without brain there would be no reflex. Spinal cord is just a carrier through neurons..it's the brain which signals to pull back the hand from a hot kettle...not any other organs.

Asteroids are small, irregular lumps of rock that move in orbits around the Sun. Most asteroids lie in a vast ring between the orbits of Mars and Jupiter. This is called asteroid belt that holds millions of asteroids. Asteroids can be classified into two broad groups based on their composition and location-carbon rich asteroids dominate the outer part of asteroid belt whereas metal rich asteroids dominate the inner part of belt.
