The ferns habitat I'm positive this is the correct answer.
The answer to this question would be more movement.
The amphiarthrodial joint is a joint that you will found in the rib cage. This joint doesn't have a synovial cavity and only allow a little movement.
But synarthrodial joints movement is practically zero. The example for <span>synarthrodial joint would be suture in your skull. Skull joint in adult can't move so its volume can't be changed.</span>
Is this a question or a statement ?????
