How come google ads are showing here?

Hi dear fellows, I just enabled Adbrite in my Blogspot site. Here: writing blog The ads right in every post is an Adbrite ad code. Can anybody tell me how then Google ads are showing up there? I dn’t quite understand, since there is no google ad code there. If you check the source, you will see there are only three google ad slots. Please tell me why it is like this. any issue with blogger or the Adbrite people linked up with Google? I hope this is not any violation of terms…
Very much appreciate any answers. Thanks.
