Lisa's grandmother was recently diagnosed with heart disease. her doctor told her she should have some body composition testing done to determine if her
body composition is putting her at a greater risk of this condition. she is on a tight budget. which of the following is the easiest and least expensive test for her to start with?
a. weight circumference
b. mri
c. hydrostatic weighing
d. none of the above

I believe the answer is: A.weight circumference

The fat percentage in our body could increase our chance of developing heart attack (more fat resulted in higher risk of heart attack). Checking a weight circumference on our waist is usually a good indicator to measure our body fat percentage without suing laboratory equipment.

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.
