Gel electrophoresis is a technique used to separate DNA fragments (or other macromolecules, such as RNA and proteins) based on their size and charge. Electrophoresis involves running a current through a gel containing the molecules of interest.
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.
Amino acids are the monomers that make up proteins. Amino acids are made of a carboxyl group (Carbon, Oxygen, Hydrogen), an amino group (Nitrogen and two Hydrogen), and finally an R group which differs in each amino acid. That R group is what makes each amino acid different! They can also act as enzymes. Essentially enzymes act as biological catalysts and control the functions of the cell and build cells.
I think B is answer because Boiling point is a physical property.
The speed of sound wave is slower than electromagnetic wave.
