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.
Bacterial reproduction. Bacteria usually reproduce by a simple form of asexual reproduction called binary fission (splitting into two). This is different from the normal process of cell division in higher plants and animals which starts with mitosis. Bacteria do not have the same sort of chromosomes as these organisms so it is not necessary to have the mechanisms (mitosis) to separate them into groups.
