Answer to Question 1

D

Answer to Question 2

Temperature is a measurement of the average kinetic energy of molecules in matter. Heat is the flow of kinetic energy between molecules. The three primary temperature scales are Fahrenheit, Celsius, and Kelvin. Fahrenheit places the melting point at 32 and the boiling point at 212. Celsius is divided into 100 degrees using a decimal system, with a melting point at 0 and a boiling point at 100. The Kelvin scale starts with an absolute zero, with temperature readings proportional to the actual kinetic energy. Melting point for ice is 273 and boiling point for water is 373.

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.

Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
