ANSWER: A.Mature RBCs
SOLUTION :Ribosomes are the organelles which are responsible for protein synthesis. They are devoid of DNA.

ANSWER:A.Defence mechanism
SOLUTION:Globulins contained in human blood plasma are primarily involved in. Defence mechanisms of the body.

ANSWER :A.Besophills
SOLUTION:Basophils of white blood cells are connected with the release of histamine and the natural anticoagulant heparin. Basophils appear in many specific kinds of inflammatory reactions, particularly those that cause allergic symptoms. Basophils contain anticoagulant heparin, which prevents blood from clotting too quickly.

ANSWER: D.Damaged tissue
SOLUTION: During blood coagulation, thromboplastin is released by platelets and damaged blood vessels and surrounding tissues.

ANSWER: A.Haemoglobin
SOLUTION:Red blood cells contain a red coloured pigment called haemoglobin. Haemoglobin gives red colour to the blood. It also helps in transport of oxygen and carbon dioxide.

ANSWER: B.Heme
SOLUTION: Haemoglobin: RBCs/erythrocytes play an important role in the transport of oxygen to various tissues. It is mainly due to the presence of an iron-containing, red-colored pigment called haemoglobin.

ANSWER:B.Monocytes
SOLUTION:Monocytes are the largest type of WBCs while lymphocytes are smallest.

ANSWER: A.Lymphocytes
SOLUTION: The process of reabsorbing useful substances from the filtrate back into the blood is called tubular reabsorption. It’s a selective process that occurs primarily in the proximal tubule of the nephron. Tubular reabsorption reclaims about 99% of the filtered water and many useful solutes, such as glucose, amino acids, and electrolytes. This process is critical in maintaining the body’s electrolyte and fluid balance.

ANSWER:B.Basic
SOLUTION: Plasma, also known as blood plasma, appears light-yellowish or straw-colored. It serves as the liquid base for whole blood. Whole blood minus erythrocytes (RBCs), leukocytes (WBCs), and thrombocytes (platelets) make up the plasma.

ANSWER: D.Fibrin
SOLUTION: A clot of blood contains. Prothrombin. Fibrinogen. Fibrin. Thrombin Blood protiens are incapable of blood clotting inside the blood vessels but form blood clot at the injury. How is it possible? Explain clotting of blood.
