Basically, Benedict's test identifies the existence of aldehydes and alpha-hydroxy-ketones, also by hemiacetal, as well as those that take place in specific ketoses. Therefore, it is an alpha-hydroxy-ketone even if the ketose fructose is not strictly a reducing sugar, and provides a positive test since it is transformed into the mannose and aldoses glucose by the base inside the reagent.
Answer: B (130)
Explanation:
A trapezoidal Riemann sum can be found by multiplying the width (the change in x) of each sub interval by the average of the y values of the two points at either end of the section and then adding up all of the sun intervals. Therefore, the trapezoidal approximation would equal 0.5(40) + 1.5(50) + 1(35) to get the answer of 130.
Answer:
Isolationism
Explanation:
In the 19th century, the United States under the administration of George Washington established a policy to isolate itself from intervening in foreign wars. There were deliberations as to whether the United States will join the League of Nations and interfere in wars. This policy was a result of the economic crisis faced by the United States at that time and there was a need to focus on the problems than getting involved in foreign affairs. Thomas Woodrow Wilson assuming power as the President of the United States, also maintained that stance as he urged the United States not to involve in wars.
Wilson changed his mind after he realized the war in Europe will most likely extend to the Atlantic Ocean. The number of people killed in the war also propelled the intervention of the United States. Its strong alliance in maintaining peace and stability in all states was also a key factor. With this intervention in the World War, the United States assumed the status of World power.
