The answer is <span>B both are unicellular.
E. coli and paramecium are both unicellular. And that is their only common characteristic. E. coli is a prokaryotic unicellular organism while paramecium is a eukaryotic unicellular organism. So, paramecium has nucleus and E.coli has a nucleoid. Neither of them produce essential vitamins. Contractive vacuoles are present only in paramecium.</span>
Answer: Collaterals
Explanation:
According to the given question, the collateral is one of the side branch in the blood vessel and it is also known as the subordinate part in the vessel.
The main function of the collateral is that it basically developing the shunt blood circulation at the block vein or artery areas and plays an important role at the time of surgeries.
An axon is basically branch producing the branches at the similar time for the communication purpose is know as the collateral. Therefore, Collaterals is the correct answer.
Coronary
arteries supply blood to the heart muscle, The left one, arises from the aorta and
feeds blood to the left side of the heart and the right one supplies blood to
the right ventricle, the right atrium, and the SA (sinoatrial) and AV
(atrioventricular) nodes, which regulate the heart rhythm.
Blockage
in this vessel result in
<span>reducing
the flow of oxygen and nutrients to the heart muscle and that can lead to a
heart attack. Atherosclerosis and arteriosclerosis are the most common causes
of heart disease.</span>
Allogeneic hematopoietic cell transplant is procedure in which a patient receives healthy blood-forming cells (stem cells) from a donor to replace their own stem cells that have been destroyed by treatment with radiation or high doses of chemotherapy.
An allogeneic hematopoietic cell transplant uses a donor's bone marrow or blood. The donor is usually a relative of the patient, although unrelated donors or umbilical cord blood are sometimes used.
Allogeneic stem cell transplantation involves transferring the stem cells from a healthy person (the donor) to the patient's body after high-intensity chemotherapy or radiation. The donated stem cells can come from either a related or an unrelated donor.
