Answer:
the element oxygen , represented by the symbol o, is classified as a pure substance
Answer:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
Explanation:
Complex organisms need cells that can perform many different functions. they need to be supported on a cellular level. Without specialized cells you they won't be able to perform different functions.
Noncolumnar patterns of blood flow with the interconnected vascular network.
The standard model of cortical columns has network has tightly linked vascular network. It graph was carefully studied and theoretically analyzed. The results concluded that the microvascular that forms the subsurface, has formed a topology by the interconnected loops. And it is consistent with the boundary and the position of columns.
Furthermore, it was calculated that the blood flow patterns in the cortical column network are not related to the column's location. Instead, to limit lateral perfusion venues were penetrated that drained the sourced blood effectively by penetrating the arterioles.
Therefore, this analysis helps in understanding the effect of penetration strokes of vessels and its functional imaging on the viability of the brain.
