Several questions to flash cs4

[FONT=Tahoma][COLOR=black]Hi everybody. My group and I are doing a project in school, and I have some questions to Flash I hope you can answer.[/COLOR][/FONT]
[FONT=Tahoma][COLOR=black]1) Is it possible to make a symbol which contains animation of a circle being rotated and scaled up and down? Or can a symbol only contain one type of tweening, and if so, how do I make it do both tweens?[/COLOR][/FONT]
[FONT=Tahoma][COLOR=black]2) Is it possible to make a symbol follow another object? For instance, we want the backgroundimage to be scroll’able to each side and in this image we want the before mentioned circles which follows the movement of the picture?[/COLOR][/FONT]
[FONT=Tahoma][COLOR=black]That’s it for now, I know I will probably have other questions later.[/COLOR][/FONT]
[FONT=Tahoma][COLOR=black]Bye, and thanks in advance[/COLOR][/FONT]
