The order is calcification of matrix >> cells differentiate into osteoblasts >> formation of the primary ossification >> osteoclasts break down the spongy bone >> formation of the secondary ossification (5,3,1,2,4). It is a fundamental process.
<h3>What are osteoblasts?</h3>
Osteoblasts are cells of the bones, which act to generate bone matrix and modulate the process of mineralization of the skeleton.
Endochondral ossification refers to the mechanism through which the cartilaginous bones generate longitudinal growth.
This mechanism (endochondral ossification) is fundamental during fetal/embryo development.

Pulmonary valve - connects right ventricle and pulmonary trunk (which divides into right and left pulmonary arteries). It is a semilunar valve
Answer:
Photosynthesis takes in energy from the sun, CO2 and H2O and produces Glucose(don't know formula), O2 and H2O. This means the water is needed for the reaction but isn't transformed. This means that in areas with greater average rainfall, plants generally grow faster.
Please help with my recent questions if this helped. :)
A layer of smooth cartilage at their ends, which cushions the bones and prevents them from rubbing directly against one another. The whole joint is also enclosed in a synovial capsule, which is full of synovial fluid. The synovial fluid acts like the oil in an engine, lubricating the joint and preventing the cartilage from becoming worn down.
The correct sequence of levels is shown by choice A.
