Because this is necessary for the data to be valid. If you are testing one variable but the conditions of the control and experimental are different besides that variable, you will have more than one variable and will not be able to tell if the results of the experiment are caused by the variable you were trying to test.

(Sorry for repeating the word variable so much, lol)

Answer:

The correct answer is option b. "20 H1, 40 H2A".

Explanation:

Chromatin is a complex that protects and condenses the genetic material comprised of DNA and proteins. When chromatin is in the form of a 30 nm fibril, nucleosomes have a regular positioning along the DNA. This means that each nucleosome is associated with a single H1 molecule. Therefore a chromatin containing 20 nucleosomes will have 20 copies of H1 and 40 copies of H2A, because each nucleosome has 2 copies of the core histone H2A.
