Why does range of motion need to be measured separately for each joint? a. the average ranges of motion of joints are not known. b. each joint has a different range of motion. c. range of motion can change rapidly in a joint. d. none of the above select the best answer from the choices provided. a b c d

B. Each joint has a different range of motion.

Explanation:

The range of motion for each joint needs to be measured separately as each joint has a different range of motion depending on the type and placement of the joint, for instance ball and socket joints have more movement than a hinge joint.

also, observe the joints that connect your head with your body and the joint that connect your arm with your palm. The joint that connect your head and your body allow a 360 degree movement which is why you can spin your head around while the joint that connect your palm and your arm only allow 180 degree movement.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
