Question

what happens to the bones after growing up

• A. Number of bones increases
• B. Number of bones fused
• C. No change
• D. Bones become weak

Answer 1

The correct option is B Number of bones fused

Babies have more bones than adults because as they grow up, some of the bones fuse together to form one bone. This is because babies have more cartilage than bone. As a person grows up, most of this cartilage turns into bone in a process called ossification. By adulthood, the skeleton has just 206 bones.
