The last part of the metamorphosis of a tadpole to an adult frog results in the disappearance of the tail. This stage of development most likely occurs by (A) cells of the tail dying and the nutrients being absorbed and reused by the body (B) shedding of the tail so energy is not spent on maintenance of an unneeded part (C) bilateral division of the tail and fusion with the developing hind limbs (D) individual cells of the tail migrating to the developing gonads
