Question

anemia is more likely with increasing age because
multiple choice
the amount of red bone marrow decreases.
the amount of yellow bone marrow increases.
the leukocyte levels continually increase.

Explanation:

Red bone marrow is responsible for producing red blood cells. Anemia is a condition related to low - red - blood - cell count. As age increases, the amount of red bone marrow decreases, reducing the production of red blood cells and increasing the likelihood of anemia. Yellow bone marrow is mainly for fat storage and leukocytes are white blood cells not directly related to red - blood - cell production in this context.

Answer:

the amount of red bone marrow decreases.
