As water molecules are polar, polar molecules dissolves in water.

Anaerobic glycolysis is the transformation of glucose to lactate when limited amounts of oxygen (O2) are available. 

Hence, Anaerobic glycolysis occurs without oxygen.

Hardware device that maps virtual to physical address. In MMU scheme, the value in the relocation register is added to every address generated by a user process at the time it is sent to memory.

->The user program deals with logical addresses; it never sees the real physical addresses
