A because it explains the differences
Acorn worms look nothing like people; the worms have no limbs and breathe through slits in their guts. But they share approximately 14,000 genes with humans, scientists found, comprising about 70 percent of the human genome
The answer is A. Class, because the divisions get smaller and smaller as they go down. Class is before Order so the division would be bigger.
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>
