Answer:
In eukaryotes, nucleosomes play major roles in chromatin organization and gene expression
Explanation:
In eukaryotic organisms, chromosomal DNA is packaged with the help of proteins called 'histones' to form chromatin. The nucleosomes represent the basic packing units of the chromatin. Each nucleosome is composed of a histone octamer containing each two histones H2A, H2B, H3 and H4 wrapped around by 147 bp of DNA. Nucleosomes act as scaffolds to form higher-order chromatin structures (i.e., 30-nm chromatin fibers and condensed chromosomes). Moreover, nucleosome histone proteins can be chemically modified at defined amino acid residues, and thus nucleosomes also provide an epigenetic layer of information that can promote or inhibit gene expression.

Pathology refers to the study of structural and functional changes that occur in the body as a result of a disease. - True
The rest are false for the following reasons:
The vast majority of microorganisms, including the billions that inhabit the human body, are not pathogenic. However, an excess of certain microbes that are normally found in an individual can lead to an inection, which can lead to disease. Overuse of antibiotics, or improper use of antibiotics can lead to increases in populations of abnormal microorganisms that can cause infection and disease. In some cases, mutation within the normal microbiota can lead to infection and serious disease.
