Which condition relates to low red blood cell counts or low hemoglobin?

• A. Anemia
• B. Aerobic metabolism
• C. Amphetamines
• D. Adipose tissue

Answer: (A)

Low red blood cell counts or low hemoglobin define anemia. Red blood cells and hemoglobin are responsible for carrying oxygen from the lungs to tissues throughout the body, so when their numbers are reduced or the hemoglobin content is low, the blood can’t deliver oxygen as effectively. That reduced oxygen delivery leads to symptoms like fatigue, weakness, and shortness of breath, which is why this condition is described in terms of RBC counts or hemoglobin levels. The other options refer to processes or tissues rather than a hematologic disorder: aerobic metabolism is about how cells generate energy with oxygen, amphetamines are stimulant drugs, and adipose tissue is body fat.
