Answer: Osteoblasts and osteoclasts are both types of bone cells.
Explanation:
Bone is a major component of the skeletal system which is made up of highly vascular living structures that are continuously being remodelled. This is brought about by the bone cells which includes the osteoblasts and osteoclasts.
--> OSTEOBLASTS: these are the bone-forming cells that secrete collagen and other constituents of bone tissue. They are present in the center of ossification of immature bone.
--> OSTEOCLASTS: Their function is resorption of bone to maintain the optimum shape. This takes place at bone surfaces.
The balance of osteoblast and osteoclasts activity maintains normal bone structure and functions.
These are the options to choose from:
eat more meat and beans than vegetables
eat fewer servings as your activity increases
consume every food group at every meal
consume more calories as your activity increases
The correct answer is consume more calories as your activity increases.

By increasing the amount of energy burned through physical activity, you'll have to eat more calories to meet heightened needs and can eat discretionary calories.
