d) decreased ability to store iron

Answer 1

Iron requirements increase during adolescence due to the expansion of blood volume and increase in muscle mass.

Step-by-step explanation:

Iron requirements increase during adolescence because of the expansion of blood volume and increase in muscle mass. The increase in blood volume and muscle mass requires more iron to support the production of hemoglobin, which carries oxygen to the tissues. Iron is also essential for energy production and cellular respiration.
