Elvis Experiment Introduction: In this experiment we will determine how the difference in length and diameter of a blood vessel have an effect on the resistance of blood flow and how the viscosity of blood will also effect the resistance of blood flow in a blood vessel. Observation: My mom is a big Elvis fan and she always wondered how his health affected his death. Knowing that he had high cholesterol and high blood pressure I decided to do an experiment on what factors may have had an effect on

“Cell Transport Lab” Hypothesis: I hypothesis that there will be a movement of molecules out of the egg‚ and will move into the water solution. Osmosis will occur within the egg‚ and in the process the molecules of the egg will diffuse. Time (hrs) | Observations | Circumference (cm) | * 0 | * Egg is of normal weight and size * No membrane is being shown‚ and is almost perfect | * 14 centimeters | * 24 | * Egg has gotten larger taking in some of the water * Shell is soft

Catalase Experiment Research Question: How does the weight of a piece of liver (0.4g‚ 0.8g‚ 1.2g and 1.6g in this case) affect the amount of gas created after 2 minutes when combined with hydrogen peroxide? Aim: To see find out how the amount of catalase correlates with the amount of gas created when in combination with hydrogen peroxide. Materials: 15g of liver 25 ml of hydrogen peroxide 1 scale 1 bucket 1 100ml graduated cylinder 1 250ml flask with bung 1 50cm tube (able to fix onto top of flask)

An Experiment of Adaptation Introduction: Throughout history of time‚ organisms change in relation to their environment‚ consequently‚ adaptation is an essential property of life. This experiment is designed to test the adaptation of Drosophila melanogaster. This kind of insect is also called fruit flies‚ it has been widely used in scientific research because it has a short life cycle about two weeks and it is easy to keep large numbers of them (Manning). Two groups of this species will be used

1- What are three risk and threats of the user domain? Top risks are users and social engineering 2- Why do the organizations have acceptable use policies (AUPs)? The AUPs is very important to any organization. The organizations should have AUPs to a- Protect the organizations from any attack weather from inside or outside. The organization can do that by preventing the employees from downloading any services not needed that may be come with threat such as virus or any kind of malware.

Enzyme Kinetics Marcos‚ Nelissa S. Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines ABSTRACT The rationale of the experiment is basically founded in the concept of reaction rates as affected by enzyme‚ and how the enzyme works is competed by a competitive inhibitor‚ thereby impeding the forward reaction. In this experiment‚ o-diphenol oxidase‚ an enzyme that causes the browning in fruits‚ was extracted from banana and reaction rate of this was established
