Question #45b25

Answer 1

DNA

Explanation:

If all of the DNA in the cells of a human body was unraveled and laid end to end, it would stretch out to `1.20xx10^9` kilometers. The moon is about `4.0xx10^5` kilometers away from the earth, so the DNA would stretch to the moon and back 1500 times. In fact, it would stretch to the sun and back about 4 times. The sun is `1.5xx10^8` kilometers away from the earth.
