Answer to Question 1

Regional floods occur due to heavy rains or rapid snowmelt that causes streams to overtop their banks because the water cannot infiltrate or discharge as fast as the precipitation. Flash floods occur because of surface conditions that limit or prevent infiltration, heavy rainfall, and topography. They occur with little warning, and unlike regional floods, they cause the water level to rise very rapidly and have very high flow velocities.

Answer to Question 2

About 30 percent of all Earth's freshwater is groundwater. However, when glacial ice is excluded, 96 percent of freshwater occurs as groundwater.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
