Thank you have fun with your points
No i can type preety darn fast, so ill put up fourty points now, its due tomorow and i dont have enough time for the rest of my homw work can you help me at all?
Yes i totally agree but i have one problem how do i give you the 30 points i have been trying to find out how and have had no idea how.

Don't you think it took longer to type out these questions than to just look up the answers yourself? Because I bet they're in your notes or easily available in you science text book. Or just put the definition into google and you'll get the answers really quick.

HOPE THAT HELPS :D
It takes 1 hour to search for all these questions and these are right answers and i had search them very deep :D Now i deserve 30 points :D.
