Hm Well, Hematopoiesis is defined as the process of blood cell production, multiplication and specialization in the bone marrow.
Answer:
The correct option is C: antigen-binding sites
Explanation:
The antibody is shaped much like the letter Y in the English alphabet. It has two antigen binding sites that are identical in nature. The specificity of these sites is determined by the amino acid sequence that makes it up. Antibodies are complementary to these antigen binding sites, and the antibodies have an incredible ability to recognize a great variety of antigens.
Hope that answers the question, have a great day!
Answer:
The correct answer will be options A, B and E.
Explanation:
Red blood cells or RBC or erythrocytes are the cells present in the connective tissue which forms the blood. RBC perform various functions in the body but the primary function is the transport of the gases in the body.
The RBC are continuously formed in the bone marrow region of the bone form the hemopoietic stem cell found in the bone marrow. These cells produce a large amount of RBC that is about 2 million cells per second in a healthy adult.
When RBC are formed posses nucleus but when mature, they lack nucleus that is genetic material and organelles like mitochondria so, they are not able to divide.
These RBC contain haemoglobin in their cytoplasm which shows high affinity to bind oxygen and low affinity to bind carbon dioxide to the iron group of haemoglobin.
Thus, options A, B and E are the correct answer.
