Answer to Question 1

D

Answer to Question 2

Venus has a thick cloud cover that prevents us from seeing the surface with visible light. Radar can map the surface, but its longer wavelength means the resolution is worse. Mars' atmosphere is thin enough that we can see surface detail from Earth. Also, we have landed several spacecraft on Mars, some of which have traveled over the surface. The few spacecraft that made successful soft landings on Venus were very short lived.

Did you know?

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.
