Answer 1

some Bacteria have dormant , protective states that are specifically designed to survive in very harsh environment, they are called spores

but generally bacteria are just way less complicated then other organisms, so if they get frozen, it sometimes does not cause as much damage and they can survive it and repiair the damage
