It is a level 3 armoured door with a multilock system than can be opened through a chip coded key, a remote control system, your fingerprint and you can arm or disarm your home alarm system with the door remote control. When the door is closed an impact sensor locks the multilock system.
Some Unusual Forms of Reproduction in Bacteria: There are groups of bacteria that use unusual forms or patterns of cell division to reproduce. Some of these bacteria grow to more than twice their starting cell size and then use multiple divisions to produce multiple offspring cells. Some other bacterial lineages reproduce by budding. Still others form internal offspring that develop within the cytoplasm of a larger mother cell.
Bacteria divide by binary fission which simply means that one cell splits in two. As a separate matter, there is a process called conjugation for transfer of genetic information that is completely different than binary fission. The bacterial organism would then start to divide and multiply. Some bacteria can form spores when it cannot survive very well (such as in freezing temperature) and then take off the spore barrier when multiplication and feeding conditions are better.
