The population is getting bigger every minute. We use a lot of electricity. Oil and Coal are one of the big ones that are examples. We uses billions of it each year. After a certain amount of time around 2088, there won't be a lot let because we aren't thinking of conserving it .
Answer:
d. FGF2 signaling, splanchnic mesoderm
Explanation:
Hemangioblasts are the cells that serve as common precursors for blood vessels and blood cells. The hemangioblasts develop from mesenchyme and can give rise to angioblasts (to serve as precursor cells for blood vessels) or pluripotent stem cells to serve as a precursor for blood cells.
The basic fibroblast growth factor (FGF2) is one of the three factors required for initiation of formation of blood vessels. The basic fibroblast growth factor (FGF2) is required for the development of hemangioblasts from the splanchnic mesoderm and their differentiation into angioblasts.
