What action removes carbon dioxide from the body

When you exhale is when carbon dioxide is removed from the body. Hope this helps! :)

which of what? i am confused

absolute strength refers to the maximum force exerted by a body irrespective of body size. relative strength on the other hand is the force exerted by a body in relation to muscle size or body weight.

so the answer is: c. absolute strength measures strength regardless of your body size, while relative strength measures strength adjusted for your weight.
