Umbilical cord blood is a rich source of stem cells. which possible advance in biology would most likely be a result of performing research with an individual’s banked cord blood? creation of a novel cancer cell line to test anticancer agents creation of a personalized cell replacement therapy for the donor creation of a skin graft for an unrelated burn victim creation of a culture to produce vitamin e

Ans.

Umbilical cord blood is remains in umbilical cord and in placenta after the birth of child. Cord blood is collected and banked as it contains embryonic stem cells that can be used for the treatment of various genetic and hematopoietic diseases.

Embryonic stem cells are pluoripotent cells that can differentiate into a wide range of cells with specific properties. For example, a hematopoietic stem cell of embryo can produce different types of blood cells (WBCs, RBCs, and platelets) and a mesenchymal stromal stem cell of embryo can produce cartilage, bones, and other kinds of tissue.

Thus, the correct answer is option). 'creation of a personalized cell.'

The answer is B

Explanation:

Creation of a personalized cell replacement therapy for the donor

the right is separation by density .

take the blood which is a good example of a heterogeneous mixture.

blood is a vital liquid in our body, which transports oxygen from the air to our lungs so we can breathe. it is also used to eject wastes, such as carbon dioxide, to bring cells and molecules of the immune system to the tissues, and to spread hormones throughout the body. it corresponds to plasma, red blood cells, white blood cells, platelets and hemoglobins combined.

in medical tests centrifugal force is used to separate the different components of the blood.

in general, the centrifugation will allow to separate and analyze the different components of the blood, to know if the rate of white blood cells in the blood of a patient, for example, is normal, and therefore to know if his system immune is integrity.

under the action of centrifugal force, the solid components in the blood are drawn to the bottom of the tube in which the blood is contained. the centrifugal force then acts as an accelerated settling. it separates plasma from red blood cells and white blood cells.
