Answer:
Explanation:
we have three strains.
the first is the wild type which has tryptophan mRNA which gets degraded rapidly and tryptophan synthase which is stable. therefore, in the presence of tryptophan, no new mRNA is formed and whatever tryptophan synthase was present would be diluted out as cells continue to divide.
Strain A has stable mRNA and stable tryptophan synthase. so since the mRNA is present, new enzyme will continue to form from it. However, since no new mRNA is formed, the enzyme activity will get diluted as cells divide, but at a much slower rate than the wild type.
in Strain B , synthase is rapidly degraded and no new mRNA is formed. so the tryptophan synthase activity would decrease drastically.
Answer:
The correct answer will be- complex system.
Explanation:
A scientific investigation is performed to understand and explain the natural phenomenon using the scientific method.
An investigation is performed in one of the three ways: descriptive, comparative and experimental.
In the descriptive investigation, the investigation provides a descriptive account of any "complex system" by observing it when no prior knowledge is known. Therefore this method does not include the formation of a hypothesis.
Thus, complex system is the correct answer.
Answer:
As quantitative data collection methods are often based on mathematical calculations, the data obtained that way is usually seen as more objective and reliable than qualitative. Some of the most common quantitative data collection techniques include surveys and questionnaires (with closed-ended questions).
