Answer to Question 1

Answer: Primary forests are those that have not been substantially disturbed by humans. Humans have heavily exploited forests for wood products and wood to burn. The pattern of primary forests is one of places of little human population.

Answer to Question 2

Answer: The Nearctic Region consists of the non-tropic parts of North America. It is a relatively poor assemblage compared to other regions and is transitional between Palearctic and Neotropical realms. There is close similarity between Nearctic and Palearctic species because of the Bering land bridge.

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.
