(a) Anemia
(b) Leukemia
(c) Thrombocytosis
(d) Hemophilia
Correct answer: (a)
Explanation: Anemia is a condition in which the body does not produce enough red blood cells. This can lead to fatigue, shortness of breath, and pale skin.
9. What is the name of the condition in which the body produces too many platelets?
(a) Thrombocytosis
(b) Leukemia
(c) Anemia
(d) Hemophilia
Correct answer: (a)
Explanation: Thrombocytosis is a condition in which the body produces too many platelets. Platelets are blood cells that help blood clot. When there are too many platelets, they can form blood clots that block blood vessels and lead to serious health problems.
