; therefore‚ it is tempting to plan to follow a reaction by measuring the enthalpy change (∆H). However‚ it is often not possible to directly measure the heat energy change of the reactants and products (the system). We can measure the heat change that occurs in the surroundings by monitoring temperature changes. If we conduct a reaction between two substances in aqueous solution‚ then the

From the graph I can clearly see that Distilled water has a much larger concentration of water then the cell sap in the potato tissue. I can make this conclusion because the results show a big increase in weight of the potato piece. Meaning that water has moved from outside the potato into the potato due to Osmosis‚ proving that the distilled water had a higher concentration of water‚ as water moves from a high concentration to a low concentration. I can also see that the glucose

Procedure: Melting point of RCO2H Before observing the melting point of the unknown sample‚ the melting apparatus had to be standardized with a standard substance having the melting point of 151°C-153°C. After placing a small sample of the standard in a capillary tube and inserting the tube into the sample tube holder‚ the plateau on the device was set to 15°C below the expected melting point. After its temperature reached the plateau‚ the temperature increment was set at 1°C per minute‚ and the

I believe in determination‚ determination is something that everyone should have. I’m an athlete and I think that every athlete should have some sort of determination. Determination is having your mind set on something and fulling that to the best of your ability. Every person should set goals in their life and to be able to accomplish those goals you need to be determined. This year I ran cross country. I hate running but I was determined not to give up cross country just because I hate running

Determination of blood type Introduction: A blood type is a classification of blood based on the present or absence of inherited antigens substances on the surface of RBCs‚ these antigens are made by proteins‚ carbohydrates‚ and glycolipid‚ Now there are total of 8 blood type known for the international society of blood transfers ( ISBT)‚ Also 600 antigens are known for ISBT‚ Antigens are a type of protein (Y shaped) found in blood and it has a great role in the immune system to recognize any

the President’s Council on Bioethics published the ‘Controversies in the Determination of Death’. Within the publication‚ the Council discusses the various criterions that need to be met in order for death to be declared. The criterions include those of a neurological level‚ which have been observed for over three decades. Although there have recently been objections to the neurological criterion in regards to death determination‚ the Council decided to maintain the criterion. In keeping the neurological
