The arteries that branch from the aorta and provide blood to the heart muscle itself are arteries. a. pulmonary b. systemic c. coronary d. femoral

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
