The oval surrounding their name was meant to protect them from evil spirits in life and after death. The cartouche has become a symbol representing good luck and protection from evil. Egyptians believed that one who had their name recorded somewhere would not disappear after death. A cartouche attached to a coffin satisfied this requirement.
A single mole can construct 200 mounds over the course of a winter. (Drawing by Jenifer Rees.) Moles construct two kinds of tunnels: surface tunnels and deep tunnels, or runways. Surface tunnels are located 1 to 4 inches below the surface.
1 Although it is not possible to directly measure how many moles a substance contains, it is possible to first measure its mass and then convert that amount to moles.  A substance's molar mass is calculated by multiplying its relative atomic mass by the molar mass constant (1 g/mol).
