Reactants. Reactants are the substances that are needed for a chemical reaction to occur. Without reactants there are no products.
Genetically Modified bacteria can be harvested for Insulin using the process Mitosis and doing so they can asexually reproduce identically and make clones making them all have the insulin producing gene. If you would like a better explanation, it won't bother me if you ask:)
I believe the correct answer would be D. Hemocytoblast cells give rise to formed elements in the blood. These cells are stem cells for elements that are blood-cellular. They are obtained from the mesoderm and are located in the bone marrow. When these cells are divided into two cells, one of the daughter cells would be come a blood cell while the other will remain as a hemocytoblast to ensure that there is enough of this cell that is available. They are considered to be able to produce all blood cell types namely white blood cells, platelets and red blood cells. To do this, they undergo the process of haematopoiesis.
