- A.
Pernicious anemia
- B.
Iron-deficiency anemia
- C.
Aplastic anemia
- D.
Hemolytic anemia
- E.
Thalassemia
Correct Answer
D. Hemolytic anemiaExplanation
Hemolytic anemia is characterized by a reduction in red blood cells due to excessive destruction of these cells. This condition can be caused by various factors such as autoimmune disorders, infections, certain medications, or inherited conditions. The destruction of red blood cells leads to a decrease in the oxygen-carrying capacity of the blood, resulting in symptoms such as fatigue, pale skin, and shortness of breath. Treatment for hemolytic anemia may involve addressing the underlying cause, medications to suppress the immune system, blood transfusions, or, in severe cases, a bone marrow transplant.Rate this question:

Protein threads that form the basis of a clot
- A.
Fibrinogen
- B.
Globulin
- C.
Hemoglobin
- D.
Thrombin
- E.
Fibrin
Correct Answer
E. FibrinExplanation
Fibrin is the correct answer because it is the protein thread that forms the basis of a clot. When there is an injury or damage to a blood vessel, fibrinogen, a soluble protein, is converted into fibrin by an enzyme called thrombin. Fibrin then forms a mesh-like structure that traps platelets and red blood cells, leading to the formation of a blood clot. This clot helps to stop bleeding and promotes wound healing.Rate this question:
