A. copper B. iron C. zinc D. nitrogen 2 The inherited disease sickle cell anemia occurs because of an abnormally shaped protein taking the place of one of the A. alpha B. beta chains. C. gammaExplanation / Answer
Answers:
6. Option B
Antibodies are the set of proteins which are found in our blood and are responsible for the clearance of the antigens by attacking them. They are prepared by a set of cells called B cells and are having a lineage called memory cells which helps in easy elimination o the further antigen attacks.
7. Option B
The process of formation of the different formed elements of the blood that is the different types of cells of the blood is called as haemopioesis. It initially in the fetus used to be the yolk sac, followed by the liver and in later stages gets replaced with the bone marrow.
8. Option B
Haematocrit value or the packed cell volume is the volume of the red blood cells to that of the whole blood. Upon sedimentation, the average values calculated came out to be approximately 45 percent of the red blood cells to that of the 55ml of the plasma
9. Option A
Haematocrit value or the packed cell volume is the volume of the red blood cells to that of the whole blood. Upon sedimentation, the average values calculated came out to be approximately 45 percent of the red blood cells to that of the 55ml of the plasma. However in females, the value gets little lower as the females undergoes menstruation.
10. Option A
Hemoglobin is a protein made up of two alpha chains and two beta chains in adults,. They have a binding efficiency for different gases like oxygen, carbon dioxide and also carbon monoxide. This is due to the fact that humans have a high surface area ratio and merely diffusion of the gases will be sufficient to suffice the needs of the entire body parts. Hence the presence of the pigment is required which is hemoglobin and is present inside the Red blood cells. For that reason only, human red blood cells are not having any nucleus and other cell organelles.
11. Option B
The central metal ion in the hemoglobin molecule is iron which has a strong binding affinity for the oxygen molecule. Due to this at a time, a hemoglobin molecule can bind up to four oxygen atoms.
12. Option B
In the genetically inherited disease; sickle cell anemia the amino acid at the sixth position of the beta chain of haemoglobin which usually be valine; gets replace with a different amino acid that is glutamic acid which changes the shape of the hemoglobin protein molecule to sickle shaped; due to which the oxygen carrying efficiency of the molecule decreases
