Stem cells in human bone marrow can divide and differentiate to form various types of blood cells, such as red blood cells, white blood cells, and platelets.
Option a is false. Stem cells do not form totipotent embryos; they have the potential to differentiate into various cell types, but they do not have the ability to form a complete organism on their own.
Multipotent hematopoietic stem cells------> Myeloid stem cells------>Reticulocytes----->RBCs
It doesn't you are born with blood and cells witch form tissues witch form organs
The White Blood Cells form in the lymphoid organs.
Stem cells in human bone marrow can divide and differentiate to form various types of blood cells, such as red blood cells, white blood cells, and platelets.
Red and white blood cells produce in bones. The bone marrow produces the cells
Red Blood Cells (RBC) do not "form a scab", they are merely trapped in the scab during blood coagulation. Platelets, carried in the blood serum form the scab by sticking to the endothelium (inside) of the blood vessel forming a plug to end bleeding. Clotting proteins than begin to condense and form the hard scab. Human RBC do not have DNA and therefore cannot act in response to external stimuli like a cut.
blood is red due to the blood cells that form blood. there are also white blood cells but are not seen because of the value of the red blood cells of a greater number.
red blood cells are destroyed by macrophages in the blood to form heme and globin
in the bone-marrow
Option a is false. Stem cells do not form totipotent embryos; they have the potential to differentiate into various cell types, but they do not have the ability to form a complete organism on their own.

Yes they do.
no
A scab on the human body is a collection of partly dried red blood cells and mostly white blood cells. the white blood cells form on the outer layer of the skin to prevent future bleeding/stop the bleeding, and the living white blood cells on the inside of your body begin forming around the wound, repairing skin and flesh structure. All-in-all, a scab is the 'during' process of healing a wound.
Platelets form to help control the blood loss.
