Many bacteria required special nutrient and enviornmetn for their grwoth and reproduction and they can not survive without them. These type of bacteria are more sensitive in culture process. e.g. Nesseria gonorrhoeae needs blood agar to grow rather then normal nutreint agar medium.

There is no one answer to this question as different bacteria have different sensitivity to the culture process. However, some bacteria are generally more sensitive to the culture process including those that are fastidious (require specific nutrients or growth conditions), those with delicate cell membranes, and those that are susceptible to contamination by other microorganisms. Examples of bacteria that may be more sensitive to the culture process include species of Mycobacterium and Neisseria.

How would you define pure culture sterile and contamination in the isolation and purification of bacteria?
A pure culture is defined as a population containing only a single species or strain of bacteria. Contamination means that more than one species is present in a culture that is supposed to be pure.
What do bacteria produce?
"Bacteria producing bacteria" - this is not a specific type of bacteria, as you might say a dog is a specific type of animal. All bacteria reproduce, and form new bacteria through a process usually called binary fission. In this way, each bacteria produces more new bacteria. It is not a trait of one species of bacteria.
Why did you use a young culture for flagella stain?
Young cultures are typically used for a flagella stain because they are healthier and livelier. This helps the flagella get seen easier since the bacteria are continuously moving.
How do bacteria typically reproduce?
Bacteria generally reproduce by splitting in half, a process called Mitosis. They are asexual reproducers. it is more commonly called binary fission.
What is the process called in which cultures become more and more similar to one another?
Cultural convergence

What Positive Adaptations?
Positive adaptation which is also called sensitization is a type of sensory adaptation in which we become more sensitive to stimuli that are low in magnitude. It is the process of becoming for sensitive.
What is the comparative and superlative of the word sensitive?
Comparative: more sensitive Superlative: most sensitive

What is anglicized?
Anglicization is the process of making something, particularly a word within language or culture, more English.
How could you tell the bacteria were growing in the culture?
Bacteria growing on a petri dish can have more than one bacteria growing on it, but different characteristics can be seen like cilia, motility and color. To know more specifically what those other bacteria strains are, get a sample and grow it on agar by itself.

How is mutation diagnosed?
In Microbiology, we usually identify mutated bacteria/mutants/mutated DNA by using a number of methods, such as: 1.) Positive selection - For example, we want to identify a mutant bacteria that are resistant to antibiotics, such as say, penicillin, a beta-lactam antibiotic. We plate the bacteria in a medium that contains penicillin, if the bacteria is from a pure culture known to be penicillin-sensitive then we could expect that there will be no growth, if there is growth however, we could say that bacteria is mutated and most likely contains the enzyme beta-lactamase. 2.)Negative selection - This process selects a cell that cannot perform a certain function, we ofen times use the technique of replica plating. For example, we plate a pure culture in a medium with histidine, all of these will form colonies. Next is, we transfer the colonies using a sterile velvet into two or more plates, one contains histidine, the other does not. If a colony that is present in the histidine medium is absent in the other medium, we can assume that bacteria has lost its ability to synthesize it's own histidine.
Why bacteria grows faster ion open air than in refrigerator?
The incubation time is important because however long your culture is kept in incubation affects how many colonies you will have at the end. A short incubation time will result in minor bacterial growth, whereas a longer incubation will result in more colonies, as you're giving the bacteria more time to grow. Be careful, if you leave your culture in incubation for too long, the bacteria will begin to use up all of the agar and start competing for food resources. If left even longer, this will consequently result in the death of your culture.
