Question

question 2
why is exercise an important part of living aboard the international space station? is exercise more important for health on the iss than on earth? explain.

Explanation:

In the ISS, microgravity causes muscle atrophy and bone density loss as the body doesn't need to work against gravity as on Earth. Exercise counteracts these effects by stimulating muscles and bones. On Earth, gravity naturally helps maintain muscle and bone health, so exercise on ISS is more critical to prevent rapid physiological decline.

Answer:

Exercise is important on the ISS because microgravity causes muscle atrophy and bone density loss; exercise is more important on the ISS than on Earth as Earth’s gravity naturally supports muscle/bone health, while ISS’s microgravity requires exercise to prevent rapid physiological decline.
