Two bones meeting at a joint.

Answer 2

Answer 3

thats what i was thinking but i didnt know how the ligs and tendons worked

Answer 4

I think it is B. I don't think the last one is the answer because two bones would not be the actual fulcrum... it's more like the load.

Answer 7

right because thyd just bend

Answer 8

like an elbow

Answer 9

there needs to be leverage

Answer 10

So do you think it is B?

Answer 11

When the muscles contract, the bones are moved around the pivot formed by the joint. Granted, it is not stationary like a see-saw fulcrum but it is similar. A, B., and C are even less like the fulcrum.

Answer 12

Okay...I'll look into it.
