Cameron learned that carrying more weight around the middle could put you at risk for certain conditions. She wants to use a body composition method to determine her body composition and also wants to know about weight distribution. Which method would be BEST to determine all she needs to know? A. body mass index because it compares you to others B. waist to hip ratio because it is not specific but helps determine weight distribution C. an MRI because it uses high speed electrical signals and body mass to determine body composition D. skin fold measurement because the calipers give you an exact calculation of how much fat is located in each area of the body Please select the best answer from the choices provided. A B C D

Muscles in the body us with a lot of things for example, if i wanted to lift a heavy box and had no muscle i would just collapse where i was because of the fact muscles hold us together. overall they are 650 muscle in the human body, all of them have different purposes and ways to keep us together. there are three types of muscle in the body skeletal, smooth, and cardiac muscle. skeletal muscle are attached to the bone and with movement. smooth muscle, this is found in the wall of our organs, such as our stomach, this muscle with movement   as well, without this muscle, we would only be allowed to eat small amounts. the cardiac muscle is the heart muscle and probably the most important one. these are only found in the walls of the heart and the heart pump blood to the other parts of your body. we have two different types of muscle fibers, slow twitch and fast twitch. slow twitch muscles enable long-endurance feats such as distance running. fast twitch fatigue faster but are used in powerful bursts of movements like sprinting. there are three different types of muscle contractions concentric, eccentric, isometric. concentric contraction causes muscles to shorten, thereby generating force.   eccentric contractions cause muscles to elongate in response to a greater opposing force. isometric contractions generate force without changing the length of the muscle.: //athleticquickness.com/muscle-contraction-types-part-1/

Ican only answer your first question, a machine is like a human body because it's a little similar. they both almost work like the same.
