Q:Swimming benefits bones more than weight-bearing exercises.
Q:Swimming benefits bones more than weight-bearing exercises.
The correct answer is: • False

The correct answer is: C The amount of bone present in a given amount of the skeleton
Explanation:
Bone mass (bone density) is determined by the amount of bone present in the skeletal structure. Generally, the higher the bone density, the stronger the bones.
Children ages 9-18 need the most calcium -- about 1,300 mg each day -- because their bones are growing rapidly. By the end of this period, youths will have established almost 90% of their adult bone mass.
Q:About 20% of people with osteoporosis are _______________.
Q:Osteoporosis can cause bones to resemble _______________.
The correct answer is: • A sponge
Explanation:
Osteoporosis literally leads to abnormally porous bone that is compressible, like a sponge as opposed to a brick. This is caused by a decrease in the density of bone in addition to its decreasing strength and increasing fragility.
Q:More than 99% of the body's calcium is contained in bones and teeth.
The correct answer is: C Both of the above and more
