<span>The answer is osteoid. It begins with unmineralized collagen fibers
and ground substance. Later it becomes a calcified matrix. The matrix is mainly

of bone causing rickets</span>
<span>Many resources come from living things. We use animals such as chickens, cows and pigs for meat. We use plants for numerous things. Plants are eaten and also we can make products from them. An example is cotton. We make clothes from that item.</span>
Scientists compare the anatomy, embryos, and DNA of living things to understand how they evolved. Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor.
No it couldn't happen as cellular respiration brake down glucose by the help of O2 to form ATP and co2 while this Glucose was first synthesized by the photosynthesis process without it there wouldn't have been any glucose for cellular respiration to take place
