Question

what is the function of the yellow bone marrow?
store fat
produce red blood cells, platelets, and white blood cells
supply nutrients to the bones
provide strength for the bone
reduce friction and absorb shock between bones

Explanation:

Yellow bone marrow mainly consists of fat - storing cells. Red blood cells, platelets, and white blood cells are produced by red bone marrow. Nutrient supply to bones is mainly through blood vessels, not yellow bone marrow. Bone strength is provided by bone tissue itself, and reduction of friction and shock - absorption between bones are functions of cartilage and synovial fluid, not yellow bone marrow.

Answer:

store fat
