Ribosome packages nutrients and sends itto different parts of the cell
The correct answer is antigens and epitope.
An antigen is a substance which triggers an immune response in an organism. This can be either a foreign substance, such as a pathogen, or a specific part of the host organism (in this case this is an autoimmune response). The presence of an antigen activates a specific part of the immune system, called antibody. Each antigen has a specific antibody, which is tailored by the immune system accordingly. More specifically, the antibody has a specific structure, called paratope, which is complementary and binds like a key to a specific structure of the antigen, called epitope.
The correct steps of endochondral ossification is:
- A periosteal bone collar develops.
- spongy bone and the medullary cavity form in the diaphysis.
- The diaphysis center is vascularized and osteoblasts deposit osteoid over calcified cartilage matrix.
- The epiphyseal center is vascularized and osteoblasts deposit osteoid over the calcified cartilage matrix.
- The spongy bone forms in epiphysis.
<h3>Which bones grow by endochondral ossification?</h3>
Long and short bones, such as the phalanges and femur, arise from a cartilage model formed by endochondral ossification. Distinguishing between these two types of osteogenesis does not imply the existence of multiple types of bone tissue.
Endochondral ossification mainly forms in two stages: modifications of the hyaline cartilage that ends with the death of chondrocytes and invasion of osteogenic cells and their differentiation into osteoblasts in the cavities previously occupied by chondrocytes for deposition.
