Wikipedia A blood donation occurs when a person voluntarily has blood drawn and used for transfusions or made into medications by a process called fractionation. Blood donation benefits extend beyond those who receive life-giving blood. Donors also receive numerous health benefits. Blood donation benefits to donors include: • Free health screening: Every time you give blood‚ a medical technician‚ doctor or nurse will check your blood pressure and give you a free health screening.

Introduction: Diffusion and osmosis are passive processes of transport. Passive transport involves no disbursement of energy by the cell. Diffusion movement is from high concentration to low concentration‚ which the driving force for this type of movement is kinetic energy particles themselves. Which crystal (Methylene blue‚ solid or Potassium Permanganate KMnO4-purple) will move further than the other due to the driving force (kinetic energy)? My prediction is that Potassium Permanganate KMnO4-

Juan Villacis COMM 1402-02 December 9‚ 2013 Title: MORE PEOPLE SHOULD DONATE BLOOD. I. Introduction A. Attention Getter: How many people have donated blood before? Does anybody know how many people can be saved by one donation?

AHP216 04/16/13 I. Introduction: The purpose of this experiment is to observe the osmosis reaction in a potato with salt and water. In cooking cooks will soak their cut potato’s in water if they will not use them immediately. This allows the potato’s to be used later without turning color. The experiment shows the flow of water through the membranes of the potato with salt over a period of four hours. II. Objective: The reaction of the potato to the side submerged in water and the half excavated

solution is higher than the concentration in the potato cubes‚ the percentage of weight change in potato cubes will be higher (positive). If the concentration of the salt solution is the same as the concentration in the cell‚ there will be no net movement of water through osmosis therefore there will be no percentage of weight change in potato cubes 2) The osmolarity of salt within the potato cubes lie between 0.8% and 1.0%. Thus saying‚ solutions of salt ranging from 0.0%(distilled water) to 0.8%

of nowhere‚ someone run through a red light and crashed straight in to you. You end up in the hospital‚ needing a blood transfusion. The scene is all too real and it happens every day. In a single car accident‚ a person could need up to 100 pints of blood. The average person can donate 3 pints every 56 days (redcrossblood.org). This is why‚ today‚ I urge you to go out and donate blood. I know some of you may hate the thought of needles or think that giving blood won’t really help. But‚ please consider

she carries the sickle cell trait and wants Davon screened for it. Davon may have the sickle cell trait. I would say that it would be hard to determine if Devon has a blood disorder because he has no symptoms. I do think that Devon is at risk of having sickle cell. Sickle cell is a disease that is inherited. African-Americans are at greater risk for the disease than any other ethnic group. Sickle cell is caused by genetic abnormality. It is diagnosed by a blood test. The blood test measures the amount
