Scientists often perform experiments to check and recheck their work. They also redo these experiments to ensure correct results.
Answer:
The correct answer is c. production of white blood cells, red blood cells, and platelets.
Explanation:
Hematopoiesis is the formation of all types of blood cellular components and components of plasma like white blood cells, red blood cells, and platelets by hematopoietic system which involves the bone marrow, liver, and spleen.
First, the hemopoietic stem cell divides into common myeloid progenitor and common lymphoid progenitor. From myeloid progenitor RBC, platelets, basophils, eosinophils, neutrophils, and macrophages are formed.
Common lymphoid progenitor gives rise to T- lymphocytes, B- lymphocytes, and natural killer cells. Therefore the correct answer is c. production of white blood cells, red blood cells, and platelets.
Answer:
Mississippian fossils are abundant in portions of the Midwest and South and include vast beds of limestone and marble.
Explanation:
For example, the domed ceiling of the Jefferson Memorial in Washington, D.C., is made of Indiana limestone that was deposited during the Mississippian Period.By the end of the Carboniferous, reptiles had migrated well toward the interior of Pangea. These early pioneers went on to spawn the archosaurs, pelycosaurs, and therapsids of the ensuing Permian period. (It was the archosaurs that went on to spawn the first dinosaurs nearly a hundred million years later.)
That would be called <span>Defecation.</span>
