Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow and the canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment and are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Hope this helps :))
A physical property is any property that can be measured without changing the composition of matter. Physical properties are used to observe and describe matter.
