Answer:
A) The CRP pays farmers not to grow crops on land that is not very well suited for crop production.
Explanation:
Conservation Reserve Programme (CRP) which was created by the Food Security Act of 1985, in the United States establishes, pays a yearly rental payment to the farmers, so that the farmers would not grow crops on the land that is not very well suited for crop production.
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.

This form of circular inquiry that asks questions and questions answers is called <u>"sociological thinking".</u>
It is regularly contended that sociological thinking is only a branch out of commonsense. Individuals connect it with investigating the undeniable and giving round thinking that never appear to have an experimental method for approval.
Sociological thinking endeavors to see the general public not as a gathering of disconnected people or separate organizations, yet in general.
Sociological thinking enables difficulties to the assumed realistic and desires a more radical and inciting way to deal with the social certainties.
