Question

Why should astronauts be aware of bone loss when working in space, even for a short period of time?



A. Not enough stress is placed on the bones, making them weaker.
B. Dehydrated food from tubes weakens bones.
C. Excessive force during take-off and landing increases bone stress.
D. Not enough calcium to become available to build bones.

Answer 1

D ..not sure..

Answer 2

it's either A or C

Answer 3

i think A because in space you kinda don't need bones anymore, they're made for stability but in space you don't have weight. What the body doesn't need, it'll get rid of.

Excessive force during takeoff and landing won't make you lose bone, maybe only cracking some....

Answer 4

I think the answer is A. Because in space you experience zero g or zero gravity which for short or prolonged times cause osteoporosis, which is the deterioration of bones. When you are at zero gs you are not exercising or putting a healthy amount of weight and stress on your bones. When you dont put weight and stress on your bones they get weaker and start to deteriorate.

Answer 5

wolffes law ---sress and tension placed on a bone induces bone formation due to less gravity less tension and stress on bones....less bone stregth
