Answer: Family planning is a measure that can help control the number of babies around the world.
Explanation:
High birth rates tend to occur regularly in countries where there is a high rate of poverty in various environments. These people who are in these environments generally have a low level of education and few resources, which do not allow them access to greater knowledge about the importance of planning.
To control the growth of the world population it is necessary to educate the people. Families should be taught about the importance of having a number of children and how more can affect various aspects of their family. The birth of a baby is something that in most cases generates emotion but when it is done without consciousness, where the parents do not think how their current situation can affect the baby, it is something that will bring negative results for everyone.
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.
