Answer:
Eukaryote cells have a membrane-bound nucleus and prokaryotic cells do not
Explanation:
Answer:
Stem cell is taken either from bone marrow or from the blood directly
Explanation:
Stem cells are derived from two locations primarily a) Bone Marrow and b) Blood
The first step in this process is to remove the stem cell from its parent location and it is done in the following ways –
A) For deriving stem cell from blood – A drug with growth factor s is injected. Here no anesthesia is given to the patient. The growth factors leads to the movement of stem cells from bone marrow into the bloods. Blood with stem cells is taken out from the veins and filtered through the apheresis machine.
B) From Bone marrow – Bone marrow is removed from the pelvic bone through a needle and prepared for transplantation.
Answer:
Explanation:
Why does your heart have to pump your blood to your lungs BEFORE it can pump it to the rest of the body?
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
what is responsible for pumping blood to the lungs?
The oxygen-poor blood fills the right atrium and then flows to the right ventricle, where it is pumped to the lungs through the pulmonary arteries. The lungs refresh the blood with a new supply of oxygen, which comes from the air that you breathe in.
Answer:
tracheae
instead of lungs, insects breathe with a network of tiny tubes called tracheae
