Explanation:
Histones are proteins that bind to the DNA in order to form highly compacted structures named nucleosomes, the basic structural units of DNA packaging in eukaryotic genomes. A nucleosome is a segment of DNA wound around an octamer (8) of histones, i.e., two copies each of the histones H2A, H2B, H3, and H4. These histones are positively charged in order to interact with the negatively charged DNA molecule. During transcription, reducing histone positive charge decreases the interaction between DNA and histones in the nucleosomes, thereby opening the chromatin to favor the access of the transcriptional complex and thus facilitates gene expression.
Endocrine glands are those that release regulatory chemicals inside the body. Choices A, B, and D are examples of endocrine glands. C mentions sebaceous glands, which are found in the epidermis of the skin and secrete sebum (skin oils) onto the surface of the skin. They have no regulatory function, other than to lubricate and protect the skin. Sebaceous glands are exocrine glands, and are not part of the endocrine system.
When influenza occurs in unusually large in numbers over the specific area it is called a/an epidemic
An epidemic in influenza is most different from that dreaded of pandemic that scientists and the world health officials fear is the nigh. We might see an epidemic of the seasonal influenza and during any given year. In fact, we just had that one.
Flu reached the epidemic levels in the U.S. and for the 10 weeks in a row during the 2004-2005 seasons 5, 8.9% of all the deaths reported in the 122 U.S. cities were due to the influenza and the pneumonia (a common complication of the flu).
