The answer is;
a. add electric current.
b. add buffer solution
The process of gel electrophoresis taps on the property of net charges of molecules to ensure that they travel up the gel. Additionally, the buffer acts as the mobile phase for the molecules and also give molecules net charge as they travel through the gel. It is until the molecules reaches an isoelectric point,where the molecule has zero net charge, that they stops moving through the gel. This is how bands are formed.
Which of the following bio molecules typically contains both nitrogen and phosphate?
The answer to this question would be nucleic acids. That is because they contain a phosphate base and a nitrogen group.
You should post the diagrams but basically there are more cells than tissues and more tissues than organs
This is my opinion- please note this is NOT a fact:
Scientists label planets and dwarf planets to further distinguish what actually classifies a planet. If scientists didn’t have a classification system, the argument could be made that solid matter in space could be named a “planet” (asteroids, moons, etc.). Having certain classification thresholds means that planets that could support life are identified.
Again- this is NOT fact, my simple opinion. I could be very wrong.
