If a starfish sustains damage to a limb, it often grows a new one. If a human adult sustains damage to his or her spinal cord, mobility is often impaired. If a gecko loses its tail, it may grow a new one. Which type of cell is less likely to go through the
cell cycle after being damaged starfish limb, human spinal cord, or gecko tail? Support your answer

The Human spinal cord. The Spinal cord, if fractured or broken, would take a long time to heal and regenerate (if at all, it barely regenerates, leaving it impaired), while the starfish and gecko can just regrow those parts.

I hope this helps!

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

3. energy generation

4. lower carbon footprint
