9. How will working out regularly at a level of intensity that maintains your body's maximum heart rate impact your body and fitness level?

i believe it is true.        

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.

i would definitly say b : )
