The American Cancer Society estimates that 18,300 Americans will be diagnosed with malignant brain, spinal cord and other nervous system tumors in 2003. Approximately 13,100 people in the United States will die from brain, spinal cord, and other nervous system tumors in 2003. Brain and spinal cord tumors occur most often in children younger than 10 years of age, whereas in adults, these tumors are most common in the third to fifth decades of life. Brain tumors form because, the body normally forms new cells only when they are needed to replace old or damaged ones. If something happens to...
will be diagnosed with brain cancer. Brain tumors are the second leading cause of death in the age group 15-34. Brain tumors are the second fastest growing cause of cancer death among those over age 65. Approximately 44 percent of all primary brain tumors are benign. Unlike most benign tumors when located on the brain they can cause death. Because of their location brain, tumors are difficult to treat. Brain cancer research is underfunded. ? The cause of brain cancer is still unknown. The cure rate for brain cancer is lower than that of most other types of cancer.

Prediction I predict that the higher the concentration of salt, the lower the mass the potato cylinder will become. This is because there is a greater concentration of water molecules inside the potato cylinder, so the water will drain from the cylinder by osmosis, to where there was a...

I will measure the volume of gas produced as the catalase in the potato tissue reacts with the hydrogen peroxide to create water and oxygen. I will change the temperature at which the reaction takes place, but to make the test a fair one I will keep the pH level...

Hypothesis: The higher level of concentration of the sugar solution, the greater reduction of the potato cylinder will be. Prediction: I think that the higher the concentration of the sugar solution, the bigger the length difference will be. This will be because the water molecules will flow out of...
