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

A) cells of the tail dying and the nutrients being absorbed and reused by the body

Explanation:

The tails of the tadpole die when metamorphosing into an adult frog through a process Called Apoptosis. Apoptosis happens when it’s necessary for the body to kill some cells for development or other factors.

The cells which are killed produces nutrients which are then used and reabsorbed back into the body system of the frog.

mammal

explanation:

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
