Answer:
The stem cells possess two cardinal characteristics, that is, self-renewal and differentiation. The examples are embryonic stem cells and hematopoietic stem cells. The genetically determined immunodeficiency in a person is generally a result of the defective gene in the hematopoietic stem cells that produce red blood cells, white blood cells, and other components of blood.
The examples of genetically determined immunodeficiency diseases are SCID, X-linked Agammaglobulinemia, and others. The individual suffering from genetically determined immunodeficiency exhibits a defective gene in hematopoietic stem cells. There are two methods of treatment, that is, stem cell therapy and gene therapy.
The procedure of stem cell transplantation generally comprises HLA matching, in which the main step is to prevent graft rejection. It is succeeded by harvesting of hematopoietic stem cells from the HLA matched donor. The step of conditioning is performed to eradicate the recipient HSCs by radiotherapy and chemotherapy succeeded by the transfer of harvested donor HSCs to the patient or the recipient.
A person cannot receive his own stem cells as his or her each and every cell is defective in that specific gene accountable for the disease.
Answer:
The heart valves
Explanation:
The heart valves prevent blood from flowing in the wrong direction in the heart. The valves are held in the proper place because of the chordae tendinae.
Answer:
i would write about a well economically developed country like " USA, China, Japan or Germany" Vs a badly developed country like "Fiji , Peru , South Africa" its easy to research these places :)
Explanation:
good luck champ
Sensory neurons
Dmitry holds his hand close to a fire. His sensory neurons allow him to feel the heat, while his motor neurons allow him to move his hand away from the fire.
The Sensory neurons are the nerve cells that receive information from the sensory receptors and transmit the information from the sensory receptors to the brain through the spinal cord. In the question given, Dmitry was able to feel the heat when he held his hand close to the fire because the sensory receptors in the skin transmits information through the sensory neuron from the environment to the central nervous system.
If the disease was cause by the dominant allele, every person with said gene would be affected with the disease. if the genetic allele is recessive, both parents can be carriers (hetero) without being affected. that makes it easier for the genes to keep being passed on.
hope this helps!
