If dichloromethane is swapped out and ethyl acetate is used in its place, the extracts then obtained would be highly anti-radical and would be more efficient than dichloromethane.
Since "like dissolves like," ethyl acetate is a polar molecule that works well as a solvent to extract the polar caffeine molecules from coffee beans. The ethyl acetate molecules bind to the caffeine molecules, which then move through the bean cells' cell membranes. After all, the ethanol:water (1:1) solvent combination has been demonstrated to be the best for recovering catechins and delivering extracts with the highest antiradical activity.
Dichloromethane is a volatile colourless liquid used as an organic solvent in many industries. One of its main application is that it used to extract caffeine because of its highly effective solvent nature. Because DCM is a non-polar solvent and caffeine is readily soluble in DCM, it can easily be extracted without losing its aroma.

Answer:
b. journal articles
c. experimental data
Explanation:
In any report writing, if any reference is mentioned or quoted in the body of the report, it should be listed in the reference section of the report. Thus while making laboratory report, various information can be used while preparing the report taking help from other sources.
For example, the value of some experimental data such as the value of acceleration due to gravity, electron's mass, Planck's constant, Universal Gas constant, etc. can be used from other sources while making a laboratory report.
Also we take references from various articles of journals to present our content in the report
So these data should be cited in the reference section of the report.
Hence the correct option is (b) and (c).
Nazi concentration camps were work camps that were run by Hitlers SS police. These camps were set up to hold prisoners while torturing them or using them for work. These are not the same as extermination camps which were used for the mass killings of Jews.
Most prisoners were anything labeled "undesirables" such as German Communists, Socialists, Social Democrats, Jehovah's Witnesses, homosexuals, and persons accused of 'asocial' or socially 'deviant' behavior by the Germans (criminals), Jews, Soviets, disabled people, and clergymen.

Answer:
C. Often requires many years of study, training, and practical counselling experience.
Explanation:
Synthesizing the approaches covered in the text are time-consuming and require in-depth knowledge and practical experience. Otherwise, the results turn out to be ineffective and meaningless. This is why it requires a lot of study, training, and first-hand experience in the field of counselling. If you do not go through any of these then you would be unable to carry out the process in a proper manner in practical life.
