No. The Human Spine does not Grow Back.

No, raccoons do not have the ability to regenerate their tails. Once a raccoon loses its tail, it will not grow back.
The human body does not regenerate organs once they've been removed. If it could, amputees could just grow another limb. Barring parts of the liver, we as humans cannot regenerate, sadly we are stuck this way. Who knows, maybe we will evolve one day?
No, kidneys do not grow back or reproduce! If the cut is not too severe, it can heal. If the cut is severe, the kidney may not recover in which case it will have to be removed.
no. All you'll get is a scar.
No. A leopard is able to grow back lost skin or tissue, but if a leopard loses a limb, it will not grow back.
Yes, a Gecko's tail will grow back over time.
Yes, you can cut rhododendrons to the ground and they will likely grow back, as they have the ability to regenerate from their roots.
No, if you were to eat your finger, it would not grow back. Human fingers do not regenerate like the limbs of some animals. It is important to seek medical attention if you have injured yourself in such a way.
No, do you really think if people could grow back limbs, there would be people who are missing limbs? Like someone in a wheelchair with missing legs? There are some animals (not mammals) that can grow back limbs though.
