KW about living things...

K]I know that all living things must have air to breath, must excrete waste, must have organs, and must have water.

W] I want to know why do living things need all the above, and how many things are there in the world (that are known to man).

My Goals....

My goals for this quarter are not to get anything under a six, to keep an organized notebook/folder, and my last goal is that i don't want to hand in any assignments late!
