<u>Stomach</u> is the part of the GI tract does not actively participate in the digestion of carbohydrates.
Carbohydrates are first mechanically and chemically broken down in the mouth. Mastication, another term for chewing, breaks down the meals high in carbohydrates into ever-tinier bits. Saliva that covers the food particles is produced by salivary glands in the mouth cavity. Salivary amylase is an enzyme found in saliva.
Dietary carbohydrates are converted to glucose, fructose, and/or galactose in the small intestine and then absorbed into the blood. The breakdown and absorption of dietary carbohydrates can be influenced by a variety of factors.

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.
A) Net movement in osmosis is from areas of higher water concentration to areas of lower water concentration. Net movement in diffusion occurs from areas of higher solute concentration to areas of lower solute concentration.
This happens so that both solution have roughly the same concentration
