Answer:
A debate is a structured argument. Two sides speak alternately for and against a particular contention usually based on a topical issue. Unlike the arguments you might have with your family or friends however, each person is allocated a time they are allowed to speak for and any interjections are carefully controlled.

Answer:
self-administered survey
Explanation:
Jackie is doing a study on the number of hours spent watching TV and how this affects family cohesion. She decides to mail a questionnaire to randomly selected households in her state. This is an example of <u>self-administered survey</u>. A self-administered survey is a survey that is done or designed in such a way that the researcher will not interfere with the respondents. In this method the respondents complete the survey on their own with no agent to guide or interfere in the process. While this method is relatively cheap, the respondents feel more at ease, there is a higher requirement of respondents because due to the absence of monitoring or guidance there is usually increased error in questionnaires.
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.
