Exercise is vital part of astronauts’ daily routine. But despite having exercise regularly, they will still feel bone weakness after long expedition in space. Why do you think this happens?
Why do you think that astronauts are often faced with decreased bone mass after returning from periods of prolonged weightlessness?
You are Jeremy’s Biology professor, and he ask you about taking steps to “bulk up”. What would your response be, and what other things could you suggest to him to keep his bones healthy while improving his muscle strength?.

- We all get tired sometimes, especially if we have been doing a lot of physical activity like these hikers. But for Jasmin, a 34-year-old former high school track star who is now a recreational runner, her tiredness was going far beyond what she thought should be normal for someone who is generally in good physical shape. She was experiencing extreme fatigue after her runs, as well as muscle cramping, spasms, and an unusual sense of heaviness in her legs. At first, she chalked it up to getting older, but her exhaustion and longer run for more than a few minutes at a time. She also began to experience other unusual symptoms, such as blurry vision and vomiting for no apparent reason. What are mitochondria?
