Mitosis and cell differentiation leads to the creation of red blood cells in the body from bone marrow stem cells by a process called Erythropoiesis.

Explanation:

The process of development of red blood cells from bone marrow stem cells is called as erythropoiesis. The process is enthused by lower amount of oxygen during circulation, which is sensed by the kidney, after which it starts secreting a hormone called erythropoietin. In production of RBCs, the erythropoietin provokes the development and differentiation. All this phenomenon happen inside the Bone marrow. Throughout the creation of RBCs, there undergoes a sequence of mitosis and differentiation.

Why? from the smallest single celled organism to the tallest tree, all life model 1?

arsen [322]

From the smallest single celled organism to the tallest tree all life depend on the properties and reactions of four marcro molecules which are carbohydrate, protein, lipids and nucleic acid.
This is because, these organic molecules are the building blocks of all living things and they are responsible for most of the structure and functions in the body.

Answer:

Blood sugar regulation in a diabetic patient is done by

Injecting prescribed quantity of hormone insulin after definite time intervals.
Consuming prescribed amount of sugars.
Injecting glucagon to maintain blood sugar level if alpha cells of the pancreas are also non-functional.

Explanation:

The concentration of sugar in the blood is regulated by the hormone, insulin, produced in the pancreatic beta cells in normal person and injected from outside in a diabetic person.
When the concentration of glucose in the blood is high, the insulin signals the hepatocytes to express their glucose transporters to take up the excess glucose from blood and convert them to glycogen.
When concentration of sugar in the blood is low, another hormone called glucagon, released from the alpha cells of the pancreas, signals the liver to carry out glycogenolysis (breakdown of glycogen to glucose) and release the glucose into the blood. This would maintain the glucose level in the blood.
In a diabetic patient, usually the beta cells of the pancreas are affected but not the alpha cells, so the glycogenolysis can occur in the body spontaneously.
But excess injection of insulin should also be avoided as that can cause the blood sugar level to come down below normal.
