Answer:
You will measure the rate of your pules and how fast its going.
You need to keep the thing you are doing for example( if your running you have to make the people run the same length as every one else.
I hope this helps :)
Explanation:
The three situations in which ionic reactions go to completion is formation of a gas, a precipitate and a slightly ionized product.
<h3>What are ionic reactions?</h3>
It indicates the flow of electrons and, therefore, the bonds broken and formed in the course of the reaction. It is theoretical, it can be corroborated by experiments, but sometimes there is no consensus on the mechanism by which a certain reaction occurs.
Chemical reactions are the result of the transformation that occurs in substances, where atoms rearrange themselves, modifying their initial state. Thus, chemical compounds undergo changes generating new molecules. In turn, the atoms of the elements remain unchanged.

Answer:
A. The chromatin near cis-regulatory sequences will be more closed and there will be less transcription.
Explanation:
In the presence of histones, the cis-regulatory sequences of DNA like promoter, enhancers etc. are not exposed. The function of the histone acetyltransferases (HATS) is to cause chromosome decondensation i.e. removal of histones from the DNA so that transcription of the DNA could occur. Histone acetyltransferases (HATS) cause acetylation of lysine amino acid of the histone proteins. Acetyl group is negatively charged so the acetylation of histone proteins leads to the removal of their positive charge which ultimately leads to the decrease in the interaction between N terminal of histones and negatively charged phosphate group of the DNA molecule. As soon as histones are removed from the DNA where cis-regulatory sequences are located, the DNA becomes accessible for transcription.
But here a drug has been added which blocks the activity of histone acetyltransferases (HATS) in cancer cells. So it is quite evident that in these cells, histones will not get removed from the cis-regulatory sequences of DNA so the DNA will be more closer or tightly packed as a result of which less transcription will occur.
