Answer:
Letter C is the correct answer.
Explanation:
No Child Left Behind (or NCLB) was a law for K-12 Education in the U.S. between 2002 and 2015 (it was replaced by Every Student Succeeds Act that year) and the main issue was how children were learning at school.
Options A, B, and D are related to the academic status of the professor, since A talks about tests taken by teachers; letter B refers to state qualifications in the area teachers have in charge; letter D also talks about how professors can prove they are able to teach their subjects: all these options are strictly related to how children can learn and how exams and certifications can help teachers in this task. On the other hand, Letter C does not relate directly to students' performance in the classroom, and that is why this is the correct answer.
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.

Projects take a longer time with poor end products and, in worse situations, total project failure because of inconsistency in the tasks to be performed and order to perform that tasks.
<h3>What is a project task?</h3>
Basically, the task means the single unit of work that needs to be accomplished within a project while a project is the entire series of tasks that need to be completed together to accomplish a single outcome or goal.
In management, a project task is a work item or activity with a specific purpose related to the larger goal. It is the necessary step on the road towards project completion.
Therefore, the inconsistency of task causes projects to take a longer time with poor end products and, in worse situations, total project failure.

Answer:
B. time lags make it very difficult to judge when the policy will have an effect.
Explanation:
The main argument against using active policymaking is that time lags make it very difficult to judge when the policy will have an effect.
