How many bacteria in the world?
there is actually millions and countless bacteria in the world
The number of bacteria increased by 280 overnight if there were 30000 bacteria yesterday how many bacteria were present this morning?
30280 30000 + 280
Air has 4000 bacteria per cubic meterThere are 120000 bacteria in a room that is 3 m long by 4 m wide What is the height of the room?
Divide the amount of bacteria in the room by the amount of bacteria per cubic meter to discover how many cubic meters the room is: 120,000/4,000 =30 cubic meters Then you set the rest up as an algebraic equation: Volume=LxWxH V= 3 x 4 xH 30=12 x H Divide both sides by 12 in order to isolate Height 2.5=H This means that the height of the room is 2.5 meters.
How does bacteria replicate?
"Unlike multicellular organisms, increases in the size of bacteria (cell growth) and their reproduction by cell division are tightly linked in unicellular organisms. Bacteria grow to a fixed size and then reproduce through binary fission, a form of asexual reproduction.[96] Under optimal conditions, bacteria can grow and divide extremely rapidly, and bacterial populations can double as quickly as every 9.8 minutes.[97] In cell division, two identical clone daughter cells are produced. Some bacteria, while still reproducing asexually, form more complex reproductive structures that help disperse the newly formed daughter cells. Examples include fruiting body formation by Myxobacteria and aerial hyphae formation by Streptomyces, or budding. Budding involves a cell forming a protrusion that breaks away and produces a daughter cell."-Wikipedia
What two parts of a bacterium determine its shape?
cell wall and DNA because bacteria don't have a cytoskeleton
