Having blood glucose levels that are too high or too low is very dangerous. Having a blood glucose level that is too high results in high blood pressure. Having a low blood glucose level causes hypoglycemia. Hypoglycemia causes symptoms like dizziness, fatigue, exessive sweating, and shaking.
Chemical messengers and the Electrical signals are the two main methods by which cells communicate with each other to coordinate their functions and metabolic activities.
According to biologist, A cell communicates through chemical messengers, by sending the chemical signals to other cells and also receive that signal from another cell. Similarly, Electrical signals or impulses also work in the same way.
Therefore, body contains many types of lipids which works as a chemical messengers also electical signal or impulses can easily travel throught these lipids. Cell uses these chemical messengers and electrical impulses to communicate with other cell. Although, In order to trigger a response, these signals are transmitted across the cell membrane of the cell.

Answer:
Option C, They allow random distribution of genetic material when a cell divides.
Explanation:
The chromatin are responsible for packaging of DNA molecule into smaller space with in a chromosome. It not only package it but also protect it from. Packaging allows for easier division of cells during mitosis and meiosis and hence prevent any kind of damage to the DNA.
Chromosomes make recombination and random segregation of genetic material to form new cells. Each new cell gets equal number of chromosomes
Hence, option C is correction
