The ossa coxae and the sacrum make up the
a. pelvis
b. cranium
c. foot
d. spine

The correct answer is A. Pelvis

Explanation:

The ossa coxae, more commonly known as the hip or pelvic bone is one of the main bones in the pelvis which is joined to the sacrum and coccyx. Besides this, the ossa coxae connect the legs or posterior limbs to the spine and therefore it is an important bone for vertebrates placed at both sides of the pelvis. On the other hand, the sacrum is a triangular small bone that is placed int eh middle of the ossa coxae connectin the last vertebras. This along with the ossa coxae and coccyx form the pelvis (set of bones between the spine and limbs). Thus, according to this, the ossa coxae and the sacrum make up the pelvis.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
