Question

Children tend to have more __________ bone marrow, most of which becomes __________ bone marrow as they become adults.

a.) calcified; fatty
b.) fatty; calcified
c.) yellow; red
d.) red; yellow

Answer 1

Children have more red bone marrow for blood cell production, which turns into fat-storing yellow bone marrow as they mature.

Step-by-step explanation:

Children tend to have more red bone marrow, most of which becomes yellow bone marrow as they become adults. Red bone marrow is crucial for hematopoiesis, the process for the production of blood cells, including erythrocytes (red blood cells), leukocytes (white blood cells), and platelets.

Yellow bone marrow, on the other hand, primarily contains adipose tissue which stores energy in the form of triglycerides within adipocytes. As children grow, their bone marrow transitions from this blood cell-producing red marrow to the fat-storing yellow marrow.
