How long will a 1 mm long colony of bacteria be in 1 hour if it triples in length every 15 minutes?
This question takes a little reasoning power. You have to work it through.First, we establish that there are FOUR fifteen minute periods in every hour.So in in fifteen minutes, it will triple from 1 to 3 MM long.In another fifteen minutes, it will triple again, from 3 to 9 mm.After forty five minutes it goes again, to 27 mmAnd finally, at the end of the hour, it triples from 27 mm to 81 mm.
What is mean by cfu?
It is the concentration of bacteria in any solution.CFU stands for Colony Forming Units. Colony forming unit is a form of measuring bacteria grown on a streak plate.
What are colony stimulating factors?
Certain drugs used in treating cancer reduce the body's ability to fight infections. Although colony stimulating factors help restore the body's natural defenses, the process takes time. Getting prompt treatment for infections is important.
What are examples of social behavior?
bees in a colony lions humans termites ant colony
The first successful English colony in America was established in 1492 1620 1607 or 1630?
The first successful English colony in America was established in 1607
What is a bacteria colony?
a bacteria colony is the same as a colony that is found in bacteria and fungus begins to form once you've seen a colony.
If bacteria in a colony are unable to perform conjugation how would this hurt the colony's chance for survival?
The colony would have less genetic variation. The Bacteria in the colony would be too genetically similar
How do scientists study how bacteria are affected by antibiotics?
Laboratory scientists culture a bacterium (one single bacteria) so the bacteria grows to a colony. Scientists create many specimens of colonies for each bacteria. Then they can expose each colony to a different antibiotic medication or new antibiotic to see how the bacteria react to it. They look for sensitivity--meaning, any reaction in the growth of the bacterial colony. The growth may have no change (no sensitivity), slow down, or stop. But even better, ingredients in antibiotics need to disrupt the way bacteria use nutrients, so scientists look to see if the bacteria die when exposed to that specific antibiotic.Different groups or families of antibiotics work best on certain bacteria. At the same time, certain bacteria favor conditions only in certain areas of the body. So the bacteria for a skin infection is different from the bacteria that infects the urinary tract, for example.
What is a mass of bacteria that forms?
A mass of bacteria is a colony.

The bacteria in colony are unable to perform transduction. how would this hurt the bacterial colony's chance for survival?
The bacteria would generally be more similar
What is a colony in microbiology?
A colony is a group of identical bacteria (clones) which grow together into a visible cluster. Generally, a colony is grown on an nutrient agar plate (on a petri dish with bacteria food in it) such that it is large enough to see the bacteria. An additional type of colony is a "microcolony" which is a term used for a group of the same bacteria which grown in the dirt.
What is bacterial colony?
A group or cluster of bacteria derived from one common bacteria.
What are groups of bacteria living together in a close knit group known as?
A close knit group of bacteria is known as a colony. All bacteria cells in a colony are genetically identical because they grew from a the same bacteria cell.
He bacteria in a colony are unable to perform transduction. How would this hurt the bacterial colony's chance for survival?
the bacteria would be more genetically similar.
Can colony morphology help to determine the identity of bacteria?
to know the amount of bacteria present
Are the bacteria from one colony geneticaly identical?
Not always. Sometimes, during protein synthesis, the DNA of bacteria makes a mistake and copies the wrong protein causing a defect. This can cause the bacteria in the same colony to be slightly different. Also, bacteria can evolve very quickly, so this can also cause the bacteria in one colony to be slightly different.
