Answer:
Results in the remodeling of chromatin that can activate or inhibit gene expression
Explanation:
Alteration of histones by addition of methyl and acetyl groups are examples of chromatin remodeling complexes. These allows for the remodeling /alteration of the chromatin state to allow transcriptional machinery and other cellular processes to have access to the DNA. This way, they can either activate or inhibit gene expression. Methylation patterns inhibits gene expression while acetylation activates gene expression and so on.
Effects on Waterways
Fertilizers contain large amounts of nitrogen and phosphorus. When these chemicals runoff agricultural fields into waterways, they can lead to accelerated growth of aquatic plants. Nutrients from fertilizer runoff encourages the growth of nuisance algae through the process of eutrophication.
Both the sodium and the chlorine atoms need to obtain a stable electron configuration, thus, a complete outer shell of eight electrons.
Sodiums electron design is 2,8,1 and chlorines electron setup is 2,8,7. So all together for the two molecules of the two components to get a total external shell of eight electrons, sodium will give one electron to chlorine, and the chlorine particle will acknowledge the gave electron when responded with each other.
This outcomes in the sodium particle having an electron arrangement of 2,8 so is currently total. The chloride particle currently has an electron configuration of 2,8,8.
Since the molecules have moved toward becoming particles to end up stable, the Na+ and the Cl-particles draw in one another because of their contrary charges, which results in an ionic bond.
This is the reason sodium and chlorine cling to each other when responded.
Your answer is False
