The plasmid have a "reporter gene" inside it, generally resistance to specific antibiotic. the plasmid is transformed into bacteria that don't have resistance to that specific antibiotic drug, and than the cultured on a petri-dish that contain the antibiotic drug. Only bacteria that had receive the plasmid will have resistance and grow, all the other will die.
Assume each colony started as a single bacteria in the original culture. Count the colonies you have and multiply up according to how diluted you made the culture and how much of the original culture you used.

It can be either bacterial of viral. Your doctor will do a strep test and possibly a throat culture to determine the cause. If either is positive, that means that the tonsillitis is caused by bacteria. Penicillin or another broad base antibiotic will then be prescribed. If viral, there isn't a whole lot one can do except wait it out and try to relieve symptoms.
A bacterial culture containing a single species of organisms is referred to as a pure culture. This means that there is only one type of bacteria present in that culture without any contamination from other species. Pure cultures are essential for studying specific bacterial characteristics and behavior.
Changes in the turbidity of a bacterial culture can be measured using a spectrophotometer, which quantifies the amount of light scattered by the culture at specific wavelengths. As bacterial density increases, the culture becomes more turbid, resulting in higher absorbance readings. Additionally, a nephelometer can also be used to measure turbidity by detecting scattered light at specific angles. Both methods provide an indirect assessment of bacterial growth over time.
Bacterial cells are useful in recombinant DNA technology because they can easily take up foreign DNA through a process called transformation. Once the foreign DNA is inserted into a bacterial cell, it can be replicated and amplified quickly. Bacteria are also easy to culture and manipulate in the laboratory, making them ideal for producing large quantities of recombinant proteins or DNA fragments.
Inoculating Tryptic Soy Agar slant with a pure bacterial culture ensures that any growth observed is from a single bacterial species, allowing for accurate identification and characterization. Inoculating with a mixed culture can lead to overlapping growth patterns, making it difficult to determine the morphology and characteristics of individual bacterial species present.

Recombinant vectors or Viral vectors are tools commonly used by molecular biologists to deliver genetic material into cells. This process can be performed inside a living organism (in vivo) or in cell culture (in vitro).
It's a bacterial culture.
Yes it is. The bacterial culture is the same.
