Answer:
E = The activation energy barrier for this reaction can not easily be surmounted.
Explanation:
Starch:
Starch is a polymeric carbohydrate consist of various glucose units join together through glycosidic bonds.
Reason why it is not dissolve at room temperature:
When starch is added into water it form granules with cold water and can be soluble by heating.
At a room temperature the starch does not readily decompose to from the solution by decomposing into simple sugar because the activation energy barrier for this reaction can not easily be surmounted at a room temperature.
Answer:
Research.
Explanation:
Research may be defined as the study regarding the problem by using scientific methods. The inductive and deductive methods can be used in the research.
The knowledge of human behavior can be obtained through research. This helps the sociologist to move beyond the guesswork and increase in understanding the common sense in society.
Thus, the answer is research.
Answer:
B
Explanation:
Protons of atoms are the atomic particles with a positive charge while electrons bear a negative charge. Protons are found in the nucleus together with neutrons (that have no charge). They are held together by strong nuclear forces that overcome the repulsive forces between the positive charges in the nucleus. The electrons orbit around the nucleus and are kept in orbit by the electromagnetic attraction of the positive nucleus.
