a sponge it doesn't move at all
no its a vertebrate because if it were a invertebrate then it would not be able to move you cans see they have back bones because when you hold them you can feel there back bone! :)
if he doesnt do it you do it.
I don't know exactly but if it can move the back, it does have a back bone. Did this help?
just talk really sweet to her. :) and if that doesnt work, you should move on.

if a girl knows you like her, chances are she will flirt back. if she doesnt flirt back...move on, she isn't interested!
the muscles are around or next to the bones, the contracting of muscles enables the bones to move. for example the muscles in your arm, when you move your arm up, the muscle underneath the bone contract (tighten) to push the bone upwards.
A gliding joint is one that moves back and forth and allows the bone to move::) har.har
yes if we didn't have spines we wouldn't be able to walk so they do.
become his friend or move on and find somebody better
if it is a fixed pulley, itself doesnt move. If it is a rotating pulley, its joint probably doesnt move.
Skeletal muscles move bones. A pair of muscles is required to move a bone -- one muscle to straighten the joint, and another to bend the joint.
