Otrada [13]

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.

Explain how a crime lab could use paper chromatography to determine if lipstick found at a crime scene matched the lipstick of a
FromTheMoon [43]

Explanation:

The lipstick from the crime would be crushed and dissolved in an appropriate liquid solvent. The lipstick would then be placed in one of the ink spots on the starting / base line of the paper. Another spot would be created for the lipstick with which it is being compared with.

The paper chromatogram would then be placed vertically on a solvent that acts as the mobile phase. After some time, when the solvent reaches the solvent front  of the paper chromatography, by capillary action, the chromatogram can be removed and left to dry.

Bands will have appeared on the chromatography paper formed from the different components of the lipstick. The bands of the lipstick from the crime scene and that with which it is being compared to are observed. If the bands are all aligned, horizontally, then this means it is a complete match. The lipstick must have been the same used at the crime scene.
