I have a Question/Answer thing, no mods

Questions are:

• What animal barks? (a ___)
  
• What company created Android (and also runs the largest search engine on the Internet)?
  
• What is the name of the planet we live on?
  
• What animal quacks? (a ____)
  
• All people have a mother and a ______?
  
• What company makes the iPhone (one word answer)?
  
• The ___ rises in the morning and sets at night?

In addition, I have a few required fields during registration like the user's CPU, hard disk, RAM, graphics chipset, but they are just putting jibberish in there that's how I differentiate the real people from the spammers and delete them
