1 A unit-quantity of electricity used as a measure of the amount of electrical charge that may be obtained from a storage battery before it requires recharging. 2  Ampere-Hour Capacity -- The number of ampere-hours which can be delivered by a storage battery on a single discharge.
A: Bacteria obtain energy by either ingesting other organisms and organic compounds or by producing their own food. The bacteria that produce their own food are called autotrophs. Bacteria that must consume other organic molecules for energy are called heterotrophs.
Each daughter cell is a clone of the parent cell. When conditions are favourable such as the right temperature and nutrients are available, some bacteria like Escherichia coli can divide every 20 minutes. This means that in just 7 hours one bacterium can generate 2,097,152 bacteria.After one more hour the number of bacteria will have risen to a colossal 16,777,216.Thatâs why we can quickly become ill when pathogenic microbes invade our bodies. 1/3 Bacteria reproduce asexually by binary fission.or example it may contain a gene that makes the bacterium resistant to a certain antibiotic. Bacteria are classified into 5 groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes).
