Stem cells are the primal cells which develop from adult body tissues and embryos. These are present in the adult body through out their life. These are also called tissue specific or somatic stem cells. These are more specialised than embryonic stem cells. These stem cells are found in bone marrow, brain, blood and blood vessels, skeletal muscles, skin and the liver. Differentiation is the process where an unspecialised cell acquire cellular character which allows it to perform specialised functions. During embryonic stage, the cells of embryo make a number of cell fate decision that result in the decreasing capability eventually producing the specialised cells. Stem cells can divide and produce new cells, Hence they have the potential to be transplanted to the patient to treat medical conditions and disease. They are removed form the embryo where they exist as unspecialised stem cells and they will differentiate into any cell type. Specialised cells include many cells like nerve cells, blood cells, ovum cells etc. These specialised cells help in reproduction, energy metabolism, regeneration, information transfer etc.

Explanation:
its right trust me :D
I think the first one is right !.... but the for the other one it's B .
Answer:
lungs
left side of the heart (LA and LV)
to the rest of the body supplying the fuel that the body cells need to function
The body cells remove oxygen from the blood, and the oxygen-poor blood is returned to the right side of the heart (RA)which was the beginning of the blood circulation This circle trip is known as the circulation of blood.
Explanation:
The blood circulatory system is also known as the cardiovascular system. its is responsible for the delivery nutrients and oxygen to all body cells. It is made up of the heart and the blood vessels running through the entire body. the circulatory system is made up of the arteries and the veins which helps in the movement of blood from the heart and to the heart.
