As mentioned, materials that are sorted and can be recycled are either placed into bins or baled. These are then sent to factories where the next step happens. For example, your paper might be made into toilet paper or paper for a printer. Plastics can be made into other plastic things, such as bottles.

Answer:
B) Is the story believable?
Explanation:
All of them can be used in a realistic fiction (using all of them may make a better story) but I think the only one that is absolutely necessary is B, making the story realistic.
A realistic fiction story is a story written about events that did not happened but may as well have had happened, so the key into writing a realistic fiction story is the capability of the writer to make his or her characters, and the situations around them, as plausible as possible.
As I said, all of the choices can be used into the story writting, so, even if the second one is the only one absolutely necessary, all the others have the power to<u> make your story a better and more interesting one.</u>

1. Samples of a microbial colony obtained from the natural environment are not pure culture. They are mixed cultures because the environment consists of an array of microorganisms and not one specific organism. A sample obtained from the natural environment such as water or soil may contain several species of microbes that need to be further isolated to obtain a pure culture.
2. Isolation streak plate technique involves the dilution of the sample several folds and then streaking a small amount using a sterile inoculation loop on an agar plate in a zig-zag manner. This is done to obtain a pure culture of bacteria from a mixed population by separating the microprocessor. When the sample is diluted into a small concentration and is streaked onto agar placed, widely spaced, discrete colonies of bacteria can be observed. These isolated colonies can be further cultured to obtain pure cultures by picking and re-streaking them on fresh agar plates.
3. A microbial colony is considered a pure culture because it consists of single species. A single species of bacteria cluster and form an isolated colony on an agar plate which can be further plated on fresh medium.
3-1 - If your agar plate shows discrete uncluttered colonies then you have obtained an isolated colony. The following picture might help you to understand.
3-2. If you subculture isolated microbes into a sterile nutrient broth without any contamination, it will still be considered pure culture because it is single isolated species in a sterile aseptic environment of the nutrient broth.
3.3. A pure culture can become a mixed culture due to contamination. This could be caused by airborne bacteria if your conditions are not aseptic. Contamination is possible if the work area is not clean and sterile or if the glassware is not sterile. The contamination can transform your pure culture into a mixed culture and is hence problematic. So, it is very important to maintain a sterile and aseptic environment, glassware, and instruments.

Answer:
Overwhelmingly rural, North Carolinian's were isolated from the world around them, as well as each other, by geographical barriers, limited means of transportation, and their own independent spirit. However "backward" and "indolent," most Tar Heels had a more discerning, if not more favorable, view of their lifestyle and themselves. Times were hard; there is no doubt. Days were long and rewards were slight. Yet an increasing number of Carolinian had succeeded in purchasing their own farms. And, as the Fayetteville Observer, in 1837, proudly pointed out: "The great mass of our population is composed of people who cultivate their own soil, owe no debt, and live within their means. It is true we have no overgrown fortunes, but it is also true that we have few beggars."
