Answer:
A general decrease in transcriptional activation
Explanation:
When acetyl groups are added to histone proteins by acetyltransferase enzymes, the 30-nm chromatin fiber will not be formed because the proteins are prevented from doing so. This further destabilizes the chromatin structure and allows the occurrence of transcription. However, raising the cells to 40°C does not allow the acetyltransferase enzyme to function and hence the acetyl group will be hindered from being added to the histone protein which is the main target of the enzymes. Thus, transcription activation will be blocked because the chromatin and nucleosomes would remain stabilized.
Cohesion occurs when molecules of the same substance are attracted to each other.

Diminishes,
A perfect example is humans on the earth, with our population rapidly growing eventually the earth will not be sufficient enough to humans.
