Answer:
The steps that can be seen in this story are observation and the questioning phase, which can also be called elaboration of the problem.
Explanation:
The scientific method is a set of phases that are able to guide researchers to the creation of scientific knowledge, through an experiment. This method is essential for conducting scientific research, allowing an experiment to be managed in a way that promotes answers to scientists' questions. The scientific method presents the phases called observation, questioning (or elaboration of the problem), elaboration of hypotheses, experimentation, analysis of the results and conclusion.
In the story shown in the question above, we can see the phases called observation and questioning. The observation takes place the moment Fleming noticed a fungus capable of growing on colonies of bacteria that cause throat infections, killing them. This observation made him enter the questioning phase, when he wondered if the fungus was able to prevent the growth of these bacteria.
Explanation:
The modern theory of chemical evolution is based on the assumption that on a primitive earth a mixture of simple chemicals assembled into more complex molecular systems, from which, eventually came the first functioning cell(s).
Convert the mixed numbers into improper fractions and divide:
134 2/5 = 672/5
11 1/5 = 56/5
5/672 * 5/56 = <span>25/37632
the answer is </span>25/37632
