When you are born, your bones are a soft, rubbery, and flexible tissue called cartilage. As you grow, most of your cartilage is replaced by bone. when it comes to bone marrow (spongy substance in the center of bones), red bone marrow fills the center of long bones as a child. Then it is replaced by yellow bone marrow as the child becomes an adult.
Babies have more bones than adults, the reason being that the bones have not fused yet. for example, the skull is in several sections and the bones in the hands and feet are not joined properly. They also lack kneecaps, and have cartilage instead. This is because they have not strengthened their knees yet.
For one, younge children have cartilage in their bones, that enables them to grow. Adults do noit have this.
When a baby is born, its skull is not fully formed, which is why you cannot drop a baby, as their head isn't fully protected.
This is because the missing parts are made out of cartilage, so that the head can be squeezed out of the mother.
Adults also have yellow bone marrow, unlike cildren. It is basically to store fat.
baby s bones are not developed as much as adult bones are in a new born baby,only the bone shafts are ossified ; the bone ends (epiphyses)are made of cartalige wereas by about the age of 18 the cartalige is replaced by bone and the growth is complete
Look at some clues here :
1. Abundance of cartilage vs. bone
2. Incomplete or lack of fusion between bones
3. Poor development based on lack of use
4. Large head size compare to the rest of body ( principle of cephalization)
5. Facial vs. Cranial parts of the skull
6. Frontal bone and the metopic suture
7. Fontanels
8. Pelvic bone
9. Spinal curvatures
The mature skeletal system is comprised of 60 percent calcium compounds and about 40 percent collagen which is a fibrous protein. Immature bone has more cells and much more ground substance.
Children have more bones.

A proglottid is mature when it has detached from the tape worm in order to continue the tapeworm's reproductive cycle. At maturity it is a sac of eggs with degenerated reproductive organs, Maturity in this case doesn't relate to reproductive capability, (as it would in mammals), it relates to the completed end product: fertile eggs. i think the the difference between mature and immature proglottid is that mature progllotid has mature reproductive structure while immature has till not mature reproductive organ
